IMPORTANT INFORMATION ABOUT YOUR KRISFLYER ACCOUNT
SITA, an information technology company providing passenger service systems, has informed Singapore Airlines of a data security breach involving their passenger service systems' (SITA PSS) servers. While Singapore Airlines is not a customer of the SITA PSS, another Star Alliance member airline is.

All Star Alliance member airlines provide a restricted set of frequent flyer programme data to the alliance, which is then sent on to other member airlines to reside in their passenger service systems. This data transfer is necessary to enable the verification of membership tier status, and to accord to member airlines' customers the relevant benefits while travelling.

As a result, SITA has access to the restricted set of frequent flyer programme data for all 26 Star Alliance member airlines including Singapore Airlines.

We are contacting you as your KrisFlyer data was impacted by this breach of the SITA PSS server. The information involved is limited to your KrisFlyer membership name, membership number and tier status, which is the full extent of the frequent flyer data set that Singapore Airlines shares with other Star Alliance member airlines for this data transfer.

Specifically, this data breach does not involve your membership password, credit card information, and other customer data such as itineraries, reservations, ticketing, passport numbers, and email addresses as SIA does not share this information with other Star Alliance member airlines for this data transfer. Your KrisFlyer miles balance was also not compromised.

We have recently been alerted that a Star Alliance partner has been impacted by a security data breach, involving some of our customers’ data as well as that of many other Star Alliance airlines.

The Star Alliance member airlines share minimal frequent flyer data between each other and limited third parties to ensure benefits can be used across different carriers, for example access to member lounges.

Unfortunately, some of your information has been involved in this data breach however, this is limited to your name, tier status and membership number. This is the full extent of frequent flyer data Air New Zealand shares with other Star Alliance member airlines.

This data breach does not include any member passwords, credit card information or other personal customer data such as itineraries, reservations, ticketing, passport numbers, email addresses or other contact information.
