Southwest Deal: Save 20% on Your Flights

Time to save some points on new Southwest flights! Get 20% off flights using their special code for flights through end of May!

It’s Tuesday so that means a Southwest sale – except this one is a bit of a twist from the normal sales. Today, it is about a straight discount on the airfare instead of a varied discount according to route.

Southwest Discount Details

  • Use code SAVE20NOW in the promo box to save
  • Get 20% off the base fare
  • Must book between 3/14-3/16
  • Travel by 5/24/2023

This deal technically does not work on existing tickets since you cannot add the promo code to your reservation when trying to “change” the reservation. So, instead, book a new reservation that matches your current one and then cancel the old one (if you have the points to do that). It is possible to save some points. On a previous reservation I booked during a sale, I was able to save another 2,500 points if I did it this way.

But, you can also just book outright new reservations with this code and you could save some  points from yesterday’s prices.
