Looks like the Flagship Lounge is official, TPG was told it is opening in 2025 along with a new Admirals Club. Based on that rendering, it looks like the A West space will be a Flagship Lounge on one side, Admirals Club on the other.
I'm hopeful that opening an A-West AC means they can make a meaningful refresh (even if not a full renovation) to the B/C club. A lot of those chairs are in dire condition.
