Air Seoul is a South Korean low-cost carrier and a subsidiary of Asiana Airlines. The airline is based at Incheon International Airport in Seoul, from which it operates flights to international destinations.
Since early 2014, Asiana Airlines had considered launching a second low-cost carrier in addition to Air Busan. The goals of Air Seoul are to strengthen Asiana’s competition with other South Korean LCCs and to improve Asiana’s performance in certain markets, such as secondary Japanese cities. The airline was established in 2015 and started operations in 2016. The airline started flights to Japan in October 2016, its first international route.
