It’s easy to tell the difference between happy and ticked off Air Miles collectors.

The happy ones are those, who did not redeem their points when the company that runs the loyalty points program announced come January, all unused miles earned before 2012 would have expired, and those miles earned from 2012 would also expire once they hit five years.

The upset collectors are the ones, who rushed out to redeem their points, thinking they’d lose them at the end of this year, only to hear Thursday the company’s changed its mind and cancelled its expiry policy.

The reason they’re not happy is because the company says those who cashed in their miles cannot reverse their purchases.

LoyaltyOne also estimates the reversal in policy will cost the company up to $250-million U.S. and that it plans to ”adjust” its offerings to collectors.

Now word yet what that means. 

LoyaltyOne’s also facing a proposed class-action lawsuit that came about following collector complaints.

A lawyer with the Calgary firm that filed the suit says, ”This reversal validates the complaints about Air Miles that we have received from the class members,” adding, while the proposed case will continue for now, lawyers will talk to class action members before making any final decisions.

And Monday, the Ontario Legislature is to vote on   private member’s bill from Beaches-East York MPP Arthur Potts, that would make it illegal for loyalty programs to make collectors points disappear without consent.
