For clarity I did mean should the poster be travelling in F on UA out of FRA, he/she would not have access to the LH HON lounge so my statement still very much holds water. Remember in my post I was referring to partner lounge access.
FWIW, when BA and QF were both in T4 LHR and BA still had the CCR, QF F pax had access to the BA CCR.
