Horribly rude check in at airport, worst in 25 years of flying. All over a simple issue they could have googled to resolve.

Horribly rude check in at airport, worst in 25 years of flying. All over a simple issue they could have googled to resolve.

1) No pilot available for 1 hour 2) no room for most passengers careyon in overhead—-> stowed below 3) when we landed we had to wait 45 min. Before docking at gate as gate was not ready

The ride share experience in JFK is terrible. After traveling on a flight, then you need to take a subway to the last stop to get an uber or lyft. Unacceptable. Bad job JetBlue for permitting JFK and Port Authority to do this to your passengers.

Four plus hour flight delay in New York caused us to take off after 11:30pm. We didn’t arrive at our hotel until five hours after check in. Started the trip off feeling exhausted.

I don’t usually fly budget airlines or airlines in the United States. It was as good as any other airline. The seats are comfortable and the airline attendants are not rude & surly. Very nice flight (s).

They have the most inexperienced / rude flight staff I’ve encountered

I paid extra for a seat closer to the front. The TV didn’t work at all for the entire flight. Would have been nice to know before I purchased an “upgraded “ seat

Too many long delays with JetBlue. Worst major airline that serves JFK but unfortunately I keep going back because of the prices.

flight cancelled after 2 delays. left us sitting in JFK at 1am. no customer service to assist rebooking.

To not have food or proper snacks on a 5 hour flight was the worst.
