The AA AC at SFO is OK, and I used it last month before my AS flight to SEA, but I had an onward JL flight to NRT, so OW rules applied. They did scan my AS BP, and I showed them my eTicket as I didn't have JL BP's as OLCI wasn't permitted for passport check. I'm wondering if AS would move to the South Terminal also, but for the upcoming AS lounge opening in "T2".
