I've been doing my homework for a while now and soon ready to book my first rtw that'll take place in july. But yet I'd like to hear some experts thoughts if I have any logic here what I'm thinking

So routing is supposed to be like this:

hel-lhr-syd-hkg-nrt-hkg-jfk-bgi-jfk-sfo-ord-anc-ord,
lax-scl-ipc-scl-lax-lhr,
lhr-dxb-lhr-hel

From ORD to LAX I was thinking to buy a separate ticket ord-sfo and then surface to LAX.

Important destinations are IPC, NRT and SYD (actually nz with separate ticket) and the rest are more or less MR. DXB will be a separate holiday later.

This routing shows me 71663 miles and since I'm crediting this to AY points, It'll be about 115253 km. And when I'm flying in first, I'll have triple points. If I got this right, all of these routes have A inventory? So I'll have about 345000 pts and since I'm AY silver, I'll be Gold (ow sapphire) in july and ensure my gold benefits until 7/2010 (unless I hit the plat limit).

I guess there's no way to get significantly more miles (or points) in NA or elsewhere?

Cheers
