Incheon Airport Terminal Network Outage... 1,200 Wait as Chinese Airlines Suspend Check-In

Around 50 additional staff members to be deployed for on-site guidance

Passengers were inconvenienced after a failure occurred in the check-in system at an Incheon International Airport terminal.

Travelers who visited Terminal 2 of Incheon International Airport on the 23rd, a day before the Chuseok holiday, are heading to the departure hall. Incheon International Airport Corporation said it expects an average of 228,000 passengers per day, or 1.14 million in total, to use the airport over the five days from the 23rd to the 27th. This is a 4.8% increase from the previous record of 217,614 passengers per day during last year's Chuseok holiday. 2026.9.23. Photo by Kang Jinhyung

According to Incheon International Airport Corporation, a temporary disruption to the global check-in system occurred from 4:30 a.m. on Oct. 30 due to a network problem with U.S.-based Airlink (ARINC). The system has since been restored.

From noon, a network problem also disrupted TravelSky, the ticketing system used by three airlines - China Eastern Airlines, China Southern Airlines and Air China - leaving about 1,200 passengers waiting at the airport.

The three airlines are currently conducting check-ins manually, according to reports.

An Incheon International Airport Corporation official said, "We will minimize inconvenience for passengers facing long waits and delays by setting up passenger queues, increasing staffing for security screening in the departure hall, requesting additional screening staff from the Ministry of Justice, and deploying around 50 additional staff members to provide on-site guidance."
