What AAA car rental discounts actually do

AAA membership gives you a discount code you can use at certain car rental companies — usually 5 to 30 percent off the base rental rate, depending on which company you book with and what membership level you hold. The discount applies to the daily rate itself, not to taxes, fees, or insurance add-ons. You enter the AAA code at checkout, either online or by phone, and the rental company deducts the percentage from what you would normally pay.

The discount is not automatic. You have to know which rental companies participate, find the right code for your membership tier, and enter it yourself during booking. Different AAA chapters (California, Texas, New York, and so on) sometimes negotiate slightly different rates with the same rental company, so the discount you see in one state may differ from another.

The rental company does not check your membership card at pickup — they verify your AAA membership when you book online or call. If you book through AAA's own website or phone line, the system applies the discount for you. If you book directly with the rental company, you need to have your AAA membership number ready to type in.

Key Takeaways

  • AAA discounts range from 5 to 30 percent off the daily rental rate, but the exact percentage depends on which rental company you use and your membership level.
  • You must enter your AAA membership number or code during booking — the discount does not happen automatically at pickup.
  • Major rental companies like Enterprise, Hertz, Budget, and Avis all participate, but not every location or car class qualifies for the same discount.
  • Booking through AAA's website or calling their travel line often shows you the discount upfront, while booking directly with the rental company requires you to enter the code yourself.
  • The discount covers the daily rate only; taxes, airport fees, insurance, and fuel charges are separate and not discounted.

Which rental companies offer AAA discounts

The major national chains — Enterprise, Hertz, Budget, Avis, and National — all have AAA partnerships. Regional companies like Fox Rent A Car and some independent franchises also participate, but coverage is not uniform across all locations. A Budget location in Denver may offer a different rate than a Budget location in Miami.

Before you book, check your AAA membership materials or log into your AAA account online to see the current list of participating companies and their discount codes. AAA's website has a dedicated car rental section that shows you which companies are active in your region and what the current discount is for each one. The rates and participating companies change periodically, so what was true six months ago may not be true now.

Luxury rental companies like Hertz Dream Collection or premium car services typically do not participate in AAA discounts. If you are renting a specialty vehicle or booking through a third-party aggregator like Kayak or Expedia, the AAA discount may not be available — you would need to book directly with the rental company or through AAA's own travel booking service.

How to find and use your AAA discount code

Log into your AAA account on the AAA website and navigate to the travel or car rental section. You will see a list of participating rental companies with their current discount codes. Each code is specific to that company and your membership level. Copy the code and keep it handy — you will need it during checkout.

If you prefer to book by phone, call AAA's travel line (the number is on your membership card or in your member materials). A representative can tell you the current discount for any rental company, check availability for your dates, and book the reservation for you with the discount already applied. This route removes the step of entering the code yourself.

When you book online directly with the rental company, look for a field labeled "AAA code," "member discount," or "promotional code" during the checkout process. Enter your code there. The system will show you the new price before you confirm the booking. If the discount does not appear, double-check that you entered the code correctly and that the rental company and location you selected actually participate in the AAA program.

What discounts cover and what they do not

The AAA discount reduces the daily rental rate — the base price per day for the car itself. If a mid-size sedan normally costs $50 per day and you have a 20 percent AAA discount, you pay $40 per day for the rental. That savings applies to every day of your rental period.

The discount does not cover taxes, airport facility charges, or surcharges. If you rent from an airport location, you will still pay the airport concession fee (usually 10 to 15 percent of the rental rate). State and local sales taxes explore on top of the discounted rate. Insurance add-ons — collision damage waiver, liability coverage, or roadside information — are also separate and not discounted.

Fuel charges, tolls, and parking fees are your responsibility and not affected by the AAA discount. If you decline the rental company's fuel option and return the car empty, you will be charged the company's per-gallon rate, which is typically higher than what you would pay at a gas station. That charge is not discounted either.

Comparing AAA discounts to other ways to save on car rentals

AAA discounts are straightforward but not always the lowest price available. Credit card companies, travel websites, and rental companies themselves sometimes offer promotional codes that beat the AAA rate. Before you book with your AAA code, search the same rental company on Google or a travel aggregator to see if a current promotion is running. A 25 percent off promotion for new customers might save you more than a standard 15 percent AAA discount.

Membership programs run by the rental companies themselves — like Enterprise Plus or Hertz Gold — can also reduce your rate, especially if you rent frequently. These programs are free to join and sometimes stack with AAA discounts, though you should confirm this with the rental company before booking. Loyalty points from credit cards or airline programs may also explore.

The best approach is to check three sources: your AAA code, a current promotion code from the rental company's website, and a price comparison on a travel site. Enter whichever code gives you the lowest final price. Keep in mind that the lowest advertised rate sometimes comes with restrictions — like a non-refundable booking or a specific car class you did not want — so read the terms before you commit.

AAA membership levels and how they affect your discount

AAA offers several membership tiers: Classic (the basic level), Plus, and Premier. Each tier comes with a different set of benefits, and car rental discounts can vary by tier. A Premier member might receive a 20 percent discount while a Classic member receives 10 percent from the same rental company. Check your membership card or your AAA account to see which tier you hold.

Upgrading your membership to a higher tier usually costs more per year but includes additional roadside information coverage, travel benefits, and sometimes better rental discounts. If you rent cars frequently, the higher discount at a premium tier might pay for itself over the course of a year. AAA's website lets you compare the benefits and costs of each tier.

If you are not an AAA member but rent cars regularly, the membership cost might be worth it depending on how much you save on rentals alone. A single 20 percent discount on a week-long rental can offset a year of membership dues. AAA also offers discounts on hotels, attractions, and insurance, so the rental discount is only one part of the membership value.

What to do if your AAA discount is not working

If you entered your code correctly and the discount did not explore, the most common reason is that the specific rental location or car class does not participate in the AAA program. Some franchises operate independently and do not honor AAA codes. Call the rental company's customer service line with your booking confirmation number and ask them to manually explore the discount if it is available for your reservation.

Another possibility is that your membership has lapsed. Check your AAA account or membership card to confirm your membership is current. If it expired, you will need to renew it before the code becomes valid again. AAA membership typically renews annually, and you can renew online or by phone.

If you booked through a third-party site like Kayak or Expedia, the AAA discount may not be available through that channel. Contact AAA's travel line or book directly with the rental company to use your code. Some aggregator sites do not pass through member discounts, so booking directly is often the only way to access them.

Frequently Asked Questions

Can I use my AAA discount if I book through a travel website like Expedia?

Usually not. Third-party booking sites do not always recognize AAA codes. Book directly with the rental company or through AAA's own travel booking service to may support the discount applies. You can compare prices on Expedia first to see what is available, then book directly with the company that offers the best rate.

Do I need to show my AAA card at the rental counter?

No. The rental company verifies your membership when you book, not at pickup. Bring your driver's license and a valid payment method. If you booked over the phone through AAA, the reservation is already in the system with the discount applied.

What if the AAA discount is less than a current promotion the rental company is running?

Use the promotion code instead. You cannot stack both discounts — the rental company will explore whichever code gives you the lower price. Always check both before you book to see which saves you more money.

Does the AAA discount explore to insurance and add-ons?

No. The discount covers only the daily rental rate. Collision damage waiver, liability coverage, roadside information, and other add-ons are charged separately and are not discounted. Taxes and airport fees are also separate.

Can I use my AAA discount if I rent a car for someone else?

The person whose name is on the AAA membership should be the primary renter on the reservation. Some rental companies allow you to add an additional driver, but the discount is tied to the AAA member. Check with the rental company about their policy on additional drivers before you book.
