I think it's worth noting that some people looking here should also be looking at a RTW from KL. This is not the ST, but one they put together with thier own (odd) alliance. There are several threads in the KL forum about this, and Cris L here can probably shed some light on its current status and prices ex-CAI. A couple months ago a 25K in J was coming in at around 1900€ and this includes travel on KL, MH, KQ, and EK as well as pretty much all of the usual KL suspects. It's USD$1000/segment to upgrade to F. I'm thinking F on EK and MH are pretty nice, and the truth is that KL, NW, and CO J are not exactly torture for that kind of money. Of course, you only earn KL miles on their partners - not EK, for example.

It has been a nightmare for me to try to book this and so far I no success, though I haven't been pushing too hard.
