Understanding Your Connection: Terminal 3 to International Terminal at SFO

Follow the signs directing you toward the International Terminal G area. This walkway exits conveniently near Gate G92. The walk typically takes about 5 to 10 minutes.^[1] It is a quick transition.

Taking the AirTrain (Best for A Gates)

If your international departure is from the A Gates, the taking AirTrain SFO terminal 3 option is your best friend. First, exit the secure area in Terminal 3 and head to the Departures Level. Follow the clearly posted signs to the AirTrain station, which is located in the main parking garage.

Once at the station, board the Red Line or Blue Line. You will want to exit at either the International Terminal A or International Terminal G station, depending on your gate. Always double-check your gate letter on the airport flight screens before boarding the train.

Minh's Experience with the SFO Connection

Minh, a frequent traveler flying from Ho Chi Minh City through SFO, once struggled during a tight 90-minute layover. He was arriving at Terminal 3 and needed to reach the A Gates for a connecting flight.

He initially tried to find a walking path through the secure zone, but soon realized that the A Gates are completely separated from Terminal 3 by the international complex. He was stuck.

After a moment of panic at the gate screen, he rushed to the AirTrain station. The train ride was smooth, but re-clearing TSA took much longer than he expected due to the mid-day crowd.

He made his flight with only minutes to spare. His lesson? If you see an 'A' on your boarding pass, don't waste time looking for a walk-through; head straight for the AirTrain immediately.
