There is no universal cabin allowance. The operating carrier, fare and aircraft can all matter. Our atlas is a dated reference to primary airline policies, with personal and overhead bags kept separate. It is designed to help you ask the right question of your booking.
Check the source again before travelling. When an airline’s published inch and centimetre figures round differently, the fit tool preserves those figures rather than inventing a single exact conversion.
Read the whole allowance
An allowance describes more than size. It may specify item count, weight, storage category and eligibility by fare. Identify the operating carrier on each segment and keep personal-item, cabin-bag and checked-bag rules separate. A retailer’s description cannot grant permission to bring a bag.
Use the atlas as a dated reference
Our atlas preserves individual airline profiles and the source links. It does not invent a universal international limit or numeric personal-item dimensions where the source does not provide them. Recheck the booking and policy before departure, especially after an itinerary or fare change.
The checks worth making
- Operating carrier for every segment
- Personal versus overhead entitlement
- Published size and weight
- Aircraft and connection exceptions
