Airlines cancel flights after volcanic eruptions. An aviation expert explains why that’s a good thing

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/patrick-murray-2027113">Patrick Murray</a>, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a> At least three airlines <a href="https://www.abc.net.au/news/2024-11-13/flights-to-and-from-bali-cancelled-due-to-volcanic-ash/104593698">cancelled flights between Australia and Bali</a> this week after a volcano eruption in eastern Indonesia spewed a vast plume of volcanic ash into the air. But while would-be holiday makers are naturally <a href="https://7news.com.au/sunrise/volcanic-eruption-in-indonesia-forces-airlines-to-cancel-flights-to-bali-stranding-frustrated-passengers-c-16732486">upset</a> at having their plans disrupted, it’s worth remembering it’s not safe to fly planes through volcanic ash. So, how do airlines decide it’s not safe to fly when a volcano erupts? And why is volcanic ash so dangerous for aircraft, anyway? <h2>What does volcanic ash do to a plane?</h2> Volcanic ash particles are very, very abrasive. They can cause permanent damage to windscreens in the aircraft and can even make windscreens look opaque – like someone has gone over them with sandpaper. Imagine getting spectacles and scraping them over and over with sandpaper – that’s what you’d see if you were sitting in the cockpit. Volcanic ash can also clog or damage external sensors, leading to erroneous readings, and can infiltrate an aircraft’s ventilation system. This can affect cabin air quality and lead to potential respiratory issues. But the main issue, in fact, is the impact volcanic ash has on engines. A jet engine works by drawing in air, compressing it, mixing it with fuel and igniting it. This creates high-pressure exhaust gases that are expelled backward, which pushes the engine (and the aircraft) forward. The correct balance of fuel and airflow is crucial. When you disrupt airflow, it can cause the engine to stall. Ash particles that get inside the engines will melt and build up, causing disruption of the airflow. This could cause the engine to “flame out” or stall. Volcanic ash has a lot of silica in it, so when it melts it turns into something similar to glass. It won’t melt unless exposed to very high temperatures – but inside a jet engine, you do get very high temperatures. There was a famous incident in 1982 where a <a href="https://theaviationgeekclub.com/the-story-of-british-airways-flight-9-the-boeing-747-that-lost-all-four-engines-due-to-volcanic-ash-yet-it-landed-safely/">British Airways Boeing 747 plane</a> was flying in the vicinity of Indonesia and lost all four engines after it encountered volcanic ash spewing from Java’s Mount Galunggung. Fortunately, the pilot was able to <a href="https://simpleflying.com/gallunggung-glider-the-story-of-british-airways-flight-9/">restart the engines and land safely</a>, although the pilots were unable to see through the front windscreens. <h2>How do airlines decide it’s not safe to fly when a volcano erupts?</h2> The decision is made by each airline’s operational staff. Each airline’s operational team would be looking at the situation in real time today and making the decision based on their risk assessment. Every airline has a process of risk management, which is required by Australia’s Civil Aviation Safety Authority. Different airlines may tackle risk management in slightly different ways; you might have some cancelling flights earlier than others. But, in broad terms, the more sophisticated airlines would come to similar conclusions and they are likely all communicating with each other. Mostly, they make the call based on the extent of the plume – how big the cloud of ash is and where it’s going, bearing in mind that winds vary with altitude. As you get stronger winds with altitude, the ash can drift quite far from the source. There is also a United Nations agency called the <a href="https://www.icao.int/Pages/default.aspx">International Civil Aviation Organization</a>, which issues guidance on volcanic ash hazards. Various meteorological agencies around the world work together and liaise with aviation authorities to spread the word quickly if there is an eruption. For airlines to resume flights, the ash needs to clear and there needs to be a low probability of further eruptions. <h2>Passenger safety is the priority</h2> The underpinning reason behind these flight cancellations is safety. If you lose engines and you can’t see out the window, the risk to passenger safety is obvious. Naturally, people are upset about their holiday plans being held up. But it’s actually in passengers’ best interests to not fly through volcanic ash.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/243576/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/patrick-murray-2027113">Patrick Murray</a>, Emeritus Professor of Aviation, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Passenger arrested for assaulting flight crew member

A man has been arrested after being removed from an international flight for allegedly assaulting a member of the cabin crew. Onboard a flight from Perth to Auckland on early Wednesday morning, the Australian Federal Police were alerted to a passenger who was allegedly intoxicated and disruptive. The 23-year-old man from New Zealand allegedly assaulted a crew member, after staff alleged the man refused to comply with crew member requests during the flight. The flight was diverted to Melbourne Airport, with AFP officers boarding the plane to remove the man, who injured the cabin crew member during the assault. He was restrained at the back of the plane, with AFP Superintendent Stephen Cook confirming the flight was delayed as a result of the incident. “Any violence or anti-social behaviour in a confined space in the air would be distressing for other passengers and crew,” Superintendent Cook said. “At the very least, in this alleged incident it disrupted everyone’s travel plans." “Anti-social behaviour during a flight can pose a direct threat to the safety of the aircraft that is taken seriously by airlines and the AFP.” The 23-year-old man has been charged with one count of assaulting crew affecting the performance of their duty.

