Promo Code for 31% Off Southwest Flights on Halloween

Please note this site has financial relationships with American Express and this post may contain affiliate links. Read my Advertiser Disclosure policy here to learn more about my partners.

Using promo code TREAT31 you can get 31% off roundtrip Southwest flights for travel on Halloween, October 31st The flights must be round trip and must include Wanna Get Away fares.  The purchase must be made between today (9/16) and 11:59PM in the originating city tomorrow (9/17).  Those flying on Southwest on Halloween also get a free alcoholic beverage!


What this means is that you could either:

A.  Fly round trip on 10/31 and get 31% off the entire price of the ticket.

B. Have your outbound flight on 10/31 and your return at a later date.  You could just get 31% off the outbound.

C. Have your return flight on 10/31 and your outbound on a previous date.  You would just get 31% off the return flight.

Option B could be handy if you want a slightly cheaper way to go watch your grandkids trick-or-treat!  All in all this deal is probably only appealing to a very small set of people since the travel has to include 10/31, but I’m sure it will help a few folks save a little cash.  As is typical with Southwest, a sale involving a promo code does not apply to points reservations.
