The Delta SkyClub opens on concourse A today.
According to news reports, it is 14000 SF and seats about 250, with expected traffic of 400-450 guests per day. Looks really nice from the pictures.
by contrast, Admirals Club at C/D is 23000 SF. Not sure what the capacity is. And it can hardly be described as “nice”
pretty embarrassing for AA that Delta has will have a much nicer lounge for their 7 gates than AA has at a major hub….but it’s consistent with how AA treats CLT.
