I love Jet Blue. I've flown them twice now for a total of six individual planes. RDU to JFK, and JFK to California.
New planes. Leather seats. 30 plus channels of live television. Pleasant employees. (Would your son like to have his picture taken in the cockpit before we take off?) Boarding passes you can actually make sense of. Large overhead luggage bins. Plenty of legroom. And they're inexpensive. And their website works.
In terms of everything but food service, a standard Jet Blue seat is better than a business class seat on a legacy carrier.
Why can't the rest of the industry do this? And if they can't, why don't they just crawl off and die and leave Blue to manage the nation's air travel?
