How do I get from domestic to international terminal in San Francisco?

Seamless Travel at SFO: Mastering the Domestic to International Terminal Transfer

San Francisco International Airport (SFO) is a bustling hub, but transitioning between its domestic and international terminals is surprisingly straightforward. Forget stressful taxi rides or confusing shuttle schedules – the key is the AirTrain Red Line.

This free, automated train system provides a smooth and efficient connection between all terminals, including the international terminal. It operates on a continuous loop, moving clockwise and providing convenient access to every terminal, as well as the BART station (for those connecting to public transport), the airport’s numerous parking garages, and even the Grand Hyatt hotel.

Here’s how to use the AirTrain Red Line for a seamless transfer:

1. Locate the AirTrain Station: Your journey begins at the AirTrain station nearest your arrival gate. Each terminal has clearly marked signs directing you to the station. These stations are generally located close to baggage claim in domestic terminals.

2. Board the Red Line: Simply board the AirTrain and find a seat. The trains are clean, comfortable, and run frequently, ensuring minimal wait times. No tickets or payment is required.

3. Identify Your Destination: While the train runs continuously, pay attention to the digital announcements and terminal signage within the train cars. This will help you know when to disembark. The announcements clearly state which terminals are upcoming.

4. Disembark at the International Terminal (Terminal G): The International Terminal is clearly marked. Once you disembark, follow the signs for your specific airline and gate.

5. Allow Ample Time: Although the complete AirTrain loop takes under ten minutes, always factor in extra time for walking to the AirTrain station, potential waits, and navigating the international terminal once you arrive. Aim for at least 30 minutes, especially during peak hours.

Beyond the AirTrain:

While the AirTrain Red Line is the most efficient method, remember to check your airline’s specific instructions for connecting flights, especially regarding baggage transfer and security checkpoints. International flights often require more time for security and customs processing.

In conclusion, navigating between domestic and international terminals at SFO is incredibly convenient thanks to the readily available and efficient AirTrain Red Line. With a little planning and awareness, you can ensure a smooth and stress-free transfer between flights.
