ozstamps - ANY ticket purchased in India for travel originating in India will be cheaper than other countries. Specifically, RTW fares are significantly cheaper (a min of 25% in C and F). I would expect UA to price their "new" UA 1/2 service accordingly. In addition most travel agents in india will rebate their commission upto 8%.
As the date nears I am sure you will find special deals from UA and from local agents. If you are seriously interested in the first flight (eastbound or westbound??) I could ask my agent to update me on fares and convey the same to you.
