What is the FALL40 code for Southwest?

Customers save 40% on qualifying base fares1 by using the promotion code, FALL40, when purchasing on Southwest.com® for travel between Aug. 16, and Nov. 5, 2022.



In the context of 2025-2026 travel, Southwest Airlines frequently uses seasonal promo codes like "LUVFALL" or "FALL40" during their flash sales to offer up to 40% off base fares. These codes are typically valid for a very limited booking window—often only 72 hours—and apply to travel during the "shoulder season" between late August and early January. In early 2026, a similar promotion used the code "ONBOARD" for up to 30% savings. It is important to note that these discounts usually exclude taxes and fees and often have significant blackout dates, such as the weeks of Thanksgiving and Christmas. To use such a code, you must enter it in the "Promo Code" box on the Southwest website or mobile app at the start of your search to see the discounted "Wanna Get Away" or "Wanna Get Away Plus" fares.
