Note: Today’s show is a rerun. It originally ran in February 2014. It’s cheap to fly on Spirit Airlines, but you have to pay extra for perks. And by perks, we mean a bottle of water or space in the overhead bin. It’s totally rational: pay for what you use, don’t pay for what you don’t use. And it’s increasingly popular: Spirit is the fastest growing airline in America. And yet lots of people really don’t like Spirit Airlines. In a Consumer Reports survey published in 2013, Spirit finished last among U.S. airlines. How is the fastest growing airline also the least popular? On today’s show, we fly Spirit Airlines to Florida and ask the CEO.
