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