About San Francisco International
United's primary transpacific gateway, and one of the few US airports where the train reaches the terminal door.
San Francisco International handled 54,532,613 passengers in 2025 across four terminals, seven concourses and 121 gates, laid out counterclockwise around a central terminal area. Harvey Milk Terminal 1 holds Boarding Areas B and C, Terminal 2 holds Boarding Area D, Terminal 3 holds Boarding Areas E and F, and the International Terminal holds Boarding Areas A and G.
United runs SFO as its primary transpacific gateway and its major maintenance base, and Alaska Airlines also hubs here. The result is a heavy long-haul departure profile, which means longer trips, longer parking stays, and more people leaving a car for two weeks rather than two days.
The thing that makes SFO unusual among big US airports is that the rail connection actually works. BART has run into the airport since June 2003, reaching downtown San Francisco, Oakland and the East Bay directly. That takes a real slice of demand out of the parking market and leaves it to drivers from the Peninsula, the South Bay and further out.
Getting to SFO
All the practical access info, by car, train, coach and otherwise.
The airport sits about 12 miles southeast of the city in unincorporated San Mateo County, on the Peninsula corridor between San Francisco and the South Bay.
BART runs directly into the airport, with service to downtown San Francisco, Oakland and the East Bay. The BART station is served by the AirTrain at the Garage G/BART stop.
SamTrans buses serve the airport, connecting the terminals with San Mateo County and the wider Peninsula.
The AirTrain people mover, open since 2003, is what ties the site together. The Red Line runs a clockwise loop around the central terminal area in about nine minutes, calling at the Grand Hyatt at SFO, Garage A, International Terminal A, Harvey Milk Terminal 1, Terminal 2, Terminal 3, International Terminal G and Garage G/BART. The Blue Line runs the same stations counterclockwise and then continues to West Field Road, the Rental Car Center and long-term parking, a 25 minute round trip.
How parking works at San Francisco International
The two central garages are Garage A and Garage G, both of them AirTrain stations in their own right. Garage A sits by International Terminal A and Garage G sits by International Terminal G alongside the BART station, so either one puts you a short AirTrain ride from any terminal.
Long-term parking is a separate structure out on the Blue Line, connected by a skybridge to level 5 of the parking building. It is the airport's own value option, and the trade is time: the Blue Line loop takes 25 minutes for a full circuit, so it is a different proposition from walking out of Garage A.
Because SFO's traffic skews long-haul, a large share of parking here is multi-week rather than multi-day. That is exactly the stay length where the price difference between a central garage and a value option compounds, so it pays to price the whole trip rather than the first night.
Tips travelers wish they'd known
- Work out your boarding area, not just your terminal. SFO is laid out counterclockwise and Harvey Milk Terminal 1 alone spans Boarding Areas B and C.
- The AirTrain Red Line is the fast one, a nine minute loop of the central terminal area. The Blue Line covers the same terminals but carries on to long-term parking and the Rental Car Center, so it takes longer.
- If you are on a two-week trip, compare total cost rather than daily rate. SFO's long-haul profile makes long stays normal here and the compounding is where the money is.
- Fog is a genuine scheduling factor at SFO, particularly in summer. It affects arrivals more than departures, but build in slack if you are connecting.
SFO questions, answered
The questions our 24/7 team gets asked most about flying from San Francisco International.
How early should I arrive at SFO?+
Two hours for domestic flights and three for international. Add time for the AirTrain if you are parking away from your terminal, and more again if you are coming from long-term parking on the Blue Line.
How do I get from parking to my terminal at SFO?+
By AirTrain. Garage A and Garage G are both AirTrain stations, and long-term parking connects to the Blue Line by a skybridge from level 5 of the structure.
What is the difference between the AirTrain Red and Blue lines?+
The Red Line is a nine minute clockwise loop of the central terminal area, calling at the terminals and both garages. The Blue Line runs counterclockwise through the same stations and then continues to West Field Road, the Rental Car Center and long-term parking.
Is SFO parking worth it when BART goes to the airport?+
It depends where you start. BART is direct and fast from San Francisco, Oakland and the East Bay. From much of the Peninsula, the South Bay and beyond, driving and parking is the practical option, and that is where SFO's parking demand comes from.
