Southwest Airlines is out with a new promo code, saving travelers up to 40% on flights — but only if you book soon, as this promotion ends on August 7.

With this offer, you can travel from August 2025 into January 2026. Whether you’re flying within the U.S. mainland, to Hawaii, or to international destinations, you can knock up to 40% off the price.

Here’s everything you need to know about Southwest’s latest promotion.

Be aware that the eligible travel dates vary by destination, and the sale only applies to flights booked directly with Southwest. Seats, days, and markets are limited, so make sure to check the full terms and conditions when booking.

Remember, Southwest has an easy-to-use Low Fare Calendar to help you find the cheapest dates when your travel plans are flexible.

Since Southwest Rapid Rewards is a revenue-based program, sales also apply to flights booked using points. Unfortunately, you won’t get outsized value: expect to get around 1.1 to 1.5 cents per point from your Rapid Rewards points.

If you use one of Southwest’s co-branded credit cards to pay for your tickets, you could earn 2 to 4 Rapid Rewards points per $1 spent on your Southwest purchases. These cards also have other perks like anniversary bonus points every cardmember year, EarlyBird Check-In certificates, and more.

Hot Tip:

This sale doesn’t apply to existing bookings, so if you find your same flight is now available at a lower price, you can book it and cancel your existing reservation. Here’s how to change or cancel a Southwest flight.

Recap on Recent Southwest Changes

Remember that Southwest recently introduced basic fares (to replace the previous Wanna Get Away) and ended its popular “everyone gets 2 free checked bags” policy on May 28, 2025. Now, the number of free checked bags you’ll get, if any, depends on what credit cards you hold and whether you have elite status with Southwest Airlines.

Final Thoughts

Southwest is having a flash sale on select routes, advertising up to 40% off flights if you book by August 7 and travel through early 2026.

Remember that the cheapest fares now book into Southwest’s Basic fare type, and the airline applied its new baggage policy to all bookings made after May 28, 2025. That means you will not qualify for free checked bags when booking the cheapest tickets, and that’s worth considering as you look at ticket prices.