What to claim for lost, delayed or damaged bags on overseas flights

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/rebecca-johnston-123333">Rebecca Johnston</a>, <a href="https://theconversation.com/institutions/university-of-notre-dame-australia-852">University of Notre Dame Australia</a> and <a href="https://theconversation.com/profiles/david-hodgkinson-6574">David Hodgkinson</a>, <a href="https://theconversation.com/institutions/the-university-of-western-australia-1067">The University of Western Australia</a> If you get on a plane and your baggage ends up being delayed, damaged or lost, who’s responsible: you or the airline? And what rules apply when you’re flying between different countries – even if you don’t have travel insurance? Airlines (otherwise known as carriers) generally include baggage requirements in their terms and conditions of carriage, which are set out or referred to on your ticket. These are the rules that apply to the journey that you have booked. But for international flights, a carrier’s liability for damage, loss or delay of baggage is governed by a number of overarching international treaties, which many passengers aren’t aware of. <h2>International agreements</h2> The <a href="http://www.jus.uio.no/lm/air.carriage.warsaw.convention.1929/doc.html">Warsaw Convention</a> of 1929 was the first of these treaties, and the latest is the passenger-friendly 1999 <a href="http://www.jus.uio.no/lm/air.carriage.unification.convention.montreal.1999/">Montreal Convention</a>. In order for one of these treaties to apply to a particular journey, the same treaty must be in place at the point of departure and the passenger’s final destination. For many trips, the agreement that will apply will be the Montreal Convention, which has to date <a href="http://www.icao.int/secretariat/legal/List%20of%20Parties/Mtl99_EN.pdf">108 state parties</a>, covering everywhere from Albania and Australia to Zambia. In time, the Montreal Convention is expected to apply to almost all air travel. The Warsaw Convention (as amended by the <a href="http://www.jus.uio.no/lm/air.carriage.warsaw.convention.hague.protocol.1955/doc.html">Hague Protocol</a> and <a href="http://www.jus.uio.no/lm/air.carriage.warsaw.convention.montreal.protocol.4.1975/doc.html">Montreal Protocol No. 4</a>) will generally apply where the Montreal Convention does not. It is less favourable to passengers. All these treaties have similar provisions to deal with baggage claims – but very different limits to what you might get if you need to make a claim. <h2>What the airline is responsible for</h2> A carrier is liable if your checked baggage is lost, delayed or damaged regardless of fault. This is so unless the damage resulted from the inherent defect or quality of the baggage or, in terms of delay, if it proves that it took all reasonable measures to avoid the damage occasioned by that delay. As for unchecked baggage (that is, carry-on baggage), the carrier is only liable if the damage is due to the fault of the carrier or its agents. Unless otherwise specified, reference to “baggage” includes both checked and unchecked baggage. <h2>Calculating baggage compensation</h2> Under the Warsaw Convention (as amended by the <a href="http://www.jus.uio.no/lm/air.carriage.warsaw.convention.hague.protocol.1955/doc.html">Hague Protocol</a> and <a href="http://www.jus.uio.no/lm/air.carriage.warsaw.convention.montreal.protocol.4.1975/doc.html">Montreal Protocol No. 4</a>) and the Montreal Convention, liability limits are expressed in <a href="http://www.imf.org/external/np/exr/facts/sdr.HTM">special drawing rights</a> (SDRs). An SDR is a type of foreign exchange reserve asset created by the International Monetary Fund. Its value is based on an artificial basket of currencies consisting of the US dollar, the euro, the pound and the Japanese yen. The liability limits are reviewed every five years. As of October 16, 2014, the <a href="http://www.imf.org/external/np/fin/data/param_rms_mth.aspx">value of an SDR</a> is about US$1.49, £0.93 or A$1.70. Current SDR values for other currencies are also listed <a href="http://www.imf.org/external/np/fin/data/param_rms_mth.aspx">here</a>. <h2>So what is your baggage worth?</h2> In terms of baggage liability limits, the Warsaw Convention is of relatively little assistance to passengers. If your international travel is subject to Warsaw (for example, if you flew out of the United States on a one way ticket to Guatemala), liability for delayed, damaged or lost baggage is limited to 17 SDRs (about US$25.33, £15.81 or A$28.90) per kilogram per passenger for checked baggage and 332 SDRs (about US$494.68, £308.76 or A$564.40) per passenger for unchecked baggage. In contrast, a carrier is liable to pay far greater damages if the Montreal Convention applies. For any travel covered by Montreal, the carrier’s liability for baggage is limited to 1131 SDRs per passenger (US$1685.19, £1051.83 or A$1922.70), unless otherwise declared. The carrier is not liable for damages caused by delay if the carrier took all reasonable measures, or if it was impossible for it to take such measures. <h2>Time limits on baggage claims</h2> Time limits are imposed on making a claim for delayed, damaged or lost baggage. Any potential claims should be made to a carrier in writing within these specified limits. Article 26 of Warsaw provides that any complaint as to delay of baggage must be made at the latest within 21 days from the date the baggage was placed at the passenger’s disposal. <figure class="align-right zoomable"></figure> Similarly, under Article 31 of Montreal, a complaint must be made within 21 days of a passenger receiving their baggage. With respect to damaged baggage, under Warsaw, any claim must be made “forthwith” after the discovery of the damage and at most seven days from the date of receipt of the baggage. Montreal also gives passengers seven days from receipt of checked bags to report a damage claim. Neither convention imposes a time limit for reporting lost baggage claims. But it is advisable that you make your complaint as soon as possible. Warsaw does not state when baggage is considered “lost”, leaving it up to carriers to make that ruling. Under Montreal, baggage is only considered lost after 21 days or if the carrier admits that they have lost it. If a passenger fails to make a complaint within the specified times, the carrier will not be liable unless there has been fraud on the carrier’s part. <h2>Insurance alternatives</h2> If you are concerned that the contents of your baggage exceed the liability limits outlined above, you can make a special declaration of the value of your baggage prior to check-in and pay any additional fee (if required). In this case, the carrier will be liable to pay a higher amount, unless it is proved that the declared amount is greater than the actual value of your baggage. Alternatively, prior to travelling, check with your insurance company as to whether your travel insurance covers any excess from delayed, damaged or lost baggage. You might also want to <a href="http://www.icao.int/secretariat/legal/List%20of%20Parties/Mtl99_EN.pdf">check this list</a> to see whether the places you’re departing from and finally arriving at are parties to the Montreal Convention. If not, you might just find yourself out of pocket.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/32111/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/rebecca-johnston-123333">Rebecca Johnston</a>, Adjunct Lecturer, Law School, <a href="https://theconversation.com/institutions/university-of-notre-dame-australia-852">University of Notre Dame Australia</a> and <a href="https://theconversation.com/profiles/david-hodgkinson-6574">David Hodgkinson</a>, Associate Professor, Law School, <a href="https://theconversation.com/institutions/the-university-of-western-australia-1067">The University of Western Australia</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Pilot dies mid-flight prompting emergency landing

A Turkish Airlines pilot has tragically died in the middle of a flight from Seattle in the US to the Turkish city of Istanbul, prompting an emergency landing. Pilot İlçehin Pehlivan, 59, “lost consciousness” at some point after the flight took off, with the plane then landing in New York’s John F. Kennedy International Airport, almost five hours into the journey. The diversion came after initial medical intervention on board failed to revive the captain, with the second pilot and co-pilot making the landing in New York. Pehlivan was declared dead on arrival when the plane was met by authorities, and no cause of death has yet been released. Turkish Airlines spokesperson Yahya Üstün said the pilot, who worked for the airline since 2007, underwent a routine health check in March and “no health problem was detected that would prevent him from working”. He recalled the moment onboard, saying, "After the first medical evaluation to our captain on board was inconclusive, the cockpit crew ... decided to make an emergency landing, but our captain died before landing." “As Turkish Airlines, we deeply feel the loss of our captain and extend our sincerest condolences to his bereaved family, colleagues, and all his loved ones,” he added.

