$39 per person, and it's single club access not a days pass to multiple sky clubs.
I have never paid. But I think it is $35 to $50 per visit. But it is included with the Platinum American Express. For the Delta card to cover it you need the top card, Executive.
It has to be a platinum card.. about 500 a year
Like $600 a year. Well worth it for frequent travelers.
