Southwest has launched a new sale today that offers 40% off select routes and dates this fall when using promo code FALL40. With award pricing being linked to paid rates, that means a reduction in the cash cost also results in a reduction in the number of Rapid Rewards points needed to book an award flight.

  • Discount availability may vary by destination, flight, and day of week, and won’t be available on some flights that operate during very busy travel times and holiday periods.

  • Discount is valid on new reservations only.
  • Discount will apply only for select flights booked within the Booking Period while supplies last for travel flown within the Travel Period.
  • Changes made to the itinerary after purchase will eliminate qualifications for this promotion and will result in forfeiture of any promotion code savings.

Quick Thoughts

On the face of it, getting a 40% discount is an awesome deal, especially with how high airfare is right now around the country. However, this deal isn’t as amazing as it first appears because it’s only valid on select routes and select dates.

Not only is it only valid on flights from August 16 to November 5, it seems to only be on select dates within those dates and only on select routes. What’s somewhat helpful is that on the landing page above there’s a dropdown where you can select your departure airport to see which destinations are eligible for the FALL40 promo code.

I tried a bunch of city pairings and dates to find eligible flights and struck out on all of them until checking Las Vegas to Colorado Springs in September. If there aren’t eligible flights on your routes/dates then you’ll see a red box at the top saying there’s an error, but if you’re successful there’ll be a green box saying the promo code has been applied. You’ll then see the original cost of the flights struck through, with the reduced pricing being listed below.

With reduced cash cost comes reduced points cost, so there are some great award redemption opportunities too if you can find availability.

Seems to work very well for intra-California flights, I rebooked 4 legs I had within that time frame and was able to get the discount on each of them.


I just booked SMF to OGG for 2 for a little under 41000 Southwest points and $22.40 🙂 I had won those points last year in a Southwest giveaway prize.


-Did not work when trying to boodk EUG-PIT via DEN
-But worked if I book each leg separately (EUG-DEN, and DEN-PIT)


found some DAL to LGA mid august


thx Stephen
