About cabinbagsize.com

Airline bag rules are split across fare pages, help articles and booking screens, and they change often. Third-party guides regularly go out of date. This site checks your exact bag against your exact ticket on 29 airlines, and shows the date we last confirmed each rule on the airline’s own website.

Independent

cabinbagsize.com isn’t owned by or affiliated with any airline or airport. Airline names are used only to describe their published rules.

How the site is funded

The checker is free and needs no account. In future we may show clearly labelled links to bags that fit an airline’s free size, or to travel products, and earn a commission if you buy. That never changes a result — the answer always comes from the airline’s published rules. Any paid link will be labelled where it appears.

Accuracy

We work hard to keep every figure correct, but gate staff have the final say. Always check with your airline before you fly. Read how we check the rules, or tell us about a mistake.
