Southwest Airlines Promo Code for 30% Off
Now through May 8, 2025, Southwest flyers can use the promo code “SUNNY30” at checkout to save up to 30% off the base fare of revenue or award flights.
While there are potentially deals available for Rapid Rewards members, travel is only valid on certain days of the week and requires a 21-day advance purchase, which can make it challenging to find a discounted fare that works for you. Plus, Southwest is known to avoid discounting its cheapest fares, which defeats the purpose of a promo code.

How Effective Is This Southwest Airlines Promo Code?
Southwest has released so many promo codes lately that it’s hard to keep track. While the airline often limits these deals to higher-priced fares, that wasn’t necessarily the case this time. On most routes we tested, the “SUNNY30” code applied to the lowest available fares. The catch is that finding a true 30% discount is difficult, but you’ll generally see savings between 20% and 30%.
To highlight an example, the code successfully applied to the cheapest fare available from Myrtle Beach (MYR) to Orlando (MCO), deducting $30 off of a $126 cash price. This amounts to a ~24% discount.
Alternatively, you can book this same itinerary for 6,500 Rapid Rewards points plus $5.60. You'll save just under 28% on the number of points required for this ticket. And you'll unlock 1.39¢ per point on this redemption, about what AwardWallet users typically redeem Southwest points for.
And this is just a small snapshot of what we're seeing. Here are a few other notable fares you can book through May 8, 2025:
- Orange County/Santa Ana (SNA) to Las Vegas (LAS) — $39 or 1,361 Rapid Rewards points.
- Los Angeles (LAX) to Dallas (DAL) — $74 or 3,438 Rapid Rewards points.
- Chicago (MDW) to New Orleans (MSY) — $92 or 3,913 Rapid Rewards points.
- New York LaGuardia (LGA) to Las Vegas (LAS) — $133 or 6,284 Rapid Rewards points.
How to Get More Southwest Points

Our Take
Southwest's new up-to-30%-off fare sale is yours to take advantage of through May 8, 2025. While there are deals to be found, the 21-day advance purchase requirement and sporadic valid travel dates still make this offer hard to redeem. But if you want to test your luck, don't forget to apply the “SUNNY30” promo code.
