SunExpress is a Turkish leisure airline founded as a joint venture between Turkish Airlines and Lufthansa, making it one of the few carriers co-owned by two major legacy airlines. Operating since 1990, the airline specializes in connecting sun destinations in Turkey and the Mediterranean with cities across Europe, primarily targeting the holiday and charter travel market. Headquartered in Antalya, Turkey, SunExpress serves a broad network of European cities with scheduled and charter flights, particularly during the summer tourism season. The airline operates under its own brand as well as a German subsidiary, SunExpress Deutschland, which has since been integrated into the main brand. SunExpress is known for its strong focus on leisure travel and has steadily grown its fleet and route network over the decades, positioning itself as a key player in the Turkish tourism aviation sector. It operates primarily from Antalya and Izmir, serving millions of holiday travelers each year.
