Southwest's biggest sale of the year is here: up to 40% off base fares with code FLYWOW. Book by June 11, 2026 for travel Aug 4–Dec 16. Here's how to stack it with points.
TL;DR: Southwest's "Week of WOW" is its biggest sale of the year — up to 40% off base fares with promo code FLYWOW. You have to book by June 11, 2026, for travel between August 4 and December 16, 2026. Only a 1-day advance purchase is required, but seats, days, and routes are limited and blackouts apply. And because Rapid Rewards award prices track the cash fare, this is quietly a points sale too: when the cash price drops, the points price usually drops with it.

It's not only flights. The same Week of WOW runs deals on hotels, rental cars, cruises (departing on or before December 31, 2027), and Getaways by Southwest vacation packages, where you can save up to $500 on a package for two.
Southwest Rapid Rewards is revenue-based: the number of points an award flight costs is tied to its cash price. So a 40%-off cash fare generally means roughly 40% fewer points for the same seat. If you have a Rapid Rewards balance, check the points price during the sale, not just the dollar price.
Don't have enough points? You can move them in at 1:1, based on our verified transfer data:
Transfers are usually quick, but they're one-way and final, so only move over what you'll actually book. Confirm the points price of your exact flight first, then transfer the amount you need.
One more Southwest quirk in your favor: there are still no change or cancel fees. Book now to lock a seat, and if the same flight drops again before you fly, rebook it and Southwest gives you the difference back as travel funds or points.
Chase issues the Southwest cards, and a couple carry strong public welcome offers right now (from our card database):
There's also a Priority card and a couple of business versions if you want lounge-adjacent perks or a bigger earn rate. If you already sit on Chase or Bilt points, transferring 1:1 beats opening a card for a single trip. And if you hold a Southwest Companion Pass, a sale fare gets even better: your companion flies with you for just the taxes and fees.
Quick gut check: a welcome bonus is only worth chasing if you'll hit the spend naturally and use the points. Don't open a card just to save on one ticket.
When does the Southwest Week of WOW sale end? Booking closes June 11, 2026. Your travel has to fall between August 4 and December 16, 2026.
