Personally, I love JetBlue. I don't fly enough to earn elite status with other airlines to cash in on upgrades, first class, etc. So I think JetBlue is a great airline for the occasional flyer. Free checked bag, free snacks, DirecTV, XM radio, and no involuntary bumps. Crewmembers are super nice and they have excellent customer service, imo. For a transcon flight, I would recommend getting the Even More Space seats because it is way more comfy. For a shorter flight, I wouldn't bother since it's like $35 extra.
