Anyway, as jamienbaker pointed out, the SFO-LAX-LIM may very well be "phantom" inventory. There's likely really no more than 1 seat currently released for the LAX-LIM leg, no matter what the BA site claims.
FYI, if AA tickets, they'll protect. They're unique in this regard. Policy on website, though I'm too lazy to find. I do unprotected bookings on AA often, but would never risk it if ticketed by other airlines (I.e. BA).
