I'm really happy for the AA J flier as they've had to put up with an inferior product for many a year.....and of course a lot of their J fliers will still have to put up with old product for a while yet.
It's not only the new AA J that "wipes the floor" with CW there are several airlines J seats out there that are better....even the new IB one. You have to remember the current BA CW seat has been around for yeeeeeeears and the new one will be coming soon.
