As of August 1, 2008, the WestJet benefits, including the WestJet flight redemption benefit, will no longer be a feature of your card. Instead, as part of your new Gold Air Miles Reward Option you'll receive an exclusive 20% discount on all Air Miles flights. Now you'll have a greater choice and flexibility, with increased seat availability and more frequent flights.
So what does this mean? Up until now, holders of this BMO Westjet MasterCard could fly anywhere with WestJet in the high season for a max of 1600 points (900 for short flights). With the termination of this partnership, BMO Mosaik is now just offering a 20% discount on all partner airlines.
This is good for destinations WestJet doesn't service, but very bad for any destination they do.
For example. Charlottetown to Vancouver has a list price of 4800 points. Until August 1st, you can still book a flight with WestJet for 1600 points but after this, that same flight will now be only 20% lower at 3840 points—but with any airline.
It was good while it lasted.
Update: Just realized that on the rare short flight, it becomes cheaper. Charlottetown to Montreal (regular 1100/high season & 900/low season) drops from 900/800 points on WestJet only to 880/720 points on either WestJet or AirCanada.
