Methodology

This Bag Fits uses source-dated airline rules and bag records. The first launch set favors official airline pages, manufacturer product pages, and clearly marked retailer records when manufacturer data is incomplete.

Fit results separate published dimensions from practical risk. A bag can be officially larger than a rule yet marked risky when it is soft, lightly compressible, and only slightly over. Rigid bags do not receive compression credit.

Unknown means the airline source did not publish enough exact dimensions for the rule. In those cases, the site should show conservative guidance and the relevant regional or fare note.

Recommendations are not guarantees. Airline staff, packed shape, handles, wheels, fare class, regional aircraft, and airport enforcement can change the outcome.

Flight-risk mode currently parses the airline code from the entered flight number, then uses user-supplied aircraft context to adjust risk and recommendations. It does not call a live flight-data provider until provider accuracy, cost, and display terms are verified.
