For travelers who are still eyeing spring getaways, Southwest Airlines has launched a tempting new promotion, offering select flights with discounts of up to 30 percent across its network.

The “Splash Sale” is valid for booking until Thursday, February 29, at 11:59 p.m. PT, is applicable for travel within the continental United States between March 19 and May 22, 2024.

To take advantage of these discounts, travelers will need to type promo code SPLASH in the "Promo Code" box when doing their flight searches on Southwest's website or mobile app.

The maximum discount offered outside of California is 30 percent off the base fare, before any government taxes and fees. Here's how the discounts are structured based on the days of the week:

  • 30 percent off for Tuesday and Wednesday travel
  • 25 percent off for Monday, Thursday, Friday, and Saturday travel
  • 20 percent off for Sunday travel

Certain blackout dates from March 23 to 24, March 30 to 31, and April 6 to 7 apply, along with blackout routes. All intra-California routes, and travel to and from Orange County (SNA) are excluded from the promotion. Additionally, this sale only applies to continental U.S. routes, meaning Caribbean or Hawaii travel won't be discounted.

The Splash Sale discounts also extend to reward travel, offering an excellent opportunity for customers to redeem their Southwest Rapid Rewards points for reduced fares. For example, Travel + Leisure discovered a Tuesday flight from Phoenix to Nashville that’s eligible for this promotion, discounted from 9,991 points to just 6,993 points.

Southwest devotees can also continue to benefit from the airline's Companion Pass offer through March 11. New Southwest Chase credit card applicants qualify for the buy-one-get-one flight pass when they spend $4,000 within the first three months of opening their account.

Once travelers secure the pass, they can select one companion to fly alongside them for only the cost of taxes and fees, which amounts to a mere $5.60 on domestic travel. Don't miss out on the chance to save big on your next Southwest adventure with these enticing offers.
