The San Francisco International Airport (SFO) operates an on-campus automated people-mover (AirTrain). AirTrain operates two routes, the Blue Line and the Red Line. The Blue Line makes it easy to connect from the Rental Car Center to and from all terminals, Domestic & International Parking Garages, and the Grand Hyatt at SFO. The Red Line runs in a continual loop connecting all terminals, Domestic & International Parking Garages, and the Grand Hyatt at SFO.
SFO also offers bus service connecting the long-term parking lots to all terminals and limited shuttle bus service connecting International Terminal G to the San Francisco Bay Ferries in Oyster Point.
