Thanks for the suggestions. The only reason I do this is availability of award flights. I called Aadvantage international travel and I was told there is no award flights available for the whole month of February.
How do I check availability of OnePass flights? With StarAlliance I can use the ANA tool. Is there something similar for OnePass? I am trying to get from DFW to either KUL or SIN.

Worse case scenerio is to book the award travel with overnight stay in NRT.
Any other ideas?
