Korean Air–Asiana Merger Enters Final Stage, Integrated Carrier Set for December 17, 2026

Korean Air and Asiana Airlines have cleared one of the final major corporate hurdles in their long-running merger process. On August 12, 2026, Korean Air’s board and Asiana Airlines’ shareholders formally approved the merger agreement, with corporate merger registration currently scheduled for December 17, 2026.

At Asiana’s extraordinary general meeting, shareholders representing 81.86% of voting shares attended, and 99.3% of the votes cast supported the merger. The approvals formally confirm the agreement signed by the two carriers in May 2026 and move the process from corporate authorization toward operational integration.

The focus now shifts to the practical work of combining two large airlines. Reservation and IT systems, employee training, operational procedures, Air Operator Certificate amendments and international operating permits all need to be aligned before the integrated carrier can operate smoothly. Korean Air is continuing its post-merger integration program with an emphasis on minimizing disruption for passengers.

Frequent flyers should also pay close attention to the alliance transition. Asiana is expected to remain a Star Alliance member through December 16, 2026. After integration, customers will receive alliance benefits through Korean Air’s SkyTeam network. Passengers holding Star Alliance award bookings or planning to use partner mileage should therefore review the applicable rules as their travel date approaches.

The combination of South Korea’s two largest full-service airlines is expected to reshape capacity and connectivity across Northeast Asia. Over time, overlapping schedules, fleet deployment and airport operations may be reorganized, while the combined network could offer broader connecting options through Korea.

For passengers booked with Korean Air or Asiana around the end of 2026, it will be important to recheck flight numbers, check-in locations, baggage rules and mileage accrual shortly before departure—especially for travel on or after December 17. The merger is set to become one of the most consequential changes in Korean aviation in years, with direct implications for travelers between Korea and Vietnam, Japan, Southeast Asia, Europe and North America.
