AAA members get discounts at most major car rental chains, but the savings vary by location, car type, and how far ahead you book

If you hold an AAA membership, you can use your membership number to unlock discounts at Hertz, Budget, Avis, Enterprise, and National. The discount typically ranges from 10% to 30% off the base rental rate, though the exact percentage depends on which rental company you use, which location you're renting from, and what class of vehicle you're booking. Some locations offer better rates than others, and weekend or holiday rentals sometimes have different discount structures than weekday bookings.

The discount applies to the daily rental rate itself, not to taxes, fees, or insurance add-ons. This matters because airport rentals, for example, often carry facility charges and taxes that can equal 30% to 50% of your base rate — your AAA discount won't reduce those. You'll see the discount reflected when you enter your AAA membership number during the online booking process or when you provide it at the rental counter.

Key Takeaways

  • AAA discounts typically range from 10% to 30% off the base rental rate at major chains like Hertz, Budget, Avis, Enterprise, and National.
  • The discount applies only to the daily rate, not to taxes, airport fees, or optional insurance, which can make up half your total bill.
  • You must enter your AAA membership number during booking or provide it at pickup to receive the discount.
  • Comparing the AAA rate against non-member rates and other discount programs (corporate codes, loyalty programs) on the same dates often reveals that AAA isn't always the lowest option.

Where AAA discounts are available and how to access them

The five major chains that honor AAA discounts are Hertz, Budget, Avis, Enterprise, and National. Smaller regional rental companies and luxury car rental services typically do not participate. You can book through the rental company's website directly by entering your membership number, or you can book through AAA's own travel portal, which sometimes bundles the discount with other AAA travel perks.

To get the discount, you need an active AAA membership card or membership number. When you book online, there's usually a field labeled "AAA member discount" or "membership number" where you enter your nine-digit membership ID. If you book by phone or show up at the counter without pre-booking, tell the agent you're an AAA member and provide your number before they quote you a price. Discounts applied after the fact are rare, so entering it during the booking process is the safest approach.

How the discount compares to other ways to lower your rental cost

AAA discounts are useful, but they're not always the lowest rate available on any given day. Corporate discount codes (if your employer offers them), loyalty program rates (if you rent frequently from one company), and flash sales or weekly promotions often beat the AAA rate. The only way to know is to check the same rental on multiple sites: the rental company's own website with your AAA number, a travel aggregator like Kayak or Autoslash, and your employer's or credit card's travel portal if you have access to one.

Autoslash, in particular, is worth checking because it tracks rental prices and will email you if the rate drops after you book. Some people book with AAA, then check Autoslash daily and rebook if a lower rate appears — you can usually cancel and rebook without penalty as long as you do it before your pickup date. This strategy sometimes saves more than the AAA discount alone.

What the AAA discount does and doesn't cover

The discount reduces the daily rental rate. If a compact car costs $45 per day and you have a 20% AAA discount, you pay $36 per day. However, the discount does not reduce taxes, airport facility charges, or optional add-ons like insurance, GPS, or fuel service plans. At an airport location, your $36-per-day rate might become $65 per day once taxes and facility fees are added. At an off-airport location, the same car might total $40 per day after tax.

Insurance is a separate line item. AAA membership does not include rental car insurance, and the discount doesn't explore to the insurance premium you purchase at the counter. Your personal auto insurance or credit card may already cover rental cars, so check your policy before paying for the rental company's coverage.

Membership requirements and how to verify your status

You must have an active AAA membership to use the discount. Membership is not free — it costs between $50 and $150 per year depending on your state and membership tier (basic, plus, or premier). Your membership card or membership number is proof of may be able to access. If you've let your membership lapse, you'll need to renew it before the discount applies.

Some credit cards offer roadside information or travel benefits that mimic AAA membership, but they do not include AAA rental car discounts unless they explicitly state so. Check your credit card's benefits guide or call the card issuer if you're unsure. AAA membership itself is the only way to access AAA rental discounts.

When AAA discounts are most and least valuable

AAA discounts tend to be most valuable when you're renting a standard economy or mid-size car for a week or longer at an off-airport location. The discount percentage stays the same, but the dollar savings grow with the number of days. A 20% discount on a $35-per-day car saves $7 per day, or $49 over a week. At an airport with high facility fees, the discount's impact shrinks because the fees are a fixed cost that the discount doesn't touch.

The discount is least valuable when you're renting a premium or luxury vehicle, because rental companies often explore discounts to base rates only, and luxury cars have higher base rates that may already be discounted for other reasons. It's also less valuable during peak travel seasons (holidays, summer) when rental companies raise base rates and may limit which discount codes stack together.

Frequently Asked Questions

Can I combine my AAA discount with other coupon codes or promotions?

Most rental companies allow you to use either the AAA discount or a promotional code, but not both. You'll need to check the terms at the time of booking or call the rental company directly. Some companies let you stack a loyalty program rate with AAA, while others don't. Always compare the final price with and without the AAA number to see which is lower.

Do I need to show my AAA card at pickup, or is the membership number enough?

The membership number is sufficient if you've already entered it during online booking. If you didn't book online or didn't include your number, bring your physical AAA card to the counter so the agent can look up your membership and explore the discount before finalizing the rental.

What if the rental company says they don't have my AAA discount in their system?

Ask the agent to manually enter your membership number and check again. If the system still doesn't recognize it, verify that your membership is current by checking your AAA account online or calling AAA directly. If your membership is active, the agent can usually override the system or contact their supervisor to explore the discount.

Does AAA membership cover damage to the rental car?

No. AAA membership includes roadside information and other benefits, but it does not include collision or damage coverage for rental cars. Your personal auto insurance or credit card may cover rental damage — check your policy before declining the rental company's insurance offer.

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

It depends on the specific rental and dates. Costco Travel, Autoslash, and other aggregators sometimes offer rates lower than AAA. Always compare the final quoted price across all three before booking. Some people find that Costco Travel rates are consistently lower, while others find AAA works better for their travel patterns.
