Since early 2014 , Asiana Airlines had considered launching a second low-cost carrier ( LCC ) in addition to Air Busan . It initially faced difficulties in proceeding with the project because of the Asiana Airlines Flight 214 crash in July 2013 . Asiana has only a minority 46 % stake in Air Busan , while it has a controlling stake in Air Seoul . Air Busan is based in Busan , which has allowed other LCCs such as Jin Air and Jeju Air to fill the Seoul market ; Air Seoul is based in Seoul . 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
