That entrance is already sort of open- from the D1 check in area elevator, it’s the door you exit from on the concourse level if you want to go straight to the gates. It’s across from the 30s gates.
Oh I def havent seen it then. I didnt even realize you can exit the D1 elevator anywhere else but at the Sky Club/D1 lounge level..
This is so exciting, cant wait til it opens. Just booked a Oct 11 ticket to JFK, no clue what I will do that weekend in NY but I want to experience both lounges on each end.
