Korean Air and Asiana Airlines have set a hard deadline on the longest-running airline merger of the decade. The boards of both carriers approved the final integration agreement on May 13, 2026, and the legally binding contract is being executed today, May 14, paving the way for Asiana Airlines to disappear as a brand on December 17, 2026.
The December 17 Switch-Over
Under the agreement, Korean Air will absorb the entire commercial operation of Asiana including 86 mainline aircraft, 22,000 employees, and a route network spanning 76 international and 14 domestic destinations. The combined airline will keep the Korean Air name and SkyTeam alliance affiliation, while Asiana's Star Alliance membership will lapse on December 16. Asiana's loyalty programme will fold into Korean Air's SKYPASS, and a unified passenger service system is targeted for go-live on the same day.
Five Years From Pandemic Rescue To Single Airline
The deal traces back to November 2020, when the South Korean government engineered a rescue takeover of cash-strapped Asiana to prevent a second-flag carrier collapse during the pandemic. Regulatory approvals from the European Union, the United States, China, Japan, and the United Kingdom required Korean Air to surrender lucrative slots and divest cargo operations to ease antitrust concerns. The final hurdle was cleared earlier this year when the US Department of Transportation signed off on the consolidated transpacific schedule.
What Happens to Air Busan, Air Seoul, and Jin Air
The agreement also locks in the long-discussed merger of the three subsidiary low-cost carriers. Air Busan, Air Seoul, and Jin Air will all consolidate under the Jin Air brand, creating South Korea's largest budget airline by fleet size. Korean Air's leadership has indicated the final unified airline will officially relaunch with a refreshed brand identity and a new aircraft livery in early 2027, with the first painted jet expected to enter service in March. The combined carrier will operate around 250 aircraft and rank among the global top 10 by international passenger traffic.
