Here’s the slightly tricky part, though, so listen close. If you use Skyscanner’s flight search, you won’t see results from Southwest Airlines. That’s because Southwest doesn’t allow third-party websites to show their prices 😔

So, if you want to see prices from Southwest specifically, don’t use our homepage. Come to this page instead. Here, you’ll always be able to find the latest deals from Southwest with a quick click. Want to book one of the deals you see? You’ll need to go to the Southwest website to do so. But, hey, at least we cut out the time-consuming part — which is actually finding Southwest promo codes!

Quick Facts on Southwest Promo Codes

  • Southwest promo codes are basically online coupons. So long as they aren’t out of date, they work exactly like in-store coupons, saving you money on flights.
  • These promo codes usually appear in emails and newsletters, rewarding regular customers for their loyalty. And you can also find them here, on this regularly updated page.
  • To use a Southwest Promo code, buy your tickets as usual — but, at checkout, fill out the box marked ‘promo code’. Hey presto! You’ll get a discounted price.
  • Not all Southwest promo codes get you a percentage or dollar discount. Some can be used for upgrades instead (like extra legroom).
