Actually, RDU is not anyones hub anymore. We used to be an American hub but no more.
The problem I am finding with AA is that I have never been able to find reasonably priced domestic flights with them.
*****************
I was wondering if my basic reasoning is sound? Once I pound out the original miles/dollars to get a top tier status, will I be consistently upgraded buying bargain basement fares or should I save my money and just shell out for better travel when I really want it?
I still don't get the logic of airlines selling miles for less than 5 cents when mileage runs are costing more in many cases? Why not simply buy 100,000 miles?

I know I must be missing something?
