What AAA car rental discounts actually cover

AAA negotiates reduced rates with major rental companies — Hertz, Enterprise, Avis, Budget, and others — but the discount is a percentage off the base rental rate, not a flat dollar amount. The actual savings depend on which rental company you use, what car class you book, when you rent, and where you rent it. A AAA member might save 10 percent at one location and 25 percent at another, or find no discount available at all on a particular date.

The discount applies only to the daily rental rate itself. It does not cover insurance, fuel charges, tolls, parking fees, or airport facility fees — those are added on top. If you decline the rental company's insurance and use your own car insurance or credit card coverage instead, you still get the base rate discount, but you are responsible for any damage or liability that your personal coverage does not handle.

AAA does not rent cars directly. You book through the rental company's website or phone line and enter your AAA membership number at checkout, or you can call AAA's travel service and they will book it for you. The discount code or member number is what triggers the reduced rate in the rental company's system.

Key Takeaways

  • AAA discounts are percentage reductions on the base rental rate only, and the percentage varies by location, company, and booking date.
  • You must provide your AAA membership number when you book to receive the discount — it does not explore automatically.
  • The discount does not cover insurance, fuel, tolls, airport fees, or other add-ons that rental companies charge separately.
  • AAA's travel service can book for you, but you can also book directly with the rental company and enter your membership number yourself.
  • Some rental companies offer better AAA rates than others, so comparing quotes across different companies before you book can save more money than the discount alone.

How to find and use your AAA discount code

Log into your AAA account online or open the AAA mobile app and look for the "Travel" or "Discounts" section. Most AAA memberships include a list of rental car partners with discount codes specific to each company. The code is usually a six to eight character alphanumeric string — for example, something like "AAA123" — that you enter in the promotional code field when you book.

If you cannot find the code in your account, call AAA's member services line (the number is on your membership card) and ask for the current rental car discount codes. They will give you the codes for each company and may also tell you which companies are offering the best rates that week. Some AAA members also have access to a travel agent through AAA who can book the rental and confirm the discount is applied before you pay.

When you book online directly with the rental company, enter the code during checkout in the "promo code" or "discount code" field. The system will show you the discounted rate before you complete the booking. If the code does not work, the rental company's website will usually say so when ready — do not assume the discount was applied if you did not see it reduce the price on screen.

Which rental companies offer the best AAA rates

Enterprise, Hertz, Avis, Budget, and National all participate in AAA discounts, but the depth of the discount and the availability vary. Enterprise and Avis often advertise AAA rates prominently and tend to offer consistent discounts across many locations. Hertz and Budget discounts are available but may be smaller or less consistent. Luxury and specialty rental companies — Alamo, Fox, or regional operators — may not offer AAA discounts at all.

The best way to know which company will save you the most is to get a quote from at least two or three companies for your specific rental dates and location. Enter your AAA membership number in each quote and compare the final daily rates side by side. A company offering a 20 percent discount on a $35 per day base rate saves you $7 per day, while a company offering 15 percent off a $40 per day rate saves you $6 per day — the smaller discount on the higher rate is still better.

Airport locations and city center locations sometimes have different discount levels from the same company. If you are renting at an airport, get a separate quote for a nearby off-airport location — you may find a better rate even after paying for a ride to the rental lot, because off-airport branches sometimes offer deeper AAA discounts to compete with airport locations.

What AAA membership level you need for rental discounts

Rental car discounts are included in all AAA membership tiers — Classic, Plus, and Premier. You do not need to pay for a higher tier to access rental discounts. The discount codes are the same regardless of which tier you hold. However, some AAA members also have access to additional travel benefits (such as hotel discounts or travel insurance) depending on their membership level, so check your account to see what else is included.

If your AAA membership has expired, the discount code will not work. Rental companies verify membership status when you enter the code, and an expired membership will be rejected. Renew your membership before you book if it is about to expire, or the rental company will charge you the full undiscounted rate.

Combining AAA discounts with other offers

You can usually combine an AAA discount code with other promotions, but not always. Some rental companies allow you to stack a AAA code with a weekend rate, a weekly rate, or a loyalty program discount. Others require you to choose one or the other. When you get your quote, the website will show you the final price after all discounts are applied, so you can see whether stacking worked.

