Japan Airlines and Korean Air Sign MOU Ahead of Asiana Merger

Japan Airlines Co., Ltd. (JAL) and Korean Air (KE) signed a Memorandum of Understanding on September 3, 2026, to expand their strategic partnerships ahead of Korean Air’s scheduled integration of Asiana Airlines. The agreement prepares the carriers to scale their bilateral cooperation across a significantly larger combined network.

In a press release, Japan Airlines stated the expanded alliance builds upon a 60-year relationship between the two flag carriers. The partnership will encompass expanded codeshare operations, frequent flyer program alignment, and joint initiatives in cargo, ground handling, and sustainable aviation fuel.

Preparing for the Asiana integration

The timing of the agreement aligns with the final stages of Korean Air’s acquisitions of Asiana Airlines. Following formal approvals from the Korean Air board and Asiana Airlines shareholders on August 12, 2026, the integrated airline is scheduled to launch on December 17, 2026.

Japan Airlines indicated that existing partnerships will be evaluated and progressively aligned with the expanded network of the integrated airline. According to AeroCorner, codeshare operations between Japan Airlines and Korean Air are expected to increase from approximately 250 weekly flights to roughly 400 weekly flights following the December integration.

The carriers plan to extend their cooperation beyond passenger flights. The memorandum outlines large-scale collaboration in operational areas including aircraft maintenance, cabin crew training, and ground handling services.

Financial ties and historical context

Alongside the operational agreement, Japan Airlines acquired an undisclosed equity stake in Hanjin KAL, the holding company of Korean Air. In a statement reported by The Korea Herald, Japan Airlines characterized the acquisition as an independent investments decision based on the long-term market value of Hanjin KAL. The exact size of the stake remains undisclosed, as no regulatory filings indicating a holding of five percent or more have been published.

The strategic partnership memorandum was signed in Tokyo by Japan Airlines President and Group CEO Mitsuko Tottori and Korean Air Chairman and CEO Walter Cho. The agreement marks a continuation of ties that began in April 1963 with an initial cooperation agreement, followed by the launch of joint flights between Japan and South Korea in the spring of 1964.

Japan Airlines stated the partnership will “elevate the strong cooperative system that both companies have cultivated to the next level, creating new value and customer experiences in the global market.”

AirPro News analysis

We view the timing of this expanded partnership as a strategic maneuver by Japan Airlines to secure its position in the Northeast Asian market ahead of the Korean Air and Asiana Airlines merger. By deepening ties now, Japan Airlines ensures it remains the preferred Japanese partner for the incoming mega-carrier. The equity stake in Hanjin KAL, while undisclosed in size, serves as a financial anchor to the operational memorandum. This investment likely provides Korean Air leadership with a stable, friendly shareholder as they navigate the complex final stages of the Asiana integration.
