Korean Air–Asiana merger confirmed, ending Star Alliance redemptions by December 1

Quick summary

Korean Air and Asiana Airlines will complete their merger on December 17, 2026, ending Asiana’s membership in Star Alliance and shifting South Korea’s second-largest carrier into SkyTeam. Aeroplan members are reportedly required to book Asiana flights using Star Alliance miles by December 1, 2026 — 16 days before the operational cutoff. Asiana Club balances will auto-convert to Korean Air SKYPASS at a rate that has not been publicly disclosed.

The merger required approval from 14 global regulatory bodies, including the U.S. Department of Justice. Existing Star Alliance award bookings on Asiana remain valid through their ticketed travel date — but the window to make new ones is closing fast.

Six years of regulatory battles ended when Korean Air and Asiana Airlines boards approved their merger agreement, with the news publicly confirmed on May 14, 2026. The formal integration date is December 17, 2026 — the day Asiana ceases to exist as an independent carrier and South Korea’s aviation market consolidates around a single flag carrier operating under SkyTeam.

For Star Alliance members, the practical deadline arrives sooner. Aeroplan members are reportedly required to complete new award bookings on Asiana-operated flights by December 1, after which Asiana will no longer accept Star Alliance award redemptions. That gives Air Canada, United Airlines, and Singapore Airlines loyalty members roughly six months to act — or permanently lose access to one of Asia’s most extensive route networks through their programs.

Korean Air acquired a 63.88% stake in Asiana for approximately $559 million, a transaction that began with Hanjin Group’s broader KRW 3.6 trillion acquisition of Asiana in November 2020. The combined carrier will operate a fleet of approximately 240 aircraft and absorb Asiana’s low-cost subsidiaries — Air Busan and Air Seoul — into Jin Air, Korean Air’s existing budget operation.

Asiana Club frequent flyer balances will convert to SKYPASS. The conversion rate has not been disclosed publicly, and the loyalty program integration plan was still pending South Korean Fair Trade Commission approval as of the merger announcement.

What the merger means for your existing bookings and miles

The alliance exit has a specific sequence that travelers need to understand. Asiana’s departure from Star Alliance is confirmed for December 17, 2026. Award booking access closes December 1 — not December 17. That 16-day gap is not a grace period; it is the administrative window airlines use to process final ticketing before the alliance database removes Asiana inventory entirely.

Existing Star Alliance award bookings on Asiana flights remain protected through their ticketed travel date. If you already hold a confirmed, ticketed itinerary on an OZ flight code booked through Aeroplan or another Star Alliance program, that booking is valid. What ends on December 1 is the ability to make new ones.

The codeshare picture is more complicated. Air Canada, United, and Singapore Airlines currently market Asiana-operated flights under their own flight codes. Those arrangements terminate on December 17. Passengers booked on partner codes for travel after that date will need to rebook on Korean Air or SkyTeam carriers — and the terms shift accordingly. Lounge access for Star Alliance Gold members on Asiana flights ends; Delta Sky Club or Air France lounge access applies only if the passenger has reboooked onto a SkyTeam carrier. Rebooking rights revert from Star Alliance reciprocal agreements to Korean Air’s unilateral policy.

The merger required sign-off from 14 global regulatory bodies — a number that reflects how extensively Asiana’s routes overlap with international aviation agreements. U.S. Department of Justice approval came in December 2024; South Korean Ministry of Land, Infrastructure and Transport approval followed in May 2026. Full regulatory detail is available via the merger regulatory timeline.

How the United–Continental merger tells us what to expect

This is not the first time a major Star Alliance carrier has been absorbed into a rival alliance — and the United–Continental merger of 2012 offers a precise calibration point. Continental’s OnePass program converted to United MileagePlus at a 1:1 rate, which was favorable. But award availability to Continental’s hub cities — Houston and Newark — dropped by roughly 40% for non-United members during the first year post-merger, as partner inventory dried up during integration.

The parallel for Korean Air–Asiana is direct. Star Alliance members booking South Korea routes through Aeroplan or MileagePlus should expect a similar contraction in available award seats after December 17. SkyTeam members — Delta, Air France, China Eastern — will gain access to Asiana’s routes, but award availability typically decreases during operational integration regardless of which alliance benefits.

One difference: Continental’s new bookings closed 90 days before the merger. Asiana’s window is longer, but the December 1 cutoff still compresses the practical booking horizon. Members who wait until November to act will find award inventory already depleted by earlier movers — a pattern that played out identically in 2012.

Steps to protect your miles and bookings before December 17

Star Alliance members with South Korea travel plans face a hard deadline sequence — December 1 for new award bookings, December 17 for everything else. Acting in the wrong order costs you options that cannot be recovered.

• If you hold an existing Asiana award booking via Aeroplan: Confirm it is fully ticketed — not just held — before December 1. Log into aeroplan.com and verify the booking shows a ticket number. If it is not yet ticketed, call Aeroplan at 1-800-361-5593 immediately to lock in Star Alliance routing before the cutoff.
• If you are planning a trip to or from South Korea after December 17: Book Korean Air directly or through SkyTeam partners — Delta, Air France — starting December 18. Star Alliance award bookings will not be available on Korean Air-operated flights. Search Google Flights for Korean Air availability and cross-reference with your SkyTeam program’s award calendar.
• If you hold Asiana Club miles: Redeem them for Asiana flights before December 17. Visit asiana.co.kr to check remaining award availability. After December 17, your balance auto-converts to SKYPASS at an unconfirmed rate — there is no opt-out and no reversal. Call Asiana Club at +82-2-2188-0114 to confirm conversion terms before the deadline.
• If you are booked on a United or Air Canada flight operated by Asiana: Check whether your travel date falls after December 17. If it does, contact the marketing carrier now to confirm rebooking options under Korean Air’s SkyTeam terms — baggage allowances and lounge access may change.

Watch: South Korean FTC final approval of the loyalty program integration plan is expected by June 30, 2026. If approved, SKYPASS conversion rates will be published — giving Asiana Club members a clear picture of what their balances are worth. If the FTC delays past August, expect uncertainty on balance value to persist through the December 17 merger date.
