Key Facts: Airline Radio Callsigns

  • Aviation callsigns are allocated by the International Civil Aviation Organization (ICAO) to avoid confusion on crowded radio frequencies.
  • While most airlines use their commercial brand name as their callsign, historic flag carriers frequently preserve symbolic heritage names (e.g. Speedbird, Shamrock, Springbok).
  • Merged airlines occasionally preserve the target carrier's callsign for operational continuity; America West's "Cactus" survived on US Airways until 2015.
