Need a getaway this spring or summer? Want to use up some of your Southwest Rapid Rewards points (or Chase Ultimate Rewards points) instead of cash? This new Southwest award sale is for you.

Southwest just launched an amazing promo this week, discounting all flights within the continental U.S. by 25% when redeeming points including the entire summer! That brings flights this spring, summer, and early fall down as low as 2,000 points each way maybe even less! The only big caveat with this Southwest award sale is that only flights within the continental U.S. are eligible Hawaii, Mexico, and the Caribbean are off-limits.

Best of all, this promo covers flights all the way through the end of September, with just a handful of blackout dates. But you'll need to hurry to book: This promo expires at the end of the day next Monday, April 15.

Already have a Southwest flight later this year you booked using points? Cancel it and rebook it with this sale to save some points!

To get searching, head for Southwest.com and enter the promo code SAVE25NOW on the homepage or just head to this page with the promo code all ready for you. You'll see the discount automatically reflected in almost any route you search. You'll still pay the same mandatory government taxes and fees, though that's just $5.60 each way on these domestic flights.

With Southwest, how many points you need to book a flight is firmly tied to the cash price: the cheaper the fare, the fewer points you need. With a 25% discount, Southwest is essentially rolling back its recent devaluation for a limited time only.

For example, you can book flights from Minneapolis-St. Paul (MSP) to Denver (DEN) for under 7,000 points roundtrip with this sale. That's just the tip of the iceberg: Nearly all Southwest flights within the continental U.S. are much cheaper with this sale.

Thrifty Tip: Southwest isn't on Google Flights, so use the Southwest low fare calendar to find the best deal. But then you'll need to re-search and re-enter your promo code this 25% promo code disappears when using the low fare calendar.

Don't have Southwest points? Southwest is a Chase transfer partner, which means you can instantly send points from cardslike the*chase sapphire preferred* or the *chase sapphire reserve*Chase Sapphire Reserve® direct to your Southwest account!

Sales like this one are one of the reasons why we love Southwest. And remember: You get two free checked bags on every single fare for free. Plus, Southwest allows free change and cancellation on every ticket yes, including these award fares booked with Rapid Rewards points.
