Japan’s other major airline, ANA Holdings, reported no signs of cyberattacks affecting its systems, according to a company spokesperson.
This incident comes just days after American Airlines faced a significant disruption on Christmas Eve. A technical glitch involving network hardware led to the temporary grounding of all flights for an hour, affecting thousands of travelers.
Cyberattacks and technical failures highlight growing vulnerabilities in the aviation industry’s reliance on digital infrastructure.
