Southwest Airlines Code Checks, Day by Day

Every Southwest Airlines code check from the last 14 days, plotted by the day it ran. Green is how many came back working. Red is how many southwest.com would not accept. That is the checkout testing you did not have to sit through yourself.

where this data came from:
340 shoppers reporting back125 automated cart runs

340 of these results came from shoppers telling us whether a code worked; the rest come from automated checks and the other sources above. Last confirmed working on . Codes that stop clearing get pulled off this page automatically.

What These Numbers Mean

A code check is one result for one code. Most are our agents applying it to a real cart and reading the order total before and after; the rest come from tracked orders and from shoppers reporting back, as broken down above. Worked means the code was accepted and the total went down. Would not apply means southwest.com refused it on that cart. That is not the same as the code being fake. The usual reasons are:

  • It expired or the store switched it off after it was published.
  • It was single-use and had already been redeemed.
  • It only covers certain categories, brands or individual products.
  • The cart did not reach a minimum spend.
  • It is limited to new customers, a first order, or an email sign-up.
  • It cannot be combined with an active sale or another code.
  • It is tied to a different country, currency or membership.

So a code that failed one check can still work on your cart, and the success rate (checks that worked divided by all checks) is best read as how easily Southwest Airlines discounts apply in general, not as a verdict on any single code. Hover any bar in the chart to see that day on its own.

How We Verify Southwest Airlines Codes

Nothing goes up here on trust. A Southwest Airlines code is collected, applied to a real southwest.com cart, dated the last time it took money off an order, scored on what came back, and pulled once it stops clearing. Promotions have no code to run through a checkout, so those are dated when they go live and dropped when they lapse. Here is how far that has got on this page, and every change the agents logged along the way.

Help Other Southwest Airlines Shoppers

Not every Southwest Airlines code reaches us from the store. 2 codes on this page were first submitted by shoppers. They have also sent back 340 checkout results in the last 14 days, telling us which codes worked on a real cart and which came up empty. Wherever a code comes from, it still has to pass the same cart test before it goes up here.

Have a code we missed?

Send it over and the agents will run it through a real southwest.com cart. If it works, it lands here with the test behind it.

Did a code work for you?

Open any Southwest Airlines code above and tell us whether it worked. It takes one tap, no sign-up, and a code that keeps failing gets pulled off the page.
