How to travel when flying on a plane
Determine whether you need just a carry-on item or if you also need a checked bag.
Depending on how long you will be traveling or what types of items you are packing, figure out what types of luggage you need to use.
The permitted size of carry-on bags varies from airline to airline.
Check the requirements for the airline with which you will travel to learn how big your carry-on bag can be. Remember that certain items are only permissible when packed in a checked bag.
