Southwest Airlines bumped nearly 32,000 passengers in the quarter, more than any other airline. They are unique among major airlines in the manner in which they sell on-line. You could blame the computers or the distribution, says Nick Bredimus, an airline consultant. But ultimately, Southwest is the way it is because of its business philosophy.  "Southwest is a unique airline," he says. It goes beyond the peanuts and soda served to passengers, the first-come, first-served boarding, or the crew's irreverent attitude, inspired by Southwest's legendary chief executive, Herb Kelleher.
