Westjet question using avion

I haven’t heard great things about avion. I can get 55000 avion points for new credit card and would like to fly from vancouver to calgary. Would it be better to use fixed rate schedule or convert to westjet rewards? Fyi as i travel solo the companion card on westjet card is worthless so not getting that. Just wondering if its worth getting it. I believe it would be worth 550 westjet rewards but not sure.
