We just got back from DW last night. Flew JB and had a great experience going, but a bit of a problem coming back. Our flight was supposed to be at 10:35 a.m.---but didn't leave until a little after 2 p.m.! It seems that there was a mechanical breakdown, some relay switch. We waited for about 1 1/2 at the gate, then they finally let us on the plane where we waited another 1/2 hour on the plane supposedly for a "fax" from JFK that said it was ok to go. Well, that turned out to be BS. It seems that there was something wrong with the avionics and they were waiting for a new part. They just didn't want to tell anyone that little fact. So they let everyone off the plane and said to check back at 1 p.m. for an update. Finally a little after 2 p.m. we got clearance to go. This is why I hate to travel. With a fearfull flyer like myself, the worse thing is having to sit at the gate for 4 hours, while they tell you there's a "mechanical" problem with the plane. I almost pulled a Rainman! That said, aside from the little white lie, the Jet BLue folks were really pretty nice. They did try to update you as much as possible, we had the TVs and air conditioning working, and access to the bathrooms. So it could have been worse. Plus, they're giving everyone free round-trip vouchers. And the flight home was just fine. Has anyone had ANY bad or semi-bad experience with Jet Blue, or did I just jinx the airline?
