On a recent RTW award trip, I was able to take our entire family party (NM, Mrs NM, inlaws and 3 mini-NM's) into AC's in LAX and DFW. No questions asked. Just showed my QF Platinum card (OneWorld Emerald) and Mrs NM's Bronze Qantas Club card.

I questioned a AC agent at DFW on a previous trip and she said I could take my entire family if they are travelling with me. I said that will be seven people and she said that was fine - so long as they are my family. Obviously the in-laws have a different surname, but their relationship was never questions.

We were always offered one drink voucher per adult (4 in our case).

Also were granded access for the family at BA lounges at YYZ and LHR, and QF liunges at BNE, AKL, HGK and SYD Domestic. Only at HKG did they request Qantas Club guest passes, of which I was carrying over 50!

I have never had any problems with AC lounge access and never had to ask the agent to go look it up. Then agaon, most of my AC access has been at LAX and DFW where they get a lot of QC members due to lots of codeshare flights.
