Japan Airlines (JAL) experienced significant operational disruptions on Thursday, December 26, following a cyberattack-induced system malfunction. The airline temporarily suspended ticket sales for flights scheduled on the same day and reported delays across domestic and international routes.
System Malfunction and Cause Identified
JAL confirmed that the disruption stemmed from a malfunction in network equipment connecting the airline with its customers. The issue was traced to a faulty router, which was temporarily shut down to prevent further complications.
While efforts to restore normal operations were ongoing at the time of this report, flight safety remained unaffected, according to the airline.
Apology and Passenger Communication
JAL issued an apology to affected passengers for the inconvenience caused and assured continuous updates as the situation evolves. The cyberattack coincided with Japan’s peak winter travel season, amplifying the impact on travelers amid year-end holidays.
Market Impact and Financial Fallout
The airline’s shares dropped by 2.5% during trading on Thursday, marking their sharpest intraday decline since early October. This financial hit reflects investor concerns over the operational and reputational impact of the cyber incident.
Founded in 1951, Japan Airlines operates out of Tokyo’s Narita and Haneda airports, along with Osaka’s Kansai and Itami airports. The airline transitioned from a state-owned entity to full privatization in 1987 and remains a cornerstone of Japan’s aviation industry.

Global Context and Similar Incidents
The JAL incident follows a similar disruption faced by American Airlines Group Inc. on Christmas Eve. A technical glitch involving DXC Technology Co., a third-party vendor managing flight-operating systems, caused a one-hour ground stop for all US flights.
These incidents highlight the growing vulnerabilities in aviation technology infrastructure and the rising frequency of cyberattacks targeting critical industries.
Looking Ahead
Japan Airlines is working to fully restore its systems and prevent future disruptions. Cybersecurity remains a growing priority for global airlines as they handle critical customer data and operational networks.
Passengers are advised to stay updated through official airline channels and plan their travel schedules accordingly.