If you are a member of a rental company's loyalty program (Hertz Gold, Enterprise Plus, Avis Preferred), you may be able to use both your loyalty status and your AAA code in the same booking. The rental company's system will calculate which combination gives you the lowest rate and explore both if possible. Again, the quote screen will show the final price, so you will know before you commit.

Credit card rental car discounts (some premium credit cards offer rental car insurance or rate reductions) are separate from AAA discounts. You can use your AAA code to get the discounted base rate and still use your credit card's rental car benefits, such as waived insurance or damage coverage. Read your credit card's rental car terms to confirm what is covered.

When AAA discounts may not be available

During peak travel seasons — summer holidays, spring break, major events — rental companies sometimes suspend AAA discounts or limit them to specific car classes. If demand is very high, the rental company may not offer any discount because they can fill their fleet at full price. You will see this when you enter your code: the system will either explore a smaller discount than usual or show no discount at all.

Last-minute bookings (within 24 to 48 hours of pickup) sometimes do not may have access to for AAA discounts. Rental companies reserve discounts for advance bookings to encourage planning ahead. If you book at the last minute, you may see a full-price rate even with your AAA code entered.

One-way rentals (picking up in one city and dropping off in another) may have different discount availability than round-trip rentals. Some companies offer AAA discounts on one-way rentals; others do not. Check the quote for your specific routing to see whether the discount applies.

Understanding what is not covered by the AAA discount

Insurance is the biggest add-on cost that the AAA discount does not touch. Rental companies offer collision damage waiver (CDW), liability coverage, and personal effects coverage — these are optional but often pushed at checkout. The AAA discount reduces only the base rental rate, not these insurance products. If you decline the rental company's insurance, make sure your own auto insurance or credit card covers rental cars, or you could be liable for the full cost of any damage.

Fuel charges, tolls, parking fees, and airport facility fees are all separate line items added after the discounted rental rate. If you return the car with less than a full tank, the rental company will charge you their per-gallon rate to refill it — usually higher than gas station prices. Some rental companies offer a pre-purchase fuel option (you pay for a full tank upfront at a set rate), which can save money if you know you will return the car empty, but this is also not covered by the AAA discount.

Additional drivers, GPS units, child car seats, and roadside information packages are all add-ons that the rental company charges separately. The AAA discount applies only to the base daily rate for the primary driver and the vehicle itself.

Frequently Asked Questions

Do I have to book through AAA to get the AAA discount, or can I book directly with the rental company?

You can book directly with the rental company's website or phone line and enter your AAA membership number or discount code to receive the discount. You do not have to book through AAA's travel service, though AAA can book for you if you prefer. Either way, the discount is the same — it is tied to your membership number, not to where you book.

What if I lose my AAA membership number or discount code?

Call AAA's member services line (the number is on your membership card or in your online account) and they will provide your membership number and current discount codes. You can also log into your AAA account online to find the codes in the Travel or Discounts section. If you cannot locate your membership card, AAA can look up your account by phone using your name and address.

Can I use an AAA discount if I am not the one driving the car?

The AAA member must be listed as the primary driver on the rental agreement to use the discount. If someone else is the primary driver, they will need their own AAA membership to receive the discount. Some rental companies allow additional drivers to be added to the reservation, but the discount is tied to the member whose number was used at booking.

Will the AAA discount work at rental locations outside the United States?

AAA discounts work at some international locations of major rental companies (Hertz, Avis, Budget, Enterprise), but availability and the discount percentage vary by country and location. Before you book an international rental, contact AAA's travel service or check your account to see whether the discount is available in that country. International rentals often have different pricing structures and may not honor US discount codes.

Is the AAA discount better than booking through a travel website like Kayak or Costco Travel?

It depends on the specific dates and location. Travel websites and membership programs (Costco, Warehouse clubs) sometimes negotiate rates that are lower than what AAA offers, or they may offer the same rate under a different name. Get quotes from multiple sources — AAA, the rental company directly, and any travel websites or memberships you have — and compare the final daily rates. The lowest quote wins, regardless of which source it comes from.
