Overview
- A network malfunction that began in the early morning disrupted ticketing and check-in across Terminals 1 and 2 and was declared fully resolved by the airport operator on Friday afternoon.
- The outage affected 13 airlines with the worst impact on China Southern, China Eastern and Air China, whose ticketing was effectively halted and later resumed around 5:20 p.m.
- The failure caused long lines, passenger protests and at least 35 to 38 delayed departures that left roughly 1,200 travelers waiting at counters during the day.
- Incheon International Airport Corp. deployed extra staff, allowed limited manual check-in for urgent departures and requested additional immigration support to ease terminal crowding while systems were down.
- The operator blamed a suspected glitch in U.S.-based ARINC's global network as a preliminary finding and officials say the attribution could prompt follow-up technical checks and reviews of vendor dependency.
