Cabin Crew are used to working in a high-pressure environment and, on a regular basis, witness the strange, unhygienic, and sometimes even dangerous behavior of passengers. From passenger meltdowns to unusual ’emotional support animals’ and strange requests, almost every cabin crew member has an obscure story about the bizarre things they have seen onboard the aircraft. In this guide, we will take a look at a few of the more unusual events that have been reported in the skies.

One thing that most crew agree on is that Passengers change immediately once they step inside an aircraft. We often say that they must have packed their brains in their hold luggage, as some behaviors, once seen, you can not quite believe. Whether it’s caused by the stress of flying, anxiety, or moments of madness, cabin crew rarely have a dull day (or night) ahead of them. Let’s take a look in more detail.

Dangerous Behavior

Passengers often break rules and disobey the crew’s instructions, even if it’s a life-threatening situation, for example, taking bags when evacuating an aircraft. If there is a fire onboard, and you need to leave immediately, why waste time getting your bags when it risks your or someone else’s life? Passengers sometimes try to smoke or vape in the lavatories, although it is an offense to do so. Tampering with smoke detectors and alarms is illegal, and although it’s obvious to the crew, passengers deny that it was them. One hot cigarette in a waste bin of paper towels can easily start a fire, not something we want at 30,000 feet.

Intoxicated passengers are a recurring issue, and cabin crew can refuse them to board the aircraft. Also, anyone who acts entitled or aggressive is on the radar for removal from the aircraft. We do not want issues onboard during the flight that threaten the Safety of the aircraft, passengers, and crew. This can also lead to passengers being restrained, the aircraft being diverted, and being met by security, as well as fines and possibly imprisonment.

Disruptive and unruly passengers are increasingly common, and most ‘events’ involve alcohol and passengers picking a fight with another passenger. The cabin crew has to try to de-escalate the event and find a solution. Other cases include passengers trying to open exit doors during the flight, opening an exit on the ground, or trying to gain access to the flight deck. These kinds of events can be due to intoxication, medication, or psychological issues.

Strange Odors

Of course, in a metal tube in the sky, there will be odors. The first cabin crew notice on entering the aircraft is the unmistakable mix of airline food, lavatories, and socks, often referred to as ‘Eau de Boeing’. During the flight, there is always the smell of the lavatories and passenger odor. It is always important for passengers to be hygienic prior to their flight, and it is advised not to walk to the lavatories in socks or bare feet; that is not water on the floor. Coffee bags are sometimes placed near the galley to prevent such smells.

Passengers also often lose their sense of awareness when onboard the aircraft and may attend to matters that would normally only be practiced behind a bathroom door. There is no place for personal hygiene matters in an aircraft cabin or exposing behavior in such a small space to other passengers. Cabin crew are often asked about the ‘mile high club’, but in reality, lavatories are tiny, full of bacteria, and smell bad. Why would anyone want to do that? The lavatories are always busy, next to a galley, and are checked every twenty minutes.

Also, on the subject of odors, surely it would be common sense not to eat strong-smelling food like tuna or egg sandwiches on an aircraft? On a regular basis, cabin crew see infants’ diapers being changed on tray tables, empty seats, and even on crew seats. Afterward, the diaper is handed over to the crew in a waste bag, often during the service, which is not acceptable. Sometimes, passengers seem completely unaware that this kind of thing is wrong.

Passenger Problems

During long flights, passengers often congregate near the galley and exercise before or after using the lavatory. Cabin crew are happy to get you a drink or a snack or have a quick chat, but we work in a small space with lots of hot surfaces and heavy equipment. It is good to stretch your legs, but exercise is not good. Exercising in our space is not a good idea because it can lead to injury and also intrudes on our very limited personal space.

Personal space on an aircraft should always be respected, and the passenger in the middle seat should always have access to both armrests. Children should be supervised and not allowed to kick the seat in front of them. One of passengers’ most common gripes about other passengers is being sick and spreading disease, according to posters on Reddit. The other is bad hygiene standards and behavior associated with them.

