What web site or agent
 

Hi guys. I am looking for a multi-destination rt. ORD-DEL-DXB-ORD. Any recommendations? Also need hotels as well. Thank you. Larry :-)

Try using itasoftware.com - you can't book from there, but they direct you to the site they find the routings at. sidestep.com is also useful.

Dates? Class of service (economy, business etc?)

www.kayak.com will do that.

Thank you. I have tried kayak. I'll try the other one mentioned too.

For RTW trips, I like this site:
http://www.roundtheworldticket.com/tripplanner.shtml

it uses consolidator tickets so that can save you decent $.

Thank you. I'll check it out.
