According to minutes taken during the bidding process, MAG proposed splitting the area into two lounges. One would be the American Express Centurion lounge. Only holders of American Express' Centurion (an elite by-invitation-only card) or Platinum cards can use this lounge.
The placement of Cent Lounges in ex-US Airways hubs continues. I can only hope that DCA is next.
