I have a few codes worth $25 off a Southwest round trip fare. If you're looking to book a flight soon, $10 basically gets you $15 back. Here are the terms and condition: $25 discount valid for one-time use at southwest.com or SWABIZ.com off the total amount of a roundtrip Wanna Get Away Fare purchase before taxes and fees. Purchase must be made between September 1, 2011 and December 5, 2011, for travel between September 8, 2011 and January 30, 2012. Blackout dates apply November 22 through November 29, 2011, and December 15, 2011 through January 2, 2012. If any portion of travel falls on a blackout date, the discount will not apply. The discount is only valid with the provided Promotion Code and is not combinable with other Promotion Codes or fares available exclusively through the web tool DING!. This promotion includes only Wanna Get Away Fares. 7-day or more advance purchase may be required. Discount is not valid on reservations made using Rapid Rewards points. Changes made to the itinerary after purchase may eliminate qualifications for this promotion.
