Jin Air, Air Busan, and Air Seoul Sign Merger to Create Unified Korean LCC Launching March 2027

The Quick Take

• Jin Air, Air Busan, and Air Seoul have signed a three-way merger agreement creating a unified LCC to launch as 'Integrated Jin Air' in March 2027
• Each airline's board approved the merger individually; shareholder votes are scheduled for December with regulatory approvals to follow
• The combined entity becomes Hanjin Group's single dominant low-cost carrier, reshaping Korea's LCC competitive landscape

Jin Air, Air Busan, and Air Seoul have executed a three-way merger contract following individual board approvals at each airline, creating a unified low-cost carrier that will operate as Integrated Jin Air from March 17, 2027. Shareholder votes are scheduled for December 2026 at each company, after which the merged entity will seek regulatory approval under Korea's aviation law before the final launch date. The merger consolidates Hanjin Group's three LCC brands — previously operating with overlapping routes and competing for the same passenger segments — into a single unified platform designed to compete more effectively against Jeju Air and T'way.

The creation of a single dominant Hanjin-group LCC reshapes the competitive landscape for Korean aviation significantly. Previously, the three-brand structure forced intra-group competition on overlapping routes, diluting yields and operational efficiency. The merger eliminates this inefficiency and creates a larger entity capable of negotiating better aircraft financing terms, slot allocations, and codeshare agreements. The unified Jin Air will hold a stronger competitive position against Jeju Air, which has operated as Korea's largest LCC, and may prompt capacity adjustments and route rationalisation across the sector.

The critical forward signals for investors are the Korean Fair Trade Commission's approval conditions, if any, and the December shareholder votes. Regulatory conditions restricting route concentration or requiring slot divestitures would limit the merged entity's competitive advantage. The unified Jin Air's initial route network announcement post-approval will be the earliest signal of whether the merger delivers the operational efficiency and network expansion that management is promising to shareholders.
