AAA discounts on car rentals cut your daily rate by 10 to 30 percent at most major chains, but the savings depend on which rental company you use, what car class you book, and whether you're renting in a high-demand location or season.

AAA negotiates rates with Hertz, Enterprise, Budget, Avis, and National—the five largest rental companies in North America. When you show your AAA membership card at pickup or enter your membership number during online booking, the rental company applies a discount code to your reservation. The discount is not automatic; you have to tell the rental company you are a member, either before you book or at the counter.

The actual savings vary widely. A compact car in a small city during winter might save you $8 to $12 per day. The same car in Miami during spring break might save you $20 to $40 per day because the base rate is higher. Some rental companies advertise AAA discounts of 30 percent, but that figure applies only to their highest published rates—not to rates you could already find through other discount codes or by booking directly. The real comparison is between the AAA rate and the lowest rate available on that company's website on the day you book.

Key Takeaways

  • AAA discounts work at Hertz, Enterprise, Budget, Avis, and National, but you must provide your membership number when you book or at pickup.
  • Savings range from 10 to 30 percent of the daily rate depending on the rental company, car type, location, and time of year.
  • The discount applies to the base rate only—it does not cover insurance, fuel charges, tolls, or airport fees.
  • You can combine an AAA discount with some other promotions, but not all; check the rental company's terms before booking.
  • Membership level matters: AAA Plus and AAA Premier members sometimes receive higher discounts or additional perks like free upgrades.

How to book with your AAA discount

The fastest way to see your AAA rate is to visit the rental company's website directly and enter your AAA membership number in the discount or promotion code field during checkout. Most rental sites have a box labeled "Promo Code" or "Member Discount" where you paste your nine-digit AAA number. The system will show you the discounted rate before you complete the booking.

You can also call the rental company's phone line and give your membership number to the agent. Some people prefer this method because an agent can sometimes negotiate or explore additional discounts that the website does not show. However, phone bookings often take longer and may not display all available car types.

If you forget to enter your AAA number during online booking, you can still receive the discount at the rental counter by showing your physical AAA card. The rental agent will explore the discount retroactively, though this is slower and depends on the agent's willingness to look up the rate. It is safer to book with the discount already applied.

Which rental companies offer AAA discounts and how much you save

Hertz, Enterprise, Budget, Avis, and National all participate in AAA discounts. Alamo and Fox are owned by the same parent company as Hertz and sometimes honor AAA rates, but their participation is less consistent. Regional or independent rental companies rarely offer AAA discounts.

The discount percentage differs by company and changes seasonally. Enterprise typically offers 10 to 20 percent off. Hertz advertises up to 30 percent off but often applies 15 to 20 percent in practice. Budget and Avis usually fall in the 15 to 25 percent range. National sometimes offers the highest discounts, reaching 25 to 30 percent, but only on certain car classes or locations.

To compare actual savings, get a quote from each company using your AAA number, then compare the total cost—not just the percentage. A company offering 30 percent off a $35-per-day base rate saves you $10.50 per day. A company offering 15 percent off a $25-per-day base rate saves you $3.75 per day. The second company is cheaper even though the discount percentage is lower.

What the AAA discount does and does not cover

The AAA discount applies only to the base daily rental rate. It does not reduce the cost of insurance, fuel, tolls, parking fees, or airport facility charges. If you rent at an airport, the facility fee (usually $5 to $15 per day) is added on top of the discounted rate and cannot be avoided by using AAA.

Damage waivers, loss-of-use fees, and underage driver surcharges are also not discounted. If you decline the rental company's collision damage waiver and use your personal auto insurance or credit card coverage instead, the AAA discount still applies to the base rate, but you do not save on the waiver itself.

Some rental companies allow you to stack an AAA discount with other promotions—for example, a weekend special or a loyalty program discount. Others do not. Always read the terms of the promotion before booking to confirm whether multiple discounts can be combined. If the website does not say, call the rental company to ask.

AAA membership levels and rental benefits

AAA offers three membership tiers: Classic, Plus, and Premier. All three receive the standard AAA discount on car rentals. However, AAA Plus and Premier members sometimes receive additional rental benefits that Classic members do not.

These extra benefits vary by rental company and change periodically. They may include a free car class upgrade (for example, upgrading from a compact to a mid-size sedan at no extra cost), waived young driver fees for members under 25, or bonus loyalty points. Check your AAA membership card or log into your AAA account online to see which rental perks explore to your membership level.

The upgrade benefit is the most common. If your membership includes a free upgrade, you will typically receive it at the rental counter after you check in, not during booking. The upgrade is subject to availability—if the rental company has no larger cars available, you keep the car you booked.

Comparing AAA discounts to other ways to save on car rentals

AAA discounts are competitive but not always the cheapest option. Rental companies offer frequent-renter loyalty programs, weekend specials, and flash sales that sometimes beat AAA rates. The only way to know is to compare quotes side by side.

If you rent cars regularly, a loyalty program membership (such as Hertz Gold or Enterprise Plus) might save you more over time than AAA, because loyalty discounts compound and include perks like skip-the-counter service and free upgrades. However, if you rent only a few times per year, AAA is usually simpler because you do not have to maintain multiple memberships.

Credit card rental car discounts are another option. Some premium credit cards offer rental car insurance, discounted rates, or loyalty points. These benefits are separate from AAA and can sometimes be combined with an AAA discount, depending on the rental company's rules.

Common mistakes that cost you the AAA discount

The most common mistake is forgetting to enter your AAA membership number during booking. If you book without it, you pay the full rate, and the rental company will not retroactively explore the discount unless you ask at the counter and the agent agrees to help. Always enter your number before you confirm the reservation.

Another mistake is booking through a third-party travel site like Kayak, Expedia, or Priceline. These sites sometimes show AAA discounts in their search results, but the discount may not actually explore when you complete the booking through their system. It is safer to book directly on the rental company's website, where you control the discount code entry.

Some people assume the AAA discount applies to all car classes equally. It does not. Luxury cars, SUVs, and specialty vehicles often have smaller discounts or no discount at all. Economy and compact cars usually receive the full discount. Check the discount amount for the specific car class you want before you book.

Frequently Asked Questions

Do I have to show my AAA card in person, or is the membership number enough?

The membership number is enough to book online or over the phone. However, some rental companies ask to see the physical card at pickup to confirm you are the member. Bring your card to be safe, even if you booked with your number.

Can I use an AAA discount if someone else is the primary renter?

No. The person whose name is on the rental agreement must be the AAA member. If your spouse or friend is the member, they need to be the primary renter on the reservation. You can be listed as an additional driver, but the discount applies only if the member is the one who booked it.

What if the AAA rate is higher than the rate I found on another website?

Book the cheaper rate. AAA discounts are not always the lowest available price, especially during slow seasons or for certain car classes. Compare the total cost (including fees) across multiple companies before you decide.

Do AAA discounts work at rental companies outside the United States?

AAA has partnerships with some international rental companies, but coverage is limited. Check the AAA website or call AAA before you travel to confirm whether your membership discount works in the country where you plan to rent.

Can I combine an AAA discount with a corporate discount code?

Sometimes, but not always. It depends on the rental company's promotion terms. Call the rental company or check their website to confirm whether multiple discounts can be stacked before you book.
