In November 2020, the government of Korea proposed the combination of Korean Air and Asiana to create a national champion carrier and rescue Asiana, which was ailing at the time. In February 2023, it was confirmed that the merger would not proceed without approval from European Union and United States authorities. At the time, the Korean government did not view approval in the EU and US as likely. Backup plans such as an equity investment from foreign backers (with the UAE-based
Mubadala Investment Company suggested) into Asiana to help it remain viable were being explored. In May 2023, it was reported that the
United States Department of Justice was considering filing suit to block the merger as anticompetitive. By June 2023, the merger was viewed as increasingly unlikely given the regulatory headwinds. In August 2023, the
Korea Economic Daily reported that the Korean Development Bank was seeking a plan B in preparation for the proposed merger's collapse. This was due to a rising belief that American and European authorities would block the consolidation. On September 27, 2023,
Yonhap reported that Korean Air had submitted an amended application to the European Commission, proposing divestment of Asiana's cargo division and giving up slots at some EU airports, including Barcelona, Rome, Paris, and Frankfurt to satisfy competition concerns. As of February 2024, authorities in one essential market, the
United States, had yet to approve the merger. After Korean Air switched to a new plan that consisted of acquiring a 63.88% stake of Asiana Airlines instead of a full merger, approval was granted by the U.S. Department of Justice in December 2024, which allowed the acquisition to be completed.
European Union On March 17, 2023, the
European Commission (EC) released the results of an in-depth investigation concluding that the merger would restrict competition with a concentration of market power between Europe and Korea. Specifically, the Commission cited reduced competition on passenger routes between South Korea and France, Germany, Italy, and Spain and reduced competition for
air cargo between all of Europe and South Korea. The Commission suspended its investigation into the merger in June 2023 due to the companies' failure to provide proposed corrective remedies before the commission's deadline. Korean Air would also sell
Asiana Airlines' cargo division, with the Asiana board giving its approval to the plan in November 2023. Korean Air resubmitted its application to the European Commission with these concessions for evaluation on November 2, 2023. However,
Yonhap has reported that the commission has not resumed its investigation due to "missing information" in the submission provided by Korean Air and Asiana. In February 2024, Korean Air secured conditional Commission approval for the consolidation of South Korea's aviation market contingent on an acceptable buyer being identified for its cargo business and making assets available to
T'way Air to start service on routes to Barcelona, Frankfurt, Paris, and Rome.
Japan In November 2023, Japan officially moved to block the merger, citing the combined power the merged carrier would have on air traffic between Japan and South Korea where it would represent nearly 70% of flying. The objection also cited the planned merger of the two airlines' three low-cost carrier subsidiaries. Japan approved the merger on January 31, 2024.
South Korea The Fair Trade Commission (FTC) approved the merger on February 22, 2022, with conditional clearance requiring the combined airline to give up some of their airport slots and transportation rights in certain regions. The Commission assessed that the merger would result in a monopoly on 26 international routes and 14 domestic routes but deferred to overseas authorities to on corrective action by granting 10 year conditional clearance with the following conditions: • Structural measures, including transferring the domestic and international slots and transportation rights further 10 years. • Restriction measures include limiting the price of airfare and prohibiting supply reduction. • Maintaining the qualities of customer service • Submitting the plan to integrate the mileage within 6 months, execute after the approval from FTC.
United Kingdom The UK's
Competition and Markets Authority (CMA) postponed the review of the merger in November 2022, citing monopoly concerns, giving Korean Air time to propose a plan to resolve competition concerns. Korean Air proposed transferring slots for seven weekly operation rights to
Virgin Atlantic to launch a
London–Heathrow to
Seoul–Incheon route as a remedy. The United Kingdom officially approved the merger on March 1, 2023. To gain approval for the merger, Korean Air proposed transferring several operations to
Air Premia. The transfer would include aircraft and flight crews. The DOJ rejected this proposal.
Non-essential countries In addition to essential countries, the companies sought review of the merger by authorities in countries considered to be "non-essential" markets. In June 2021, the
Philippines was the first "non-essential country" to approve the merger.
Australia,
Malaysia,
Singapore,
Taiwan,
Thailand,
Turkey, and
Vietnam have also officially approved the merger. == Public reaction to proposed merger ==
