I flew Jetblue for the first time a few weeks ago LGB-JFK roundtrip and really liked it. As a frequent AA flier I'm used to no food in coach, limited legroom, little to no entertainment, and crabby flight attendants. I found none of that on Jetblue. The live TV was great and flying out of Long Beach was a breeze.
I'll still fly AA the most as I like the elite perks particulary for irreg opps and international travel, but I'll definitely be flying Jetblue again in the future.
