WHY would UA operate all Asia flights from SFO? All those people flying just to Tokyo from JFK, ORD, & LAX would switch airlines. I would if I was booked on UA. SYD service from LAX makes much more sense too, I know UA operates SFO-SYD service but that is really supported by the hub no so much SFO originating traffic. If this rumor is true we should operate all service to LHR from JFK.
