For those of you who subscribe to Click 'n Save email alerts from Southwest Airlines, you might have received a one-time use promo code today for 25% off your next flight purchase. If you didn't receive a promo code but need one, I'm giving away mine right here in this post!
The 25% discount is for one-time use only, and applies to the total amount of a round-trip Wanna Get Away Fare purchase before taxes and fees. Purchase must be made between March 17 and March 18, 2012, for travel between April 10 and May 16, 2012. Blackout dates apply system-wide on April 15, 2012, and for travel to/from Florida from April 10 - April 16, 2012, and on May 6, 2012. . If any portion of travel falls on the blackout dates the discount will no longer apply. Changes made to the itinerary after purchase may eliminate qualification for this promotion.
And here is my one-time use promo code for anyone who would like to use it: STJJCY2HT7. If anyone else still needs a promo code, I recommend going to this Flyertalk thread and asking nicely... perhaps someone who doesn't need theirs might be willing to share with you.
EDIT: Sorry, looks like the promo code has been redeemed.
