So again, I think all you are doing is trying to play the system as you want the AC flight and will miss a connection to get it hoping UA gives it for free. So there re lots of cheap UA options BUR-SFO-YVR with lots of different connection times you could easily make. Don't know why the AC flight is so important to you for an hour and a half flight.
