Federal Express Flight Status
About Federal Express
Federal Express, based in United States, operates under the ICAO code FDX and the IATA code FX; its radio callsign is "Fedex". On this page you can follow Federal Express flights and find the airports it serves.
How to read a Federal Express flight number
Every Federal Express flight number starts with FX, 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 FDX, and controllers address it as "Fedex". One thing to watch: codeshares. A ticket sold by another airline can be operated by Federal Express 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 Federal Express
Where is my Federal Express flight right now?
Search the flight number (FX 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 Federal Express 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 FX and FDX mean on Federal Express flights?
They are two prefixes for the same airline. FX is the IATA code you see on tickets; FDX is the ICAO code used in flight plans and by air traffic control.
Does Federal Express operate flights for other airlines?
Codeshare agreements mean a flight sold under another carrier's number may be operated by Federal Express, and the reverse. Live tracking always follows the operating carrier's flight number; check the "operated by" line on your booking.
