The company’s main products and services include scheduled airline services covering a wide network within South Korea with key hubs at Seoul Incheon, Jeju, and Busan airports, as well as international routes to destinations in Asia including Japan, China, Southeast Asia, and Oceania.

Founded in 2008 and headquartered in Seoul, Jin Air is a wholly owned low-cost subsidiary of Korean Air. The company has established itself as Korea’s largest low-cost carrier by number of domestic routes and is known for pioneering the use of widebody aircraft (Boeing 777-200ER) in the low-cost segment, especially on long-haul routes such as Incheon to Honolulu. It maintains a strategic focus on expanding its route network, fleet modernization, and sustainable operations.
In recent years, Jin Air has undergone significant strategic developments including involvement in the post-merger integration plan following Korean Air’s acquisition of Asiana Airlines, which involves the consolidation of Jin Air with Asiana’s low-cost subsidiaries Air Seoul and Air Busan under a unified Jin Air brand. To support environmental sustainability, Jin Air has implemented advanced fuel management software SkyBreathe® to reduce carbon emissions, introduced new fuel-efficient Boeing 737-8 MAX aircraft, and started refueling with a Sustainable Aviation Fuel (SAF) blend on select routes. In 2024-2025, the airline expanded its fleet to 31 aircraft and launched new routes, including Incheon to Taichung and reactivated the Incheon-Cebu route, demonstrating ongoing capacity growth and network expansion. Jin Air continues to leverage technology partnerships, such as with Cloudflare, to enhance its online customer service and operational efficiencies. These combined efforts reinforce Jin Air's vision to lead as Asia's premier utility low-cost airline delivering increased connectivity with competitive fares and eco-conscious operations.
