Ninety-nine point three percent of the votes cast at Asiana Airlines' extraordinary shareholder meeting in Seoul on Wednesday were in favor of dissolving the 37-year-old carrier and folding it entirely into rival Korean Air, according to Yonhap. The vote, taken with 81.86% of shares represented, is the last major corporate-governance milestone in a consolidation saga that has run for nearly six years, and it sets South Korea on course to have a single full-service national airline for the first time in the country's aviation history.

Hours after the shareholder vote closed, Korean Air's own board of directors ratified the merger agreement in a separate meeting, using a streamlined "small-scale merger" provision under Article 527-3 of Korea's Commercial Act that allowed the acquirer to bypass a full shareholder ballot, according to AeroTime. With both approvals now in hand, the two carriers are cleared to proceed into creditor-protection procedures and the remaining administrative filings needed to complete the corporate merger registration on December 17, 2026 — the date on which the integrated carrier is scheduled to begin flying under a single operating certificate, according to Korea Times.

A deal born from a 2020 bailout

The roots of Wednesday's vote trace back to November 2020, when the South Korean government, moving to rescue an aviation sector battered by the pandemic, orchestrated a plan for Korean Air to acquire its heavily indebted domestic rival in a transaction then valued at 1.8 trillion won, or roughly $1.6 billion, according to Yonhap. State-owned Korea Development Bank funneled financing through parent conglomerate Hanjin Group to help underwrite the acquisition, positioning it as much as an industrial-policy rescue as a straightforward corporate takeover. What followed was one of the most heavily scrutinized airline mergers of the decade: competition authorities in 14 separate jurisdictions, including the United States, the European Union, China and Japan, spent close to four years reviewing whether combining Korea's two largest carriers would concentrate too much market power on domestic and international routes.

That scrutiny forced Korean Air to restructure the deal more than once. Regulators in Brussels and Washington balked at a full outright merger over concerns it would eliminate competition on trans-Pacific and Korea-Europe routes, pushing Korean Air in 2023 to offer remedies that included divesting Asiana's cargo division and surrendering takeoff-and-landing slots at Barcelona, Rome, Paris and Frankfurt, according to a summary compiled by Wikipedia. The U.S. Department of Justice ultimately allowed the transaction to proceed as a controlling-stake acquisition rather than a full-entity merger, and the European Commission issued its final clearance in November 2024. Korean Air closed on a 63.88% stake in Asiana for roughly 1.5 trillion won that December, a step the WSJ described at the time as the conclusion of "a four-year merger journey."

Why a second vote was needed in 2026

The December 2024 closing did not fully merge the two airlines — it made Asiana a majority-owned subsidiary that kept its own brand, livery and frequent-flyer program while the companies worked through operational integration. What changed this spring was the mechanics of full absorption. On May 12, 2026, Korean Air agreed to acquire Asiana's remaining 36.12% stake for approximately 510 billion won, paid in newly issued shares rather than cash, according to a filing summarized by MarketScreener. The exchange ratio was fixed at 0.2736432 Korean Air shares per Asiana share, meaning Korean Air will issue roughly 20.34 million new shares, listing on January 4, 2027, according to Korea Times. Both boards signed the definitive contract on May 14, and Wednesday's votes formally ratified it — the step converting a majority stake into full absorption of Asiana's assets, liabilities, employees and operating certificate.

The mechanism: why full absorption matters more than a controlling stake

The distinction between owning a controlling stake and fully merging matters operationally and financially. As a subsidiary, Asiana retained its own Air Operator Certificate, its own frequent-flyer program and its own membership in the Star Alliance, creating duplicated overhead in maintenance, crew scheduling, IT systems and loyalty administration. Full absorption collapses those parallel structures into one. Asiana will exit Star Alliance and its flights will be reissued under Korean Air's SkyTeam membership, while its mileage program will be wound down and folded into Korean Air's SKYPASS, a process CEO Song Bo-young said the company is coordinating with Korea's Fair Trade Commission "to protect consumer interests" and minimize disruption, according to Korea Times. Song told shareholders after the vote that the outcome marked "the first step toward writing a new chapter in Korea's aviation industry as a megacarrier," a framing echoed by sedaily, which reported she called the transition a rebirth as "the integrated Korean Air."

Once finalized, the combined carrier is projected to serve more than 120 cities worldwide with a fleet exceeding 230 aircraft and roughly 28,000 employees, generating forecast annual revenue above 23 trillion won, or about $16.25 billion, according to Korea Times. Separate fleet data compiled from South Korean lawmakers' disclosures and reported by Sedaily put the combined roster at 212 passenger aircraft and 23 freighters, or 235 planes in total, up roughly 10 aircraft since the 2024 stake acquisition as Korean Air has continued taking new deliveries. That scale would place the merged carrier among the world's top 20 airlines by fleet size and make it, by Yonhap's account, one of roughly the tenth-largest airline globally by that measure when the deal was first floated in 2020.

Implication: a single dominant flag carrier, and what regulators extracted in return

The practical consequence for South Korea's aviation market is stark: Korean Air becomes the country's only full-service international carrier, holding a dominant domestic position that did not exist under a two-carrier structure. South Korea's transport ministry granted conditional approval in June, requiring Korean Air to maintain aviation safety standards and passenger convenience as it absorbs its former rival, according to AeroTime. Separately, Korea's Fair Trade Commission has said it will set up an oversight structure to track compliance with merger conditions and to support smaller regional carriers navigating a market now anchored by one dominant flag carrier, a commitment noted in coverage of the original 2024 stake closing by Reuters.

For travelers, the most visible near-term effects will likely be administrative rather than dramatic: loyalty conversions, alliance-membership switches affecting connecting itineraries, and consolidation of Asiana's budget affiliates, Air Busan and Air Seoul, alongside Korean Air's existing low-cost unit, Jin Air. Those integration mechanics, rather than any single dramatic disruption, are what regulators are watching most closely as the December 17 launch date approaches, marking the close of a restructuring that began under pandemic-era rescue logic and ends as a bet on scale in an increasingly consolidated global aviation market.
