The good news is that Airspace Lounge is on Concourse D and we look forward to seeing Delta flyers in December.
American Express Platinum and Centurion members (cards that have the lounge access program as a benefit) get complimentary entry for themselves and two guests or immediate family. If not, it's $17.50 and every entrant, including guests, receive a complimentary choice from our extensive lounge food menu or a free alcoholic drink, coffee from Peet's and of course free wi-fi (it's $8+ on the concourse) and soft drinks. We know in some respects this isnt as good as having a Skyclub for those of you that are Skyclub members, but we like to think that we offer a very solid customer value proposition versus the other options on the concourse.
Airspace was reviewed today by the Washington Times. See the review here that has a great picture of our "D.C. Roast Beef Sandwich" that is among the items included with entry and also
see our full menu here. Note that even though there are prices, the first food item or house/dom/rail alcoholic drink is included with entry.
