As someone who's just as interested in the business of airlines as the actual passenger experience, I have to say I'm duly impressed with the way F9 reivented itself over the past year. From bankruptcy to sought-after sale in record time, more airlines could benefit from their record. I believe this was a rare case of an airline cutting costs and then doing a pretty good job of passing those savings on to the customer. There is a huge market for no-frills flying, and Frontier has written the book on it. To them, I say congratulations
