As posted in the trip report section, my wife and I finished our first RTW our oneworld. If was a great experience, and we will do it again for sure. The one thing I wished I had figured out before hand is this.

Since we have a segment limit on a RTW ticket, and transfers count as segments, the normal transfer rules really don't apply to RTW tickets in a meaningful way. What I mean by that is that you can schedule your ticket to get you to your transfer airport as a separate leg, and avoid all the normal transfer rules.

For example, one of the sections of our trip was SIN-xHKG-CDG. The original booking was actually SIN-CDG with a transfer at HKG that had to obey the airline transfer rules, specifically time in HKG. Our connection at HKG was less than two hours and I was a bit worried about it the whole time (it turned out not to be an issue).

But I realized after the fact, that I could have booked it as SIN-HKG, and HKG-CDG as having nothing to do with each other (except being on the same RTW). Then I could have made the transfer time anything I liked, say 8 hours, and all RTW rules would still be satisfied. The reason I would have liked a much longer time is that the frequency of planes from HKG-CDG is low enough, I really didn't want to miss it.
