Getting between terminals

Every terminal at SFO is joined by post-security connector bridges, so once through security you can reach any lounge without being screened again. The layout is a loop — Terminal 1 to 2 to 3 to International G to International A and back to Terminal 1 — which means the two International boarding areas are the awkward pair: getting from A to G airside involves walking the whole way round past every other terminal, and clearing security again at the other one is usually quicker.
