What You Can Bring on AirTrain

Airport Luggage Carts

SFO installed hand brakes on all airport luggage carts to keep them steady during travel. For your safety, please set the brake once you board an AirTrain car and do not take carts onto escalators.

Animals

Service animals and animals being shipped are permitted on AirTrain. Animals being shipped must be crated at all times.

Bicycles

Bicycles are allowed on AirTrain. Please be courteous of other passengers.

Prohibited Activity

Eating, drinking and smoking are not allowed on AirTrain.

Shuttles to Long-Term Parking Facility

SFO's long-term parking facility and shuttle buses operate 24 hours a day. Frequent shuttle service runs every 5 minutes to 15 minutes. Electronic displays in the garage let you know when the next bus is due.

Shuttle Schedule

SFO buses have priority loading zones at each terminal for quick passenger access. Customers parked in Lot D- Long-Term Overflow Parking, please take the Lot D shuttle to return to the lot.

During peak travel periods the Airport provides baggage loading assistance in the garage and at each terminal stop.

Walking the Airport

Due to construction, a portion of Terminal 1 is closed on both levels.  The best way to get from the International Terminal to Terminal 1 Boarding Areas A and B (Gates 20 – 48), or Terminal 2 (Gates 50 – 59) is via AirTrain.  The best way to get from the International Terminal to Terminal 3 (Gates 60 – 90 United) is by walking.  However, AirTrain is your only means to and from the Rental Car Center.

Information Booths

Information booths, staffed with friendly volunteers, are located throughout the terminals. Please view the Information Booths map for exact locations. Language assistance is available.
