Went to the Club yesterday on arrival. Got some additional info.
The Club is smaller than the old Club but seats more people. Looks really nice and as BamaGirl pointed out, nice furnishings. DL wanted more space but the City wouldn't agree to it. (IMO - DL wouldn't make pay-offs).
The food area is larger but since the Club is narrower there will be traffic congestion. Real dishes and silverware! Crawfish Pasta is new.
There'll be 2 elevators in about a month. Not DL's issue, but Airport Authority screw up. If you can't do the 31 steps and can wait a couple of minutes DL will get you up or down on the freight elevator.
The entire airport facility isn't really ready but the delays were costing airlines and vendors so much, they opened anyway.
Non Club related. There appeared to be 7 TSA lanes but only 1 Pre lane. The Pre lane (also Clear) is at the far right as you enter the terminal. The C Gates, DL and the Club are at the other end of the TSA area.
