The attack began at 7.24 am and affected the company's internal and external systems, JAL said.

The company said it temporarily shut down a router that was causing system malfunctions and also suspended ticket sales for flights departing on Thursday.

ANA Holdings, Japan's other major air carrier, saw no signs of an attack on its systems, a spokesperson said.

Earlier this week, American Airlines briefly grounded all flights for an hour, disrupting travel for thousands on Christmas Eve, due to a technical glitch involving its network hardware.
