However, a new travel hack making the rounds may tip the scale in favour of choosing the aisle seat.
According to The Independent, a little button hidden under the armrest is the key to having more space while flying.
"The 'secret' button, which isn't flagged up by airlines and few people know about, allows you to lift the armrest on the aisle," the publication writes.
"To find it, feel under the armrest - you'll find a button close to the hinge. That releases the armrest and allows you to move it up so it is flush with the back of your seat. That gets you a little more legroom, a lot more wiggle room, and space to spill out into the aisle (just watch for the trolley when it comes your way)."
