Just one thing you need to remember, whilst you will be travelling on an 'A' ticket, not all of your flights will offer 'A' and you will end up in 'D' on some of them - certainly the flights within Australia, and IIRC the USA-Canada flights.

The basics in terms of miles are that, as Plat (or indeed Exec Plat), if the flight is booked in 'A' you will get distance*2.5, if the flight is booked in 'D' you will get distance*2.25.

If you do all of your 2nd AONE* in 2006 you will have no problem getting Exec Plat - which gives Exec Plat untill Feb 2008, Plat until 2009...

On your routing front, have you sorted out Asia - last time I checked you had 5 segments I think? Post below if you wish.
