Japan Airlines (JAL) announced on Thursday that its systems have returned to normal following a cyberattack that disrupted domestic and international flights earlier in the day. The attack, which began at 7:24 a.m., caused malfunctions in internal and external systems, forcing the airline to suspend same-day ticket sales temporarily. The issue was resolved after shutting down a malfunctioning router.
JAL confirmed that no customer data was leaked and there was no damage from computer viruses. The company resumed ticket sales for flights departing on Thursday once the systems stabilised. Meanwhile, ANA Holdings, Japan’s other major airline, reported no signs of a similar attack on its operations.
The incident comes shortly after American Airlines briefly grounded all flights on Christmas Eve due to a network hardware glitch, highlighting ongoing challenges airlines face with system vulnerabilities during peak travel periods.
