Japan Airlines reported a cyberattack on Thursday that caused delays to domestic and international flights but later said it had found and addressed the cause.
“We have identified the cause and scope of the malfunction, and the system has been restored,” said the airline, Japan’s second biggest after All Nippon Airways (ANA).
The “large data attack” did not leak any customer information and safety was unaffected, Japan Airlines (JAL) said in a post on social media platform X.
Ticket sales for domestic and international flights departing on Thursday were suspended during the incident but have now resumed, JAL said.
Although the cyberattack did not cause major disruption, the airline earlier said that 24 domestic flights had been delayed by more than half an hour.
Problems with the carrier’s baggage check-in system caused delays at several Japanese airports, local media said.
JAL shares fell as much as 2.5% in morning trade after the news emerged, before recovering. Its stocks were down 0.2% in the afternoon.
