after landing, we stay 2 hours on the taxi way before reaching the gate The airline and the crew were good though

Everything was on time. I was disappointed by the front section female, African American flight attendant. I did not see her name tag or would have identified by name not race. As passengers moved to the bathroom early in flight, she would say with a disdainful tone “I have to say the seat belt light is on” then go back to her book. Better trained flight attendants say something like be careful the seat belt light is on.

The price of the tickets isn't matching the flight experience. No matter how long the flight is, you're only getting pretzels. The flight attendants looked unkept and over it.

My flight to Chicago left and landed early. My return flight left two minutes late and arrived 2 minutes late. My seat selections were ideal! There were no snacks going to Chicago and no snacks on the return trip. There are no charging outlets on board.

WiFi on the flight was not working. Thus, entertainment options were limited.

Gate agents were informative and friendly… flight attendants were as well. Had a fun time chatting about their legacy AirTran experiences as a former fan of the airline that Southwest acquired.

Flight was awfully bumpy and landing was a bit jolting. I was in the restroom when snacks and drinks were served and was not asked if i wanted any. I had to ask for water finally.

Crew was great flight was great baggage claim was a failure. It took over 1 hour for bags to arrive. Poor communication poor effort when I spoke to the supervisor about the delay

Planes are aged. The wifi is unreliable and on many fights, no-existent. The flight attendants were very good.

I had a wonderful flight, but the only thing that annoyed me was how crowded TSA was. I still believe airports and all planes work together to bunch everyone together to drive up cost.

For a 69 year old with health problems I had the worse experience, no wheelchair when I entered a lady told me to sit and wait while a gentleman told me I had to walk to the Delta station, which I did. I had a carry on and a bag, and I was traveling with my service dog, which was on his carrier and the lady charged me for my carry on luggage, beside all the waiting cause of the delay, I had to walk to get my luggage cause no wheelchair showed up, I am so disappointed. I will get in touch with the company. I got home at 3:00 am, not good for my health situation.

Did not know my son and I had different seating arrangements. He was fine, but it was disappointing.

My flight was canceled after being rescheduled for four days canceling my trip. Kayak and everyone affiliated with it I.e the airlines, and just fly have been excruciating to deal with. My trip to visit family had to be canceled as there was no way to make it. I am furious at all of you.

They delayed our flight because of bad weather in NY which was completely understandable. Then they cancelled our flight and a later flight that evening. The earliest we could fly was the next morning. We ended up buying last minute tickets on another airline and made it home slightly delayed but safely that evening. Delta kept saying it was weather related but if that was the case how did we make it back on another airline? The weather in NY was cloudy but not bad.

I like for how they process during check in. It was very smoothly.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

Great overall. There was a bit of turbulence so they could only serve water because too much turbulence for the carts. Was glad they prioritized safety though

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

The captain gave good announcements and the flight attendants were friendly. The WiFi was pretty good. The plane itself looked very old inside and the seats were very uncomfortable. The screens in the seat backs were the smallest I’ve ever seen. There were so many loud and obnoxious kids on this flight and the parents didn’t do much to try to quiet them down. Some had videos and games on tablets with higher than necessary volume going the whole time.

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

Spend hours delayed with no food, water anything sitting on the aieplane with no ability to eat or use the restroom. My entire experience was the absolute worst. I will never fly jet Blue again.

It would have been nice if they had offered more than one set of snacks

Flight was delayed several 3 hours - no reason was given and no communication what so ever.

No overhead baggage room even though I was seated in row 2. Consequently had to check in my carry on bag. Baggage carousel was jammed. Took 45 min to get my bag.

Cancelled flight with no specific instructions to get a boarding pass for another flight. The whole flight of people were in line for an hour because there was only 1 person to help at the desk. This was unusual for JetBlue.

Except for the 28 minute delay leaving and the earlier reschedule to a later takeoff time the flight was good.

Loved the leg room and tvs screens on the seats and free WiFi. Wish the price was lower and could save by rebooking

The flight was delayed for 4 hours. Once onboard the crew was wonderful.

It was very difficult to stretch my knee out and I am very short. I also had a torn tendon in my knee which made it extra uncomfortable anyways. My husband is 6'2" and I can't imagine him flying in that plane.

Flight was cancelled 3 hrs AFTER etd. Thetefore Missed connection from JFK to New Zealand . No accommodation provided… This cost ne aporox 1000 USD in extra expenses and turned whst should have been a 24 hr trip ftom Boston - New Zealand into a VERY expensive , late 70+ hr nightmare … Complete nonsense!!!

Overall fine, but the delay was annoying and the reasons for the delay were not communicated. The crew on board were phenomenal!

It was one of my worst flight ever. First they were changing the gate for at least 4 times, changing from gate D7 to D12 to D44. Considering the size of the Miami Airport, we are talking about long distance and the train at the airport was not working. Then the flight was delayed around one hour. Then finally we boarded into the plane and when everybody was seated, there was an announcement that there is an issue with one of the tire of the plane, so we all had to get out of the plane with our belongings, to replace the tire. So we had around 2.5-hour delay

Whenever a passenger purchase a ticket his advantage number should automatically to his information. It's not everyone remember the number. You request for your number and American airline agent say they will email it....and they never email anything and you loose your mileage just because you don't remember your number. It should automatically go your information and associate with your email account at all times

I was late from Jacksonville, FL but the limited interaction I had with the Philly crew was great.

The delays and cancellations kept me stuck in Miami for an additional 24 hours, and the whole thing seemed extremely disorganized

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Cabin felt crammed Snacks are lame But crew was super efficient getting us out on time despite delay

The flight to Tokyo AA61 took off about two hours late, but then had to turn back. By that time the crew had to be replaced. Then they kept promising to take off in an hour, then in 3, then switch to the next day.

Boarding in Orlando was not good. Giant mob at the gate, should have been lines.

My flight was delayed by two hours which made it so that I would miss my layover flight. I stood in line for customer service for over an hour and when I reached the agent she told me to scan a QR code and it'll give me options. I wasn't offered any help, guidance or compensation, only told that I have options but that I had to figure it all out myself. I was refunded part of the trip and had to buy an expensive same day ticket from another airline in order to get home. I will never fly Frontier again.

The confirmation # CK8GNW and my name was not recognized/in Frontier system. I was able to check in on Frintier app so i went to the Frontier ticket agent, at time they told me that my name/ confirmation did not show up as a purchased ticket. I had to purchase a new ticket that cost $289.00 one way.

Although an hour and a half early was told by staff at check in they had overbooked and could not check us in for the flight.

The crew was delayed because they came on another flight that was delayed due to weather 10pm flight left at 1.30 am The airline made no effort to align alternate crew

Worst airline experience. They were rude and kept changing our seats and/or giving our seats away so our family didn’t get to sit with each other. Almost everyone we dealt with at both airports with this airline was rude. The app kept giving us wrong information making things take longer. Dealing with them before TSA can take close to an hour…longer than I’ve ever had to deal with before. Never using this airline again.

Seats are uncomfortable but price is good. Guess I can put up with misery for four hours.

Cancelled and declined to find alternatives Earlier flight is 2 days later Sent the cancellation notification very late, wish I knew earlier would have stayed to watch the Miami open final game Very disappointing service

They switched my flight to Spirit, Never using Kayak again,

The flight itself was ok and the pilot was very communicative. However, our flight was delayed for almost 3 hours, the gate was changed 3 times and there was no communication as we were waiting. The flight staff was overall a little crabby...I understand as they probably had a long day but we all did.
