Doesn't jetBlue now have 16 A320s? I though they are getting them at a rate of something like one or two a month. I don't think many people realize how efficent jetBlue really is. Leather seats don't cost as much as people think (hey, Southwest is installing them on every plane in thier new fleet-renewal), and the costs of not having to serve hot meals far makes up for the costs of PTVs. And since thier A320s are equipped with over-water capability, they can do Miami-New York in just over 2 hours (my record is 2h4m), compared to the almost 3 hours it can take a Delta Express 737-200. Yes, equipping them with this equipment is a bigger investment, but, in the long run, pays offs a lot. They also don't hire cleaning crews to clean the planes, the FA's do it, another huge money-saver. And they load plans from the front and the rear (at least at FLL and PBI), which loads them, in other words, faster. And they serve the secondary airports in most cases (LGB over LAX, FLL over MIA, OAK over SFO), which yet again is a money saver.
