What San Francisco International Airport looks like and how to move through it

San Francisco International Airport (SFO) sits on the peninsula south of the city, about 13 miles from downtown. The airport has four terminals — Domestic, International, and two satellite terminals connected by an automated people mover. Most domestic flights leave from the Domestic Terminal. International flights use the International Terminal, though some airlines also use the Domestic Terminal for international routes.

Once you land, you'll move through baggage claim, then ground transportation. The layout is straightforward: each terminal has its own baggage claim level, and ground transportation (rental cars, taxis, rideshare) is one level below that. Signs in English and multiple languages direct you to each section.

The people mover, called the AirTrain, connects all terminals and the BART station (Bay Area Rapid Transit — the regional train system). It runs 24 hours and costs $10.15 per trip. If you're renting a car or taking a taxi, you don't need the AirTrain; you'll go directly to the ground transportation level.

Key Takeaways

  • SFO has four terminals: Domestic, International, and two satellites; the AirTrain people mover connects them all and costs $10.15 per trip.
  • BART (Bay Area Rapid Transit) is the cheapest way into the city at around $10, takes 30 minutes to downtown, and the station is one AirTrain ride from any terminal.
  • Rideshare pickup (Uber, Lyft) happens on designated levels; rental car counters are in each terminal, and taxis queue at ground transportation.
  • TSA PreCheck and Clear are available at SFO if you want to move through security faster, though you must enroll before your trip.
  • Parking at SFO is expensive (around $30 to $40 per day depending on lot type), so BART or rideshare is usually cheaper for getting to the city.

Getting from the airport into San Francisco or the Bay Area

BART is the fastest and cheapest way into downtown San Francisco. The BART station is inside the airport, accessible by AirTrain from any terminal. A one-way ticket to downtown costs around $10 and takes about 30 minutes. BART runs from early morning until midnight, with trains every 15 to 20 minutes during the day.

Rideshare (Uber, Lyft) is more expensive but door-to-door. Pickup zones are on the upper levels of each terminal, clearly marked. Prices vary by time of day and demand; expect $20 to $50 for a ride to downtown during normal hours, more during peak times.

Taxis queue at the ground transportation level of each terminal. You take a numbered ticket and wait for your turn. Taxi fares to downtown are metered and typically run $35 to $50 depending on traffic.

Rental cars have counters in each terminal. You'll need a driver's license, credit card, and proof of insurance (your own or the rental company's). Parking at SFO itself costs $30 to $40 per day, so if you're staying in the city, BART is usually cheaper than renting a car and paying for parking.

What to know about security screening and TSA PreCheck

Security screening at SFO happens on the upper level of each terminal. Standard screening lines move fairly quickly, but peak hours (early morning, late afternoon) can have waits of 30 minutes or more. TSA recommends arriving two hours before a domestic flight and three hours before an international flight.

TSA PreCheck is a program that lets you go through a faster security line. You keep your shoes, belt, and light jacket on, and you can leave your laptop and liquids in your bag. TSA PreCheck costs $78 to $85 for five years and requires an in-person appointment at an enrollment center. You must enroll before your trip — you cannot sign up at the airport.

Clear is a separate service that uses biometric scanning (your eyes and fingerprints) to move you to the front of the security line. It costs around $179 per year and works at SFO. Like TSA PreCheck, you must enroll before you travel.

If you don't have either program, the standard security line is your only option. Have your ID and boarding pass ready, remove your shoes and belt, and put your laptop and liquids in a separate bin.

Renting a car at SFO

Rental car counters are located in each terminal on the ground level or one level below baggage claim. Major companies at SFO include Enterprise, Hertz, Budget, Avis, and National. You can reserve a car online before you arrive, which usually saves money.

To rent a car, you'll need a valid driver's license, a credit card in your name, and proof of insurance. Your personal auto insurance may cover rental cars, or you can buy insurance from the rental company. Ask your insurance company before you travel.

Rental car rates vary widely by company, car type, and dates. Prices are usually higher if you book at the counter than if you reserve online. The rental car facility is separate from the terminals; a shuttle bus takes you there from the ground transportation level.

Parking at SFO if you're driving to the airport

SFO has several parking options: short-term parking (for drop-offs and quick stops), daily parking, and long-term parking. Short-term parking is the most expensive at around $3 per 15 minutes. Daily parking runs $30 to $40 per day depending on the lot. Long-term parking is cheaper per day but requires a shuttle to the terminals.

You can reserve parking online through the SFO website before you arrive, which sometimes offers discounts. If you're parking for more than a few days, long-term parking is usually cheaper than daily parking.

If someone is dropping you off, use the departures level of your terminal. You can stay there for up to 10 minutes free; after that, short-term parking rates explore.

Amenities and services inside the terminals

All four terminals have restaurants, cafes, and shops. The Domestic and International terminals have more options than the satellite terminals. If you have a long layover, you can find food, books, electronics, and travel items in most terminals.

Free WiFi is available throughout the airport. You don't need to register; just select the SFO network and open your browser.

If you need to shower, rest, or work during a layover, SFO has a paid rest area called the SFO Yoga and Meditation Room (free) and paid nap pods in some terminals. Check the SFO website or ask at an information desk for current locations.

Currency exchange and ATMs are available in each terminal. ATMs charge a fee, usually $2 to $3, so withdrawing larger amounts at once is cheaper than multiple small withdrawals.

Connecting flights and layovers at SFO

If you're connecting between two flights at SFO, the time you need depends on whether both flights are domestic, both are international, or one is each. Domestic to domestic connections usually need 45 minutes to an hour. Domestic to international or international to domestic needs 90 minutes to two hours because you'll go through security again or customs.

International to international connections can sometimes avoid re-screening if both flights are in the International Terminal, but this varies by airline and destination. Ask your airline when you book or check your itinerary.

If your connection is tight and your first flight is delayed, ask the flight attendant before you land. SFO ground staff can sometimes hold a connecting flight for passengers with tight connections, but this is not may provide.

The AirTrain connects all terminals, so if you need to change terminals, take the AirTrain. It runs every few minutes and takes 5 to 15 minutes depending on which terminals you're connecting between.

Frequently Asked Questions

How early should I arrive at SFO?

What if I miss my flight?

Contact your airline when ready. Some airlines will rebook you on the next available flight at no charge if the delay was their fault. If the delay was yours, you may have to buy a new ticket. Check your airline's policy before you travel.
