For $85 roundtrip from Chicago to Orlando, they can have a wooden barrel strapped onto their shoulders. Face it, Southwest is the Greyhound of the sky. If you're looking for a "classy" airline, look elsewhere and pay triple or quadruple the price. All I want is FAs with proper safety training...if they give me a beverage, that's a plus. I'm more concerned about a mechanically sound plane that will get me there as close as possible to on time, and SW definitely accomplishes that.
And personally, I prefer the casual look. I was sad when ATA FAs went from their "vacation airline" garb to a more businesslike look (and it obviously didn't help them, since they went bankrupt shortly thereafter).
