I would love some help from the experts with a routing we are looking into for departure July next year, in coach. One of us will go by CIRPAC and the other on a OneWorld award flight:

BNA-DFW-OGG on AA
OGG-HNL-KIX on AA codeshare
KIX-HKG-CNS-DRW on CX/QF, not stopping in HKG or CNS
DRW-ASP on QF
ASP-MEL on QF
MEL-LAX-BNA on QF/AA

There are better connections from Osaka to Darwin on QF/codeshare, but we need to fly CX because the oneworld award requires 2 carriers other than AA if you are using AA miles (which we are). As far as I can tell, I am OK on stopovers for the CIRPAC (five) but I need to purchase two more rather than one (you get 4 for free on CIRPAC) as you are only allowed one in Australia.

My questions are whether that routing fits the CIRPAC fare rules, and what seasonality would apply. Thanks to you all for your help.