Qantas faces the music for selling seats on cancelled flights

Qantas has been fined a whopping $120 million for purposefully misleading customers on flight bookings for several years. After being sued by the Australian Competition and Consumer Commission (ACCC) over dishonest conduct relating to the sale of tickets on cancelled flights, the airline admitted they were deceiving travellers by continuing to sell tickets on flights that had already been cancelled. On Tuesday, Justice Helen Rofe formally ordered Qantas to pay a $100 million fine for their conduct, and another $20 million to travellers who were affected. Qantas agreed to pay $225 to affected customers on domestic flights and $450 on international flights. "This is a substantial penalty, which sets a strong signal to all businesses, big or small, that they will face serious consequences if they mislead their customers," ACCC chair Gina Cass-Gottlieb said in a statement following the court orders. Earlier this year, Cass-Gottlieb described Qantas’ conduct as “egregious and unacceptable”, after data showed that between May 2021 and August 2023, the airline sold tickets on cancelled flights to more than 86,000 customers. In addition to cancelling the flights, the airline also failed to inform travellers that their flights were no longer going ahead as scheduled. ACCC barrister Christopher Caleo claimed that some senior airline managers knew about different aspects of the issue, including the fact that cancelled flights were not removed from booking pages or that customers could still book those flights, but no single manager was aware of the severity of the issue. "Qantas was aware of deficiencies in their systems," Caleo said. "Despite their awareness, it persisted over an extended period of time and affected a large number of consumers." Caleo added that the sizable fine presented to Qantas was required in order to deter them from any further devious conduct. "A penalty must send a signal to other companies in Australia, particularly to other large companies, that contraventions of Australian consumer law will not be tolerated," he said. "It must sting and must not be an acceptable cost for Qantas for failing to have systems in place." Qantas said it has made changes to its systems and agreed to notify customers of cancelled flights no longer than 48 hours from cancelling a flight and stop selling tickets for those journeys within 24 hours, with these changes also taking effect with subsidiary Jetstar. "The fact that Qantas made these changes makes it clear that Qantas wants to avoid the matter from occurring again," barrister Ruth Higgins said. Image credits: Shutterstock

Parents under fire for taking their sick toddler on a long-haul flight

A couple has come under fire after documenting their experience online of boarding a long-haul flight with their toddler, despite the child being sick. Alina and her husband were excited to go on their long-awaited holiday to Thailand with their one-year-old son in tow, taking off on their first big family trip. However, shortly before they were set to take off, their child developed a raging fever, and they decided to go on the trip anyway. Taking the experience to social media, Alina said her son’s temperature soared to around 40 degrees, with their little boy’s condition escalating so rapidly that the parents were considering calling off their entire trip. “My husband and I even wanted to cancel the flight,” she confessed in the video, which has received around 1.4 million views. However, after realising they would be out of pocket by several thousands of dollars if they cancelled the trip at such short notice, they decided to take the risk and board the plane. “Our tickets would have been wasted, and the trip that cost us $3,000 would have been wasted,” the mum wrote. "One plus of this flight was that the flight was at night, and the child could sleep and recover.” In the clip, the parents were seen walking their son around the plane, cradling the sick toddler as he cried uncontrollably. Luckily, the parents “managed to bring down the temperature”, but they weren’t convinced their son would keep quiet for the rest of the trip. “We were so worried about how the baby would feel on an eight-hour flight,” she continued, walking the baby up and down the corridors of the airport, trying to calm him down. As they tried to settle the child, they realised that their hopes that he would sleep the whole way were misguided. “The flight turned out to be difficult,” Alina confessed. “The baby kept waking and crying.” In the middle of the night, their son’s fever returned, which forced the parents to “bring the temperature down again” and left them “very worried” about their son’s health. Their baby’s fever took a toll on the parents as well, who complained of feeling “squeezed like a lemon” while trying to keep his temperature down, as Alina recalled, “We took turns looking after the baby so each of us could sleep.” In a later video, the parents defended their choice to take their son on the flight despite his intense fever and blamed it on his teething, not sickness. “Our baby wasn’t sick, he was teething, and that’s why he had a fever,” she said. “If our child had been sick, we would have cancelled everything … I consider myself a wonderful mother.” Despite the mother's clarification of her son's fever, the parents were slammed for even considering taking a sick child on such a long flight. “It’s OK, don’t worry about making anyone else on that flight sick,” a sarcastic comment read. “This is so tremendously selfish, you are appalling for doing this to him and others.” “I was in the same situation,” another parent said. “I lost all bookings, but who cares, my daughter comes first always and forever, no matter the amount of money!” “Trips come and go; your baby’s health is priceless!” read another comment. “Forty degrees is a hospital admission! Not a flight to Thailand!” However, not everyone was as judgmental, with many parents extending their sympathies to the first-time parents, as one person wrote, “You know what’s best for your baby. Everyone will say things. But only you will know when you are in that situation.” “Everyone is a first-time parent,” another defended. “This was a lesson learned. A baby’s health is of utmost importance. No holiday is more important than that. I hope he is OK now.” Image credits: TikTok

"No show": Wild reason couple denied refund on flights scheduled during Covid

A Melbourne couple, who had booked flights with Qantas during the state's fifth lockdown, were left furious after they were told they were ineligible for a refund because they were a "no show". Kieran McGregor told news.com.au that he and his partner had originally booked the flights to Darwin for July 18, 2021 through travel giant Expedia. When the number of Covid cases started rising, he moved the flights forward to fly out on the 16th of July, hoping that they would be able to get out before another lockdown, but the day before their flight, Victorian Premier Daniel Andrews announced the state's fifth lockdown. Three years later, McGregor was still stuck between trying to get the refund from Expedia, who said Qantas had the money, and Qantas, who said the travel agent had it. Last year, McGregor contacted Expedia on their X account to try to resolve the issue, but the company said: “We just got off the phone with the airline, and as per advised, the ticket shows suspended on their end due to a no show." “Your ticket is no (sic) eligible for a refund, and has no value as per the airline. We apologize for the inconvenience.” He was "incredulous" when he received the message. “How could I fly if the state of Victoria was in lockdown and I couldn’t move more than 5km from the house?” he told news.com.au. When he contacted Qantas, the airline claimed “the funds will still remain with the agency that you’ve booked with” and to contact them directly for a refund. McGregor told news.com.au the ordeal was “utterly disgraceful” and that he was unaware if the flight went ahead or not. The publication reportedly contacted Expedia and Qantas and on Tuesday morning they finally said that a refund would be issued, but McGregor said he was yet to be contacted. “For flight bookings at Expedia, we generally follow the policies of our travel partners, so any refund is determined by the airline,” an Expedia spokeswoman said. “We have looked into this case with Qantas, and we will be contacting the traveller to process the refund.” While a Qantas spokesman said: “We apologise for the extended delay in resolving this issue and are processing a full refund for their bookings.” It is unclear which company held McGregor's funds, which was reported to be around $2,500. Adam Glezer from Consumer Champion told news.com.au that McGregor came to him recently when he felt he had nowhere else to turn. He said that these situations were quite common. “What Kieran has gone through with Expedia and Qantas is extremely common where the third party says the airline has the money and the airline says the third party has the money. I call it the blame game and there’s only one loser out of it and that’s the customer," he said. “Transparency in these situations is of utmost importance and unfortunately it just doesn’t exist.” Images: news.com.au/ DLeng / Shutterstock.com

