San Francisco Airport (SFO) Transfer Guide

SFO sits about 21 km (13 miles) south of downtown San Francisco. On a good day, you can reach Union Square in 25 minutes. During rush hour — roughly 7 to 10 AM and 4 to 7 PM on weekdays — that can stretch to 50 minutes or more. BART (Bay Area Rapid Transit) takes about 30 minutes to reach downtown stations and runs independently of road traffic, making it reliable regardless of the time of day.

After clearing customs (international) or walking out of the gate area (domestic), you follow signs to your transport option. SFO has four terminals: International Terminal, Terminal 1, Terminal 2, and Terminal 3. All terminals connect via the AirTrain, a free automated people mover that loops continuously. The BART station is accessible from the International Terminal via AirTrain. Rideshare and taxi pickups are on the departures (upper) level of each terminal. If you have a pre-booked transfer, your driver will typically meet you in the arrivals hall or at a designated pickup zone — the confirmation email will specify exactly where.

BART is the most predictable option. It costs $11.15 one-way to downtown stations (Powell, Montgomery, Civic Center) as of 2026, or $22.30 round trip (bart.gov fare calculator). It runs 5 AM-midnight on weekdays, 6 AM-midnight on Saturdays, and 8 AM-midnight on Sundays. Trains come every 15-20 minutes. It works well if you have manageable luggage and are headed somewhere near a BART station.

Taxis are metered on the SFMTA tariff: $4.15 for the first 1/5 mile, $0.65 for each additional 1/5 mile, $0.65 per minute of waiting/slow-traffic time, plus a $6.00 SFO pickup fee (sfmta.com, current tariff). There is no official flat rate for this route — the meter runs the whole way, so the fare depends on traffic. Add 15-20% tip. Taxis queue outside arrivals on the lower level.

Rideshare (Uber/Lyft) shows you the fare before you confirm in the app. Pricing is dynamic and rises with demand, so it can be cheaper or pricier than a taxi depending on when you land — check the app for a live quote rather than assuming a fixed number. Pickup is on the departures level.

SamTrans buses are the budget option — $2.05 one-way with Clipper or $2.25 cash (samtrans.com/fares, 2026) — but routes are limited and slow.

Pre-booked private transfers offer a fixed price agreed before you travel, no surge risk, and a driver waiting with your name. Useful when you want certainty after a long flight — check the live quote for your route and dates rather than assuming a rate.

Getting to downtown San Francisco from SFO in 2026:

• BART: $11.15 per person one-way (bart.gov)
• SamTrans bus: $2.05 Clipper / $2.25 cash (samtrans.com)
• Taxi: metered on the SFMTA tariff ($4.15 flag drop + $0.65 per 1/5 mile + $6.00 SFO pickup fee) — roughly $50-70 for the ~13-mile ride into downtown depending on traffic, plus tip. No official flat rate applies; the meter runs the whole way.
• Rideshare and shared shuttle: dynamic, demand-based pricing — check the Uber/Lyft app or shuttle operator for a live quote rather than a fixed figure
• Private transfer: fixed price agreed at booking — check the live quote for your dates rather than assuming a rate

For destinations outside San Francisco — like Palo Alto, Oakland, or Napa Valley — expect meaningfully higher fares given the extra distance. Rideshare and private-transfer pricing to these areas is demand- and distance-based, so get a live quote for your specific trip rather than relying on a fixed estimate.

BART runs until midnight every day (bart.gov), and the last train from SFO departs shortly before that system-wide close — check the exact last-departure time on bart.gov's schedule for your travel date, since it varies slightly by day. If your flight lands late enough to miss it, your realistic options narrow to taxis, rideshare, or a pre-booked transfer. Taxis are always available at the curb, though you may wait 10-15 minutes at very late hours. Rideshare availability is generally fine, but demand-based pricing can push fares higher after midnight — check the app for a live quote. A pre-booked transfer guarantees someone is there regardless of when your flight actually touches down, which matters when delays push your arrival past 1 AM.

BART handles standard suitcases fine but gets awkward with strollers, car seats, and more than two large bags per person. There are no luggage racks on BART trains. Taxis at SFO are mostly sedans — fine for 2 adults and 2 bags, tight for anything more. If you are traveling with small children and need a car seat, rideshare drivers almost never have them. A pre-booked transfer lets you request a child seat, extra luggage space, or a larger vehicle in advance. For groups of 5+, a minivan transfer is usually cheaper per person than individual rideshares.

For pre-booked transfers, the standard meeting point is the arrivals hall of your terminal. Your driver will hold a sign with your name. Some services use the designated pickup zones on the outer curb — your confirmation will specify which. For rideshare, follow signs to the "Rideshare Pickup" area on the departures (upper) level. Taxis queue on the arrivals (lower) level of each terminal. If you are arriving internationally and clearing customs, allow at least 30-45 minutes before you reach the meeting point — experienced drivers know this and adjust.

Choose BART if: you are traveling light, heading to a downtown hotel near a BART station, and arriving during operating hours.

Choose a taxi or rideshare if: you want door-to-door convenience, have moderate luggage, and are comfortable with variable pricing.

Choose a pre-booked transfer if: you want a fixed price with no surprises, you are arriving late at night, traveling with family or heavy luggage, or heading somewhere outside the city center.

Choose SamTrans if: you are on a tight budget and have time to spare.
