About the "CHONG QING" Callsign
When Chongqing Airlines pilots communicate with air traffic control, they identify themselves using the radio callsign "CHONG QING" followed by the flight number spoken in aviation pronunciation. For example, flight 456 would be "CHONG QING Four Five Six." Radio callsigns are assigned by ICAO and are distinct from the airline's marketing name.
