ANA still requires awards to be booked as RT, correct? I'm not sure what my return plans are as I may be flying back with my wife and she is restricted to certain carriers through her employer. However, if it is a better deal for me to book the RT, we may just take our own respective flights back to the states.

I also did find availability on Asiana, but the ICN to SYD leg is economy. While not preferable, it is another option that could be tolerable.

EDI: I found the ANA flights to NRT on UA.com for 75k...does that mean I can book it as a one-way with no return leg needed?
