The Korean Air-Asiana merger completes on December 17, 2026. On that date, Asiana Airlines will stop existing as an independent airline, and Korean Air will absorb its operations into a single carrier.
For business-class travelers, the change reaches well beyond a new logo on the aircraft. It affects loyalty programs, alliance benefits, lounge access, award bookings, and what happens if you already hold an Asiana Airlines ticket for travel after the merger.
Several important deadlines arrive before the integration itself. Knowing which ones apply to your miles, status, and booking can help you avoid unnecessary changes or missed opportunities.

What’s actually changing between Korean Air and Asiana
As of September 2026, Korean Air and Asiana Airlines are not the same airline yet. They remain separate until the merger completes on December 17. After that, Asiana Airlines ceases to exist as an airline altogether. Korean Air will absorb Asiana’s fleet, routes, staff, assets, obligations, and operating structure, and the Asiana brand will end.
The process started in November 2020, when Korean Air announced its plan to acquire Asiana. Korean Air completed its 63.88% controlling stake purchase in December 2024, making Asiana a subsidiary before the final integration.
The final corporate approvals arrived on August 12, 2026. Korean Air’s board ratified the merger that day, while Asiana shareholders approved it at an extraordinary general meeting with 99.3% of votes cast in favor. Those approvals cleared the companies to complete the remaining administrative steps before integration.
The Korean Air-Asiana merger creates one of the world’s ten largest airlines by fleet size. It also gives Korean Air control of a much broader combined route network and aircraft fleet.
After December 17, you will not be choosing between Asiana business class and Korean Air business class on former Asiana routes. You will be booking Korean Air, with Korean Air responsible for the product sold and operated across the combined airline.
The takeaway: If you specifically want to fly Asiana as Asiana, your opportunity ends with the merger on December 17.
Asiana before and after December 17
The corporate merger splits the systems, loyalty benefits, and alliance rules you use before and after integration.
| Benefit | Before December 17, 2026 | After December 17, 2026 |
|---|---|---|
| Alliance membership | Star Alliance member | Part of Korean Air’s SkyTeam operation, with no independent Asiana alliance status |
| Loyalty program | Asiana Club | Asiana Club closes to new members as Korean Air integrates the program into SKYPASS |
| Booking website | asiana.com | Korean Air booking systems |
| Operating carrier | Asiana | Korean Air |
| Lounge access | Eligible Star Alliance lounge access | SkyTeam lounge access under Korean Air’s rules |
Asiana Airlines remains a Star Alliance member through December 16, 2026. It does not independently switch alliances on December 17. As Asiana ceases to exist as a separate airline, its former operations become part of Korean Air’s SkyTeam network.
You can use Asiana’s Star Alliance benefits, including eligible lounge and elite benefits, only until December 16. They do not transfer to Korean Air after the merger. If you have an Asiana ticket scheduled for travel after December 17, Korean Air will take over the booking, and the flight will operate under Korean Air’s rules. Once that transition occurs, you will be eligible for the lounge access and other travel benefits associated with Korean Air and its SkyTeam membership, subject to your ticket, fare class, and elite status.
The takeaway: Use any Asiana-specific Star Alliance benefits before December 17, because they end when Asiana’s independent operation does.
If you’re holding Asiana miles or elite status: will they disappear?
No, Asiana miles or elite status will not disappear altogether, but Asiana Club miles will move into Korean Air’s SKYPASS structure as part of the integration. Mileage is the important exception to the December 17 cutoff: although Asiana Airlines itself disappears, the miles you have already accumulated do not simply vanish with it.
Korean Air’s integration plan lets you keep your current balance as “former Asiana Mileage” for up to 10 years. During that period, you can continue using those miles under the applicable redemption rules or choose to convert them into SKYPASS.
If you choose to convert before the 10-year period ends, you must convert your full remaining balance. Korean Air converts flight-earned Asiana miles at a 1:1 ratio and partner-earned miles at the ratio of 1:0.82. At the end of the 10-year period, Korean Air will automatically convert any remaining former Asiana Mileage into SKYPASS miles.
