Booking Your Car

How long will you be renting? If it's for less than a week, you'll probably do best with a major rental company, such as Alamo, Avis, Budget, Dollar, Enterprise, Hertz, National or Thrifty. For rentals of a week or longer, you may get better rates from local companies, particularly auto dealers. Remember, however, to be wary of local companies if you plan to drive a lot; if you break down or get into an accident, they usually lack the support services of the majors.

Always shop around. Check the major booking engines and aggregator sites (such as Travelocity and Kayak) to get an idea of what rates are available, but you should also visit the car rental companies' Web sites as well -- they'll often offer exclusive discounts, and you'll avoid booking fees. Don't forget to check out our selection of discount car rental deals before making any reservations.

To lower your rate, ask about discounts for any major national organizations, frequent flier programs and credit card programs you may belong to. They'll frequently offer deals on car rentals. Those offered through AAA can be very good. If you're employed by a company that frequently rents cars, they may have a negotiated rate. Make sure to check.

Before you book online, do an Internet search for coupon or promotion codes to put into the booking engine of your car rental company's site. Just type in the name of the company followed by "coupon code" into the search field and you'll often find special promotion codes that could save you anywhere from 5 to 20 percent off the cost of your rental.

If you're not already, consider joining your car rental company's loyalty program when you book. These vary by company, but most of them are free and entitle you to certain privileges when picking up your vehicle; your information will be on file ahead of time, allowing you to simply jump into the car and go rather than standing in a long line or filling out paperwork. You could also be eligible for special discounts or free upgrades.
