What Terminal Is United at SFO?

United Airlines, one of the major carriers at San Francisco International Airport (SFO), operates from several terminals to accommodate its diverse domestic and international flight offerings. As of my last knowledge update in September 2021, United Airlines primarily uses Terminal 3 (T3) and the International Terminal (Terminal G) for its flights at SFO. However, keep in mind that terminal assignments can change due to airport developments and operational considerations, so it's crucial to double-check the terminal information for your specific flight closer to your travel date.


Here's a detailed breakdown of United Airlines SFO Terminal:


Terminal 3 (T3):

- Domestic Flights: Terminal 3, also known as T3, is United Airlines' main hub for domestic flights at SFO. It houses ticketing counters, check-in facilities, security checkpoints, baggage claim areas, and departure gates primarily for domestic flights.


- Concourse F: Within Terminal 3, Concourse F is one of the main areas used for domestic departures and arrivals. It features various dining options, shops, and amenities for travelers.


- Concourse E: Concourse E is another part of Terminal 3 used for domestic operations, providing additional gate space for United's domestic flights.


International Terminal (Terminal G):

- International Flights: United Airlines operates international flights from the International Terminal, officially known as Terminal G. Passengers traveling on international routes will usually check in at Terminal 3 and then proceed to Terminal G for customs and immigration clearance.


- Concourse G: Concourse G within Terminal G is where you'll find United Airlines' international gates. It offers immigration facilities, customs clearance, international departure gates, and lounges.


Terminal 1 (Boarding Area C):

- Regional Flights: Some United Express regional flights, which serve destinations within California and nearby regions, depart from Terminal 1, specifically from Boarding Area C. Travelers taking these regional flights will typically check in at Terminal 3 and then proceed to Terminal 1 for their departure.


It's vital to verify your specific flight's terminal assignment closer to your travel date, as terminal assignments can occasionally change due to airport operations or renovations. You can check your terminal information through various methods:


1. Boarding Pass: After checking in for your flight, your boarding pass will display the terminal and gate information for your specific flight. United Airlines typically provides this information on the boarding pass issued to you.


2. Airport Website: San Francisco International Airport's official website offers information on terminal assignments for various airlines. You can visit the airport's website or use its mobile app to confirm terminal details.


3. United Airlines Website/App: The United Airlines website and mobile app provide access to flight-specific information, including terminal and gate details. You can enter your flight information or use the "Airport Information" section to find terminal and gate information.


4. Customer Service: If you're unsure about your terminal assignment, don't hesitate to contact United Airlines' customer service or reservation helpline for the most up-to-date information regarding your specific flight.


By following these steps and staying informed, you can ensure a seamless travel experience when flying with United Airlines from San Francisco International Airport.
