Yes, you can use American AAdvantage miles to book Hertz car rentals. This is done through the AAdvantage Car Rental portal on the American Airlines website, where your miles are converted to a discount on the rental cost. However, it's often not the most valuable way to use your miles. Typically, you'll get a redemption value of around 1.0 to 1.5 cents per mile, which is lower than what you can achieve by redeeming for flights. For the best deal, it's wise to compare the cost of using miles against simply paying cash, especially when Hertz has a promotion.
The process is straightforward. You log into your AAdvantage account, navigate to the 'Cars' section, and enter your rental details. The system will then show you options to pay with a combination of miles and cash or entirely with miles. It's crucial to book through this specific portal; you cannot directly tell Hertz at the counter that you want to use your AAdvantage miles.
To illustrate the value, here’s a comparison of what a typical mileage redemption might look like for a one-day rental of a midsize car:
| Rental Scenario | Cash Price | Miles Required | Approximate Value per Mile |
|---|---|---|---|
| Standard Daily Rate | $65.00 | 6,500 miles | 1.0 cent |
| Weekend Special Rate | $45.00 | 3,500 miles | 1.3 cents |
| Weekly Rental | $350.00 | 28,000 miles | 1.25 cents |
Before you commit, always check for any current promotions. American Airlines and Hertz frequently offer bonus miles for cash rentals or discounted mileage redemption rates. If you have a large balance of miles and need a car for a short trip, it can be a convenient option. But for most travelers, saving miles for award flights, where they can be worth 2 cents or more each, is a smarter long-term strategy.

Absolutely, it's possible. I use my AAdvantage miles for Hertz rentals occasionally, but only when it's a real steal. I just checked for a weekend trip, and they wanted 5,000 miles for a day. I did the math—that was only like a $50 value. I'd rather save those miles for a flight. My advice? Always compare the cash price first. If the rental is cheap, just pay for it and earn the miles instead of spending them.

You can, but the value isn't great. I see it as a backup option. If you're short on cash and have a huge pile of miles sitting around, then sure, go for it. The process is simple on the American website. But for most people, those miles are better off being used for even a short domestic flight. I only consider it if the math clearly works out in my favor, which is rare.

Yeah, the system lets you do it online. You go to the American site, find the car rental section under your account, and pick Hertz. It'll show you how many miles you need. It's convenient, but I always feel like I'm not getting the best deal. It's perfect for when you just need a car for a day and don't want to touch your bank account. Just don't expect your miles to stretch very far. Paying cash during a sale is almost always cheaper.

It's a handy feature for AAdvantage members, but it requires a bit of strategy. The key is to be flexible and compare rates. I look at the cash price, then see how many miles are required. If the value per mile is over 1.5 cents, I might consider it. Otherwise, I pay cash and pocket the miles. Also, don't forget to add your AAdvantage number to the rental reservation to earn miles on the transaction, even if you ultimately pay with cash. It's a small way to get a little extra value.
