Great flight. Best in years. Very clean craft. Easy boarding. Communicative pilot. Friendly flight attendants. Absolutely smooth take off, in flight and landing. Very comfortable seats. Smoothest flight I've experienced in years. THANK YOU JET BLUE!

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 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.

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.

Excellent price. Everything on time. two bad parts. Kayak said I couldn't sign in for the flight online, but I got an email at the same time from Jet Blue and they let me sign in online. Second bad part was that, although I had provided my known traveler number, neither of my boarding passes, for this flight and the previous one, had TSA pre-check showing.

In-flight staff was very helpful and excellent. However, the flight was delayed by 90 minutes. Also the boarding process should be expedited in case of delayed flights. This will help the passengers trying to make international connections.

The delays were not communicated well at all. I was in the airport for over 9 hours with little knowledge of if I was actually going to reach my destination.

It was OK, but it was delayed about an hour, and my luggage didn't arrive till about an hour and a half after the flight

Another American Airlines flight, another significant delay. At least this one wasn't canceled like many others have been. This time we sat on the runway at LaGuardia for 2.5 hours. By my count that is 7 American flights the last three months that have been delayed 2 hours or more or canceled entirely.

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.

Unfortunately the flight was delayed by almost 2 hours, so I missed an appointment arriving into DFW

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

My experience was excellent for a business trip. I like the smaller jets because everyone gets either a window or aisle seat and the boarding and de-planing goes much faster. I really like the schedule American Airlines has between Atlanta and NY - lots of options. Crews are great and very accommodating. Sometimes the flights are not full and they let people move around once the boarding doors are shut to spread out.

Primary flight attendant in FC wasn't that engaged throughout the flight. All other aspects of flight were good.

On time departure & early arrival. Made a long day much better.

The flight from Buffalo to Chicago was on an older and smaller plane. Seating was tight. Looking closely at the interior of the aircraft there were definitely signs of aging and wear.
