A check-in system malfunction at Incheon International Airport on Friday, October 30, caused major boarding delays, affecting passengers on 35 flights. The problem began at 4:30 a.m. in an airline network connection and was fully resolved by Friday afternoon, according to the Incheon International Airport Corporation. Yonhap reports the disruption caused widespread delays in departure procedures, with ticketing services for three airlines at Terminal 1 resuming after the system was restored. Korean news outlets, including KBS World and Korea Times, focused on the operational impact and the airport operator's confirmation of the restoration, rather than on individual passenger experiences.
