callsign
The name a flight uses on the radio, usually an airline telephony name plus a flight number.
Also written
call sign
The telephony name is often nothing like the brand: British Airways is "Speedbird", KLM is "Rijnmond", Aer Lingus is "Shamrock". The callsign identifies the flight, not the airframe, so the same aircraft carries a different one on the way back.
