I am curious, Westjet flys to Phoenix of all places but it does not fly to San Francisco, one of the major tourist and business destinations. Does anyone know why or if they have plans to go there in the near future to SFO, OAK or SJC?

I started flying AC on this route end of June and planes are mostly full and the gate agent says they make a lot of money on this route... I know if I don't book 14 or 21 days in advance and I want specific flights, the fare is often C$1000+ RT...
