A Delta Passenger Was Horrified by What a Grown Man Was Doing Right Beside Them on a Flight. Then People Started Demanding That Airlines Take Action

I love traveling, but I sincerely hope I never experience certain situations. No matter how carefully we plan a trip, some things are simply beyond our control, especially when we’re sharing a relatively small space with complete strangers.

I’ve written about a Delta passenger’s disgusting armrest discovery, someone who decided to paint her nails during a flight, and even a personal grooming habit that horrified passengers and flight attendants alike. In other cases, something as seemingly harmless as opening a window shade has led to disagreements.

I usually try to give people the benefit of the doubt. Someone might be exhausted, uncomfortable, distracted, or dealing with circumstances we know nothing about. I’ve had unpleasant travel experiences myself, and I understand that we don’t always have the luxury of changing our plans when something unexpected happens.

But a recent Delta passenger described what a grown man was doing right beside them, and I found the account revolting. I learned that flight attendants have complained about similar behavior for months, while passengers shared stories of missed work, ruined trips, and even a first-class flight that took an unexpectedly unpleasant turn. What surprised me was how divided people were – and I am sharing all the perspectives with you.

A Delta Passenger Was Disgusted by What the Man Beside Them Was Doing

On October 14, 2026, a traveler posted a complaint in the Delta community on Reddit, asking why so many passengers seemed unwilling to take even basic precautions when they had respiratory symptoms.

During a recent flight, the passenger sat next to an adult man who was doing something most people would prefer not to witness, especially while eating, drinking, or touching the same surfaces.

“I sat next to a guy who had to be at least 25 who was actively wiping his snot in his hand and touching everything…”

According to the traveler, the man wasn’t the only person causing concern. They estimated that at least ten other passengers were coughing throughout the flight without covering their mouths.

The post ended with a question:

“What is going on with basic hygiene?”

Imagine sitting next to someone who repeatedly wipes mucus from his nose onto his bare hand and then touches the armrest, seat belt buckle, or other surfaces around you. Even if he wasn’t contagious, I’d find that difficult to ignore. The complaint sparked strong reactions, including from people who felt travelers had become less considerate of those around them. I’m sharing these reactions below in the article.

The concern isn’t limited to whether someone gets sick. Passengers also have to consider what previous travelers may have left behind, as I’ve covered in my article about the filthiest parts of an airplane.

But the Delta passenger’s complaint reminded me of another Reddit discussion I found, this time involving flight attendants. Some of the behaviors they described were even more revolting.

Flight Attendants Say They’ve Had Enough – and the Details Are Revolting

In January 2026, someone posting in the flight attendants’ Reddit community expressed their frustration with passengers who cough openly, sneeze without covering their mouths, and leave used tissues behind.

The person didn’t attempt to hide their anger.

“Wear a fucking mask or better yet, stay home!!!!”

They went on to describe what had apparently become a recurring source of disgust during their work: open-mouth coughing, sneezing into the air, and mucus-covered tissues scattered across tray tables.

Yes, the same tray tables where other passengers put their food and drinks.

I’ve previously shared flight attendants’ biggest passenger red flags, including accounts of crew members being expected to handle dirty diapers, used chewing gum, and vomit bags with their bare hands. Apparently, tissues covered in mucus belong on that list as well. I also shared the oddest things passengers asked flight attendants – some are truly unbelievable!

In the January discussion, someone agreed with the criticism but argued that passengers weren’t the only problem.

“Agree about the passengers but also the FA’s.”

The commenter explained that on a flight home from Dallas/Fort Worth, a flight attendant had appeared extremely unwell and coughed throughout the journey without wearing a mask. The traveler felt bad for her but was also annoyed.

The original poster acknowledged the complaint, saying they were frustrated when crew members came to work sick without taking precautions. They also recognized that not every employee could afford to call in sick.

Another participant mentioned probationary flight attendants, suggesting some employees might be reluctant to miss work because they worry about their employment.

One Passenger Reportedly Knew He Had a Bad Cold – and Sat Next to the Flight Attendant Anyway

Another commenter described an encounter with an older man who boarded a flight and asked whether it was full.

When told that nearly all the seats were occupied, the man reportedly admitted that he had a bad cold and didn’t want to infect anyone. Then he sat directly beside the flight attendant’s jumpseat without wearing a mask. The flight attendant shared the man’s reported words:

“I have a pretty bad cold I’d hate to get someone sick”

His concern about potentially making someone else ill seemed genuine enough to mention, yet the commenter described no attempt to take extra precautions.

