i'm on the tail end of a DONE4 with only a month left to travel. so far the ticket has been:

IST-LHR-DXB-LHR-LAX-SJU-DFW-ANC-DFW-JFK-EZE

i had grand plans to do the SCL-IPC run but have just run out of time.

for the next part of the itinerary i need to go to DEL. I am based in NY so i have to go to SA to pick up the ticket in EZE again. I'm trying to figure out the best way to get to DEL by maximizing miles and comfort. Ideally, i'm thinking about taking the ORD-DEL flight (so I can upgrade using EVIP) but don't know if it is possible given the fact that I can only transit in the US and don't have any segments left. So here are the two questions...

Is there a way that I can talk the ORD-DEL flight? (overland segments?)
If not, what is my best routing, EZE-JFK-HKG-DEL... on AA/CX or take an option through NRT so that I can upgrade the transpacific on AA?
