Japan Airlines (JAL) confirmed that its systems have returned to normal after a Japan Airlines cyberattack caused disruptions earlier in the day. The incident affected both domestic and international flight operations, delaying flights and halting same-day ticket sales.
The disruption began at 7:24 a.m. on December 21, 2024, when JAL’s internal and external systems experienced malfunctions caused by a cyberattack. A router malfunction temporarily impacted operations, forcing the airline to suspend ticket sales for flights departing on the same day. Following the Japan Airlines cyberattack, the systems’ recovery was closely monitored.
Despite the temporary shutdown of its systems, JAL assured the public that no customer information was leaked during the incident. Additionally, the company confirmed it suffered no damage from computer viruses related to the Japan Airlines cyberattack.
Impact on Other Airlines
ANA Holdings, another major Japanese airline, reported no signs of cyberattacks on its systems during the incident affecting JAL. A spokesperson from ANA confirmed that its operations remained unaffected and proceeded as scheduled.
Around the same period, American Airlines faced a separate issue on December 24, 2024, when a technical glitch with network hardware temporarily grounded all its flights for an hour. The disruption affected thousands of passengers traveling on Christmas Eve but was unrelated to the Japan Airlines cyberattack.
JAL successfully addressed the router malfunction and resumed full operations by the end of the day. Same-day ticket sales for domestic and international flights also resumed without further complications. The airline has reiterated its commitment to system security and has taken measures to prevent similar incidents in the future, thereby mitigating the risk of another Japan Airlines cyberattack.
With operations now back to normal, JAL continues its investigation into the attack to ensure the safety and reliability of its services.
