Thanks. I know this is quite a controversial point so I have decided to travel JFK-SFO instead as my A Class upgrade on the 763 aircraft came through!
Although a Skybed is better for a 5 hours flight, the though of having a big stuff up like this at the airport is just not worth the hassle and also given it will be BA/QF that will be issuign the BP @ JFK, I don't think you can play dumb. Also carrying 2 cases @ 32kgs each to go from T7 to T9 is not something I want to do!
