Asiana Leaves Star Alliance December 16: Earn and Book Star Awards Before the Deadlines

Asiana Airlines exits Star Alliance on December 16, 2026, ahead of its merger with SkyTeam's Korean Air. If you use Star Alliance miles on Asiana, two deadlines matter now.

• What is happening: After 23 years in Star Alliance, Asiana leaves on December 16 and merges with Korean Air the next day. Korean is a SkyTeam carrier, so Asiana will move toward SkyTeam over time.
• Earn deadline (Oct 15): You can earn Star Alliance miles on Asiana-operated flights departing on or before October 15, 2026. After that, Asiana flights stop crediting to Star programs.
• Redeem deadline (Dec 16): You can still use Star miles (United MileagePlus, Air Canada Aeroplan, and others) for awards and upgrades on Asiana through December 16, 2026.
• What it means: If a Star award on Asiana was on your list (a solid way into Seoul and Asia), book it before December 16. If you credit Asiana flights to a Star program, fly by October 15.
• Down the road: Once merged, Asiana's partnerships shift toward SkyTeam (Delta, Air France, KLM, Korean), changing which miles work on those flights.

Bottom line: Two dates. Fly Asiana by October 15 to earn Star miles; book Star awards on Asiana by December 16. After that, it becomes a SkyTeam story.
