Dino,
Did you say slots ?
"Slots" on my blog
Here's the place to start.
The U.S. Code (i.e THE LAW)
It is, of course, legal mumbo jumo but it is the law.
The "High Density Rule" (cited above) is the only slot program I am aware of. After that, it's the FAA Command Center working in "collaboration" with the airlines to cut flights when things get backed up enough to where it's too late.
I've been studying this issue since I retired. If I can help, just holler.

Once you get to my blog do a "search" (on the top left) for -- slots I think it took the link to the U.S. Code. The link is a mile long so if it didn't, email me and I'll get it to you.
