Southwest’s Week of WOW Sale: Up to 40% Off Hawaii Flights

Before you scroll, I sometimes share links for Hawaii spots I genuinely recommend. No extra cost to you, it just supports the site. Read our affiliate disclosure for info.

Southwest Airlines just launched its Week of WOW sale, and if a Hawaii trip is anywhere on your list for later this year, this one is worth your attention.

The sale is live right now and runs through Thursday, June 11, 2026. Use promo code FLYWOW at checkout on Southwest.com (non-affiliate) to get up to 40% off eligible fares. Flights must depart between August 4 and December 16, 2026.

This affects anyone who has not yet locked in flights for a fall or late-summer Hawaii trip.

Which Routes Are Included and Why Some Are a Bigger Deal

Southwest has been expanding its Hawaii network throughout 2026.

Two new Southern California routes make this sale especially interesting for Southern California travelers. Ontario (ONT) to Honolulu launched on June 4, and Burbank (BUR) to Honolulu launches August 4, right at the start of the eligible travel window.

Both airports are significantly less congested than LAX. I have personally flown out of and into ONT, and it’s one of my favorite SoCal airports.

You get shorter security lines, easier parking, and far less terminal chaos.

If you live in the Inland Empire, the San Fernando Valley, or the San Gabriel Valley, these routes may genuinely change how you get to Hawaii.

Does the FLYWOW code work for all Hawaii routes?

It should apply to all Southwest Hawaii routes, but some specific flights or fare classes can be excluded during sales.

The safest approach is to search your exact route, apply the code, and confirm the discounted total before you pay.

Which Travel Dates Give You the Best Deal?

The eligible window runs August 4 through December 16. Not all dates within that window are equal. Here is a quick breakdown of how they stack up:

October and November are consistently the sweet spot for Hawaii travel.

Crowds are lighter, the weather is excellent across most islands, and the North Shore surf season on Oahu begins.

If budget is your priority and your dates are flexible, aim for that window.

Is This Sale Worth Booking Over Hawaiian Airlines?

For many travelers, yes. And the reasons go beyond just the discount percentage.

Southwest gives you two free checked bags, which matters a lot on a week-long Hawaii trip.

That is real savings compared to paying bag fees on most other carriers.

The no-change-fee policy is also genuinely useful. Life gets in the way. Plans change. Southwest lets you rebook without a penalty fee, and you only pay any fare difference.

Hawaiian Airlines has also been through a significant in-flight change recently.

They ended free meals on most Hawaii to mainland routes and replaced them with a paid pre-order dining system.

You can read about that shift here: Hawaiian Airlines Is Ending Free Meals on Most Hawaii Mainland Flights.

That change makes Southwest’s overall cabin experience more competitive on the basics than it used to be.

That said, if Hawaiian flies a nonstop route that Southwest does not serve, or if you are chasing miles in a specific loyalty program, Hawaiian may still be the right call.

The FLYWOW sale makes Southwest worth comparing seriously. It does not automatically make it the only answer.

Bottom Line: What Travelers Should Do Next

If a Hawaii trip is in your plans for August through December 2026, here is what to do before Thursday night:

Go to Southwest.com (non-affiliate), search your route to Hawaii, and apply code FLYWOW at checkout.

Confirm the discounted price before you complete the booking. If the savings look good, lock it in.

Southwest’s no-change-fee policy means you are not stuck if something comes up.

If you are planning to rent a car on Maui, the Big Island, or Kauai, the Week of WOW sale also includes 25% off car rental base rates.

Booking that now at the sale rate is worth doing even if you adjust your dates later.

The discount window closes Thursday, June 11, 2026. After that, it is gone.
