Delayed for three hours. This seems to be CAL’s MO when flights aren’t filled until they fill it. Business class is nice but not luxe like other airlines. Lots of space and amazing staff.

Delayed for three hours. This seems to be CAL’s MO when flights aren’t filled until they fill it. Business class is nice but not luxe like other airlines. Lots of space and amazing staff.

Boarding the flight was smooth and the flight was not full so i had an extra seat essentially

There was no flight. They canceled the flight with no knowledge to me, and I still haven’t received a refund

The flight could'nt be better ,the comfort ,the crew and everything was good.i will definitely fly with this sirline again.

I love my entire experience. What I love most, was the friendliness and helpfulness of the staff at check-in and that of the crew on the flight. Their Customer Service was paramount.

The flight crew was extremely hospitable, though there was a lot of turbulence, they made it a good experience. The only negative was the inflight experience for economy class. There wasn’t any, or at least non that I was aware of.

I liked the crew and Culture. However, my seat was too narrow and not too comfortable

When I booked my flight I choose a seat which was the window in the middle of the aircraft. My seating was change without notice and I was in the middle seat which cause me anxiety. Hated this whole flight experience

From the point of checking in I felt as if the agents and crew were like family and friends. The best customer service experience I ever had.

To be honest I did not like anything there because the flight was delay and poor customer service!

Both ways the people in the rear section of the plane were forced to check their carry on bags. I would understand this if the size and number of bags were not limited, but I do not understand why there is not room for one small overhead bag per person, even if the flight is full. I could watch the baggage handlers loading the extra luggage from my window and I’m pretty sure mine wouldn’t have survived undamaged, even though it is new and sturdy.

You sent me a confirmation yesterday for a flight reservation today that I never made. What is going on?????

Mostly good, flight take off in time and land earlier I can’t ask for more..

The plane was FREEZING COLD. Like I was wishing I'd brought gloves. Is this how JetBlue sells more blankets? Other than that, all fine. Crew just as nice as usual. A flight attendant asked (who? The pilot?) to have the air turned down for a great number of passengers who were as cold as I was. They (again -- who is "they") did not.

Flight was fine, but I was annoyed to have to pay for luggage again. We had paid for our luggage on our first two connecting flights with SATA Azores Airlines, but had to pay for luggage again with JetBlue at JFK airport. For one trip we paid over $500 for two suitcases to travel from Azores to San Francisco.

Uncomfortable seat. No help for my disability. Staff refused to help me put my carry-on in the overhead bin. So I had to check the bag.

Terrible. Quality has gone down significantly. Plane was delayed. No instructions from the staff. Will try to avoid in the future!

The plane was filthy and worn - the seat pockets were stuffed with tattered food and torn pamphlets. The cleaning crew that came on as we were deboarding were grabbing handfulls of trash and perfunctorily wiping down tables with dishrags. It's been a while since I flew Jetblue and it used to be a great experience. After this flight I will avoid flying Jetblue again if there is any alternative.

JFK is the worst airport and JetBlue is the worst airline

Very poor help no one answering a question regarding seating. Very rude staff. They don’t care, as if it’s not part of their job. Flight was delayed for no good reason and no apologies given.

Seats are getting smaller and smaller. In flight movies are poor compared to other airlines. Food is mediocre.

Our trip to Spain turned into a stressful ordeal with cockpit issues and FAA air traffic disruptions. Our American Airlines flight from Raleigh to JFK was delayed nearly four hours, causing us to miss our connections to Madrid and Jerez. We were left stranded in New York with children, even running out of diapers while trying to sort everything out. American refused to cover hotels or rental cars, leaving us to arrange and pay for them ourselves. The delays also disrupted our prepaid rental car reservations in Spain. It was a frustrating and expensive start to a family trip we had spent months planning.

Very cold on board it was like having 16hours sitting in a fridge

Old dirty plane but great lie flat seats in business class

A crew member's attitude towards a couple passengers who couldn't speak English was rude. Just because they didn't understand what the passenger said, they were not given any snack.

Great. Clean. Seats comfortable. Food was free. Had new release movies.

The boarding crew was very helpful with a little special problem I had. The inflight crew - so-so.

They kept us on the tarmac for 6 hours after already delaying our flight by 2 hours. No one had any answers. They sent our gate checked stroller to baggage claim instead of giving it back at the gate.

There was a big delay and I missed my connection flight

I don’t like the music section but I believe it was a cost decision. I changed my flight last minute due to work issues and had to sit way in the back. The seats were way closer together than I would have preferred.
