International carry-on luggage is very similar to standard carry-on bags; however, the sizing and dimensions are often slightly different. International carry-on luggage allows passengers to bring their items along on a flight without having to check a bag. International carry-on luggage is smaller than most standard carry-on sizes as they are meant to fit the cabin of smaller European planes and private jets. Also, for extremely long trips, many passengers will choose to bring a carry-on bag as well as checked bags. The checked bags allow you to carry enough gear for a long journey, but utilizing a carry-on bag means that you don’t have to worry about being without a change of clothes or needed medication if the luggage is delayed.
