GoKawiilAmadeus breach exposes data of 92,000 Japan Airlines customers
Japan Airlines disclosed that unauthorized access to Amadeus's Passenger Service System, which handles reservations and check-in, occurred between August 2023 and September 2026 and exposed data on roughly 92,000 customers. For most, exposed details included reservation codes, names, flight dates, routes and travel class, while about 2,000 customers also had contact details, passport numbers, frequent flyer numbers and ticket information exposed. JAL said credit card numbers and passwords were not compromised and that Amadeus has since applied security fixes, with flight operations unaffected.
