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