Rental cars at this airport are extremely expensive. To save a lot of money I found that renting from an in town location even with return to the airport can easily save 40% or more. The trick is to reserve before with the in-town location take a cab to the location. The cab may cost $25 to $35 but the savings can be much greater. I rented a Hertz mid-size car for 9 days with an AAA standard discount and saved $300 compared to the airport price same rental same discount card! Another point about this airport if you're traveling economy on Delta watch out! On my trip Delta had no curb check-in for baggage and the "self-check" inside the terminal had a line with about 200 people. Extremely annoying even if you've "checked-in" by Internet beforehand.
