Which international club do you think is an exception?
BAA in LHR requires passengers accessing a lounge to be departing on an airline that operates from that terminal. So if one was departing on IB from T2 @ LHR the AC member could not access the AC in T3. But if the AC member was flying UA then they could since UA and AA both depart from T3.
