The airline was developed to improve regional connectivity to Korea’s islands and underserved airports, with its name meaning “Island Air” in Korean. A core focus is Ulleungdo, an island in South Korea where an airport with a 1,200-metre runway is expected open in 2027. Japan could be on the cards as a future destination for the airline.
The next step for SUM Air will be the Air Operator Certificate (AOC) application, and the airline intends to operate a fleet of ATR 72-600s, due to the aircraft’s short take-off and landing capabilities and ATR’s well-developed network of maintenance and spare parts across Asia. ATR aims to have a total Korean fleet of 25-30 aircraft by 2030.
