I've got 25,000 miles in Asia Miles.
I've only got 600 miles on American this year.

I'm about to book a round trip from ORD to Perth.

I'm confused with AAdvantage vs Asia Miles, so should I book this new trip using my Asia Miles number, or my AAdvantage number, and start building some One World status?

I am Gold Premier on Star Aliance, but the One World carriers are so much cheaper on this route.

I'll be making this same trip a couple more times, this year.

This board is so full of knowledgeable travelers, so please give me some advice....
