Is 2 hours transit time in SFO enough for a NZ-citizen flying Kelowna,BC - SFO - Auckland? and How long does it take to transfer from Terminal 3 to Terminal 1 at SFO? are not duplicates because my situation is different — no customs to worry about. However, if I fly into SFO on a domestic flight, get off at an ‘F’ gate, and have to check in for an international flight, can that be done without going through TSA again? If both are on time I'd have three hours, seven minutes. The flight to SFO is a hundred dollars cheaper than anything else I've found so far.
From the far end of 'F' to the far end of 'A' is more than a kilometer, but I don't know where check-in is for China Eastern, or whether I can check in/print tickets in advance online.
