I am confused about how I can use my Qantas miles to book American Airlines flights. I am currently earning miles on Qantas, because AA requires 2500 miles before I can earn AA miles on Qantas equipment.

When I return to the US, I want to use my Qantas miles to book an AA flight. From my (limited) understanding, I think I need to book through Qantas and will be subjected to their 2500 "assistance" penalty, correct?

The major issue is that I won't be flying qantas in the near future and want to use up my miles. Thanks!
