I'm flying into SFO that day for an MR, but on..... *gasp* NW! Haha! I'm arriving around 11:30am, and flying out around 9:30pm. Is it possible at SFO to come over to the United side if I have a NW ticket? I'm not sure what my plan for the day is, probably just bumming around the city!! Maybe I'll run into some of you!
