We do our best to keep our product measurements and airline size guidance up to date, but airline carry-on rules can change at any time and may vary by route, fare type, aircraft, and individual airline policies. We recommend checking directly with the airline before you travel to confirm the most current requirements. Travelpro is not responsible for any changes to airline policies or for items not meeting current carry-on restrictions. This information is provided as a helpful guide only and does not guarantee acceptance by any airline.
