I would appreciate your thoughts on an upcomeng trip relating to connection times at SFO. I am flying VS, SFO-LHR-SFO later this month with an arrival time of 205pm into SFO from LHR. I am flying DFW-SFO-DFW on UA(separate ticket). I booked both online with the UA SFO-DFW departing SFO at 647pm...plenty of time to connect. UA just notified me they put me on a 445pm departure to DFW via DEN...which pissed me off as I wanted the nonstop. I cannot pull up the nonstop I was booked on so I assume the flight was dropped in a schedule change. My fare dropped $98.20...any chance I can get a refund without paying at $100 change fee? Is 2H40M enough time to clear customs and get to UA for the SFO-DFW flight. Thanks very much.
