American Airlines Philadelphia Flagship Lounge Expected To Double In Size, Taking Over The Admirals Club Next Door

American Airlines’ gorgeous Philadelphia Flagship Lounge may finally get the space it should have had from the start. Lounge staff are reportedly telling passengers it’ll take over the Admirals Club next door around March 2027, essentially doubling the size of the business class lounge before next summer’s transatlantic seasonal peak. That’s the change I called for when the lounge opened. But there’s a potential problem for Admirals Club members since there’s no announced replacement for the club they’d lose. A passenger reports being told by the employee managing Flagship lounge entry that it would expand into the adjoining A West Admirals Club “sometime around next March.” Another commenter says an agent separately told them about expanding to the whole floor (which is the same thing), after they gave up on finding a seat in Flagship and went next door. Officially, an American Airlines spokesperson tells me: Nothing set in stone right now, but we are always evaluating how we can best serve our customers during the summer peak next year. In my original review, I showed the connector behind the check-in desk. There’s already ‘swing space’ that can be opened to either lounge. During my visit it was part of Flagship. These are adjoining spaces with the same beautiful design, and they’re already connected. The dimensions of the spaces are: Flagship: 12,500 square feet, with 200 seats. Admirals Club: 11,000 square feet, with 181 seats. Additional flex space: 1,364 square feet. That’s nearly 25,000 square feet across the complex. Moving the Admirals Club space into Flagship would roughly double its footprint. I quite like this lounge. In the morning and early afternoon, it’s a lovely place to spend time. The trouble comes before the bank of transatlantic departures, when the passengers it’s supposed to serve all arrive at once. A business class lounge needs enough seats for people flying business class. And in the summer from Philadelphia that total grows quite a lot with American’s seasonal services. Things are even worse now that the A West terminal has lost the American Express Centurion Lounge for expansion into the British Airways lounge space, expecting to reopen by the end of 2027. I’ve covered the project taking over the British Airways lounge space below. The British Airways lounge is closed, too. I actually think Flagship was already better than both lounges. It’s just crowded (but not as cramped as Centurion was!). American has been investing more in lounge food. At Dallas recently, I found a better buffet, staffed charcuterie and food ordered by QR code that arrived at my table in four minutes. Philadelphia helped introduce that ordering system, coming after the Soho lounge at JFK which is shared with BA. Philadelphia wasn’t built with a separate Flagship Dining room. Those are operating in Dallas and Miami, and I broke the news that Los Angeles reopens this week. Chief Customer Officer Heather Garboden has talked about rethinking Flagship. Delta was the last of the big three to introduce a separate business class lounge, and I think Delta One lounges now offer the strongest overall product. American’s access rules are much more generous, including eligible elites flying coach on qualifying international trips and oneworld Sapphire and Emerald members from programs other than American and Alaska even on domestic itineraries. That makes having enough space especially important. American had an Admirals Club in A East. They closed it when these lounges opened in May 2025. I argued then that they should keep A East for Admirals Club members and dedicate A West entirely to Flagship. Under the reported plan, the nearest Admirals Club would instead be B/C. Someone paying for a membership, or carrying the Citi Executive card, would lose access to the beautiful A West club without gaining access to the larger Flagship Lounge. American should take back the A East space as well. Topics on this page
