DENFrontier Fleet & Aircraft Types
8 aircraft types appear on F9 routes. This includes aircraft operated by partner airlines, not just Frontier metal.
Frontier Operating Partners
Not every flight with a F9 number is actually Frontier. These partner airlines operate routes under the F9 code. Your booking and flight number say F9, but the plane and crew belong to one of these carriers.
These are codeshare arrangements where Frontier sells seats on partner flights. The experience depends on the partner airline, not F9.
