I'd like to travel to Australia around Thanksgiving this year and booked JFK-HKG-SYD outbound, CNS-HKG-JFK return with CX 100K award. I plan to purchase one way QF ticket from SYD-CNS.

However, a friend of mine mentioned that there's an "OneWorld Gateway" award that would enable me to do JFK-HKG-SYD on CX and SYD-CNS-LAX-JFK on QF, for about the same mileage. I tried to find it on the AA site but the only thing I could find is the Multi-carrier award. Calculating total trip miles it would be around 20000 so at least 130K in business class.

Is there a OneWorld award that would be better than the CX one? Also, if I buy the one-way SYD-CNS from QF, am I qualify for the Australia pass?

Thanks much,
