Large airlines might have come close to perfecting price discrimination by creating an incredibly complex pricing system designed to fill as many seats as possible. But once the Internet made it easier for flyers to compare fares, the strategy fell apart. Southwest Airlines founder Herb Kelleher said, "The high-fare, last-minute, walk-up business customer" is "gone forever." Kelleher is referring to what economists would call
