The airport's "fact sheet" talks about 2 Delta SCs:
In the terminal: "
Delta Sky Club - 27,000 sq. ft. plus a 2,000 sq.ft deck"
In the North Concourse: "Delta Sky Club - 6,000 sq. ft."
However it doesn't specify a timeline. I think it's fairly safe to say the main club (at least parts of it) will open on day 1. But it doesn't say whether the North club is scheduled for Phase 1 (this year) or Phase 2 (2024).
