Welcome to OneWorld RTW mania! It's addictive. I'm already wondering where I'll buy my next one. How much did you pay for yours?

Keep in mind that you can only have two stopovers in country of origin (Asia).

154N . 3. MAXIMUM 2 STOPOVERS PERMITTED IN THE CONTINENT
155N . OF ORIGIN.

You haven't indicated which are stopovers and which are connections in your list above.

I agree with the recommendation of a LHR-DXB turn. It is a 3 class plane, so very comfortable travel and a lot of mileage. DXB is an interesting place for a couple days - or you can just mileage run it.
