It does indeed. If that is the case, I'm stunned that the AA lounges at LHR have any customers other than economy class AC members given the BA lounges in the area.

Probably because the AC lounge is in Terminal 3 (where the AA flights arrive/depart), and the best of the BA lounges are in T1 and T4. Or more to the point, as we have seen from the "experts" here, not many people are aware of this reciprocal access availability.
