Our WestJet credits are valid for 12-24 months, depending on when they were issued. And that date is only when they have to be used to purchase something. Travel dates can be after that. So the credits are valid for travel up to 34 months, as long as you buy your ticket well in advance, and assuming they will continue to release schedules 10 months in advance. I think it is fair. Our travel insurance will cover if they default before we can use the credits, too. Totally no risk to us, and WestJet is our favourite airline. Worst case we use the credits to visit family a few times. Best case we use it to go to London for the Iceland cruise.
