SFO - YYC

Great experience on WestJet from SFO to YYC. (My experience at YYC wasn't as good, but that's for another review) The gate area is spacious, with lots of seating and electrical power. Boarding was pretty seamless, aircraft was in excellent shape, great crew, good food (in Business), and smooth flight. I wouldn't hesitate to take WestJet in/out of SFO again.
