A man has been slammed online after he decided to move someone else's hand luggage on a jam-packed flight.
The man was boarding a fully booked flight when he was trying to find a spot to put his onboard luggage in the overhead containers.
Seeing there was a backpack and a coat inside the overhead lockers, he took it upon himself to move the backpack to the seat below - after asking whose bag it was, to no response.
When the owner of the backpack returned, he was enraged by the man's actions and stormed off - which took him by surprise.
He claims that the overhead lockers are just for people who paid extra and those with small hand luggage should put it underneath the seat below.
Writing on Reddit, the anonymous flyer said: "Packed low-cost flight (Ryanair UK), overhead lockers are typically reserved for hand luggage and the flight attendants tend to mention that backpacks should go under seats, although they don't enforce it.
"The flight is very busy during boarding, many people waiting behind me while I try to find a spot on the overhead lockers full of backpacks, coats, and all kind of stuff that should go under your seat.
"I look for a flight attendant around to help place my hand luggage in a non-existent free spot but there's noone around apart from other impatient passengers.
"I take a random backpack and ask to the people nearby 'whose backpack is this' and no-one answers.
"So I take that backpack, place it under the empty seat next to mine, and hoist my hand luggage in the overhead storage.
"At the end of the flight I put that stranger's backpack on the seat and wait for the owner to come look for it."
The man continued: "When he comes back (turns out he was elsewhere on the plane, that's why he could not hear me when I asked around) I point out that I had to make space for my luggage, and he got very upset.
"I point out that backpacks should go anyways under the seat for this very reason (Saying 'it's kind of a rule, ask the attendants'). But he wouldn't take it and just stormed out super angry and what-not.
"This lack of space happens fairly regularly due to everyone just putting all sort of random stuff and small bags in the overhead locks - but I seem to be the only person annoyed by that."
However, many readers of the post were alarmed at the man's actions and criticised him for moving someone else's property without permission.
One Reddit user wrote: "I love how you've just made up this 'rule' of travelling and seem upset that A) no one seems to have heard of this and B) dare to mess with other people's bags due to your self-imposed rule.
"This is arrogant and very poor travel etiquette.
"Feel free to slide bags sideways or even rotate them in the overhead bins to get things to fit Tetris-style, but you do not move bags from over bins and certainly do not relocate bags."
Another said: "You should have waited for a flight attendant."
And a third added: "You don't move others belongings without their knowledge or consent. You should have called over an attendant or put your bag into the empty seat beside you until one came and questioned."
A fourth said: "He might have paid for the overhead luggage, which gives him the right to store it there. That aside, you have no right to put your hands on other peoples property."
One commented: "How entitled do you have to be as a person to move someone else's luggage."
