South Korea's low-cost airlines Jin Air and Air Busan have officially initiated a domestic codeshare agreement covering three major routes. This cooperation started on January 6, 2026, and includes flights between Seoul Gimpo and Busan, Jeju and Busan, as well as Jeju and Ulsan. Under this arrangement, Air Busan operates the flights, but Jin Air customers can purchase tickets using the 'LJ' flight code through Jin Air’s sales channels.
This development is a significant step towards broader industry integration, as the carriers prepare for a planned merger scheduled for early 2027. The consolidation will combine Jin Air, Air Busan, and Air Seoul under the auspices of Korean Air and Asiana Airlines, signaling a major restructuring within South Korea’s competitive aviation market.
The strategic alliance aims to optimize route networks and operational efficiencies among the participating airlines, which are all key players in the domestic low-cost segment. Industry analysts view this move as part of a wider trend toward consolidation among airlines seeking to strengthen their market position amid changing aviation dynamics.
The agreement underscores the evolving landscape of South Korean aviation, where collaborations and mergers are becoming increasingly common to adapt to competitive pressures and market demands.
