Find one bag size for every airline on your trip
Choose the airlines you plan to fly. CabinFit normalizes the three published edges and finds the strictest shared size, while keeping fare inclusion and weight conditions separate.

The smallest published edge sets each shared limit
Three fixed edges, with bag rotation
Source-qualified airline rules
Up to six airlines in one plan
Select your airlines
Choose between two and 6 airlines. Only current, source-qualified rules with three fixed dimensions are available.
1/6 selected
Select at least two airlines
The shared dimensions will appear here as soon as two eligible airline rules are selected.
CabinFit combines rules with three published edges and allows bag rotation; linear-total-only rules are excluded. Always check the operating airline, exact fare, ticket, weight conditions, and official source before travel.