Passengers on cancelled flights to be compensated under new reforms

Plane passengers could soon be entitled to compensation or refunds for delayed or cancelled flights in Australia. The long-awaited Aviation White Paper will be handed down this morning, as part of the federal government's crackdown on the aviation sector. The white paper makes 56 recommendations, including the the establishment of an Aviation Industry Ombudsman Scheme, which will have the authority to make it compulsory for airlines to provide support to passengers and give travellers more rights. The Aviation Industry Ombudsman Scheme will also be able to refer to allegations of misconduct for investigation and enforcement. It will also introduce a new "Charter of Rights" entitling airline customers to refunds for flights that are disrupted, cancelled, or unreasonably delayed. Infrastructure Minister Catherine King said the changes were critical to ensure that passenger had better experiences in the air, and will provide them with a baseline for the services they can expect on flights. "The aviation customer experience has deteriorated post-COVID, with an urgent need to better protect the rights of the travelling public," she said. She added that Australians were often not being dealt with fairly by airlines. "The bottom line is if people don't get the service that they are expecting, then customers deserve to get their money back or they deserve to get an equivalent service," she said. "And that's really not what's been happening when it comes to the consumer space." Under the Aviation Industry Ombuds Scheme, airlines will also have to "show cause" and provide a valid reason why a flight has been delayed or cancelled, and the ombudsperson has the right to request additional information. Airlines will also be required to provide support to people to make alternative travel arrangements. As part of its white paper, the government will also establish new minimum standards for airlines to make their services more accessible to those with disabilities. Legislation to establish the aviation ombuds office will be introduced next year, but the government plans to appoint an interim ombudsperson. The scheme is expected to be fully implemented in 2026.

Flight attendant shares travel tips for loved-up couples

A flight attendant has shared what loved-up couples should not do when taking a trip together. Seasoned cabin crew member Suzanne Bucknam has warned couples to be wary of appropriate behaviour, and advised against these travel “icks”. Suzie told <a href="https://www.skyparksecure.com/">SkyParkSecure</a>, that one thing couples should be aware of when travelling are public displays of affection (PDA), which could land you in trouble. "A kiss on the lips or handholding doesn't warrant ick status but making out and putting a blanket over each other's laps gets very uncomfortable for everyone in the vicinity," Suzanne explains. "I've seen several couples attempt to join the mile-high club either in the bathroom or, worse, at their seats with said blanket over them. In fact, I've caught a couple with their pants down in the back of our plane once. We did an emergency landing and had them escorted off the plane, then got back in the air without them.” "It should be known that you can be arrested for public indecency, and flight attendants won't be afraid to call the authorities if they see you trying to get too cosy with your partner." Another must do for travelling couples is to book your plane seats together, rather than ask other passengers to change seats. "A simple boarding process can become a nightmare if couples don't book seats together but demand another passenger to move," she says. "Not only does it slow the process down significantly, but it often causes an altercation between passengers when someone won't move. Someone picked and paid for that seat, so they are well within their right to turn down a request to switch." Suzie said that while she understands couples, especially honeymooners, are excited about their travels, that doesn’t give them the right to make demands, and being difficult will get you nowhere. "What I wish all honeymooners knew before travelling somewhere is that, just because they're celebrating, it doesn't mean others have to celebrate or contribute to that celebration. If you do get a free upgrade or a free drink, fantastic! But please don't demand one from an unsuspecting flight attendant," she explains. "And as an employee who has been in that situation, it's just plain awkward if there are no upgrades available, and it's against the airline's policy to give freebies." Image credits: Shutterstock

Passenger sparks debate over travellers sleeping in aisle seats

A heated debate has erupted online after a passenger suggested those sitting in an aisle seat should remain alert and awake for the entire flight, with the only exception being if it's a long-flight of seven hours or more. “A person sitting in an aisle seat on a plane should not be allowed to sleep," they wrote on Reddit. The reason behind it, according to the passenger, is to ensure that middle and window seat passengers can access the toilet, get served by flight attendants, and evacuate quickly in an emergency. “There are some exceptions and those would probably be on any flight longer than seven hours. “But anything shorter than that, you should not be sleeping. What if the middle or window passenger needs the bathroom, or if the flight attendant needs to hand them something – You’ll be in the way.” They added that a snoozing aisle seat passenger could potentially slow down evacuation during an emergency and put everyone at risk. “Now you would be risking people’s lives because you fell asleep,” they wrote. Social media users flocked to the Reddit thread to share their thoughts. “Nah, just poke me and wake me up if you need me to get up or do something," one wrote. “I’m well aware that I’m in the way, believe me. I’m certainly not there because I wanted to be in the aisle seat.” “If you sleep in an aisle seat, you deal with people getting up. That’s the unwritten rule," another added. A few others supported the idea, but shared their own take on plane etiquette. “My take on this: if you sleep in the aisle seat, you must be okay with being woken up multiple times to let the folks in your row get up. “Other flight rules: middle seat gets the armrest, and window seat must raise the window shade during taxi, takeoff, and landing so the rest of us in the row can watch.” Image: Shutterstock

Cause of death revealed after eight-year-old dies mid-flight

The cause of death of an eight-year-old girl who died suddenly mid-flight has been revealed. Sydney Weston was travelling with her family from their home state of Missouri to Chicago on June 13th when she suddenly fell ill on the flight and died. Now, according to Peoria County Coroner Jamie Harwood, Sydney was suffering from at least five different illnesses at the time of her death. The eight-year-old reportedly died from complications of chronic primary adrenalitis coupled with several infections, including enterovirus and strep, as well as inflammation of the small intestines known as duodenitis and the thyroid gland inflammation commonly known as thyroiditis. Harwood found that the long list of conditions suggests Sydney may have suffered from an autoimmune disorder which left her body attacking its own healthy cells and harming organ operation. Sydney suffered a medical emergency onboard the flight, causing the plane to divert to Peoria, Illinois, for an emergency landing, but Sydney died after being rushed to a nearby hospital. Results from a previously released preliminary autopsy were inconclusive but found that her body showed no signs of abuse, neglect or foul play. At the time of her sudden and tragic death, Sydney was just a week away from celebrating her ninth birthday. “She will forever be remembered for the happiness she brought to every single person she encountered. Our hearts are heavy. She was our baby girl and we celebrate her beautiful life,” her obituary read. Image credits: Instagram

If Australia had an aviation ombudsman, passengers could get compensation for cancelled flights

