Yes, you can absolutely use airline miles or hotel points to rent a car, but it's not as straightforward as booking a flight. Typically, these loyalty programs don't pay for the rental car directly. Instead, you redeem your miles or points for a statement to cover the charge or for a gift card from a major rental company. The value you get per mile can vary significantly, so it’s crucial to compare the cost in miles versus paying cash.
The most common way to use miles is through your credit card's travel portal. Many travel rewards cards, like those from Chase, American Express, or Capital One, allow you to use your accumulated points to "pay yourself back" for travel purchases, including car rentals. You simply book the car normally, and then use your points to erase the charge from your statement.
Another method is through airline partnerships. Most major U.S. airlines have partnerships with rental car agencies. You can navigate to the "Car Rentals" section on their website and use your miles to book. However, this often provides poor value. You might get a better deal by transferring your points to a travel partner or just paying cash.
Here’s a quick comparison of common redemption methods:
| Redemption Method | How It Works | Value Per Point/Mile (Approx.) | Best For |
|---|---|---|---|
| Credit Card Travel Portal | Use points to book directly or as statement credit. | 1.0 - 1.5 cents | Good, consistent value; easy to use. |
| Airline Mileage Portal | Redeem miles through the airline's car rental booking engine. | 0.5 - 1.0 cents | Convenience if you have a large mileage balance. |
| Hotel Points Transfer | Transfer points to a partner rental agency (e.g., Marriott to Hertz). | Varies widely; often low. | Last-minute option if points are expiring. |
| Loyalty Program Gift Cards | Use points to purchase a rental car gift card. | 0.5 - 0.7 cents | Least recommended due to low value. |
Before you redeem, always do the math. Divide the cash price of the rental by the number of miles required. If the value is less than one cent per mile, you're likely better off saving your miles for a flight or a more valuable redemption.

I always check my card's travel portal first. With my Chase Sapphire card, my points are worth 1.25 cents each when I book a car directly through them. It's just like paying cash, but with points. Way simpler than messing with airline websites, and I usually get a better value. I only use miles if I have a bunch about to expire and no flight plans.

It's possible, but be careful—the value is often terrible. I once looked at using my airline miles and it would have cost me triple what paying cash would. You're almost always better off using a cashback card or a card that offers primary rental car insurance. Think of miles for cars as a last-resort option, not your go-to move for a good deal.

As a dad our road trips, I've found using hotel points can be a sneaky good deal. We accumulate Marriott points from stays, and they partner with Hertz. Sometimes, transferring a small chunk of points can knock a significant amount off the weekly rental cost, especially during peak season when cash prices are high. It's not our primary method, but it’s a nice tool to have.

The key is flexibility. Don't just assume using miles is the best choice. Pull up the rental cost on two or three different sites: the rental company's site, a travel aggregator, and your card portal. Compare that final price, including taxes and fees, to the mileage cost. You might be surprised that paying cash and earning miles on the transaction is the smarter long-term play for your loyalty account.