Other people in the discussion shared contrasting experiences. One traveler said they developed influenza A during a business trip and drove home instead of flying, even though it meant changing their travel arrangements.

Another person said they always carried a mask after repeatedly encountering travelers who appeared ill.

Several commenters noted that flight attendants encounter hundreds of passengers during a shift. Unlike travelers who leave the aircraft after reaching their destination, crew members may have to deal with the same behaviors repeatedly during a working day.

Passengers responding to a separate Delta discussion shared plenty of firsthand experiences.

Other Delta Passengers Shared Their Own Experiences – Including One Who Missed 15 Days of Work

In the October Delta discussion, one traveler described a previous flight from Cleveland to Pensacola, Florida, during which the person sitting beside them coughed continuously without covering his mouth.

The commenter subsequently became ill with influenza A and said they missed 15 days of work.

“Last time I flew (on a Delta flight coincidentally) I sat next to a guy from Cleveland to Pensacola (FL) who was coughing the entire time.”

The account continued with a disturbing description of the days that followed. The traveler said they became so ill that they struggled to remember getting home from work. Later, while a roommate, who was also sick, drove them to the hospital, the vehicle reportedly struck a tree.

The commenter said they were hospitalized for several days and that their roommate was also admitted for observation.

There is no way to verify whether the traveler contracted the illness from the coughing passenger. But the experience had clearly stayed with the traveler, who ended their comment by urging people to practice better hygiene and keep emergency contact information updated.

Another passenger reported a similar concern:

“I got bronchitis from someone hacking up a lung.”

That person said they now wear a mask on flights during fall and winter because of previous experiences.

Others reported that wearing masks had become a permanent part of their travel routine.

“I’ve never stopped wearing one on planes and trains. It’s vital.”

Another traveler said they had adopted the same habit after the pandemic, particularly in airports, crowded queues, and other places where they might be close to many people.

“Haven’t gotten sick from a flight, AFAIK, since 2019.”

Not everybody found wearing a mask entirely hassle-free. One person complained that strangers sometimes asked whether they were sick simply because they were wearing one.

The commenter said they wore a mask because getting ill during a trip was unpleasant, yet other travelers occasionally interpreted the precaution as evidence of an infection.

Someone who identified as immunocompromised responded appreciatively, saying seeing others wear masks was reassuring.

Another traveler described an even more hostile reaction, alleging that people had deliberately pretended to cough near them after noticing their mask.

Some people also rejected the idea that they should have to worry constantly about what strangers were doing.

“Will I lose sleep over others who I cannot control? No.”

That commenter said they would personally wear a mask if they were ill but saw little benefit in becoming angry about the behavior of people they couldn’t influence.

For travelers concerned about having the right supplies, masks, wipes, and hand sanitizer are easy to include among the essentials in a carry-on bag. They can be forgotten, though, especially when preparing for an early departure. My night-before-flight checklist covers the other preparations worth making before departure.

One American Airlines passenger admitted they regretted not having a mask after an exciting upgrade turned into a thoroughly unpleasant journey.

An American Airlines Passenger Was Excited About a First-Class Upgrade. Then Someone Started Vomiting

In January 2026, a traveler shared an account of an American Airlines flight from Columbia, Missouri, to Dallas/Fort Worth. The passenger had received an upgrade to first class, something most travelers would happily accept. But once onboard, they discovered the premium cabin was occupied by a family whose members appeared ill.

According to the post, the family members were coughing repeatedly without covering their mouths or wearing masks. The traveler described the supposedly fortunate seating assignment as:

“a cursed upgrade.”

The passenger was furious, saying the entire first-class cabin seemed exposed to the family’s coughing. Then the situation reportedly deteriorated.

The Passenger Posted an Update From the Flight

What began as a complaint about coughing worsened when someone reportedly started vomiting during the journey.

“Edit: so much worse in-flight. It turned into puking as well.”

The traveler regretted not bringing a mask and said they intended to buy one immediately after reaching Dallas/Fort Worth, where they had a connecting flight.

Other Reddit users shared their own precautions, including keeping an N95 mask in a backpack or pocket. Some said they had become so accustomed to encountering coughing passengers that they never boarded without one.

“An N95 takes up almost no space and is worth carrying for these situations.”

One person suggested airlines offer complimentary masks, while others discussed ventilation and using the adjustable air vents above passengers’ seats.

The discussion didn’t establish what caused the family’s symptoms or the vomiting. Motion sickness, for instance, can also cause vomiting, and the traveler had no way of diagnosing the family members.

