Airline Designators

In radio communications, most airliners, including cargo flights, will identify themselves using the name of the airline followed by the flight number. Airline callsigns exist for operations of all shapes and sizes, even as small as Cessna 172s! You’ll even see callsigns used by general aviation and private flights. 

If you wish to communicate with ATC using an airline callsign, you’ll need to connect to the network using:

  • A three-letter designator that corresponds to the callsign you wish to use, followed by;
  • A flight number, from one to four characters.

Some common examples of airline callsigns and corresponding operations are shown below.
