What is the Southwest Week of WOW Sale?

It’s a four-day promotional window running June 8 through June 11, 2026. Use code FLYWOW at checkout on Southwest.com and you can get up to 40% off base fares on select flights departing between August 4 and December 16, 2026.

The “up to 40%” part is doing some work here, so don’t expect every route or date to hit the full discount. The deal also applies to the base fare before government taxes and fees. Still, this is a real, time-sensitive markdown across a wide stretch of Southwest’s network. Southwest says more than 20 million seats are included in the sale, which is not exactly pocket change in airline terms.

The discount applies in both directions on eligible routes, though availability varies by date and market. If you’ve been putting off fall travel plans, this is probably the nudge you needed.

Which Routes Are on Sale?

Southwest has called out five nonstop routes specifically, all eligible for up to 40% off:

• Baltimore and Orlando

• Dallas and Las Vegas

• Dallas and San Diego

• Austin and New Orleans

• Denver and Tampa

Those are the headliners, but they’re not the whole sale. Hawaii is also included, with fares starting around $250 one-way from California cities. Puerto Rico is in the mix too. So even if your route isn’t listed above, it’s worth checking Southwest.com directly because the sale covers hundreds of routes across the network.

The travel window runs through mid-December, which means you can shop for early fall getaways, shoulder-season trips, and some pre-Christmas travel. Just don’t expect Thanksgiving week itself to be a gold mine. Blackout dates apply, and peak holiday periods tend to get carved out of these promotions.

It’s Not Just Flights

The Week of WOW covers more than airfare. Here’s the full rundown:

• Rental cars: Save up to 25% off base rates on Dollar rentals booked between June 8 and June 15, plus earn 1,200 Rapid Rewards points on any rental of two days or more. Pickup must be through November 30, 2026.

• Hotels: Earn 5,000 Rapid Rewards bonus points or get a 5,000-point discount on select hotel stays booked now through June 30, 2027. That’s a nice little stacking opportunity if you’re building a full trip.

• Cruises: Book between June 8 and June 15 and earn 2x Rapid Rewards points on eligible cruises departing on or before December 31, 2027.

• Vacation packages: Getaways by Southwest is offering up to $500 off packages for two, based on a five-night minimum stay. Packages also include two free checked bags, which still adds real value, especially now that bag fees have crept up across much of the airline industry.

None of these require the FLYWOW code. They’re separate promotions running alongside the flight sale.

Why Southwest’s Flexibility Makes This Easier To Book

One thing that makes a sale like this easier to jump on is Southwest’s no-change-fee policy. If your fall plans shift after you book, you can rebook for a different date and only pay any fare difference. There’s no extra penalty layered on top.

That said, Basic fares come with a catch. If one leg of a round trip is booked at Basic pricing, you can only cancel if you cancel both legs or upgrade the Basic segment. So yes, it’s still worth reading the fare rules before you finalize, especially if you’re booking a round trip and mixing fare types.

For straightforward point-to-point bookings, though, the flexibility is genuinely useful. It takes some of the stress out of locking in cheap flights months ahead of time.

This sale closes Thursday, June 11, with no grace period expected. If you’re even somewhat serious about fall travel, it’s worth spending ten minutes on Southwest.com with code FLYWOW to see what your route looks like. Between the fare discount, the wide travel window, and Southwest’s flexible booking policy, this is one of the more useful airline sales we’ve seen this year.
