Hong Kong's Cathay Pacific Airways has said it is among a growing list of global airlines affected by a data breach at a major software provider, Amadeus IT Group. In a statement on Friday (October 30), the airline said around 53,000 bookings were affected by unauthorised access to reservation data held by Amadeus between August 2023 and September 2026, according to a Bloomberg report carried by The Star.
What data was involved
Cathay said most of the affected records contained booking references, passenger names and flight details. A smaller subset potentially included email addresses, phone contacts and travel document information. The airline said the incident is under investigation and is not affecting its own systems or operations.
Other airlines hit
The report said the breach has touched a number of major carriers. Japan Airlines has said about 92,000 customer records were exposed in a cyberattack, while ANA Holdings said information of up to 37,800 passengers was leaked. Korean Air Lines and Germany's Condor have also said their data was affected. It remains unclear whether more airlines will come forward, since Amadeus software is widely used across the global aviation industry. Deutsche Lufthansa, which entered a partnership with Amadeus this year, had not immediately responded to a request for comment at the time of the report.
Why this breach matters
Airlines rely on a small number of technology vendors to handle bookings, check-in and passenger records. When one provider is compromised, the impact can spread to many airlines at once, even if each airline's own network remains secure. The long period covered by the unauthorised access, nearly three years according to Cathay's statement, also highlights how difficult it can be to detect this kind of intrusion.
Advice for travellers
Passengers who have flown with affected airlines should watch for phishing messages that use real booking details to appear convincing. Avoid clicking links in unexpected messages, and verify any request for information through the airline's official channels.