Mileage earning on Star Alliance flights also changes before the merger. For flights through October 15, 2026, you can enter your Asiana Club number during booking, ticketing, or check-in. For Star Alliance flights from October 16 through December 16, you need to request the mileage after completing your flight because automatic accrual will no longer work.
This mileage transition should not be confused with Asiana continuing as an airline. It does not. The mileage balance survives temporarily because Korean Air has created a conversion and redemption process for it.
If you hold Asiana elite status, Korean Air will match your status into its SKYPASS structure rather than make you start again. Korean Air will also honor your existing status validity period. The integration introduces Morning Calm Select, a new SKYPASS tier that accommodates qualifying former Asiana Club members within the new status structure.
If you already have an Asiana flight departing after December 17
If you hold a paid Asiana ticket for travel after December 17, Korean Air will take over Asiana’s contractual obligations when it absorbs the airline. You don’t need to buy the ticket again solely because the Asiana corporate entity disappears.
By the time you travel, Korean Air will be responsible for operating the flight, and your reservation will move into its systems. Your flight number, check-in details, seat information, and other booking details may change during the transition.
Award tickets require a different approach.
Do not treat an award that uses United MileagePlus, Air Canada Aeroplan, Lufthansa Miles & More, or another Star Alliance currency as identical to a paid Asiana ticket. Star Alliance award access to Asiana ends around the merger, and each loyalty program will control its own booking and travel deadlines.
There is also an important distinction if you used Asiana Club miles to book travel on another Star Alliance airline. Asiana states that those partner awards cannot continue beyond the applicable partnership end date. If an affected itinerary falls outside the permitted travel period, Asiana refunds the ticket and restores the miles without penalty.
This happens because Asiana’s independent Star Alliance membership ends with the merger as the airline ceases to exist independently.
If you hold a paid Asiana-operated ticket for travel after integration, keep the reservation and review every updated confirmation Korean Air sends you. For an award ticket, check the rules of the loyalty program that issued it rather than assuming the merger protects it automatically.
Can you still book Asiana business class right now?
Yes, but only if you specifically want to fly Asiana before the December 17 merger.
If you are considering an award ticket, check your loyalty program’s rules carefully. Star Alliance booking and ticketing deadlines vary by program and airline, so there is no single cutoff for every traveler. If you want to use Star Alliance miles for Asiana, confirm the final date before transferring any points.
Paid tickets follow different rules, but the Asiana booking operation will still end when the merger is complete. Travelers who want to experience Asiana business class should therefore book and travel before December 17. Afterward, premium-cabin bookings on the combined airline will be sold as Korean Air Prestige Class and will follow Korean Air’s SkyTeam arrangements.
If you are mainly interested in a business-class flight on a route formerly served by Asiana, compare Korean Air’s aircraft, seat map, and onboard product instead. That will give you a clearer idea of what to expect after the merger.
The takeaway: The Asiana booking and Star Alliance window is closing with the merger. After December 17, plan around Korean Air, not a continuing Asiana product.
What the merger means for your next business-class trip
If you already know and like Asiana’s business-class product, the most useful comparison after the merger is not Asiana before versus Asiana after, as there will be no “Asiana after” as a separate airline product. The relevant comparison is the Asiana experience you know today versus Korean Air Prestige Class.
The two products do not offer a like-for-like experience. Seat design, cabin layout, service style, lounge access, and onboard details differ across aircraft and between the two carriers. Do not assume a former Asiana route will deliver an identical premium experience when Korean Air takes over the flight.
For future bookings, research Korean Air’s Prestige Class product directly. Check which aircraft Korean Air schedules for your route, review the seat layout, and confirm the lounge access and onboard experience that come with that specific flight.
This becomes especially important as Korean Air incorporates former Asiana aircraft into its larger fleet. An aircraft that once belonged to Asiana can remain in service, but that does not mean Asiana Airlines or “Asiana business class” continues as a bookable product. Korean Air becomes the airline you book, and the aircraft type and seat map tell you what kind of business-class experience you are buying.
