[Alpha Biz= Reporter Kim Sangjin] Due to a global IT crisis that once paralyzed three domestic low-cost carriers (LCCs), their IT services have now been restored, and their international flights are operating normally.

According to the Ministry of Land, Infrastructure, and Transport and the aviation industry on the 21st, the ticketing and reservation systems of Jeju Air, Eastar Jet, and Air Premia, which experienced IT system errors, have been fully restored and are currently operating normally since the morning of the previous day.

Since last night, no direct delays or cancellations related to the LCCs due to Microsoft (MS) errors have been reported.

The system errors affecting 12 foreign airlines, including Delta Air Lines, Tigerair, and Cebu Pacific, operating at domestic airports, have also been gradually resolved, and their ticketing systems are now operating normally.

During the two days of system errors from the 19th to the 20th, domestic airports experienced multiple flight delays and cancellations.

According to the aviation industry, during this period, 221 flights were delayed at Incheon International Airport (63 flights) and other domestic airports such as Gimpo and Jeju (158 flights).

A total of 10 domestic flight cancellations were reported—4 on the 19th and 6 on the 20th.

The MS cloud service outage at 3:30 p.m. on the 19th led to significant confusion, with domestic airlines initially having to process check-ins manually at the airport.

Apart from the three LCCs affected by the system errors, other domestic airlines and airports, including Incheon International Airport, have their own cloud systems and thus experienced no disruption in flight operations.