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/justin-wastnage-489752">Justin Wastnage</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> The financial difficulties of <a href="https://www.abc.net.au/news/2024-08-02/rex-airlines-staff-notified-of-termination/104172020">Rex Airlines</a>, coming so soon after the bankruptcy of <a href="https://www.abc.net.au/news/2024-06-26/bonza-directors-accused-of-trading-while-insolvent/104022496">Bonza</a>, have brought into sharp focus one of the federal government’s key priorities for aviation: enhancing passenger rights. In each case, passengers were left with tickets for flights that did not fly. In the case of Rex, tickets were honoured by rivals Virgin Australia and Qantas, possibly trying to recapture the small toehold Rex had established in the Brisbane-Sydney-Melbourne golden triangle. The Bonza story was more complex as the fledgling airline, which collapsed in May, had sought to exploit under-serviced routes to smaller leisure-based cities including Maroochydore and Port Macquarie. In many cases, passengers were left out-of-pocket and stranded. <h2>Support for an ombudsman</h2> These failures will have emboldened the federal government’s plans to introduce stronger passenger protections and an airline ombudsman. The release of its <a href="https://www.infrastructure.gov.au/infrastructure-transport-vehicles/aviation/aviation-white-paper">policy white paper</a> is imminent. The paper covers aviation issues including competition between airports and airlines, the sector’s environmental impact and better mechanisms for consultation. After years of opposition, <a href="https://www.travelweekly.com.au/article/qantas-and-virgin-change-tune-on-aviation-ombudsman-ahead-of-white-paper-release/">Qantas and Virgin quietly fell in behind the idea in May</a>, signalling a deal is close to being announced. The ombudsman is designed to protect consumer rights in what is often monopolistic or quasi-monopolistic operating environments. With the exception of residents of southeast Queensland and the western suburbs of Melbourne, <a href="https://www.sciencedirect.com/science/article/abs/pii/S0967070X18302063">most Australians only have one airport from which to fly.</a> This, coupled with an effective airline duopoly, can lead to higher prices and poorer service for consumers, the <a href="https://www.accc.gov.au/system/files/Airline%20competition%20in%20Australia%20-%20June%202023%20report.pdf">Australian Consumer and Competition Commission (ACCC)</a> has argued. The ACCC has been calling for better passenger rights for more than a decade. But its calls grew louder after it fined Qantas <a href="https://theconversation.com/qantas-has-finally-settled-its-ghost-flights-lawsuit-for-120-million-whats-next-229368">A$120 million for selling “ghost” flights in May</a>. Passengers did receive refunds, but the process was not easy compared to many overseas jurisdictions where compensation is automatic and based on distance travelled. Australia is rare among developed countries for not having automatic compensation if a flight is cancelled or delayed. <h2>The EU model</h2> The leader in air passenger rights, as in many areas of consumer protection, is the European Union. <a href="https://eur-lex.europa.eu/eli/reg/2004/261/oj">The EU Passenger Rights regulation</a> is 20 years old and now also applies to rail and bus passengers. The regulation favours the passenger and awards compensation <a href="https://www.airhelp.com/en-int/ec-regulation-261-2004/">of up to €600 (almost A$1,000) for delays or cancellations</a>. There are clauses for when a delay is unavoidable, but generally airlines have now built the scheme into their costs of doing business. The scheme is well publicised and in 2022, about <a href="https://schengen.news/8-million-passengers-affected-by-flight-cancellations-airport-strikes-are-eligible-for-compensation-of-up-to-e600/">eight million passengers were eligible for refunds</a>. Air passenger rights in the UK continued in the EU mould after Brexit and were even strengthened. But in a 2023 review into the UK scheme, <a href="https://www.gov.uk/government/consultations/reforming-aviation-consumer-policy-protecting-air-passenger-rights/outcome/response-to-the-aviation-consumer-policy-reform-consultation#chapter-3-compensation-for-delays-and-cancellations">some airlines argued</a> “private insurance was a better option for some passengers”, particularly those with disabilities. The same reasoning led to the removal of Australia’s previous consumer protection scheme for airline passengers, the <a href="https://www.travelmanagers.com.au/peaceofmind/#:%7E:text=The%20Travel%20Compensation%20Fund%20continued,and%20until%2030%20June%202014.">Travel Compensation Fund</a>, which refunded customers when airlines or travel agencies went bankrupt. The scheme was ended under the Abbott government in June 2014, with travellers told instead to take out their own travel insurance. Labor is expected to reintroduce an element of corporate responsibility for airline delays, not least since Brazil, Canada and Türkiye have also followed the EU’s lead. Brazil’s scheme is particularly generous, with up to R7,500 (A$1,950) available to passengers who have to pay for last minute accommodation if their flight is cancelled. Lawmakers there countered claims by airlines that low cost airline passengers could stay in cheaper hotels, by applying the compensation uniformly, regardless of travel class. <h2>Popular with voters</h2> Air passenger rights can be a vote winner, too. Before he withdrew his bid for reelection, US President Joe Biden trumpeted the <a href="https://www.transportation.gov/briefing-room/biden-harris-administration-announces-final-rule-requiring-automatic-refunds-airline">automatic airline compensation scheme</a> the US Department for Transportation will bring in this year. Until now, airline compensation was mandated by the states without coordinated processes meaning some airlines used vouchers, some credits and a few cash to compensate customers. Despite this, about <a href="https://www.transportation.gov/briefing-room/biden-harris-administration-announces-final-rule-requiring-automatic-refunds-airline">US$3 billion (A$4.6 billion)</a> in refunds have been issued to US passengers since 2020, including more than US$600 million to Southwest Airlines passengers alone. This was due to a serious scheduling crisis which forced the low-cost carrier to cancel almost 60% of its flights in the 2022 summer. By contrast, in Australia, air passengers have only had basic protections under <a href="https://consumer.gov.au/australian-consumer-law/legislation">consumer rights law</a> since deregulation in 2002. There is no guarantee of a seat or even flight the consumer purchased. This has led consumer advocates including <a href="https://www.choice.com.au/consumer-advocacy/policy/policy-submissions/2023/november/aviation-green-paper">Choice</a> to support calls for an airline ombudsman and automatic delay and cancellation compensation.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/235679/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/justin-wastnage-489752">Justin Wastnage</a>, Adjunct Industry Fellow, Griffith Institute for Tourism, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Flight cancelled after crew member loses it at passenger

An Air Canada flight heading from Morocco to Montreal was cancelled on Friday after a flight attendant lost it at a passenger who reportedly requested a blanket. Viral footage of the incident showed a female flight attendant yelling: “You will behave or we will get off!” at a female passenger. “I’ll tell the captain right away. Yes or no?” When a passenger asked the flight attendant to call the captain, she refused and said: “I don’t want no bullying against my crew”. She then stormed up the aisle before she turned around and yelled: “Everyone behave! Be quiet … or you’re getting off.” <blockquote class="twitter-tweet"> Stress levels are quite high in the sky these days : An Air Canada flight from Casablanca (CMN) to Montreal (YUL) was canceled due to the inappropriate behavior of a flight attendant on July 26, 2024.

