Normally I book my star rtw tickets with a travel agent, but as I have a couple of UA issued star vouchers, United have told me they will have to issue my ticket.
I would like to book my itinerary online to see if at least I could get the extra 1000 miles being offered in Australia.
As a former travel aget I could just book each segment in the correct class of service required, ie B or M...is there a way to do that on UA online?
I can only see to put all the segments in requesting economy and hope it converts it...if not will UA reservations change it to the correct class?
Or should I just let UA book it all direct?

I'm asking this just before I go to bed, hoping that in my morning I will have an answer from various experts. Even those Flyertalkers on the Oz east coast get up 3 hours or more before me
