This summer, we're flying from LAX-MAD. Going on AA from LAX-SFO, then connection to BA for SFO-LHR-MAD. We decided to give ourselves a few hours in San Francisco to get some food.

Here's the rub: we will have two carryons, that I hope not to have to carry into the city. I know that we could store them at the Travel Agency in the International terminal, but that will cost us about $50 or so. We won't be able to store them in the Admiral's Club, because that's in Terminal 3, and once we leave security, our ongoing boarding passes are on BA, which (I think) leaves from the International Terminal.

Does the BA Club in the International Terminal have any secure luggage storage? If so, we could use our boarding passes to go in there and store our luggage before going into the city. Alternatively, does anyone have any other ideas where it won't cost us a small fortune to store luggage at SFO?
