15% off Southwest fare with Visa promotion

I just saw this in the travel section of my Sunday paper and signed up for it. This is for Visa Signature cards only (funny, mine is an American Airlines Advantage card, but it still says VISA Signature just below the card number).

This is for 15% off Wanna Get Away fares for up to 8 people on the same itinerary. Tickets must be purchased online at Southwest.com or SWABIZ.com by April 30, with a seven-day advance, for travel through June 1.

Go to https://usa.visa.com/signaturesouthwest/index.jsp to register. They will immediately give you the one use code (and send an e-mail follow-up with the code).

Thanks

I also have a Visa Signature card but from another airlines. Was your American card okay?

Edited to add: A reply is not necessary. I tried it and was given a discount code for my card. I did not read the fine print and it is good only for a round trip. I needed a one way fare.
