Japan Airlines (JAL) announced that its systems have returned to normal after a cyberattack disrupted operations on Thursday, affecting domestic and international flights. The incident, which began at 7:24 a.m., caused malfunctions in internal and external systems.

JAL identified the issue as a faulty router and promptly shut it down, temporarily suspending same-day ticket sales for flights departing on the day of the attack.

Despite the disruption, JAL confirmed that no customer information was leaked and no damage from computer viruses occurred. Ticket sales resumed shortly after the systems were restored.
In contrast, ANA Holdings, Japan's other major airline, reported no signs of any attacks on its systems, according to a company spokesperson.

Meanwhile, American Airlines faced a separate technical issue this week, grounding all flights for an hour on Christmas Eve. The disruption, attributed to a network hardware glitch, caused significant delays for thousands of travelers during the busy holiday season.

The incidents highlight the critical importance of robust cybersecurity and technical infrastructure for airlines, especially during peak travel periods.
