So or those who haven't actually been IN the airport recently...
B Concourse Admirals club completely remodeled - it is done...not much ( if any) larger but a better layout - restrooms didn't get any larger - so any talk of Admirals Club rennovations in the future must be talking about the C Club
The old US Air club in D has long ago been over run with shoppes - right across from the new 'plaza' - that space is utilized
A Delta Club is in the artist rendering of the next phase of 'new A' development
AMEX Centurion lounge may take some of the pressure off the Admirals Club (I prefer AMEX) and the Admirals Club now requires same day ticket on American - that certainly reduces the appeal of 'membership' for those who fly airlines other than AA - that may also reduce the over-crowding in the AA club
