About Frontier Airlines

Frontier Airlines is an airline based in United States, listed under the ICAO code FFT and the IATA code F9; air traffic control addresses its flights by the callsign "Frontier Flight". On this page you can follow Frontier Airlines flights and find the airports it serves.

How to read a Frontier Airlines flight number

Every Frontier Airlines flight number starts with F9, followed by up to four digits: that is the number on your booking confirmation and boarding pass. In flight plans the same flight carries the ICAO prefix FFT, and controllers address it as "Frontier Flight". One thing to watch: codeshares. A ticket sold by another airline can be operated by Frontier Airlines and vice versa; live tracking follows the operating carrier's number, so if your search comes up empty, check the "operated by" line on your booking.

Frequently asked questions about Frontier Airlines

Where is my Frontier Airlines flight right now?

Search the flight number (F9 plus digits) in the search box on this page. If the aircraft is airborne within receiver coverage, you will see its live status; before departure you will see the route.

Is my Frontier Airlines flight delayed or cancelled?

Check the flight number on this page for live status, but for rebooking, gate changes and cancellations the airline itself remains the authoritative source.

What do F9 and FFT mean on Frontier Airlines flights?

They are two prefixes for the same airline. F9 is the IATA code you see on tickets; FFT is the ICAO code used in flight plans and by air traffic control.

Does Frontier Airlines operate flights for other airlines?

Codeshare agreements mean a flight sold under another carrier's number may be operated by Frontier Airlines, and the reverse. Live tracking always follows the operating carrier's flight number; check the "operated by" line on your booking.
