Atatürk Airport (IATA: ISL, ICAO: LTBA) is an airport currently in use for private jets. It used to be the primary international airport of Istanbul and the hub of Turkish Airlines until it was closed to commercial passenger flights on 6 April 2019. From that point, all passenger flights were transferred to the new Istanbul Airport. Since the move of commercial operations to the new airport, Atatürk Airport is open to general aviation and functioning as an executive airport.
