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