The Korea Fair Trade Commission approved Korean Air’s mileage integration plan for Asiana Airlines, clearing the last major regulatory hurdle before the carriers become a single legal entity on Dec. 17, 2026. Asiana miles will be managed separately for 10 years, while customers may convert their full balances to Korean Air SKYPASS miles at a 1:1 ratio for flight-earned miles and 1:0.82 for partner miles. Korean Air must preserve award-seat availability on major long-haul routes and report peak-season supply annually to a compliance committee. The airline is also pursuing an air operator certificate and overseas flight approvals for the combined company, which is planned to have 230 aircraft, more than 23 trillion won ($16.5 billion) in annual revenue and 28,000 employees.
