I'm a big jetblue fan.
I've flown on many other airlines, and jetblue is my favorite. More room, less major schedule changes, head-rest tvs, price, and great staff are the reasons. I notice a difference with the flight attendants on jetblue compared to other airlines...like they really like their job and love their airline. That good attitude makes a positive difference.
I liked Song, but then they stopped many flights, and they made A LOT of schedule changes.
I have tickets to California, and deliberately chose to fly into Long Beach instead of LA just so I can fly jetblue. I'd go nuts for 5 hours on a plane with no personal TVs!