One flight attendant describes on YouTube how he deals with emotional passengers and is seen as a therapist, as well as a cook and a cleaner. He said he’d heard about breakups and toxic relationships more times than he can remember, and overly emotional passengers often end up crying on his shoulder or needing a hug. Some flight attendants have witnessed passengers removing clothing during the flight and have to assist with a blanket.

Emotional Meltdowns

One passenger boarded a flight and immediately asked the cabin crew for an upgrade, and the cabin crew apologized and explained that it was not possible. The woman then asked her for a glass of water and again for an upgrade, to which she said, “No, sorry.” The woman then took a tablet and gave a story that she should be upgraded because she’d been in a plane crash. She acted irrationally and was causing a scene, so she was offloaded by the senior crew member.

In 2025, a passenger was caught vaping in the lavatory, and the flight attendant opened the lavatory door, apologized, and said that vaping was a hazard, and that he must stop, and that she was looking after her passengers. He tried to film her, and she tried to grab his phone. He then accused her of assaulting him. He threatened her with lawyers, claimed he was a lawyer, and then said he had 25,000 followers on Instagram. He was removed from the flight and posted the video on Instagram. He later apologized but still threatened to sue the airline and has yet to be convicted.

Again in 2025, a woman on a flight to Texas had a breakdown before leaving the gate. She was making a scene in the cabin, saying that she needed to talk to her mother and that her son needed to be picked up from school. Security was brought on board, and she grew increasingly agitated and started shouting and cursing. She was removed from the aircraft. It turned out that she had been removed from a flight the previous day, also and she was put on the ‘No Fly’ list.

The Bizarre

One flight attendant reported that her aircraft had to go back to the gate, as there was an unregistered minor onboard and her mother had been offloaded during boarding for being intoxicated. The parent seemed to forget she had a daughter on board the aircraft, and the minor said nothing. Upon landing on her first flight, one flight attendant was surprised to see the aircraft met by a team of police. The passengers were told to remain seated, the aircraft was stormed, and the police arrested a man convicted of armed robbery and dragged him off the aircraft.

Another flight attendant stopped a passenger from boarding with an emotional support animal. She said they did not allow squirrels on board, but the man looked at her directly and said that it was a cat. She and her colleague examined the creature again and then offloaded the passenger and his squirrel. She told Travel and Leisure that for a moment she questioned her own sanity, wondering why did a cat have a squirrel’s tail?

On the twoguysonaplane podcast, one flight attendant described how he checked on a passenger with an infant, but saw no visible signs of the infant or any blankets or toys. He asked her if she had an infant, and she said yes. He asked her where the baby was, and she said in the overhead locker. She’d followed the instruction that carry-on items must be placed in the overhead locker or under the seat in front of you. She didn’t want to put the baby she’d carried on on the floor, so she put her in the overhead locker instead with her blankets and toys. She was a first-time traveler and took instructions a little too precisely.

In Conclusion

Passengers often display unusual behavior onboard. These are mostly due to intoxication, but can also be from psychological problems. These can mean a drunk passenger may cause an argument or pick a fight with another passenger or crew member. Some attempts have been made to operate emergency exits, although this cannot happen at 30,000 feet because of the air pressure, although they can be opened on the ground and may blow a slide if armed.

Cabin crew will try to spot problems before they start and be extra attentive during boarding and prior to takeoff to stop any potential disruptive passengers from boarding. Sometimes crazy experiences happen during a flight, but they’re often caused by inexperienced flyers (trying to open the emergency exit thinking it’s the lavatory door is one example) or by fear of flying, which can turn into full-blown panic and may be disconcerting. In this case, a passenger may be taken to a quieter area of the aircraft to de-escalate the situation.

Passengers do the strangest things, but luckily, cabin crew are trained to deal with unruly passengers and strange behavior. They have a strong sense of situational awareness, which helps when the odd happens and must be dealt with immediately. Cabin crew are always the calm in the chaos, and every day is different and unpredictable. They are always ready to deal with the unexpected, and there will always be another ‘wild’ situation to tackle onboard; the crew take it in their stride.
