They lost my luggage and have ruined first day of my vacation. Still don’t have it. I have nothing. I also paid for a seat I did not get. They changed both our seats with no notice. Will never fly this airline again.

They lost my luggage and have ruined first day of my vacation. Still don’t have it. I have nothing. I also paid for a seat I did not get. They changed both our seats with no notice. Will never fly this airline again.

The flight attendant was snarky and the flight took off very late. I know it was an issue with air traffic control and the runways in Boston, so not really anyone's fault, but very frustrating, I missed an important meeting because of rgr delay. They didn't offer headphones to watch the TV, but luckily I remembered my own and was able to enjoy watching a movie.

Flight was delayed 3 hours. No food on plane besides snacks

Nice plane, with TV, comfortable seats and leg room. Updated regularly on time changes

What's not to like? Value?definitely. Every JetBlue member was extremely friendly on this flight. Very very nice new-ish aircraft,plenty of room. GOOD coffee. Entertainment,I didn't need it,but I think its available. What to do better? Well,there's nothing we can do about the other people, unbelievable how some folks are operating. Just don't allow people to lug all their stuff onto the aircraft. 1 bag. That's it. Be easier for you too. I personally would enjoy more options in schedule. One flight in and out a day is warranted given the local,I understand, but the times are inconvenient. Again, I completely understand why it is that way,It would however be great to have different options.

Had to wait over an hour in line for a Jet Blue agent to appear at the the counter. Ended up a customer service agent from another airline lines helped to check us in, and boarding pass,

The flight was delayed for more than 3 hours the flight attendant was so angry, it was my first flight with JetBlue but i don’t think I flight with them again.

The plane was late to leave.. Internet was lousy. TV was not working. when we arrived, We stayed on the plane for a long time before we got to the gate. It took us a long time to retrieve our luggage because they didn’t know what carousel to send them to. It was a bad experience.

Seats were not too comfortable; it was impossible to locate the underseat power outlet.

It was too hot in the cabin. The AC did not help.
