Key Points

Asiana will exit Star Alliance at 23:59 Korea Standard Time on December 16, 2026, with the merger into Korean Air taking effect on December 17, 2026.

After the exit, Star Alliance will continue with 25 member airlines, and 14 member carriers are expected to continue serving Seoul Incheon International Airport with more than 1,900 monthly flights to 29 destinations.

Mileage accrual and eligibility rules are being phased with airline-specific cutoffs: Asiana Club miles can be earned on Star Alliance flights through December 16, 2026, but accrual toward other carriers’ mileage programs applies only to flights taken through October 15, 2026; ticketing/travel cutoffs vary by airline (e.g., Oct 31, Nov 30, Dec 16; some airlines allow travel through Dec 16, 2027 if tickets issued by Dec 16).

Back-end systems are already being reconfigured to operate without Star Alliance, with restrictions on award bookings starting December 1, 2026.

Asiana joined Star Alliance in 2003 as the 15th full member, underscoring a 23-year history with the alliance before the exit.
Asiana Airlines will leave Star Alliance at 23:59 Korea Standard Time on December 16, 2026 — ending 23 years of membership — before merging into Korean Air the very next day, according to Travel Trade Journal. The exit marks a full shift to SkyTeam and the permanent retirement of the Asiana brand.
Asiana joined Star Alliance in 2003 as its 15th full member. The departure clears the way for a single mega-carrier under Korean Air, which completed a 63.9% majority stake acquisition of Asiana in December 2024, according to DJ's Aviation.
A 23-Year Alliance Partnership Comes to a Close
Star Alliance CEO Theo Panagiotoulias thanked Asiana for its "two decades of contribution" to the network, according to Travel Trade Journal. He stressed that the alliance stays strong. After Asiana leaves, Star Alliance will still count 25 member airlines. Fourteen of those carriers will keep flying to Seoul Incheon Airport, running more than 1,900 monthly flights to 29 destinations.
The merger was born of financial crisis, not ambition. Asiana's parent company, Kumho Asiana Group, faced a severe debt crisis starting in 2019. A planned acquisition by HDC Hyundai Development collapsed when COVID-19 hit. By late 2020, the South Korean government decided the market could not support two full-service carriers. Korean Air stepped in with a â‚©1.8 trillion (about $1.6 billion) deal backed by the Korea Development Bank, according to Aeronews Global.
Mileage Cutoffs and Award Booking Freezes Explained
The transition comes with a series of hard deadlines that frequent flyers need to track. Asiana Club members can earn miles on Star Alliance flights through December 16, 2026. But members of other Star Alliance programs — like United MileagePlus or Lufthansa Miles & More — can only earn miles on Asiana flights taken through October 15, 2026, according to Airliner GS.
Award booking freezes hit even earlier. Backend systems stop accepting new Star Alliance award reservations on December 1, 2026 — more than two weeks before the exit. Ticketing cutoffs vary by partner airline: some stop selling on October 31, others on November 30, and some allow travel as late as December 16, 2027, if tickets were issued before December 16, 2026, according to Travel and Tour World.
Asiana Miles Convert to Korean Air SKYPASS at Two Rates
Asiana Club members will move into Korean Air's SKYPASS loyalty program. Miles earned directly from flights convert at a 1:1 rate. But miles earned through credit cards or hotel partners convert at just 1:0.82 — an 18% cut for those with partner-earned balances. All transferred miles will stay valid for 10 years inside the SKYPASS system, according to Travel and Tour World.
Korean Air Chairman Cho Won-tae called the merger a move about "reshaping the aviation industry and building a competitive aviation ecosystem" to rival the world's top 10 airlines. The combined carrier will fly roughly 230–240 aircraft and is projected to generate ₩23 trillion (about $16.6 billion) in annual revenue. Integration costs are estimated at up to ₩1 trillion ($654 million), with annual savings of ₩300 billion ($218 million) expected from 2028 onward.
A Reshuffled Northeast Asia Sends More Power to SkyTeam
Korean Air is already a SkyTeam member. Folding Asiana into it gives that alliance a near-monopoly on premium corporate travel through Seoul Incheon — one of Asia's busiest hubs. Star Alliance will now lean on ANA and EVA Air to serve South Korean demand, according to Airliner GS.
Asiana's low-cost subsidiaries, Air Busan and Air Seoul, are also being folded into Korean Air's Jin Air brand. That creates a dominant short-haul carrier across North Asia. The European Commission approved the deal in February 2024 only after Korean Air agreed to give up Asiana's cargo business and hand over slots on four European routes to remedy carrier T'way Air, according to DJ's Aviation.
