Trinity Airways (formerly T'way Air) Flights – Book on Traveloka

About Trinity Airways

Trinity Airways (formerly T'way Air) is a South Korean low-cost carrier operating under IATA code TW and ICAO code TWB, headquartered in Seoul, South Korea. Founded on 8 August 2010, Trinity Airways has grown from a small domestic operator into one of South Korea's leading budget airlines, offering scheduled domestic and international passenger services across Asia, Oceania, and Europe. The airline's main hubs are Incheon International Airport (ICN), Gimpo International Airport (GMP), and Daegu International Airport (TAE).

Originally founded as Hansung Airlines in 2005, the carrier was restructured and relaunched as T'way Air in 2010. Since then it has significantly expanded its route network, fleet size, and service offerings. In February 2025, Trinity Airways was acquired by Daemyung Sono Group, South Korea's largest hospitality conglomerate, and the airline was renamed Trinity Airways on 10 September 2026 after shareholder approval in March 2026 and regulatory sign-off. The TW flight code and flight numbers did not change. For travellers in Singapore, Trinity Airways is a useful option for reaching Seoul and exploring South Korea and other destinations across East Asia.
