Korean Air-Asiana Mileage Merger Approved; 10-Year Choice Set

Mileage Merger Approved: What Investors Should Check First

The mileage integration of Korean Air and Asiana Airlines preserves consumer choice while imposing a long-term supply obligation on Korean Air. According to Yonhap News, the Korea Fair Trade Commission approved the integration plan submitted by Korean Air on September 15, 2026. For investors, this decision does not mean the merger itself is complete; it clarifies the conditions under which the mileage systems must operate after the merger.

Separate mileage management means that even if the Asiana Airlines entity disappears, existing miles will not immediately be converted into Korean Air miles but will be administered separately. The scheduled merger date is December 17, 2026, and the separate-management period lasts 10 years from the actual merger date. However, it has not been confirmed whether the merger will be completed on the scheduled date.

A 10-Year Choice Matters More Than Immediate Integration

Existing Asiana Airlines customers can use unconverted miles for award tickets on all Korean Air-operated routes, seat upgrades, cash-and-miles payments, and shopping. The core of the approval plan is that delaying conversion still connects the available usage to Korean Air routes.

Customers who apply for conversion must transfer all of their Asiana Airlines miles. During the 10-year separate-management period, flight miles will convert at a 1:1 ratio, while partner miles will convert at a 1:0.82 ratio. Any miles remaining after the period ends will be converted automatically. The approval plan therefore does not allow customers to convert only part of their balance first.

Seat Supply Will Be Managed by Standards, Not Promises

From a market perspective, the more consequential provision concerns standards for maintaining award-seat availability. Korean Air must keep award-seat flight performance at or above the combined performance of both airlines in 2024 for 10 years after the merger. Long-haul and popular routes will be subject to a separate standard of at least their 2023 performance over the same period.

Korean Air must also submit annual peak-season award-seat supply data to the implementation oversight committee. This structure allows regulators to assess, using peak-season data separately, whether the overall performance target is being met mainly through off-peak supply. However, the specific number of award seats by route and the operating schedule for mileage-special flights have not been confirmed in publicly available information.

How Total Usage and Cash-and-Miles Payments Change the Terms

Korean Air must manage the annual mileage usage of members of both airlines. The benchmark is their combined usage in 2025, with targets of 106% in 2027–2028, 112% in 2029, and 121% in 2030–2036. These figures are management standards for total annual mileage usage, not the number of seats on any particular route.

The threshold for cash-and-miles payments will also be lowered. The minimum amount for Korean Air cash-and-miles payments will fall from 500 miles to 100 miles after the expansion, while the maximum share of a fare payable with miles will rise from 30% to 40%. Expanding access to smaller balance holders also broadens the paths to meeting the actual total-usage standard.

Membership Tiers and the Consumer Choice Divide

• After integration, Korean Air’s elite-member program will have four tiers, while the existing Asiana Airlines program has five membership tiers.
• Those who choose conversion will have their status reassessed based on the combined miles of both airlines. However, the specific tier each member will receive has not been confirmed.
• Members who meet the requirements to retain a time-limited elite status before integration will keep that status for 24 months after the expiration date of their existing qualification.
• The Korea Fair Trade Commission said it had “enabled members to use their miles across the expanded route network of both airlines without losing mileage value.”

Investment Boundaries for Korean Air and Asiana Airlines

• Korean Air is the directly responsible party: it must manage Asiana Airlines miles separately for 10 years and meet standards for award-seat flight performance and total annual mileage usage.
• Asiana Airlines is the company scheduled to merge, and its existing members’ miles and elite-status records will fall under the integrated system.
• This approval alone provides no basis for calculating changes in either company’s revenue, costs, earnings, or corporate value. Treating the finalization of consumer-protection terms as an immediate earnings improvement or deterioration would go beyond the available evidence.

Next, Watch Implementation Performance

The optimistic scenario is that Korean Air maintains the award-seat standards for 10 years after the merger while gradually increasing total annual mileage usage. In that case, the usage opportunities and conversion choice set by the approval plan would continue in actual operations.

The opposite scenario is that the scheduled merger is delayed or that route-level supply does not adequately reflect the intent of the approval plan. The next assessment will hinge on whether the merger is actually completed on the scheduled date, annual peak-season award-seat supply, and Korean Air’s implementation of the 106% total-usage standard in 2027–2028. What has been confirmed is approval of the system; specific supply volumes and earnings impacts still cannot be tied to the stock price.
