Am thinking of booking RTW flying BC. I have been looking at doing this booking on the Star Alliance web site I would appreciate comments as to whether this is the best place to do it. Thanks
Will be doing award travel, sorry I forgot to mention this in the OP
That makes a massive difference
What ffp's do you have ff miles with? What rules do they have for awards?
Many ffp's now do not allow stopovers on awards, so will be point to point
Consider these
Award booking services - a list and some reviews
Edit
OP changed post 3 from award to paid as I was replying
