OK, Thanks for the 300-day info.

I'm new to this lark with RTW so I take it it is fixed price? Per how many continents your going to?

So I book my first flight in D class, and if I want to add a sector, I can add one as long as its D class? Does it cost if I do this or is it as I say, a fixed price?

Maybe i'm being stupid on my part.. Not for the first time ^
