1. Yes, but...
2. No, the airside connection is between T2 and T1C. There is no airside connection between T1B and T1C.
3. Sorry, no; A and G are on opposite sides of the International Terminal. A has no airside connections. G has an airside bridge to T3F. T3E and F are connected. Put T3E, T3F and International-G together and that's about 40% of the gates at SFO all connected airside.