So when should you book that flight? The truth on airline prices

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/yuriy-gorodnichenko-144556">Yuriy Gorodnichenko</a>, <a href="https://theconversation.com/institutions/university-of-california-berkeley-754">University of California, Berkeley</a> and <a href="https://theconversation.com/profiles/volodymyr-bilotkach-145437">Volodymyr Bilotkach</a>, <a href="https://theconversation.com/institutions/newcastle-university-906">Newcastle University</a> How airlines price tickets is a source of many <a href="http://airtravel.about.com/od/travelindustrynews/a/mythticket.htm">myths</a> and urban legends. These include tips about the best day of the week to buy a ticket, last-minute discounts offered by the airlines, and the conspiracy theories suggesting that the carriers use cookies to increase prices for their passengers. None of these three statements is entirely true. Studies have suggested that prices can be higher or lower on a given day of the week – yet, there is no clear consensus on which day that is. Offered prices can in fact drop at any time before the flight, yet they are much more likely to increase than decrease over the last several weeks before the flight’s departure. Further, the airlines prefer to wait for the last-minute business traveler who’s likely to pay full fare rather than sell the seat prematurely to a price conscious traveler. And no, the airlines do not use cookies to manipulate fare quotes – adjusting their inventory for specific customers appears to be beyond their technical capabilities. What is true about pricing in the airline industry is that carriers use complex and sophisticated pricing systems. The airline’s per passenger cost is the lowest when the flight is full, so carriers have incentive to sell as many seats as possible. This is a race against time for an airline and, of course, no company wants to discount its product more than it has to. Hence, the airlines face two somewhat contradictory goals: to maximize revenue by flying full planes and to sell as many full-fare seats as possible. This a process known in the industry as yield or revenue management. <h2>Airlines and their bucket lists</h2> Here is how <a href="http://commons.erau.edu/cgi/viewcontent.cgi?article=1522&context=jaaer">yield management</a> works. For each flight or route (if we are talking about multi-segment itineraries), the airline has a set of available price levels – from the most expensive fully refundable fare to the cheapest deeply discounted non-refundable price. The industry jargon for these prices is “buckets.” Then, seats can be interpreted as balls that are allocated among these buckets. Initial allocation of seats between the price buckets is determined by historical data indicating how well a certain flight sells. For example, fewer deeply discounted seats will be offered on a flight on Thanksgiving week than on the same flight during the third week of February. As the seats on a flight sell, yield managers monitor and adjust the seat allocation. If, for instance, the sales are slower than expected, some of the seats might be moved to lower-priced buckets – this shows up as a price drop. As noted above, such price drops can occur at any time before the flight. However, the general trend of price quotes is upward starting from about two to three weeks before the flight departure date. Of course, an average traveler wants to know when he or she should buy the tickets for the next trip. Another important question is where to buy this ticket. Airlines distribute their inventory on their own websites and on several computer distribution systems, meaning that prices can sometimes differ depending on where one looks. We are not entirely sure what precipitates this phenomenon – likely explanations include differences in contracts between the airlines and the distribution systems/travel agents, implying that different travel agents may not have access to the airline’s entire inventory of available prices. <h2>When to book</h2> The airlines’ yield managers start looking at flight bookings about two months before the departure date. This implies that it generally does not pay to book more than two months in advance: studies show that initially the airlines leave the cheapest price buckets empty, and yield managers may move some seats into those buckets if a couple of months before the departure date the flight is emptier than expected. Between two months and about two to three weeks before the flight date, the fare quotes remain mostly flat, with a slight upward trend. However, and perhaps paradoxically, there is a good chance of a price drop during this period. We tend to monitor prices for several days – sometimes up to a week – hoping for a potentially lower quote. It does not always pay off, but sometimes we do manage to save a considerable amount of money. Two to three weeks before the flight date, the price quotes start increasing. This is the time when business travelers start booking. While price drops are still possible, a chance of a price increase is much higher if you wait to book within this time period. This is also the time when one can find significant differences between price quotes, depending on where one looks and what contract they have with the airlines. Thus, if we book a trip earlier than three weeks before the flight date, we tend not to delay the purchase. At the same time, we check quotes from multiple travel agents, or go directly to a site that allows for a quick comparison of prices (such as <a href="https://www.kayak.com">kayak.com</a> or <a href="http://www.skyscanner.net">skyscanner.net</a>). Or check the airline itself. As for answering the original question we posed, here are some simple tips. First, if you have to travel during a peak period, such as Thanksgiving week, it is generally best not to delay buying that ticket. Otherwise, it might pay to monitor the offered prices for some time before committing. The best strategy for booking within the last couple of weeks before the flight, however, is not to delay the purchase, but to try getting quotes from several agents, which is easy to do in the internet age.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/34033/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/yuriy-gorodnichenko-144556">Yuriy Gorodnichenko</a>, Associate Professor of Economics, <a href="https://theconversation.com/institutions/university-of-california-berkeley-754">University of California, Berkeley</a> and <a href="https://theconversation.com/profiles/volodymyr-bilotkach-145437">Volodymyr Bilotkach</a>, Senior Lecturer in Economics, <a href="https://theconversation.com/institutions/newcastle-university-906">Newcastle University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Young woman dies on Qantas flight

A young woman has tragically died onboard a Qantas flight from Melbourne to the Indian city of Delhi. Manpreet Kaur, 24, boarded the international flight to visit her family for the first time in four years, but she never made it to her destination. According to a close friend, the student reportedly “felt unwell” hours before arriving at the airport but managed to board the flight without any issues. However, when she went to put on her seatbelt, Ms Kaur apparently fell to the floor and “died on the spot”. The plane was still grounded when Ms Kaur collapsed, as cabin crew and emergency services rushed to help her. “When she got on the plane, she was struggling to put her seatbelt on,” her friend Gurdip Grewal told the <a title="www.heraldsun.com.au" href="https://www.heraldsun.com.au/news/victoria/tributes-flow-for-student-who-died-on-qantas-flight-at-melbourne-airport/news-story/aaa561d3d6ab09d15bcf3533312abdab" target="_blank" rel="noopener" data-tgev="event119" data-tgev-container="bodylink" data-tgev-order="aaa561d3d6ab09d15bcf3533312abdab" data-tgev-label="news" data-tgev-metric="ev">Herald Sun.</a> “Just before her flight started, she fell in front of her seat and died on the spot.” According to reports from the Herald Sun, it is believed Ms Kaur died of tuberculosis, an infectious disease that mostly affects the lungs. Her roommate, Kuldeep, said Ms Kaur had worked at Australia Post while studying cooking, with dreams of one day becoming a chef. “She was kind and honest,” she told the publication. “She loved to travel with her friends around Victoria.” A <a title="www.gofundme.com" href="https://www.gofundme.com/f/smksq-manpreet-kaur" target="_blank" rel="noopener">GoFundMe</a> page has been created for Ms Kaur to help her family, as the fundraising page reads, “Our dear friend Manpreet left us too soon, leaving a void in our lives that can never be filled.” “As we grieve her passing, we want to come together to honour her memory and support her family in their time of need." “As we say our final goodbyes, every contribution, big or small, brings us closer to our goal. Your support means the world to us and Manpreet’s family.” A Qantas spokesperson told <a href="https://www.news.com.au/travel/travel-updates/incidents/woman-dies-on-international-qantas-flight/news-story/41934ac049c5f9712e37f3a2680b1e2a" target="_blank" rel="noopener">news.com.au</a> that their “thoughts are with her family and loved ones”.

