San Francisco Airport: Home to a Real, Accredited Museum Inside the Terminals

Getting there, at a glance

Amenities, at a glance

San Francisco International Airport (IATA: SFO) is one of United Airlines’ largest hubs and a major gateway between the United States and Asia-Pacific, with more than 50 million passengers a year. It sits about 21 km south of downtown San Francisco.

Overview

SFO operates four terminals and holds a genuinely distinctive credential: SFO Museum is the first and only US airport museum accredited by the American Alliance of Museums, with rotating art and cultural exhibitions spread throughout the terminal buildings — a real curated collection, not just decorative airport art. As a major United Airlines hub, SFO also anchors an extensive network across the Pacific to Asia and Oceania. The airport’s own air traffic statistics put 2024 volume at 52.29 million passengers, with international traffic to Asia and the Middle East growing especially fast.

Terminals

• Terminals 1–3: Handle domestic United Airlines flights and other domestic carriers.
• International Terminal: Handles all international departures and arrivals, including United’s extensive transpacific network.

Airlines

United Airlines operates one of its largest hubs at SFO, with an extensive domestic network across the US alongside a major transpacific route network to Asia and Oceania that leverages San Francisco’s West Coast position. That concentration makes SFO one of the most useful US gateways for travel to and from Asia-Pacific.

Getting There

• BART: $10.20, a direct rail line to downtown San Francisco in about 30 minutes — fast, reliable, and unaffected by traffic.
• Taxi: Typically $60–75 to the city, about 25–35 minutes depending on traffic, with flat rates varying by destination.
• Uber / Lyft: Generally comparable in price to a taxi, about 25–35 minutes.

Prices above are approximate and subject to change — always check current fares with BART or your rideshare app.

Security and Passport Control Wait Times

• Domestic flights: Security only. Typically 15–25 minutes during off-peak hours, up to 30–45 minutes during busy periods.
• International flights: Security plus passport control on arrival. Typically 25–40 minutes during off-peak hours, up to 45–65 minutes during peak international departure banks.
• SFO handles a very high volume of both domestic connecting traffic and international departures — budget extra time during United’s peak banks.

Parking

All four terminal areas have adjacent short- and long-stay parking, with clear signage. Booking online ahead of arrival is cheaper than the walk-up rate.

Wifi

Free, unlimited wifi is available throughout the airport with no time limit.

Best Times to Arrive

• Domestic flights: Arrive 2 hours before departure.
• International flights: Arrive 3 hours before departure, especially during United’s peak transpacific departure banks.
• Given SFO’s size across four terminals, allow extra time if your connection requires moving between the International Terminal and the domestic terminals.

Where to Eat

SFO has a strong selection of Bay Area cuisine and well-known local chains alongside standard airport dining, spread across its terminals.

Lounges

• The United Club is available across multiple terminals for eligible business/premium passengers, elite status holders, or paid access.
• Several Priority Pass-affiliated lounges are also available.

Duty-Free Shopping

SFO’s duty-free area includes Napa Valley wine and local chocolate alongside the usual international fashion, cosmetics, and electronics brands.

Layover Tips

• With 4 hours or more and a visa situation that allows entry, downtown San Francisco is reachable via BART in about 30 minutes.
• If staying airside, take the time to actually walk through the SFO Museum exhibits scattered across the terminals — it’s a genuinely accredited museum, not just airport decoration, and easy to miss on a rushed connection.
• Given the distance between the International Terminal and the domestic terminals, budget real time for connections that cross between them.
