I am flying in on American and meeting a friend that is flying in on Delta. We are suppose to meet our driver at the Delta Arrival area. How do I get there ?

You are supposed to park if you are ahead of time but you must pay the parking fee per hour , or you can go out there outside where you can see cars passing by, stand out there where your meeting place is.

You would need to take the airport train from your terminal to the Delta arrival terminal. The train has the terminal names by airline.

There should be directories that show what wing American airline flies into and the concourse for Delta. I do not know the lay out of San Francisco Airport other than where Delta is. We use Uber or hotel shuttle service to drop off or pick us up.

Awesome!
