The airline joins Cathay Pacific Airways, Japan Airlines, South Korea’s Asiana Airlines and others that have reported customer data was compromised in the Amadeus breach. Malaysia Airlines also said some of its customer information may have been affected.
Singapore’s flag carrier said that data exposed by the breach included customers’ names, booking reference numbers, travel itineraries and booking classes.
Information including email addresses, phone numbers, travel document details, and KrisFlyer membership numbers may also have been accessed for about 620 booking records, the company said.
It added that Amadeus confirmed that bank account or credit card information had not been leaked and bookings were not modified.
Singapore Airlines said it was reaching out to affected customers with upcoming travel plans to change their booking reference numbers as a precaution.
The airline also confirmed that its IT systems were not breached.
Amadeus said it had become aware of a vulnerability affecting a travel booking display environment but did not respond to a question on how many customers’ data were affected.
In recent days, Cathay Pacific and Japan Airlines reported that the breach had affected data involving 53,000 bookings and 92,000 customers, respectively
