How to go from domestic to international terminal SFO?

Navigating San Francisco International Airport: From Domestic to International Departures

San Francisco International Airport (SFO) can feel like a sprawling city unto itself, especially when you’re navigating connections. If you’re arriving at a domestic terminal (Terminal 2 or 3) and need to connect to an international flight departing from the International Terminal, fear not! The process is generally straightforward and designed for smooth transitions. Here’s a simple guide to get you where you need to go:

Two Main Options: AirTrain or Foot

SFO offers two primary methods for transferring from a domestic terminal to the International Terminal: the AirTrain and walking. The best option for you will depend on your gate locations, the amount of luggage you have, and your personal preference.

• The AirTrain: Your Speedy Connector

  The AirTrain is a free, automated people mover that circulates throughout the airport. It’s a convenient and efficient option, especially if you have a considerable amount of luggage or simply prefer not to walk. There are two lines: the Red Line and the Blue Line. Both lines will take you to the International Terminal.

  To use the AirTrain:

  1. Find the AirTrain Station: Look for signs directing you to the AirTrain. These are typically well-marked throughout Terminals 2 and 3. Follow the signs, which will often lead you to elevators or escalators taking you to the AirTrain platform.
  2. Board the AirTrain: Both the Red Line and the Blue Line stop at the International Terminal (A Station). Double check the signage on the train before boarding to ensure you’re heading in the right direction.
  3. Disembark at the International Terminal (A Station): The AirTrain makes frequent stops, so the ride should be relatively short.

• Walking: A Direct, Exercise-Friendly Choice

  For those who prefer a bit of exercise or are traveling light, walking to the International Terminal is also a viable option. Clear signage guides pedestrians between the terminals. The route is generally well-lit and flat.

  To walk:

  1. Follow the Pedestrian Walkways: Look for signs specifically indicating the walking route to the International Terminal.
  2. Proceed to the International Terminal A Station: The pedestrian walkway will lead you directly to the International Terminal A Station.

Once You Arrive at the International Terminal

After arriving at the International Terminal A Station (whether via AirTrain or walking), you’ll likely need to find your airline’s check-in counter.

• Check-in and Baggage Handling: If you need to check in or drop off checked baggage, proceed to the Main Hall of the International Terminal. Look for the signs directing you to your airline’s specific counter. Remember to have your passport and any necessary travel documents readily available.

Important Considerations:

• Time Management: While the transfer process is generally efficient, it’s always best to allow ample time for connections, especially at a large airport like SFO. Factor in potential delays, security lines, and walking distances.
• TSA Requirements: Remember that you may need to go through security again when entering the International Terminal, even if you already passed through security at your origin airport. Be prepared to follow all TSA regulations regarding liquids, gels, and prohibited items.
• Information Booths: If you’re feeling lost or confused, don’t hesitate to seek assistance from SFO’s information booths. Friendly staff are available to provide directions and answer any questions you may have.

By following these simple steps, you can confidently navigate from a domestic terminal to the International Terminal at SFO and ensure a smooth start to your international journey. Bon voyage!
