Agree 100% with pinniped. Actually the FFP's are probably the most profitable part of the airlines today, at least the big six that have been drowning in debt as of late. They sell so many miles and get the money right away, they regulate the use of the miles with capacity controls, and I would not doubt that many miles never get used or get used in a fashion that does not give them much value. Some people actually burn 50k for a domestic ticket worth under $300, can you believe that?
