Bear with me as I'm a bit of a BMI DC noob...

Just seen a thread in mileage run deals for what appears to be a mistake price for Hertz rentals http://www.flyertalk.com/forum/showthread.php?t=813074

I know that booking via flybmi.co.uk will get me a total of 1700 miles, is there any way to boost this?

I don't have any status with Hertz, but could easily be swayed from moving my car rentals from Budget as the mileage earning sucks (50 per day), but their California one way rates are great (~16 GBP per day)

Thanks 21J
