Last spring, Canadian airline WestJet revamped its WestJet Rewards program, introducing, among other things, the possibility of submitting an offer for an upgrade on WestJet flights using points, which is then either accepted or not by WestJet.

To promote this option, members will receive a bonus of 250 points in October if they submit an offer that is ultimately not accepted.

The strategy is hence clear: For every flight, you should submit the cheapest possible offer. Either you will actually get an upgrade at such a price with a bit of luck, or more likely, you will get 250 free points!
