Personally, I would think you are using miles incorrectly if you're getting a 1 cent value for them. It depends on the airline, but 1.5+ cents per mile is a more reasonable value.
If you are flying intercontinental, to Alaska/Hawaii, or anything but economy the value can be much, much higher.
If you only fly economy flights within the continental US, you're probably paying peanuts for flying anyway.