Flight attendant reveals the unexpected reason why it's so cold on planes

When it comes to packing essentials in your carry-on for your next flight, many people add a jumper, extra socks, or even their own blanket to their bags. Because one thing’s for sure: you’ll probably be cold on your flight. But have you ever stopped to think of the reason why the cabin of a plane is so cold? According to a Canadian flight attendant, it's to do with keeping you feeling good. Vanessa Settimi told Reader's Digest that a cooler cabin helps passengers who are prone to fainting or have motion sickness during turbulence. She also clarified that despite what travellers may think, cabin crew don’t have control over the cabin temperature. "Temperature in the cabin is controlled by the pilots. Even though travellers often ask to get the temperature turned up during flights, it is kept on the cooler side." She went on to say that the key to staying warm on your next flight is bringing extra layers. "Now this might just be the flight attendant in me," says Settimi, "but you will never catch me flying as a traveller in sandals and a tank top!" Image credits: Shutterstock

How do airplanes fly? An aerospace engineer explains the physics of flight

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/craig-merrett-1509278">Craig Merrett</a>, <a href="https://theconversation.com/institutions/clarkson-university-4276">Clarkson University</a> Airplane flight is one of the most significant technological achievements of the 20th century. The <a href="https://airandspace.si.edu/explore/stories/wright-brothers">invention of the airplane</a> allows people to travel from one side of the planet to the other in less than a day, compared with weeks of travel by boat and train. Understanding precisely why airplanes fly is an ongoing challenge for <a href="https://www.clarkson.edu/people/craig-merrett">aerospace engineers, like me</a>, who study and design airplanes, rockets, satellites, helicopters and space capsules. Our job is to make sure that flying through the air or in space is safe and reliable, by using tools and ideas from science and mathematics, like computer simulations and experiments. Because of that work, flying in an airplane is <a href="https://usafacts.org/articles/is-flying-safer-than-driving/">the safest way to travel</a> – safer than cars, buses, trains or boats. But although aerospace engineers design aircraft that are stunningly sophisticated, you might be surprised to learn there are still some details about the physics of flight that we don’t fully understand. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/577439/original/file-20240222-28-v3tjb4.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/577439/original/file-20240222-28-v3tjb4.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/577439/original/file-20240222-28-v3tjb4.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=381&fit=crop&dpr=1 600w, https://images.theconversation.com/files/577439/original/file-20240222-28-v3tjb4.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=381&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/577439/original/file-20240222-28-v3tjb4.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=381&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/577439/original/file-20240222-28-v3tjb4.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=479&fit=crop&dpr=1 754w, https://images.theconversation.com/files/577439/original/file-20240222-28-v3tjb4.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=479&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/577439/original/file-20240222-28-v3tjb4.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=479&fit=crop&dpr=3 2262w" alt="A diagram of an airplane that shows the four forces of flight." /></a><figcaption>The forces of weight, thrust, drag and lift act on a plane to keep it aloft and moving. <a class="source" href="https://www1.grc.nasa.gov/beginners-guide-to-aeronautics/airplane-cruise-balanced-forces/">NASA</a></figcaption></figure> <h2>May the force(s) be with you</h2> There are <a href="https://www.nasa.gov/stem-content/four-forces-of-flight/#:%7E">four forces</a> that aerospace engineers consider when designing an airplane: weight, thrust, drag and lift. Engineers use these forces to help design the shape of the airplane, the size of the wings, and figure out how many passengers the airplane can carry. For example, when an airplane takes off, the thrust must be greater than the drag, and the lift must be greater than the weight. If you watch an airplane take off, you’ll see the wings change shape using flaps from the back of the wings. The flaps help make more lift, but they also make more drag, so a powerful engine is necessary to create more thrust. When the airplane is high enough and is cruising to your destination, lift needs to balance the weight, and the thrust needs to balance the drag. So the pilot pulls the flaps in and can set the engine to produce less power. That said, let’s define what force means. According to <a href="https://ca.pbslearningmedia.org/resource/4079abf0-7a4b-4f49-80ad-c69cd06a80f9/newtons-second-law-of-motion/">Newton’s Second Law</a>, a force is a mass multiplied by an acceleration, or F = ma. A force that everyone encounters every day is <a href="https://spaceplace.nasa.gov/what-is-gravity/en/#:%7E">the force of gravity</a>, which keeps us on the ground. When you get weighed at the doctor’s office, they’re actually measuring the amount of force that your body applies to the scale. When your weight is given in pounds, that is a measure of force. While an airplane is flying, gravity is pulling the airplane down. That force is the weight of the airplane. But its engines push the airplane forward because they create <a href="https://www1.grc.nasa.gov/beginners-guide-to-aeronautics/what-is-thrust/">a force called thrust</a>. The engines pull in air, which has mass, and quickly push that air out of the back of the engine – so there’s a mass multiplied by an acceleration. According to <a href="https://www.youtube.com/watch?v=a-wh3fJRdjo">Newton’s Third Law</a>, for every action there’s an equal and opposite reaction. When the air rushes out the back of the engines, there is a reaction force that pushes the airplane forward – that’s called thrust. As the airplane flies through the air, the shape of the airplane pushes air out of the way. Again, by Newton’s Third Law, this air pushes back, <a href="https://www1.grc.nasa.gov/beginners-guide-to-aeronautics/what-is-drag/#:%7E">which leads to drag</a>. You can experience something similar to drag when swimming. Paddle through a pool, and your arms and feet provide thrust. Stop paddling, and you will keep moving forward because you have mass, but you will slow down. The reason that you slow down is that the water is pushing back on you – that’s drag. <h2>Understanding lift</h2> <a href="https://www1.grc.nasa.gov/beginners-guide-to-aeronautics/what-is-lift/">Lift</a> is more complicated than the other forces of weight, thrust and drag. It’s created by the wings of an airplane, and the shape of the wing is critical; that shape is <a href="https://howthingsfly.si.edu/media/airfoil#:%7E">known as an airfoil</a>. Basically it means the top and bottom of the wing are curved, although the shapes of the curves can be different from each other. As air flows around the airfoil, <a href="https://www.youtube.com/watch?v=UO75jDwGCdQ">it creates pressure</a> – a force spread out over a large area. Lower pressure is created on the top of the airfoil compared to the pressure on the bottom. Or to look at it another way, air travels faster over the top of the airfoil than beneath. Understanding why the pressure and speeds are different on the top and the bottom is <a href="https://airandspace.si.edu/multimedia-gallery/lift-and-copjpg">critical to understand lift</a>. By improving our understanding of lift, engineers can design more fuel-efficient airplanes and give passengers more comfortable flights. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/579698/original/file-20240304-24-6df49v.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/579698/original/file-20240304-24-6df49v.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/579698/original/file-20240304-24-6df49v.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=385&fit=crop&dpr=1 600w, https://images.theconversation.com/files/579698/original/file-20240304-24-6df49v.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=385&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/579698/original/file-20240304-24-6df49v.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=385&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/579698/original/file-20240304-24-6df49v.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=484&fit=crop&dpr=1 754w, https://images.theconversation.com/files/579698/original/file-20240304-24-6df49v.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=484&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/579698/original/file-20240304-24-6df49v.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=484&fit=crop&dpr=3 2262w" alt="A diagram that shows how the airfoil of a plane works." /></a><figcaption>Note the airfoil, which is a specific wing shape that helps keep a plane in the air. <a class="source" href="https://www.gettyimages.com/detail/illustration/how-airplanes-fly-royalty-free-illustration/1401215523?phrase=airfoil+diagram&adppopup=true">Dimitrios Karamitros/iStock via Getty Images Plus</a></figcaption></figure> <h2>The conundrum</h2> The reason why air moves at different speeds around an airfoil remains mysterious, and <a href="https://www.scientificamerican.com/video/no-one-can-explain-why-planes-stay-in-the-air/">scientists are still investigating</a> this question. Aerospace engineers have measured these pressures on a wing in both wind tunnel experiments and during flight. We can create models of different wings to predict if they will fly well. We can also change lift by changing a wing’s shape to create airplanes that fly for long distances or fly very fast. Even though we still don’t fully know why lift happens, aerospace engineers work with mathematical equations that recreate the different speeds on the top and bottom of the airfoil. Those equations describe a process <a href="https://howthingsfly.si.edu/media/circulation-theory-lift">known as circulation</a>. Circulation provides aerospace engineers with a way to model what happens around a wing even if we do not completely understand why it happens. In other words, through the use of math and science, we are able to build airplanes that are safe and efficient, even if we don’t completely understand the process behind why it works. Ultimately, if aerospace engineers can figure out why the air flows at different speeds depending on which side of the wing it’s on, we can design airplanes that use less fuel and pollute less.  <a href="https://theconversation.com/profiles/craig-merrett-1509278">Craig Merrett</a>, Professor of Mechanical and Aerospace Engineering, <a href="https://theconversation.com/institutions/clarkson-university-4276">Clarkson University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

