Quick Thoughts

Southwest sales like this usually require that you add a promo code, but this latest sale has eliminated the need for that. As usual though, not all flights are eligible; even on routes and dates where some flights are discounted, others might not be. You’ll know if they are discounted because the original price will be struck through and the discounted price will be displayed below in green.

Also similar to Southwest’s normal sales, this discount is applicable on award flights booked using Rapid Rewards points too.

If you have any existing Southwest flights booked, be sure to reprice those to see if this sale will lower the cost of those too.
