I know the Hertz discounts, the problem is they pull the 'you used a discount CDP' trump card when you ask why you on got 500 or 1200 bmi miles instead of the 1700 you are entitled to

For normal rentals I would use a magic 40% off CDP I got a while ago from a friend. It doesn't qualify for even 500 miles in any FFP, but the rentals count toward Presidents Circle requal. Of course there are the occasional incidents when I get 1700 bmi miles for such rentals

This 23.36$ rental will just sit in the HLE yard and returned on sunday morning with 1-2 miles driven.
