Japan Airlines (JAL) announced on Thursday that its systems were fully restored after a cyberattack earlier in the day disrupted domestic and international flights. The incident affected internal and external systems, prompting the airline to suspend same-day ticket sales temporarily.
The attack began at 7:24 a.m., causing malfunctions linked to a router, which JAL identified and resolved by shutting it down. Ticket sales for flights departing on Thursday resumed once the issue was addressed.
JAL confirmed that no customer data was leaked during the incident and reported no damage from computer viruses. Meanwhile, ANA Holdings, Japan’s other major airline, stated that its systems were unaffected by the cyberattack.
The disruption at JAL follows a similar incident earlier this week when American Airlines briefly grounded all flights for an hour on Christmas Eve due to a technical issue involving network hardware, affecting thousands of travelers.
