Yes, you can use Southwest Rapid Rewards points to pay for rental cars. This is done exclusively through the Southwest portal, where you can book with partners including Alamo, Avis, Budget, Dollar, Enterprise, Hertz, National, and Thrifty. The redemption value is typically around 0.8 to 1.2 cents per point, which is generally lower than the value achieved from redeeming points for flights. This option is best for travelers with a surplus of points or when rental cash rates are exceptionally high.
Booking a rental car with points is a straightforward process. You log into your Rapid Rewards account on Southwest.com, navigate to the "Car" booking section, and enter your travel details. The search results will display both the cash price and the corresponding points price for each available vehicle. You then select the rental option and complete the booking using your points balance. It's a direct transaction handled within Southwest's system.
The value proposition is a key consideration. Industry data from frequent traveler analyses consistently shows that Southwest points yield the highest value when redeemed for their intended purpose: Wanna Get Away fares. The points cost for a rental car is calculated by dividing the cash rate by a fixed value, often around 0.8 cents per point. For example, a $100 rental would cost approximately 12,500 points. In contrast, those same points could cover a significant portion of a short-haul flight.
Here’s a comparison of potential redemption scenarios for a sample $200 rental:
| Redemption Method | Approximate Points Cost | Estimated Value per Point |
|---|---|---|
| Rental Car Booking | 20,000 - 25,000 points | $0.008 - $0.01 |
| Short-Haul Flight | 5,000 - 8,000 points | $0.013 - $0.015+ |
This makes rental car redemptions a lower-value use of your currency. However, the convenience factor is significant. It allows for the consolidation of travel expenses into a single currency, simplifies budgeting by avoiding out-of-pocket costs for the rental, and can be advantageous during peak travel periods when cash prices surge.
There are important limitations. You cannot use a mix of points and cash for the rental transaction; it's an all-or-noints booking. Furthermore, the points cover the base rental rate only. All mandatory taxes, fees, surcharges, and optional extras (like additional insurance or fuel) must be paid separately with a credit card at the rental counter. Your existing elite status with the rental company or credit card benefits may not apply as they would on a standard cash booking.
For most travelers, using cash or a credit card that offers primary rental insurance is more cost-effective. But if your points are expiring, you lack cash for the rental, or you find a promotional points discount, this functionality provides a useful backup option. Always compare the points cost against the cash price and the potential flight value before committing.

I just used my Southwest points for a rental last month in Denver. It was super easy on their website—searched like normal for a car, and it showed me the price in points right next to the dollar amount. I clicked, confirmed, and got my voucher.
The thing you need to know is that the points only cover the car itself. When I picked it up, I still had to put down a card for the taxes and the mandatory fees. It didn’t feel like the greatest deal point-wise, but it was perfect for my situation because I had a bunch of points and wanted to save my cash for the trip. It’s a solid tool to have in your back pocket.

As someone who manages travel for a small team, I view this as a flexible budget tool rather than a premier redemption. The process is integrated and reliable. You receive a confirmation and a rental voucher directly from Southwest, which you present at the counter like any other reservation.
The fixed points-to-cash conversion rate means the value is transparent but static. Market data suggests you are effectively locking in a value of just under one cent per point. Therefore, I only recommend this path under specific conditions: when departmental travel budgets are tight but rewards points are available, or during a price surge where the cash rate becomes prohibitively expensive. For optimal point utilization, securing flights remains the priority.

Think of it like this: Southwest miles are really for flights. Using them for a car is okay, but not the best deal. You get maybe 1 cent per mile. For flights, you can often get 1.5 cents or more.
So, should you do it? Only if:
Just remember, you'll still need a card for the extras at the counter. It's not a completely free rental.

My perspective comes from comparing loyalty programs. Southwest's car rental portal functions similarly to most airline partners—it's a booking platform powered by a third-party, converting cash prices into points at a predetermined rate. The value is consistently mediocre across the industry.
The real utility is contingency . If your flight plans are canceled and you need to rent a car last minute during a storm, having the option to use points can be a lifesaver, even at a poor redemption rate. It turns your points into a versatile travel fund.
I advise checking the points price, then doing the math. Divide the cash price by the points required. If the result is near or below 1 cent, paying cash is smarter. Save your Rapid Rewards points for the incredible flexibility and value of their flight-based revenue-based redemption, especially when catching last-minute sales on Southwest's own routes.
