If you are going for something that would qualify as a weekend (Thursday through Monday), Hertz has some excellent discounts on their website right now. Low rates combined with a free day or $25 off make weekend rentals pretty cheap with Hertz. If you aren't on a weekend, a lot of other companies will beat Hertz price-wise.

Hertz typically wins my business because of their service. However, as airports where all rental companies share the same buses and parking lots, I'm more apt to look at a Payless or Advantage if I can save a bundle. Rental car companies give out so few FF miles that I don't even factor that into the decision anymore.
