Have been in both the AA and CX lounges at CDG in recent weeks, so happy to share my experiences.

The AA lounge/Admirals Club is actually very nice - hardly the BA F lounges at LHR or the CX lounges at HKG or the QF ones in SYD - but a very comfortable and welcoming facility, with most things you would want/expect in it.

Lots of comfy seating (though without easy places to put your drinks down, bit of a design flaw), a computer room like the ones they have in their bigger lounges in the US, long bar type thing with lots of drinks and nibble options etc. (Not sure there are showers though... but I could be wrong).

My big issue always with AA lounges is the lack of real food, and this is the case here too... however, and it is a big however, the one thing that was available were without a doubt the nicest tuna sandwiches (seed covered baguette sections with the filling) I have had in years! Gorgeous. Had four of em!

The CX lounge is meanwhile very small, but quite cute and comfy. Some one-seat sofa and mini-table seating, some reading stuff, some refreshments etc, in open style one level up looking over some of the gates. (Reminds me in size and style of the F section of the QF/BA lounge at HKG, if you know it).

Big advantage of this lounge is its right above the gates... BIG disadvantage is that they ONLY call the CX flights !!!! (A clever way of keeping us OW Em. and Sapps. out unless we are flying Cathay!).

Hope this helps!
