I tried them again recently because I had to get home fairly urgently so I just chose the cheapest flight. It was a bit of an ordeal because of the transfer through the Calgary hub which eventually got me to Vancouver by 11:30pm - but then I had to spend the night in Vancouver because I was too tired to make the drive to my home in Whistler (2hrs north of Vancouver). The only option would have me stay overnight in Calgary - which would not be fun to stay overnight between flights.
