Asiana Airlines to Exit Star Alliance in December 2026

Airlines will officially depart the Star Alliance network on December 16, 2026, concluding a 23-year membership just hours before its full integration into Korean Air.

The exit, announced in a Star Alliance press release, marks the final step in a long-anticipated shift in the South Korean aviation market. According to reporting by Travel Weekly, Korean Air acquired Asiana for $1.3 billion in December 2024. Korean Air is a founding member of the rival SkyTeam alliance.

Frequent flyer deadlines and transition details

Star Alliance has established specific cutoff dates for loyalty program members. Customers flying on Asiana Airlines-operated flights have until October 15, 2026, to earn miles in Star Alliance frequent flyer programs.

The final date to redeem miles for Star Alliance award tickets and upgrades on Asiana Airlines is December 16, 2026. This date also serves as the deadline for passengers to utilize Star Alliance Gold and Silver status benefits on Asiana flights.

In a statement regarding the transition, Star Alliance noted that the organization and Asiana Airlines will coordinate closely to maintain a seamless customer experience leading up to the departure. The alliance also thanked the carrier and its employees for their contributions since joining in 2003.

Post-exit operations at Incheon International Airport

Despite the loss of its South Korean member airline, Star Alliance will maintain a significant presence in Seoul. Following Asiana’s departure, 14 member airlines will continue to operate flights to and from Incheon International Airport (ICN).

The remaining Star Alliance carriers serving the airport include:

• Air Canada
• Air China
• Air India
• Air New Zealand
• Ethiopian Airlines
• EVA Air
• LOT Polish Airlines
• Lufthansa
• Shenzhen Airlines
• Singapore Airlines
• SWISS
• Thai Airways
• Turkish Airlines
• United Airlines

The Korean Air consolidation

The departure from Star Alliance is a direct consequence of the corporate merger between South Korea’s two largest airlines. Merger discussions began in 2020 and culminated in the December 2024 acquisition following extensive regulatory reviews across multiple international jurisdictions.

Travel Weekly reported that the boards of both airlines announced in May 2026 that the final consolidation would occur in December. The two carriers are scheduled to complete their integration on December 17, 2026, immediately following the Star Alliance exit at 23:59 Korea Standard Time (KST) the night prior.

AirPro News analysis

We view Asiana’s exit from Star Alliance as a major structural shift for the East Asian alliance landscape. SkyTeam will now dominate Incheon International Airport through the combined Korean Air entity. Star Alliance loses a dedicated hub carrier in a critical market, forcing its remaining 14 operators at Incheon to rely entirely on point-to-point traffic and their own respective hubs rather than regional feed from a local partner.
