Southwest launched a new airfare deal yesterday and it has the potential to be an excellent offer. By using promo code BDAY you can save up to 50% on base fares, but there are a few hoops you might have to jump through.

Quick Thoughts

If you find eligible flights when using promo code BDAY, that doesn’t mean you’ll save up to 50% on the total cost. That’s because the code only discounts the base fare, not any of the taxes and fees associated with your flight.

There are quite a few other terms to bear in mind with this promotion. The first is that you need to book on their mobile site or using the Southwest app. If you prefer using desktop though, there is a workaround. If you go to this link, that’s like booking on their mobile site and so you’ll be able to see the discounts available if applicable. Just be sure to enter the BDAY promo code when conducting your search.

When doing a search, you should see the lower price beneath the pre-discounted price which is struck through. For example, this is what it looks like for Phoenix to San Francisco on September 12. As you can see, there are several discounted flights, but it should be noted that not all of them are that day.

Southwest promo code BDAY PHX-SFO

The cost of award flights with Southwest are tied to the price of a cash ticket. That means that when there are promo codes lowering the cost of airfare, the award pricing drops accordingly. Here’s those same PHX-SFO flights when booking with Rapid Rewards points when also using the promo code:

Note that you have to book by June 13 and that travel has to be between August 6 and December 18, with a bunch of blackout dates thrown in for good measure.

Interestingly, I didn’t see the mobile/app stipulation in the terms (and it seems to work on the desktop site now)


There is a stackable offer to earn 10X Rapid Rewards points on Southwest purchases on their cobranded cards (up to $500) from June 10 – 18. If you have fall or winter travel could be a great deal!

Or better yet, purchase a ticket that is just a little bit less than the one you want with the SW Rapids Rewards Visa for the 10x, then cancel it and get it refunded as a travel credit so you pocket the 10x. Then use your travel credit to book the ticket you want and pay excess cost with the Ritz Card! Boom! You just got 10x bonus on top of your SW point AND you got trip delay/interruption insurance!

Is this one of the Chase offers? Must be targeted; I don’t see it on mine.

Had to hunt for this offer – found it on southwest.com after I logged in and scrolled down on my account page.
