Saw the new T4 space (still under construction) ... it is going to be very nice when finished, with similar branding/look/feel to the new JFK lounge. The Flagship Dining/bar area sounded really nice, too. And once both lounges reopen later this year, the T5 lounge will have plenty of room - it will have fewer seats than Delta packed into the space, but still a lot considering AA will still be operating just four gates in T5 for now.
