Once you have arrived at San Francisco International Airport and gone through the security checkpoints, it is very easy to get around and between terminals. Terminals are within walking distance; however, it is more comfortable to take AirTrain, SFO’s fully automated people mover operating at the airport since 2003 24 hours a day. AirTrain is wheelchair accessible, and elevator service is available at all stations. It is possible to get on to AirTrain with your luggage cart that has hand brakes installed to keep them steady during the ride.
AirTrain has two lines: The red line connects SFO’s all terminals, garages, and BART Station, while the blue line connects the Rental Car Center with all the rest. Stations are located at all terminals. Look for the signs of AirTrain to find your station easily. Bicycles and service animals are allowed on the AirTrain while drinking, smoking, and eating is prohibited. The station departures are as frequent as 4 minutes.
Due to the reconstruction, part of Terminal 1 will be closed. However, if you need to get from the International Terminal to Terminal 3, you can opt for walking.
AirTrain is your only means to get to and from the Car Rental Center. If you need any additional help, ask friendly volunteers in the information booths. Do not leave the terminal without first finding out if you need to go through the security checkpoint again in case you need to come back.
