When you are trying these kind of system exploits, it really helps to not have to deal with any humans. It would be very easy for this plan to be shut down by

  In practice, I suspect the reps earn commissions on rentals, incur no penalties at all for the frequent flyer bonus, and were quite happy once they'd satisfied themselves that the payments would be made and the cars were only going to be driven by the renter and would be returned in one piece. The risk of some auditing process, computerised or otherwise, highlighting the error and not actually crediting the miles is still pretty high though...

  Yes and no. In this case, it seems like it helped that he dealt with humans (who gave him 1 car do go back-and-forth with instead of insisting he hand it and get another one, who organized the paperwork, ...), but it could have equally gone in the other direction.

  That is what I found great about this story. He calls 'em up and is frank about what he's doing. One quote says it all, "25 years at Avis and I've never seen anything like this" Not only did they know, but they thought it was cool and helped the guy max out his opportunity. The object lesson here is to never underestimate the impact of boredom or just the chance to be part of something unique as motivators. Bet those people had an interesting day, and you know they all got to talk some about where they live, where he lives, etc... Heck, I would jump on something like that just for the conversations that day, if nothing else. As long as the guy is nice, why not?
