Good to hear you got around the stopover rules, even if you're nuts! That's a whole slug of miles in a short period of time, but I'm glad you'll give yourself time at the airports and hopefully you'll be dead to the world in CX rather than dead.

Depending on how much you spend getting/staying there, ex-CAI can not necessarily save you all that much. That said, an award ticket there is probably the worst use of miles. Generally a lot cheaper to fly over on AA metal with a VIP upgrade and use an award ticket on BA for half the miles (or even purchase a ticket depending on what they're running.) Long flight to sit in coach for, but BA often upgrades elite to Club World.

But to each their own, and it sounds like you have this pretty well planned out.
