I asked the AA RTW desk this very question a few months ago, and had a long and complex discussion. Bottom line is that only one possible routing through Hawaii: SYD-HNL on QF and then you can use AA to go to the mainland (either eastbound or westbound). No open jaw or surface segment allowed. No creative alternatives -- they really don't want to include Hawaii on the NA segments. Absolutely not allowed to do DFW-HNL//LAX-HKG for example. When JL joins Oneworld this will get a lot better.
