Southwest or AirTran coupon codes?

Just wondering if anyone knows anything about these? There is a place on both sites to put in a coupon code, but I've never seen one anywhere - just wondered if you had any ideas on that?!

I've only seen codes for vacation packages not just air only. Although My Coke Rewards was selling an air only code at one time not sure if they still are.
