A very quick confirmation please.
I have managed to bag a 2 x RTW F redemption using AA miles. Starting in LHR on CX to HKG. I have no status any more

but would like to visit the new GF in T3. I think I am permitted under the oneworld lounge alliance but not sure as CX have a lounge (a new one I think) in T3. Can I get confirmation that I am permitted to use the GF lounge on CX F ticket?
I have searched and found threads that say this is OK but I dont want to make a fool of myself
Many thanks
