I'd like to start planning a trip around the world from Jan 2008 - Jun 2008. I've been in the process of signing up for credit cards and accumulating miles so I hope to do a lot of this trip using those. The trip will be something like this:
NYC - Beijing- Bangkok - Dhaka - Mumbai - Karachi - Istanbul - Warsaw - NYC

I'll be planning trains and other transportation to move around those areas. I may need to add one or two cities to the itinerary.

I'm trying to find the tools that will help me figure this trip out. I searched through the tools from the other forum. Is there tool/site that will let me know who flys in/out of every city? So once I have my locations setup I can see what airlines fly those trips?

I think star alliance has an "around the world" fare too, which I'm curious how many miles I'd need for that. If anyone's planned a similar trip let me know what resources you used.

I'm currently building miles with Delta, United, Hilton, Starwood, and Marriott.

Thanks.
