I have a question regarding the number of exit doors there are for those who arrive at SFO.

I've never had a domestic connection after arriving on an international flight.
i have a friend who will be having a domestic connection probalby on UA, i would like to see her before she connects.

does everyone exit through the same big white doors or is there another exit for connection flight passengers?

from the look of it, it has a second door designated for transfering flights correct "connecting flights exit"? If so, where can i find that exit?
