This ultimate guide dives deep into a comparison of prices, travel times, and safety, helping you decide what's best for your budget, schedule, and peace of mind. Whether you're a solo traveler, family, or business visitor, we'll break it down based on the latest data to ensure a smooth journey.

Overview of San Francisco International Airport (SFO)

San Francisco International Airport (SFO) is the primary international airport serving the San Francisco Bay Area and the largest in Northern California. Located approximately 13 miles (21 km) south of downtown San Francisco in unincorporated San Mateo County, it is owned and operated by the City and County of San Francisco.

Terminal Layout

SFO is organized into a ring of four terminals connected by the AirTrain people mover.

  • Harvey Milk Terminal 1: Recently modernized, it serves Alaska, American, Delta, Frontier, JetBlue, and Southwest. It is world-renowned for its museum-quality art and sustainable design.

  • Terminal 2: The primary hub for Alaska (domestic) and Delta. It is famous for its "Zen" atmosphere and yoga room.

  • Terminal 3: The dedicated hub for United Airlines domestic flights. Note: United's international flights depart from International Terminal G.

  • International Terminal: Split into two boarding areas:

    • A-Gates: Most international carriers (e.g., Air France, Emirates, Cathay Pacific).

    • G-Gates: Primarily United (International) and Star Alliance partners like Lufthansa and Singapore Airlines.

Airport Internal Transportation: AirTrain

The SFO AirTrain is a free, 24/7 automated people mover that operates on two tracks. In 2026, navigating the AirTrain requires specific attention to the Terminal 3 closure.

Both lines run frequently (every 4–6 minutes) and are located on the Level 4 of the domestic terminals and the Mezzanine level of the International Terminal.

  • Red Line (Circular): Connects all terminals, terminal garages, the BART Station, and the Grand Hyatt at SFO. This is the fastest way to move between terminals.

  • Blue Line (Extended): Follows the same route as the Red Line but adds stops at the Rental Car Center and Long-Term Parking.

Tip: If you are heading to your car or a rental, ensure you are on the Blue Line. The Red Line does not stop at the Rental Car Center.

Unique Amenities

SFO distinguishes itself with "San Francisco-style" amenities:

  • SFO Museum: Rotating art and history exhibits throughout all terminals.

  • Yoga Rooms: Located in Terminals 1, 2, and 3.

  • SkyTerrace: An outdoor observation deck (pre-security) in the International Terminal with 180-degree views of the airfield.

  • Local Dining: You’ll find local favorites like Boudin Bakery, Napa Farms Market, and The Slanted Door rather than typical fast-food chains.
