Why all the JetBlue hate? They're probably my favorite along with Southwest.
A few years ago I was flying on Christmas day and the flight was delayed maybe an hour or two. I didn't care because they offered out free bags of Terra Blue chips and soda while we waited. Then a few days later I got an email saying they just gave me a $50 voucher towards my next flight (and the flight itself only cost $100 if I recall). I thought that was pretty awesome on their part.
I agree--I love JetBlue. Can't afford first class or business class, but I can afford those great extra room seats JetBlue offers--great idea. They are first in a lot of new customer service ideas so this is no surprise. I always choose JetBlue when I go up to Boston (but I'll pass on going up there to 70+ inches of snow)
