About United Airlines

United Airlines, based in United States, operates under the ICAO code UAL and the IATA code UA; its radio callsign is "United". On this page you can follow United Airlines flights and find the airports it serves.

How to read a United Airlines flight number

Every United Airlines flight number starts with UA, 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 UAL, and controllers address it as "United". One thing to watch: codeshares. A ticket sold by another airline can be operated by United 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 United Airlines

Where is my United Airlines flight right now?

Search the flight number (UA 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 United 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 UA and UAL mean on United Airlines flights?

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

Does United Airlines operate flights for other airlines?

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