If you need to move another passenger’s belongings, ask before you do so. You don’t know what some people may consider a violation of privacy. To avoid conflict simply ask if it’s ok to move their bag to make room for yours.

There are size restrictions for a reason. Watching someone try to squeeze a bag in the overhead compartment that is too big is frustrating and can delay the boarding process as the bag may have to be removed from the cabin and stowed away with checked-in luggage. So make sure your checked-in luggage meets the recommended measurements to ensure you’re not the most hated person onboard.

If you see a duffel bag in the overhead bin, don’t place your hard shell suitcase on top of it. Either ask the owner of the duffel bag if it’s ok for you to place your luggage underneath it or just store your bag next to it. If you see other soft items, like a sun hat (refer to next point), the same rule applies.

Jackets, hats, coats, pillows, anything that isn’t a carry-on suitcase should be placed in the overhead compartment last and only if there’s room. Don’t take up precious storage space on items that can fit under the seat or placed on your lap.

Flight attendants have enough to do when boarding a flight. They are not your personal porter. Your bag is your responsibility. Unless, of course, there is a medical reason you’re unable to do it yourself.

Most domestic flights in Australia have a weight limit of 7kg, which ensures bags are easy to lift and if they fall on someone won’t cause too much pain. International flights allow more, some airlines don’t have any weight restrictions with carry-on, but passengers need to be able to lift and remove the bag from overhead bins on their own.

Tote bags that can’t be closed should go under the seat in front of you or there should be no loose items that can escape from the bag when the plane takes off. Otherwise, you’re going to hear the sound of said items tumbling out of your bag as it tips over on take off. If you can wedge it between two suitcases so it doesn’t fall, great. If your items do fall out, wait till fellow passengers have removed their bags from the compartment so you’re not holding everyone up when retrieving your goods.

Ideally, the closer the better. If the overhead bin above you is full when you board, then you may have to ask a flight attendant where to find a spare spot for it. Wait till most passengers are off the plane before collecting your bag. Trying to navigate your way down the plane aisle while people are trying to disembark will not only see you invading people’s personal space, but it will not make you popular.

Before sitting down do a quick dummy close of the lid to see if your carry-on luggage is blocking the lid from closing. If it is, give your bag a shuffle and make it fit. Don’t leave it for the flight attendant to do when doing a final sweep of the cabin.

Basic kindness, people. If you see someone elderly or pregnant person and they’re struggling to lift their bag then offer them a hand.
