Air Busan Co., Ltd. (298690.KS) operates as a low-cost carrier providing passenger air transportation services, including domestic and international flights from its primary hub at Gimhae International Airport in Busan, South Korea; cargo transportation; product brokerage; and sales of medical devices and health functional foods. Founded in 2007 and headquartered at 6 Yutongdanji 1-ro, Gangseo-gu, Busan, the company serves routes across South Korea and international destinations in Asia, such as Japan, China, the Philippines, and Vietnam, primarily targeting leisure and regional travelers as a subsidiary of Asiana Airlines, Inc., which holds a significant stake. It maintains a fleet suited for short- and medium-haul operations, emphasizing affordable fares and expanding connectivity from Busan. In May 2025, Air Busan received KRW 100 billion ($71 million) in funding from parent Asiana Airlines through the purchase of perpetual convertible bonds bearing 5.55% annual interest, aimed at bolstering its financial structure amid internal and external uncertainties and ahead of potential integration into Korean Air's low-cost carrier network following Asiana's acquisition. The company has also resumed and launched seasonal routes, including Busan-Hanoi after a six-year hiatus and Busan-Nagasaki charters into 2026, while preparing for broader network adjustments under the ongoing Korean Air-Asiana merger finalized in late 2024.
