Air Miles posts alert following thefts

More trouble for Air Miles.

The company has posted an alert on its website warning that criminals have stolen cash miles from some of its members.

It's not clear just how many members have been affected, or what the dollar value is.

While the company works to resolve the situation, it has temporarily removed the cash miles option for in-store purchases.

This comes a few weeks after Air Miles sent a note to its members apologizing for the controversy over changes to its expiration policy.

The rewards program angered members with its proposal to void unused Air Miles after five years, only to abandon that plan weeks before it was to take effect.
