More so than in some of the other forums, the JB forum is infected by a few individuals who devote hundreds of hours and thousands of words to continually posting negative sheit no matter the topic. They do it under the pretense that they're simply revealing the "reality" of JetBlue, but nobody who spends so much time on this forum lives in reality. You won't find a reasonable answer to your question here. Try finding a few JB pilots and asking them about their experiences in person/over the phone.
