When waiting for the Red Line to take you to all the terminals, move all the way forward and avoid the crowd. Everyone huddles unnecessarily around the ticket machines and the other half is empty.
Very reasonably priced considering the alternative, taking a cab. If you dont know how to use the machine, ask for help! I'm tired of getting stuck behind these people and missing a train.
Signage after arriving on BART is terrible. Tips: 1) Head left up the stairs for all domestic flights; 2) There's only one train out of SFO, take Pittsburgh Baypoint and transfer to other lines in SF
As you arrive on BART, ride on the forward car for easy stroll into the International Terminal. Mid-train for AirTrain transfer and all other terminals.
