Overview
- Singapore Airlines said on Tuesday that about 46,000 of its booking records held on Amadeus' platform were accessed by an unauthorized third party.
- The exposed fields included passenger names, booking reference numbers (PNRs), travel itineraries and booking classes, and about 620 records may also include emails, phone numbers, travel‑document details and loyalty numbers.
- Amadeus has identified a vulnerability in a booking‑display environment and told carriers it implemented containment steps; the company and airlines say there is no evidence that payment card data was exposed or that bookings were altered.
- As a precaution SIA is contacting affected customers with upcoming travel to change booking reference numbers and has notified regulators while forensic teams work to refine the scope of the intrusion.
- The breach highlights systemic risk in travel technology because Amadeus centralizes reservation records for many airlines, and provisional exposure counts from other carriers are still being updated as investigations continue.
