Korean Air faces FTC action over Asiana merger seat capacity breach
Synopsis
South Korea's antitrust watchdog has moved to penalise Korean Air, Jin Air, and Asiana Airlines for allegedly falling below the 90-percent seat capacity threshold required as a merger condition — and has recommended a criminal referral. With the full Korean Air–Asiana merger set for December, this regulatory challenge could not have come at a more consequential moment.
Key Takeaways
South Korea's Fair Trade Commission (FTC) began deliberations on 30 September over alleged seat capacity violations by Korean Air , Jin Air , and Asiana Airlines .
The airlines allegedly provided fewer than 90 percent of 2019 -level seats on the Cheongju–Jeju route between December 2024 and December 2025 .
The examiner's report recommended penalties and a criminal investigation referral for noncompliance.
A separate request by Korean Air to lower the seat capacity requirement from 90 percent to 70 percent on Incheon/Busan–Guam routes was also recommended for rejection.
Asiana Airlines is set to formally merge with Korean Air on 17 December .
South Korea's antitrust regulator, the Fair Trade Commission (FTC), announced on Wednesday, 30 September that it has commenced formal deliberations on allegations that Korean Air Lines failed to honour seat capacity commitments made as conditions for its takeover of Asiana Airlines. The case centres on routes connecting Cheongju and the resort island of Jeju during the period from December 2024 to December 2025.
What the Examiner's Report Found
The FTC's examiner's report recommended action against Korean Air, its affiliate Jin Air, and Asiana Airlines for allegedly providing fewer than 90 percent of the seats offered on the Cheongju–Jeju route compared with 2019 levels. Under the merger approval conditions, the watchdog had required the carriers to maintain seat capacity on designated routes at no less than 90 percent of corresponding 2019 benchmarks.
The report concluded that the airlines had violated these requirements and recommended imposing penalties for noncompliance. Notably, it also recommended referring the case for criminal investigation — a significant escalation beyond routine regulatory fines.
Second Case: Capacity Reduction Request Rejected
In a separate but related matter, the examiner's report recommended rejecting a request by Korean Air and four affiliated airlines to lower the minimum seat capacity threshold from 90 percent to 70 percent of 2019 levels on routes connecting Incheon and Busan to Guam. The airline had cited the declining popularity of the U.S. territory as a tourist destination in seeking the relaxation. Examiners determined that the prevailing circumstances did not meet the criteria required to modify the existing requirements.
What Happens Next
The FTC will issue its final decisions following deliberations at a plenary session. Affected parties — including Korean Air, Jin Air, and Asiana Airlines — will be given an opportunity to present their defence before any ruling is handed down. The outcome will be closely watched given that Asiana Airlines currently operates as a subsidiary of Korean Air, and the two carriers are scheduled to formally merge into a single corporate entity on 17 December.
Merger Timeline Under Scrutiny
The allegations arrive at a critical juncture. The Korean Air–Asiana merger, one of the largest aviation consolidations in Asia in recent years, cleared multiple regulatory hurdles across jurisdictions before receiving conditional approval. The seat capacity requirements were among the key remedies designed to protect consumers from reduced competition on domestic and regional routes. A finding of noncompliance could complicate the final integration scheduled for December, and raises broader questions about post-merger regulatory oversight in the South Korean aviation sector.
Point of View
Not soft guidance. What is often missed in coverage of aviation consolidations is that the real consumer protection test comes after the deal closes, not before. Korean Air secured regulatory clearance by promising to maintain seat supply; the allegation that it fell short within the first year of oversight is precisely the scenario critics of the merger warned about. With the full legal merger just weeks away, the FTC's final ruling will set a precedent for how seriously South Korea enforces remedies in future M&A approvals.

Frequently Asked Questions
Why is South Korea's FTC investigating Korean Air?
The FTC is investigating Korean Air, Jin Air, and Asiana Airlines for allegedly providing fewer than 90 percent of the seats offered in 2019 on the Cheongju–Jeju route between December 2024 and December 2025. Maintaining that 90-percent threshold was a condition imposed by the FTC when it approved Korean Air's takeover of Asiana Airlines.
What penalties could Korean Air face?
The FTC examiner's report has recommended imposing financial penalties for noncompliance and referring the case for criminal investigation. The FTC will make its final decision after a plenary session, during which the airlines will have an opportunity to present their defence.
What was the request to lower the seat capacity requirement about?
Korean Air and four affiliated airlines sought to reduce the minimum seat capacity requirement from 90 percent to 70 percent of 2019 levels on routes between Incheon and Busan and the U.S. territory of Guam, citing declining tourist interest in Guam. FTC examiners recommended rejecting this request, finding the circumstances did not meet the criteria for modifying the conditions.
When is the Korean Air–Asiana merger expected to complete?
Asiana Airlines currently operates as a subsidiary of Korean Air, and the two carriers are scheduled to formally merge into a single corporate entity on 17 December. The FTC's ongoing deliberations could affect the timeline or conditions surrounding that final integration.
What were the original merger conditions set by the FTC?
As a condition for approving Korean Air's acquisition of Asiana Airlines, the FTC required the merged entity and its affiliates to maintain seat capacity on designated routes at no less than 90 percent of the levels recorded in 2019, a benchmark year used to measure pre-merger competition. The conditions were designed to prevent a reduction in consumer choice following consolidation.
