Carry-on Compliance

Disclaimer: We take the measurements of the bag provided by the manufacturer and compare them to the allowance listed on airline websites. This should be used as a guideline rather than a rule. Bags can change size as you pack them out, and every airline's interpretation of compliance is different. Just because a bag is listed as carry-on compliant here doesn't mean that the airline will interpret it that way.
