Earlier quoted context omitted.
People who compare Southwest to Frontier and Spirit are not serious people. Southwest is a premium offering, if folks want to ride cattle car a la carte, I encourage them to, just don't ruin the established brand of SWA. I would rather fly dead on Southwest than alive on another domestic carrier.
First I've heard of southwest being a premium option. Even Wikipedia lists it as a budget airline.
