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