If you anticipate carrying on your bag or assessing it, it's crucial that you remember that every airline has their own requirements. By way of example, Air France has a carry-on dimension limitation of 21 x 13 x 9 inches, where as Southwest restricts their carry ons to 24 x 16 x 10. You might want to choose your custom made luggage bags based on the lowest, if different airlines soar normally found dimensions so you will fit more air companies requirements.
