We had same disappointment today. The chain delays on one flight, 2.5hours, then 3 hours, then 1h 50min. Excuse was weather conditions even 2 flights to same destination left on time in front of our eyes. The crew has no knowledge about what was going on. The airline is booking people on flights and changing without hesitation and not caring about the impact on the people. We are still in airport at 1am waiting since 5pm (flight was supposed to leave at 7pm and we were told to arrive 2h before.) 7 hours delay with no understandable explanation and still saying that it is due to bad weather while there is no current delays for several ours. I, myself will protest this corrupt airline and will go back to my previous airline, at least they are honest. Jetblue is not dependeble. Hope goes down in US aviation history, they do not match the expectation, they do not provide what they promise.