The one in-flight activity to avoid to conquer jet lag

While many people love to travel and explore new destinations, there’s no doubt that the worst part of a holiday is often the long-haul flight. With many holidays, especially ones overseas, a drastic change of timezones can mean jet lag is unavoidable, but there are a few things you can do to make life easy when you land. According to one travel expert, how you feel when you disembark often boils down to your in-flight activities. Sarah Built, who has worked up a lifetime of long-haul travel as the Etihad Airways Vice President of Sales for Australasia, told <a href="https://travel.nine.com.au/latest/flight-tips-how-to-avoid-jet-lag/db8fbda1-2318-44c0-b9fe-e14d11dec70c">9Travel</a> that there is one thing she always avoids onboard in order to land at her destination feeling fresh: alcohol. "Whilst the allure of coffee, cocktails and snacks is real (particularly if you're travelling with kids), they can actually contribute to dehydration and worsen jet lag," she says. Instead of that in-flight beer glass of wine, Sarah says to drink water (with lime added for a twist) or herbal tea to boost your hydration and lessen that groggy mid-flight feeling. Drinking water is obviously also the key to staying hydrated, as Sarah says it's important to start drinking extra water the day before your flight, so you're going in prepared. "I carry a reusable water bottle to keep fluids up during the journey (most airports will have water stations for you to refill easily)," she says, which means you won't need to pay for an overpriced bottle at the airport. "Dehydration can cause headaches and fatigue, and you want to be able to hit the ground running on arrival, so always remember to drink plenty of water," she advises. Image credits: Shutterstock

"Fly high, Bette!": World's longest-serving flight attendant dies aged 88

Bette Nash, the world's longest-serving flight attendant has passed away aged 88, after a short battle with breast cancer. American Airlines, where Nash devoted almost seven decades of her life, announced her death on social media on Saturday. "We mourn the passing of Bette Nash, who spent nearly seven decades warmly caring for our customers in the air," they began their post. “Bette was a legend at American and throughout the industry, inspiring generations of flight attendants. “Fly high, Bette. We’ll miss you.” A spokesperson for the airlines confirmed that she was still an active employee at the time of her death. Nash, who was born on December 31, 1935, began her flight-attendant career with Eastern Airlines in 1957, at just 21-years-old. In January 2022, she was officially recognised as the world’s longest-serving flight attendant by Guinness World Records, after surpassing the previous record a year earlier. She continued to hold the title until her passing. Tributes have poured in from people all over the world on social media, with many praising her for her unwavering dedication and kindness. "Fly high Bette! It was a pleasure being your passenger," wrote one person on X, alongside a selfie he took with her. <blockquote class="twitter-tweet"> Fly high Bette! It was a pleasure being your passenger. <a href="https://t.co/9N63YPB5Ia">pic.twitter.com/9N63YPB5Ia</a> — Jon Kruse (@JonKruseYacht) <a href="https://twitter.com/JonKruseYacht/status/1794459429997273423?ref_src=twsrc%5Etfw">May 25, 2024</a></blockquote> "She was flying as a passenger when she sat next to me, pinned her jacket to the bulkhead, gave me a three minute story of her life then said 'So what's your story?'. She was a dynamo. Rest easy," another added. "She was an absolute delight in my earliest airline life working the USAir shuttle at LGA. Godspeed and eternal silvered wings Bette!" a third wrote. <blockquote class="twitter-tweet"> She was an absolute delight in my earliest airline life working the USAir shuttle at LGA.

"Bette was a class act. Truly a loss for the skies. She was truly an Angel," added another. Image: CBS/ X

Flight attendant reveals what happens if a passenger dies onboard

A flight attendant has revealed what happens if a passenger dies onboard, and the morbid reason the protocol has changed in recent years. Mandy Smith has been a flight attendant for 12 years and thankfully, hasn’t had to encounter such a tragedy during one of her flights. According to the protocol of the airline she serves, previously when passengers passed away on board they used to be put inside the bathrooms, but now their bodies are laid across the front seats. She explained to LadBible, “This has not happened to me, thankfully. It happened to a friend of mine, where they had a passenger pass away on the flight.” “Now, we used to have to put passengers in the bathrooms, and then lock the bathrooms off. But because they would be seated on the toilet, as they sat there - if rigour mortis set in - then they would be then stuck in that position, and they wouldn't be able to fit in their coffin.” 'So, unfortunately, now, we have to lay them across the front of the seats and try and calm their loved ones down, treat them with respect, cover them with blankets, and maybe just cordon the area off with blankets tucked into the overheads, which is what I would probably do.' Mandy also explained that according to different laws, if someone dies on a flight, cabin crew officially have to keep going to their final destination. She said, “If they passed away on board, it's the law that we, as cabin crew, have to keep going. So, we have to keep doing any kind of resuscitation until they're deemed to be deceased.” “So, if it was an accident that happened on board, or if they had a heart attack, we would then just keep going doing CPR.” “But if it was someone who passed away from natural causes, or another kind of ailment, then obviously, we wouldn't need to do anything to them then.” “We'd need to contact the ground services to be met by an ambulance or the coroner. We wouldn't really do it as an emergency landing, we'd just treat it as a normal landing if that person's definitely passed away.” Image credits: YouTube
