nachosdelux, I haven't been through CDG recently, but I can definitively tell you that the CX lounge is better than BA's - not least because BA don't have one! However, having had the memsahib check them out last year, she tells me that CX is still better than the only other oneworld-operated alternative, which is the AA Admiral's Club - which is as woeful as Admiral's Clubs usually are.

You can read a review of the CX lounge here: http://www.ausbt.com.au/cathay-pacif...unge-paris-cdg.

Note there is no F/J distinction as it is a combined lounge.