But the unexpected developments were enough to spoil what should have been a more comfortable journey. And another Delta traveler described a very different consequence after three long-haul flights.

A Delta One Passenger Said They Missed an Entire Conference After Becoming Ill

In February 2026, a traveler who had taken three long-haul flights in Delta One over two months asked whether other passengers were noticing a similar pattern of illness after flying.

The person said they had developed a cold or similar symptoms following each flight. One episode reportedly ruined an entire business trip.

“In one case, I was so sick I missed an entire conference and never left my hotel room.”

The passenger criticized what they saw as declining cleanliness and hygiene standards, saying airport lounges and aircraft were overcrowded and people seemed to be coughing everywhere.

Missing a conference after a long trip can mean more than disappointment. Depending on the trip’s purpose, you may face registration fees, accommodation costs, missed meetings, and professional opportunities you can’t recover.

Even careful accommodation choices don’t protect you from every problem during a trip. I have an extensive guide on what to check before booking a hotel, plus a five-second hotel room check I recommend after arrival. But no hotel booking checklist can prevent illness or keep you from missing the very reason for traveling.

The Delta One passenger’s post drew mixed reactions, including from people who said they got sick less often after changing their travel habits.

One person explained that they now wear a mask even on flights lasting just 30 minutes, after hearing about a friend’s experiences traveling frequently for business.

Another commenter argued that airports might present more opportunities for exposure than the aircraft themselves, given the time travelers spend in terminals and queues.

But there were also passengers who said they continued becoming ill despite their precautions.

“I wear a mask and still get sick every time 🫠”

That traveler added that they also wiped down the tray table, seat, seat belt buckle, and their hands.

Others mentioned the airplane’s ventilation system and encouraged passengers to turn on the adjustable overhead air vents.

The accounts cannot establish whether any particular illness was acquired onboard an aircraft, in an airport, at a hotel, or elsewhere during a journey. Nor do personal accounts show whether a specific precaution worked or failed. Still, the comments revealed how many frequent travelers were frustrated by their experiences, especially when illness disrupted work, family visits or long-planned vacations.

Some Travelers Were Furious About the Criticism – Because They Couldn’t Afford to Cancel Their Flights

While many commenters condemned people who travel when they’re sick, others argued that the situation was far more complicated than simply deciding to stay home.

One person responding to the flight attendant discussion described becoming ill during a trip to Paris.

They said they couldn’t afford to extend their stay for another week or wait until they had completely recovered. Instead, they returned home on their scheduled flight while wearing a mask.

“I couldn’t delay and stay in Paris another week or until I got better. That was out of my budget by a lot.”

The commenter acknowledged that wearing a mask while feeling unwell was uncomfortable but said they continued wearing it throughout the flight.

Another traveler described being sick while accompanying their brother to college. They reportedly took medication, wore a mask and covered up during the journey because they didn’t want to lose approximately $400 or miss an important family occasion.

Someone else asked a pointed question about the financial implications:

“Would you just throw away a grand because you are a little sick?”

Other commenters mentioned funerals, business meetings that couldn’t be postponed, and family emergencies.

In the October Delta discussion, a traveler explained why people returning from international trips might have few realistic alternatives.

“Some folks can’t afford to change a ticket, spend several more days abroad, etc.”

Another participant described a friend who had to travel to China to complete arrangements for adopting her daughter. According to the commenter, the journey involved a scheduled court date and a required period in the country, making postponement exceptionally difficult.

These examples prompted disagreement about whether someone with respiratory symptoms was automatically behaving irresponsibly by boarding an aircraft.

One person in the flight attendant discussion argued that people were overlooking the distinction between unavoidable travel and behavior that needlessly exposed others.

“The selfish part is not traveling while sick, the selfish part is refusing to take measures to protect the people around you while you’re sick.”

Not everyone agreed with that position. Some commenters insisted that traveling while infectious was unacceptable regardless of the circumstances, especially because vulnerable people might be sitting nearby or passengers might be visiting elderly relatives.

Others pointed out that a cough can be caused by allergies, asthma or another noninfectious condition, and that fellow passengers have no way to determine someone’s medical condition from their appearance.

The arguments then turned to the airlines themselves.

Some Commenters Blamed the Airlines – and Wanted Different Rules

Several people believed airlines contributed to the problem by making illness-related changes too expensive or inconvenient.

In the original Delta discussion, one participant argued that travelers respond to the financial consequences of canceling a flight. If missing a departure means paying hundreds or thousands of dollars, some passengers will travel despite feeling unwell.

