CX has a quite small and intimate lounge at CDG. I am quite sure you can access it with Sapphire status. Was there some 4 weeks ago.
I was flying AA CDG-DFW, and were in the Admirals Club lounge "downstairs". Asked if they had any internet terminals, but no. Took a walk around and saw the CX lounge. I entered with my AA EP card, and they had 3 or 4 nice broadband internet terminals there. And some nice chilled Tsing Tao beers.......
I told the staff @ the AC about the internet terminals at the CX lounge, and they did not know about that! (at least they said so...)
