Does this tool replace the airline baggage sizer?

No. This is a planning helper. Airlines can enforce rules at the gate, and fare or aircraft type can change what is allowed.

How often is airline size data reviewed?

How we source luggage rules

Airline limits come from a structured JSON dataset with official or secondary source URLs and a "last verified" date per carrier. When a page shows a comparison table, each row links back to that airline's published policy.

We focus on outer dimensions because that is how airport sizers and published limits are usually written.
