Southwest Is Offering Up to 40% Off Flights, Including Points Bookings

Southwest has a new sale that could cut the cost of a fall or winter trip, whether paying with cash or points.

Through October 22, Southwest is offering up to 40% off select flights for travel from November 9, 2026, through March 3, 2027. That covers nearly four months of travel, including some dates around Thanksgiving, Christmas, and New Year’s.

The discount also applies when booking with Rapid Rewards points. So if a discounted flight normally costs 15,000 points, for example, the sale could bring that price down along with the cash fare.

Southwest’s 40% Off Sale

There’s no promo code to enter. Southwest automatically applies the discount to eligible flights. It’ll show the discounted base fare alongside the original price.

• Book by: October 22, 2026
• Travel from: November 9, 2026, through March 3, 2027
• Discount: Up to 40% off select base fares
• Cash and points bookings: Eligible
• Interisland Hawaii flights: Excluded

There are some restrictions, particularly around busy holiday periods.

For travel within the continental U.S., blackout dates include November 28–29, December 26–28, and January 2–3.

Flights from the continental U.S. to international destinations, Hawaii, St. Thomas, and San Juan have additional blackout dates around Thanksgiving and Christmas. The same applies in the other direction.

Not every route or flight will be discounted, either. Southwest says seats, days, and markets are limited, and the discount applies to the base fare before government taxes and fees.

This Could Make a Fall or Winter Trip Cheaper

The best part of this sale is that it isn’t limited to cash tickets. Southwest prices flights in both dollars and Rapid Rewards points, and eligible points bookings get the promotional discount, too.

That makes it worth checking any fall or winter trip already in the works.

Trips already booked are worth checking, too. Southwest says the promotion applies to new reservations rather than changes to existing ones, but eligible flights can be canceled and rebooked at the lower price. If the new points price is lower, the difference goes back into the Rapid Rewards account.

Do note that the booking window is super short. The sale ends October 22, so there’s just a few days to see whether the discount works for you.
