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