We are almost exclusively AS fliers. We use BA and other partners airlines as well. Unfortunately we happen to have tickets on a medium haul flight on OS (Austrian Air). So where do we stash the miles to best serve us in the AS partner/market place. I know you guys are clever. I could not figure it out. It hurts to put it in mileage plus.... We don't use those airlines after all.

What is an AS loyalist to do?

P.S. We do also collect Amex MR points. I suppose we could open an ANA account?
