Will your carry-on fit?
Enter your bag dimensions and compare them with a verified airline allowance. Always confirm your exact fare before flying.
Common questions
Does orientation matter?
Sides are compared largest-to-smallest, so swapping length and width in the form should not change the result. Always check how your airline measures bags at the gate.
Why can a bag fail one fare and pass another?
Many airlines include only a small under-seat bag on the cheapest fare. A larger cabin bag often needs priority, a bundle, or a higher fare. The checker can point to another listed option for the same airline when the numbers allow it.
Is the weight check required?
No. Leave weight blank to check dimensions only. Weight is only failed if you enter a number and it exceeds a published limit.
