others have pointed out the QF award angle...
I just thought I'd chime in here for those of us who might not want to purchase thousands of dollars worth of miles... there's also something small that all of us can use:

2,500 starpoints for $59.95 subscription

$50 Avis Gift Cert = 2,500 starpoints
So, when all is said and done, you'll get a subscription to InsideFlyer for a net cost of $9.95... I think we can all swing that
