SFO Airport Guide

San Francisco International Airport (SFO) stands as a major gateway to the Bay Area, handling millions of passengers annually with modern facilities across its terminals. This guide equips you with everything needed for smooth navigation, from arrival procedures to departure strategies.

Understanding SFO’s Layout and Terminals

SFO features four main terminals: three for domestic operations (1, 2, and 3) and one expansive International Terminal divided into boarding areas A through G. All terminals connect seamlessly via the free AirTrain system, operating 24/7, and elevated walkways both before and after security checkpoints. This interconnected design allows flexibility; passengers can clear security at any terminal if holding a valid same-day boarding pass.

• Terminal 1: Primarily serves Delta, Frontier, and Southwest Airlines for domestic routes.
• Terminal 2: Home to Alaska and American Airlines, plus select others.
• Terminal 3: Dominated by United Airlines’ domestic services.
• International Terminal: Handles global carriers like Air France, KLM, Lufthansa, and United’s international flights, with dedicated gates for long-haul journeys.

The International Terminal’s G gates process arrivals, including immigration for international passengers, often featuring efficient lines though upgrades to automated systems are anticipated.

Finding Your Way: Maps and Navigation Tools

SFO provides interactive digital maps accessible via the official website or airport app, highlighting gates, services, and real-time updates. Static maps detail parking, baggage claim, and AirTrain routes. For visual learners, video walkthroughs illustrate processes like international arrivals at Terminal G.

Airlines and Flight Operations

Over 50 airlines operate from SFO, connecting to 128 destinations worldwide. Domestic giants like United, Delta, American, Southwest, Alaska, and Frontier dominate, while international options include Air France, KLM, Lufthansa, and more via alliances like SkyTeam and oneworld.

Check your airline’s terminal in advance to minimize walking. United splits domestic (Terminal 3) and international (Terminal G) operations, a common point of confusion for connecting passengers.

Plan to arrive 2 hours early for domestic flights and 3 hours for international to account for security, check-in, and potential queues. International arrivals involve U.S. Customs and Border Protection at Terminal G, with baggage claim following immigration.
