We all have annoying habits, and travel tends to bring out the worst in people.
If you have any sympathy for your flight attendants (who, day in and day out, are privy to some of the most extreme human behavior), you should make an effort to avoid these.
The first step is knowing just what you’re doing wrong.
Luckily for you, we asked flight attendants everywhere to share the annoying things they wish passengers would stop doing, and more than 60 were happy to chime in.
Here are 21 things you may not have even known you were doing wrong on your flight:
Don’t take up too much space in the overhead bins.
“Put the suitcases in the overhead and put your small bags underneath the seat in front so we don’t have to run out of space and have to check bags.”
Flight attendants wish more passengers said hello.
“I wish passengers would acknowledge the crew when they board.”
Wait until the flight attendant comes around with a trash bag to give him your garbage.
“Stop trying to hand us trash on the beverage cart or asking us to take your trash while we’re handing out food.”
Stop putting feet on walls or other passengers’ seats.
“I don’t come into your office and put my feet on your walls or your desk!”
Don’t ask your flight attendant “what do you have?” when she comes around with the beverage cart.
“There is literally an announcement telling you where to find the menu. We have 100 drinks if you count alcohol, and you want me to list it? While 200 other people wait for their drinks?”
Listen to the safety presentation.
“Be a little more respectful of crew while we are just trying to do our job.”
Tell your flight attendant exactly how you take your coffee.
“When you order coffee, tell me whether you want cream and/or sugar so I don’t have to ask for the millionth time.”
Take some responsibility for your belongings.
“Don’t bring your heavy carry-on on board the aircraft and then ask me to put it in the overhead bin for you because it is too heavy for you to do it.”
Flight attendants do not want you to occupy the toilets once you see that the aircraft is descending.
“This leads to flight delays.”
Take your headphones off when your flight attendant is talking to you.
“Please take the headphones off when we come by and ask you what you would like to drink.”
Only ring the call button when it’s truly necessary.
“Don’t ring call bells when we’ve already announced that flight attendants have to be seated, right after takeoff, or for silly reasons.”
Flight attendants prefer you keep your hands to yourself if you need their attention.
“I have been poked, prodded, and tugged on too many times to remember.”
Don’t get up to use the lavatory when the seat belt sign is on.
“When you remind them that the sign is on, they usually respond with some version of ‘But I have to go.’ Well, unless you are 2 years old, do you wait until the absolute last minute to use the toilet?”
Avoid thinking the world is coming to an end because you didn’t get your first meal choice.
“It’s a plane ride, not a five-star hotel or restaurant. Stop getting bent out of shape over receiving your second meal choice.”
Don’t act like you’re entitled to first-class seats.
“Stop trying to sneak into an upgrade seat.”
Flight attendants beg you to keep your shoes on.
“Please, please, please — stop walking into the restroom barefoot, or even with socks on. Would you ever walk into a public restroom barefoot? No. Thank you, sir, for mopping up the pee on the floor with your socks.”
Try to bring your own pen.
“Don’t ask me for my pen. Bring your own. It’s hard to believe someone travels around the world with no pen.
Avoid snapping your fingers to get your flight attendant’s attention.
“‘Excuse me, miss!’ works every time.”
Don’t chaturanga in the galleys.
“Getting up and wanting to stretch in our galleys like its a yoga studio or wanting to stand in our galleys is annoying. The galley is our only work area, and we have nowhere else to go because our seats are in the galley by the doors.”
There’s no need to get upset with flight attendants for things that clearly aren’t their fault.
“I agree it sucks that the flight got canceled and you’ll miss something important. I was supposed to go home and see a concert. Now I’m stuck in this small metal tube with you yelling at me.”
Flight attendants rarely have all the information from the captain — so don’t ask them for it.
“We know maybe 5% of what they do. We don’t know how bad the weather is, why we are taking a new route, or why we can’t land early. But believe it’s for your safety!”
