Qantas customer data exposed in cyber attack on reservation provider
Qantas, Australia’s national airline, reported a serious data security breach following a cyber attack on Amadeus, the company that provides its reservation technology.
In a statement shared with the media, Qantas revealed that its third-party booking technology provider, Amadeus, had notified the airline of a data breach affecting customer information handled through its systems from August 2023 to September 2026.
“We have been advised by global travel technology provider Amadeus that there has been unauthorised access to one of their systems.
“Amadeus advised the issue was contained in September and we’re working with them to understand the impact to any Qantas bookings. There is no impact to Qantas systems or databases which remain secure,” a Qantas spokesman said.
In October 2026, Amadeus, a Spain-based provider of travel technology solutions, announced a cybersecurity incident involving unauthorised access to its passenger booking infrastructure. The company discovered unusual activity across its reservation platform in September 2026 and subsequently alerted the airline partners concerned. The security breach potentially exposed passenger information stored and processed through Amadeus’ systems over the period from August 2023 to September 2026.
The compromised information included passengers’ names, booking reference numbers, flight dates, travel routes and other reservation-related details.
Another airlines company affected by the incident, Cathay Pacific said Amadeus has notified it that the breach affected around 53,000 bookings.
“Amadeus has confirmed that it has taken actions to contain the incident, including a password reset, and has implemented enhanced monitoring and detection capabilities on its systems. To date, Amadeus has not identified evidence that the affected data has been misused,” Cathay Pacific said.
Other airlines reported to have been affected by the breach include Malaysia Airlines, Japan Airlines, All Nippon Airways (ANA), and Korean Air, raising concerns across the international aviation industry.
