I have two domestic flights to connect from in SFO tomorrow. Whilst the time is a little tight (52mins), there's not much I can do about the times apart from hope for a bit of luck. I'm flying united (SkyWest) from LAS to SFO arriving T1 I believe, and then connecting onto a United Hawaii flight (T3). I have no checked luggage, and hope to be checked in to both flights at Vegas with relevant paperwork. What's the fastest way to get from T1 to T3 in san fran? Airside? Landside? SkyTrain? Running across the carpark?
