Just chechked Hertz Award web site and two of the awards are miles. 500 Award points = 500 miles, 1000 Award point = 1000 miles. Me I still ask for Southwest credit instead of award points if I fly in on Southwest. $45 rental today earned me one Southwest flight credit. Also, Marriot points are always awarded in addition to any other points (ailine or award club). Hertz seams to be adding more awards also. I don;t remember the upgrade award before. Check back with the website to see the latest. As an aside, you have to love Southwest, 1 roundtrip flight and car earned me 5 flight credits (2 for trip, 2 for using internet and one for car) or almost 1/3 of a free ticket for a one day trip from Dallas to Austin.
