RTW Ticket from India
 

I want to start my posting by saying how much help and information I was able to get from this message board. Everyone seems to be very nice and helpful. I am wondering if I can build a RTW trip from Bombay. I want to go to New york first. I am staying for about two months. From New York, I have to go to Lusaka, Zambia and return to Bombay. I want to fly First Class. Can I return to New York from Zambia before returning to India? How can I work this out? Any ideas? I was on CX and AA first class last year. CX experience was great. Would love to try BA FC. Can I do BOM-HKG-NYC-LHR-LUS-LHR-NYC-BOM? Any help would be greatly appreciated. Does anyone know where I can buy this in Bombay? Thanks in advance.
