Warning - do not rent from National Car Rental - airport. I recently rented a car from them, was booked since December 2013. I received my invoice with a total amount due at counter on it. When I returned the car they tacked on an "other" charge of $67.00. No where in my contract did it say anything about this charge will be added on. They said nothing we can do, it's the airport security charge! WHAT? Two days prior I rented from Budget for 2 days since I had arrived early and they didn't charge me this so called "airport security fee"! Very bad business, I should have at the very least been informed when I rented the car at the desk this charge would be added on. I will NEVER rent a car from National again.
