I was doing it for dollars and switched for miles. Getting a $20 or $30 or whatever check each meotn (sometimes more, sometimes less) just got deposited into the bank and that was it. With miles I know they have to be used for travel. I feel like I'm actually benefiting from the program. The other way of course I was benefiting too, jsut never felt that way because it was never enough for a big purchase or anything.

Of course, asking the question in Flyertalk may not get you many unbaised answers.
