Japan Airlines (JAL) customers experienced dozens of flight delays and cancellations on Thursday after an early morning cyberattack caused its systems to malfunction.
The Tokyo-based airline announced that at 7:24 a.m. local time, a disruption to its “network equipment” affected communications between “internal and external systems.”
JAL reported it had to temporarily shut down a network router, impacting domestic and international flights, as well as same-day ticket sales.
The malfunction caused flight delays and cancellations for most of the day, also forcing the airline carrier to suspend its "Airport Standby" service and "Same-Day Upgrade" procedures via the JAL website and JAL app.
“This failure is caused by receiving a large amount of data from an external source," JAL said in a post on its website.
No customer data was compromised during the incident, and there was no damage to the system from any malware, JAL said.
Additionally, JAL stressed that the disruption had “no impact on safe operations.”
By 8:56 a.m., JAL posted on X that it had “identified the cause of the problem and took action,” restoring its network communications by 7:45 p.m. Japan Standard Time (JST) and resuming online ticket sales.
American Airlines briefly grounded all flights for an hour this week, disrupting travel for thousands on Christmas Eve, due to a technical glitch involving network hardware.
