My family and i fly from Missouri to Sydney yearly to visit her family. We try to bank as many miles on AA as well as QF.

Last year I had enough for an award ticket on AA. Total cost was approx $125.

This year my wife and son had a enough for an award ticket on Qantas. Cost was approx $850 each! (Yes that is less than a ticket) But when I questioned the Qantas rep she said it was due to fuel surcharges. I speculate the carbon tax imposed in Australia. Not looking for a political debate.

My question is this. Is there a way to make sure the miles we fly can all be earned on AA rather than them being split between AA and QF. Our US legs on American credit to AA. Our Qantas leg gets credit towards QF. I would like to keep them all with AA to earn quicker and pay less when using.

I posted here rather than in American thread and Qantas thread since it is kinda both

Thanks
