which carrier fits your airline

Which pet carriers fit each airline

Of the 15 in-cabin carriers we track, the number that clear each airline's published under-seat limit ranges from 0 (Vueling) to 14 (Pegasus Airlines). Height is the binding constraint almost every time — the limit airlines publish is a height test more than a footprint test.
