Here’s a pretty intriguing idea on Flyertalk, it’s really not for everyone and likely not for me — too much effort involved! — but it’s one person’s story of how they’re earning over 100,000 frequent flyer miles through rental car bonuses.
The best thing about the thread is that it pointed out to me a bonus I hadn’t realized was out there, 1700 bmi miles per rental at Hertz. bmi mileage isn’t the easiest to earn, and it’s really quite valuable. Several of the other promos have been mentioned here at View from the Wing in the past, but never with the idea of spending 45 days renting cars just for the miles!
