Korean Air and Asiana Airlines are migrating Asiana’s OZ flight codes to Korean Air’s KE flight-number system ahead of their full operational merger on 17 December 2026. The phased migration of bookings and flight numbers runs from 2 November to 3 December 2026 while the full flight-number transition across all schedules will wrap up by 1 July 2027. Starting 17 December 2026 Asiana Airlines will dissolve as a separate brand and operate under Korean Air.
Flights departing on or after 17 December will carry KE flight numbers though aircraft types and departure times generally remain unchanged. Passengers needing ticket changes or refunds must contact Asiana Airlines on or before 16 December 2026. From 17 December onward Korean Air will handle all customer service inquiries, changes and refunds.
The flight-number realignment covers hundreds of domestic and international services departing from both Seoul Incheon and Seoul Gimpo. Changes affect major long-haul hubs including Los Angeles, New York JFK, San Francisco and Sydney. Affected European destinations include London Heathrow, Paris Charles de Gaulle, Frankfurt, Rome Fiumicino, Milan Malpensa, Barcelona, Prague, Budapest, Istanbul, Almaty and Tashkent. Asiana Airlines will officially exit Star Alliance on 17 December 2026 as it integrates into Korean Air’s SkyTeam network.
