In the news today, there has been a large-scale data breach at SITA that is impacting many airlines, since a *A carrier was a SITA customer and had FFP data from many partners stored there.

Main thread is in the *A forum here: SITA PSS frequent flyer data breach affecting all *A member airlines

It seems like AI was the carrier whose data was hacked, but numerous other carriers (BA, A3, AY, SQ, NZ, possibly more) have already sent out communications to their customers about potential impacts.

I've seen nothing yet from AC. Has anyone else?

Please use this thread to discuss potential impact on AC and AC customers specifically. For a broader discussion of the hack or impact on other airlines, see the above-linked thread or threads in other airline forums.
