Using AMEX membership miles for F/C travel; looking to go LAX to SYD (possibly on to MEL for a couple days to see friends). On the return flight I want to stopover in HNL for a couple days to recover from jet lag.

I know I can dump the miles into CO OnePass and redeem on Qantas (no HNL stopover permitted). Thought about terminating the trip in HNL and buying a OW tkt home ($$$).

Can also deposit the miles in ANA and redeem on UA; no service from SYD to HNL.

Can anyone think of other options for me?

Planning to depart on 30JUL

Thanks from a former airline employee that doesn't understand how to use mileage (but does a really good job at earning it!)