“If you don’t want sick people on planes, take it up with Delta.”

The same commenter suggested that airlines could offer more flexible illness-related rebooking, provide masks and communicate more clearly about cabin air quality.

Another traveler wanted airlines to enforce precautions when they witnessed passengers coughing or sneezing openly.

“I wish airlines enforced masks when witnessing active sneezing/coughing, stock cleaning wipes in every seat, or offer immediate rebooking at no cost.”

In the flight attendant discussion, a commenter proposed allowing travelers a limited number of illness-related flight changes without paying the difference between the original fare and the replacement ticket.

Others were skeptical that such arrangements could be implemented fairly, while some objected to airlines or crew members deciding whether passengers should be required to wear masks.

The disagreement extended to whether people should be screened for symptoms before boarding and whether airlines should provide protective equipment.

These were proposals from Reddit commenters, not announcements of new Delta or American Airlines policies.

Other Travelers Said Masks Weren’t a Complete Solution – and Some Refused Them Altogether

One recurring argument in the discussions concerned masks, including whether they offered sufficient protection when someone was sitting next to a coughing passenger for several hours.

Some people said they wore N95 or KN95 masks on every flight. Others preferred simply using hand sanitizer, disinfectant wipes or the overhead air vent.

A few questioned whether wearing a mask made much difference during a prolonged flight.

“I agree but do you really think a mask does anything on a plane where you are sitting for hours next to a sick person?”

Another commenter argued that masks were uncomfortable for people with significant nasal symptoms, although they agreed that covering coughs and sneezes should be standard practice.

Medical guidance is more specific than some of these comments suggest. The CDC recommends well-fitting masks as one of several measures that can help reduce respiratory virus transmission. High-quality, properly fitted respirators such as N95s offer greater protection than loose-fitting face coverings.

Commercial aircraft also have ventilation and filtration systems that help reduce airborne exposure, although they don’t eliminate the possibility of transmission between people sitting close together.

Disagreements over masks have occasionally led to confrontations, including one that reportedly cost a United Airlines passenger the seat they had originally paid for.

A United Passenger Offered a Mask to a Coughing Seatmate – and Reportedly Ended Up in a Worse Seat

In March 2025, a United Airlines passenger described sitting beside a woman who appeared unwell, coughing and sneezing repeatedly.

The traveler said they offered her a mask, but the suggestion reportedly made her angry. According to the Reddit account, she summoned a flight attendant, and the person who offered the mask was subsequently moved from Economy Plus to a less desirable middle seat near the toilets.

The incident drew substantial attention, including coverage by Travel + Leisure, and sparked debate over whether offering a stranger a mask was considerate or potentially offensive.

Some people felt the passenger was unfairly penalized, while others argued it was better to ask a flight attendant for help than to approach a seatmate about their health.

In another Delta discussion from December 2024, a passenger described sitting near a couple who reportedly acknowledged being ill. According to that account, both refused masks the traveler offered.

In July 2025, a separate Delta passenger complained about a group returning from a cruise who repeatedly coughed on a flight from Greece. The post alleged that the travelers refused masks even after crew members intervened.

I’ve covered plenty of conflicts involving passengers and airline staff, and these accounts show how quickly an apparently well-intentioned interaction can become contentious.

The United incident has already received media coverage, while the older Delta stories remain firsthand online reports. No one has independently verified the full circumstances.

Conclusion: How Would You React if This Happened Beside You?

Returning to the original October Delta discussion, I still find the man’s reported behavior hard to understand. Watching someone wipe mucus onto their bare hand and then touch shared surfaces would be unpleasant under almost any circumstances.

But the additional accounts sparked a much broader debate: passengers describing serious illnesses after traveling, flight attendants criticizing hygiene practices, and others explaining why canceling a trip may be financially or personally impossible.

Some people want airlines to intervene more often, while others don’t believe strangers or crew members should make judgments about someone else’s health.

I’m curious what you would have done if you were sitting beside the man described in the original Delta post. Would you have said something, asked a flight attendant for help or simply avoided touching anything around you?

And what do you think airlines should do when someone appears to be ill? Should rebooking be easier, should masks be offered to passengers, or should everyone be responsible for their own precautions?

Editor’s note: The incidents described in this article are based on firsthand Reddit accounts and comments. Their complete circumstances, medical claims and reported outcomes have not been independently verified. Becoming ill after a flight does not establish where or from whom an infection was contracted.
