I'm going to be working in Tokyo later this year & would like to start a RTW (including London, some of Europe, NYC, San Fran, New Zealand & Australia) in Business or First from there or somewhere nearby.

I'm actually based in Sydney, AU but from what I've read it's going to be cheaper buying and commencing this fare from Asia.

Do any of you smart FT-ers have any suggestions on how I should tackle this?
