The most straightforward way to use Southwest points for a car rental is by transferring them to a partner loyalty program. Southwest Rapid Rewards points cannot be booked directly for rental cars on their website. Instead, you transfer your points to one of their hotel partners, like Marriott Bonvoy, and then use those points to book a rental car through the hotel's travel portal. It's not the most efficient use of points, but it is the primary method available.
Before you transfer points, it's crucial to understand the value you're getting. The conversion rate is generally not favorable. For example, transferring points to a hotel program often results in a lower value per point compared to redeeming them for flights. You should always calculate the cents-per-point (CPP) value to see if the rental car "cost" in points is a better deal than just paying cash.
Here’s a simplified comparison of potential value:
| Redemption Method | Estimated Point Value (Cents/Point) | Best For |
|---|---|---|
| Southwest Flights (Wanna Get Away Fares) | 1.3 - 1.5 cents | Highest value, especially during |
| Transfer to Hotel Partner for Car Rental | 0.6 - 0.9 cents | Convenience when you have excess points |
| Using Points for Hotel Stays | Varies widely | Can be good value with specific hotel promotions |
The step-by-step process involves logging into your Southwest account, navigating to the "Rapid Rewards" section, and finding the "Transfer Partners" option. You'll select a partner like Marriott, transfer the required points (note: transfers are often not instantaneous and may have a minimum amount), and then log into that partner's site to find their travel redemption options.
This method is best suited for situations where you have a large surplus of Southwest points and your travel plans are flexible. For most people, saving points for flight redemptions, especially with Southwest's generous no change fees policy and two free checked bags, provides significantly better value. If you need a rental car, paying with a credit card that offers primary rental car insurance is often a more cost-effective choice.

Honestly, I looked into this for a trip to Phoenix. You can't book a car directly with Southwest points. The only way is to transfer them to a hotel points program first. I did the math and it was a terrible deal—the points were worth less than half what they are for a flight. I just put the rental on my card and saved the points for my next flight. It's much simpler and you get way more for your money.

Think of it as a two-step swap. Southwest doesn't have its own car rental service. So, you exchange your Rapid Rewards points for points in a partner program, such as a hotel loyalty program. Those programs often have a "Experiences" or "Travel" section where you can redeem for a car. The key is checking the transfer ratio and the available redemption options on the partner's site before you commit any points, as the value can vary significantly.

As a dad a family vacation, my goal is simplicity and value. Using Southwest points for a rental car is possible but complicated. You have to transfer points to another company's program, which feels like a hassle. I've found it's better to use a credit card that earns points good for travel directly or just budget for the car rental cost. Save your Southwest points for what they're best at: getting the whole family to the destination with bags flying free.

This is a classic case of "just because you can, doesn't mean you should." The primary value of Southwest Rapid Rewards points is in their excellent flight redemptions, particularly when you catch a sale. The transfer process to a partner for a car rental is indirect and typically offers poor value per point. You're almost always better off paying for the rental with cash or a general travel card. Reserve your points for securing low-cost airfare, where their power is truly unlocked.
