Is It Cheaper to Rent a Car at the Airport? Q: Can I save money by renting a car at the airport? A: Usually, the answer is no. Most people find that they can save money by renting a car away from the airport. Renting a car at the airport usually costs more, both in terms of the daily rate and in extra airport taxes and fill-up fees. However, if you are flying into a city, you will need to consider the additional cost of paying for transportation to the car rental agency. Also, some off-airport car rental outlets keep somewhat limited hours, so be sure to phone ahead. If you want to rent a car in your own city, there is no reason to drive out to the airport to rent a car. Chances are that you will save money if you simply look for a car rental agency that is closest to your home.
