Here is what Michael McAdam has to say about the flight:
I naively wondered why my travel agent could not book me on Air Canada from YVR to SFO. The United flight, leaving five minutes later, however, was wide open. And then I flew United and knew why. The seat itself is adequate. The overhead screens, however, were not functional, a frequent woe when flying UA. (This is one of their MODERN aircraft??) All in all fine for a 2.5 hour trip, but sevice would certainly have been more attentive on AC and somehow I get the feeling that I could have watched a movie, as well.
