I LOVE the commercial for Ding!, with the guy jumping over all the cubicle walls and falling over people's desks when he hears the Ding!
In general, I love Southwest. Almost anytime I fly to and from school, I try to fly SWA. I can usually manage between $49-79 one way using internet fares, and that's usually a direct flight too. The alternative is to fly Delta or something right out of Daytona Beach, which saves me from having to commute to Orlando, but it means I have to make a stop in Atlanta, and be charged a minimum of $300, often it's much higher than that. Hooray for low-cost carriers!
