How This Calculator Works
Since a bag can be rotated to fit an overhead bin, we sort your bag's length, width, and height from largest to smallest, and compare them against each airline's limit dimensions — also sorted largest to smallest — one axis at a time. If your weight is provided and the airline publishes a carry-on weight limit, that's checked too. Policies change and vary by fare class, so always confirm with the airline before you fly.
