Southwest Rapid Rewards points can be used to book rental cars directly through Southwest’s platform with eight major partners: Alamo, Avis, Budget, Dollar, Hertz, National, Payless, and Thrifty. The process involves converting points into travel funds on a fixed value basis, where 1,200 points typically equal $1 in rental value. For example, a $300 weekly rental would require approximately 360,000 points. This method often provides less value per point compared to redeeming for Southwest flights, but it offers flexibility for travelers needing ground transportation.
The value is fixed and transparent. According to industry data from frequent traveler analyses, the redemption rate for car rentals through Southwest’s portal consistently averages around 0.83 cents per point. This is a critical figure for members to assess value. In contrast, flight redemptions can regularly yield 1.4 to 1.6 cents per point, especially during peak travel times. Therefore, using points for car rentals is generally most practical when you have a small points balance insufficient for a flight, or during periods of high cash rental prices.
Booking is centralized. You must start your search on the Southwest website or mobile app under the “Car” section. You cannot apply points directly at the rental company’s counter or website. The portal shows both cash and point prices, allowing for easy comparison. Availability mirrors what’s found on major online travel agencies.
Partner-specific benefits may apply when booking with points. For instance, booking with points through the portal can sometimes include basic benefits like those from National’s Emerald Club or Hertz Gold Plus Rewards, but you must ensure your membership number is added to the reservation. It does not automatically confer elite status benefits unless you already hold status with the specific rental company.
A key consideration is cancellation flexibility. Reservations made with points are fully refundable; the points are redeposited into your Rapid Rewards account without fee if cancelled before the rental pickup time. This is more forgiving than many non-refundable cash rates.
To maximize value, follow this process: First, check the cash price for your desired rental. Second, calculate the points required. Third, evaluate if using points makes financial sense compared to paying cash and saving points for a flight. For a $250 rental costing 300,000 points (0.83 cents/point), paying cash is advisable if you have flight redemptions in mind that offer higher value.

As someone who manages a corporate travel program, I direct my team to use Southwest points for flights first, always. The car rental option is a backup. We’ve used it a handful of times when an employee had expiring points or needed a last-minute rental during a price surge. The process on Southwest’s portal is straightforward—it’s like booking with cash, but you select the points option at checkout. The main perk for business use is the full refundability. We’ve changed plans last minute and getting the points back instantly was hassle-free. Just remember, it won’t earn you additional rental loyalty points.

I’m a budget-focused solo traveler, and I look at points as another form of cash. I always do the math. Last spring, I needed a car in Denver. The cash rate was sky-high, but my flight was on points. I checked Southwest: the rental was 50,000 points for a compact. I calculated that was about a $415 value based on their going rate. Paying cash would have wiped out my fun budget. So I used the points. It was worth it for that specific trip because the cash prices were inflated. My rule? If the points redemption gets you more than 1 cent per point in value compared to the local cash rate, and you need the car, go for it. Otherwise, save them for a flight.

For families, using Southwest points for a minivan or SUV can be a move during school breaks. Rental prices for larger vehicles jump dramatically in summer and around holidays. We booked a 7-seater through the Southwest portal with points last Christmas. While we used a lot of points, the alternative was paying over $800 cash for the week, which we didn’t have in the budget after buying flights. The booking included all the standard insurances you can choose from. Just book early—the inventory for larger vehicles on the points platform can be limited. It let us use our travel rewards for the entire vacation package, not just the airfare.

I view my Southwest points as a flexible travel fund. The car rental partners are a useful component of that. Here’s my practical take: The list of eight partners covers all the major brands you’ll find at any airport. You’re not getting a worse car or rate because you’re using points; you’re just paying with a different currency. The fixed value means no surprises. I once had a trip where I only needed a car for one day. I had a small stash of points that wouldn’t get me anywhere close to a flight. Instead of letting them sit, I redeemed them for a one-day rental with Budget. It felt efficient. The key is non-attachment—don’t force a points redemption for a car if the numbers don’t work. But having the option seamlessly integrated where you book your flights is genuinely convenient.
