Published on January 7, 2026

Seoul’s airports have recently experienced a wave of flight disruptions, affecting both domestic and international travelers. A total of 10 flights were cancelled, impacting key destinations including Jeju, Gimpo, Atlanta, and Singapore. The latest incidents involve Gimpo International Airport, Jeju International Airport, and Incheon International Airport, with multiple airlines forced to cancel flights across major routes. Travelers are feeling the impact as schedules are thrown off and plans disrupted.

Summary of All Cancellations

Total cancellations: 10
Affected destinations: Jeju, Gimpo, Atlanta, Singapore

Domestic Routes Hit Hard at Gimpo and Jeju

Domestic travel between Seoul and Jeju has been particularly affected. The busy connection between Gimpo International Airport and Jeju International Airport saw several cancellations, causing frustration for commuters, tourists, and business travelers alike.

Gimpo Airport Disruptions

• ASV905 to Jeju, scheduled for 2:30 PM KST on Wednesday, was cancelled.
• ASV907 to Jeju, scheduled for 6:40 PM KST on Wednesday, was also cancelled.

These cancellations removed key options for passengers traveling from Seoul to Jeju in the afternoon and evening, a peak period for short-haul flights.

Jeju Airport Delays

The return flights from Jeju to Seoul mirrored the disruptions:

• ASV906 to Gimpo, scheduled for 4:30 PM KST on Wednesday, was cancelled.
• ASV908 to Gimpo, scheduled for 8:40 PM KST on Wednesday, was cancelled as well.

Passengers on the Jeju-Seoul corridor now face rescheduling difficulties, highlighting the vulnerability of heavily trafficked domestic routes to operational issues. These domestic flight disruptions emphasize the need for travelers to plan alternative options or monitor airline updates closely.

International Flights Impacted at Incheon

While domestic routes took the brunt of cancellations, Incheon International Airport experienced its share of international flight delays, affecting long-haul services. Delta Airlines reported multiple cancellations to both the United States and Singapore:

• DAL9926 to Hartsfield-Jackson International (Atlanta) at 11:00 AM KST on Wednesday
• DAL26 to Hartsfield-Jackson International (Atlanta) at 7:25 PM KST on Tuesday
• DAL9936 to Paya Lebar Air Base (Singapore) at 9:00 AM KST on Thursday
• DAL9961 to Paya Lebar Air Base (Singapore) at 10:29 AM KST on Thursday

These cancellations not only affect travelers but also have ripple effects on connecting flights, airport operations, and logistical planning. The disruptions highlight the complexity of coordinating international flights across multiple time zones and operational requirements.

Patterns and Causes of Disruptions

Analyzing the cancellations reveals distinct patterns:

• Domestic flights were primarily affected on the Gimpo-Jeju route with Asiana Airlines
• International flights impacted by Delta Airlines included long-haul services to Atlanta and Singapore
• Both afternoon and evening slots were affected, indicating potential operational bottlenecks rather than isolated incidents

Although airlines have not officially stated the exact reasons for the cancellations, possible factors include:

• Aircraft availability and scheduling issues
• Crew assignments and duty limits
• Air traffic management constraints
• Operational challenges due to weather or technical factors

Passenger Impact and Airline Response

The consequences for travelers are significant:

• Seoul flight cancellations have disrupted travel plans for domestic commuters, tourists, and international passengers
• Passengers may need to reschedule flights, adjust itineraries, or seek refunds
• Airlines generally offer rebooking options and, in some cases, compensation for affected passengers

For domestic travelers, the Gimpo Airport disruptions and Jeju Airport delays create hurdles for short-haul connections, often requiring same-day alternatives that may be limited. International travelers face broader complications, as Incheon Airport cancellations and subsequent international flight delays can affect connecting flights and onward travel.

Tips for Travelers

Travelers navigating Seoul airports amid these cancellations should consider the following:

• Monitor airline notifications and official airport updates
• Allow extra time for connections and transfers
• Be prepared to adjust schedules or consider alternative travel dates
• Keep documentation for cancelled flights to claim potential compensation

Conclusion

The recent wave of Seoul flight cancellations illustrates the challenges of managing both domestic and international air travel. From the domestic flight disruptions on the Gimpo-Jeju corridor to long-haul international flight delays from Incheon, passengers must remain vigilant and adaptable. Airlines and airports continue to coordinate solutions, but the incidents serve as a reminder of the importance of contingency planning in modern air travel.

Travelers should stay informed and flexible, as disruptions on high-traffic routes like Gimpo-Jeju and international hubs like Incheon may continue to affect schedules. Seoul flight cancellations underscore the interconnected nature of air travel and the need for proactive planning to minimize inconvenience.
