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. Established on 8 August 2010, Trinity Airways has grown from a small domestic operator into one of South Korea's leading budget airlines, offering both domestic and international scheduled passenger services across Asia, Oceania, and Europe. The airline's primary hubs are Incheon International Airport (ICN), Gimpo International Airport (GMP), and Daegu International Airport (TAE).

Originally founded as Hansung Airlines in 2005, the carrier underwent restructuring and rebranded as T'way Air in 2010. Since then, the airline has steadily expanded its route network, fleet size, and service offerings. Trinity Airways is now part of the Daemyung Sono Group, South Korea's largest hospitality conglomerate, following an acquisition completed in early 2025. The airline is undergoing a strategic transformation, positioning itself as a hybrid carrier that combines low-cost efficiency with premium service elements on long-haul routes.
