After reading it through it, it's unclear as to what will happen with NRT slots. It could be some landing rights, it could be slots (good for one PHX-NRT r/t starting in 2012).

For Brazil, it ends up looking like it's not slots at Sao Paolo, but a route-agreement trade. DL will trade one of their unrestricted USA-Brazil rights (one in question is used on ATL-GIG; DL has 14 more of these, used for ATL-GRU and JFK-GRU); in return, US gives DL their Brazil allocation, which must be used to GIG.

In the end, DL loses nothing (but a little bit of flexibility in the unlikely event ATL-GIG ever goes away), US gains the ability to do CLT-GRU (a route that's more sustainable than CLT-GIG, due to the business nature of GRU). US will still have to get the actual landing slots in GRU somehow, but this gives them the rights to fly to GRU.
