IMO Spirit's model is the best. UAL, DAL, etc have a good model now while times are good. What happens when main street doesn't feel as rich anymore when housing prices stagnant or go down, their 401k goes down, etc? Spirit's tickets are so cheap they cast a wide net. I don't work for Spirit but as long as the company stays true to its pricing model, you will never go hungry. Eventually I would imagine you will start to take over much of SWA's business, once you start to really scale in the 300 aircraft range.
