Korean Air estimates the cost of integrating Asiana Airlines could reach up to 1 trillion won. The airline projects that synergy effects from the merger will offset these expenses by the end of 2028.

The successful integration of Asiana Airlines by Korean Air is crucial for the future financial health and global competitiveness of both carriers, impacting passengers, employees, and the broader aviation industry in South Korea.
Korean Air Co. announced on Friday that the integration of Asiana Airlines Inc. could incur costs of up to 1 trillion South Korean won (approximately US$654.02 million). The airline projects that the synergy effects resulting from the merger will offset these expenses, potentially as early as the end of 2028.
During an investor relations session in Seoul, Korean Air detailed that its post-merger integration (PMI) strategy estimates costs ranging from 900 billion to 1 trillion won. Conversely, the annual synergy effects are anticipated to reach around 300 billion won. Park Hee-don, a senior vice president at Korean Air, expressed optimism that these synergy effects could surpass the initial projections, stating, "If things go well, we believe the integration costs could be fully offset sometime between the end of 2028 and early 2029."
The airline plans to finalize the launch of the integrated carrier by December 17, with the ambition of becoming a global top 10 airline. The combined entity is expected to operate 230 aircraft and generate 23 trillion won in annual revenue.
Regarding the integration of the two airlines' mileage programs, Korean Air indicated its hope for a swift finalization process, ideally before its shareholders' meeting scheduled for August.
