Thanks. I thought that my reading allowed IST, so now I'm not sure!

The changes for the transcon will need to be made though.

I would like to add another NA sector, but can't think of one that I can add on this routing- any ideas? Perhaps BOS between MIA and DFW or between DFW and ORD? This would give about 46000miles 105000 AAmiles.

I did mean YVR! Sorry about that.

Would adding ORD here fix the transcon problem? Removing MIA would then give me 20 sectors. This should get me about 55000miles- or 120000 odd AAmiles.
I think I have almost maxed out my mileage?! Any tips to add some extra miles without extra sectors would be gret. Also can I use CX888 from YVR to JFK?

I'm just waiting for some pricing from CMB, and some of the general things (not including taxes or routes)
