I'm flying YYZ-SFO on AC then SFO-SLC on UA next week. I understand that AC arrives at A gates, and domestic UA is at Terminal 3.
I read on another site that there is some kind of temporary walkway between the A and G gates in the international terminal, and then from the G gates I could walk to T3 while staying airside. Is this correct, or is there no way to get from A to domestic T3 gates without exiting and going through security again?
