15% Southwest Airlines discount code for Signature Visa

Update: This offer is expired. You can find the current offer details here.

Southwest is offering a 15% off code for those with a Signature Visa credit card here. Any card which says “Signature Visa” on it will qualify (for many of us, that would be the British Airways Signature Visa), and it is good for any “Wanna Get Away” fare. The ticket purchase must be made by April 30, 2011, for travel by June 1, 2011.

(Tip of the hat to MilesQuest)


  1. I tried my “Visa Infinite” cards issued in Canada and it generated 15% coupon code. I guess they are equivalent to the “Signature” cards?

  2. I have a Visa Signature (UA Mileage Plus) and I just tried it three times. I keep getting the error “Secret Token is Null”… wtf does that mean???

  3. Patrick, since WN does not have change fees, you can cancel your existing itinerary, book the new one with the discount code, and use the value of your cancelled tix to pay. The residual value is good for one year from date of original issue. (But the nicest WN feature is going away soon – you can no longer use your travel credits to pay for someone else’s travel.

  4. Does anyone have a valid code? I no longer have my Visa Signature and am trying to surprise my nieces with a trip to Vegas for their 21st birthday.

    Please help.
