If you have a Delta Skymiles gold credit card it's $25 per guest. It's $50 per guest for a day normally.
This sky club was under construction when we were there. It was pretty busy too. Â The snack selection was ok. Â It was also a little warm in the club. Â If you leave, you have to take your bags with you.
Slight improvement with the addition of the SkyDeck.
The SkyDeck is cool, but the building blocks any good view of the runway...and it's hot as an oven out there.  Delta's done a good job with having an overhead shade, and  water out there, but even the ice melts too quick.
It's cool if you're an aviation buff, or just turned on by the smell of jet fuel burning.
