I'm just starting to think about a RTW trip, but I'd be looking at it as a long vacation. this nested RTW is the most intriguing, but I have some questions. What I'm thinking is actually 2 x (A or D) OWE3(4)'s consisting of different continents. For example, have one NA/Europe/Asia (ex-US), and one Africa/SA/Australia ex-CAI. this way, I can take advantange of the CAI pricing for part of it, still get 6 continents, and (more importantly) get 40 segments. my thinking is that I can cheaply get from somewhere in europe to CAI while in europe, then do the inner one from there. Has anyone done a similar trip, or have ideas about it?
