Singapore Airlines Says Amadeus Incident May Affect 46,000 Booking Records

Singapore, 4 November 2026 – Singapore Airlines Limited said on 3 November that about 46,000 booking records may have been affected by a cybersecurity incident involving reservation-technology provider Amadeus. Additional information, including travel-document details and loyalty-programme identifiers, may have been accessed for approximately 620 records. The airline said its own information-technology systems were not breached.

For Asian airlines and corporate travel customers, the disclosure shows how a supplier incident can expose passenger information without compromising a carrier’s internal network. The figures count booking records, not necessarily unique people. They also describe different levels of potential exposure, rather than evidence that every affected record contained all the personal fields listed.
