Friendly crew and super clean cabin. 💺 are comfortable as well. I love the ambient blue lighting.

My main complaint is specifically with having booked through kayak. Our flight was delayed and I was no longer able to access my boarding pass through the kayak app. Fortunately I had screen capped it. If I had not it would have been critical problem while boarding.

I didn’t purchase any food on the flight or use the entertainment system, so am unable to comment on them

Delay of 4 hours, i understand there was a medical emergency, but the fact that they arrived without the medical equipment and didnt have a replacement on the airport was annoying because they told us supposedly their manager went for one replacement to JFK airport and cross the city on traffic i mean seems so unprofessional! Anyways at least the flight was safe!

The flight itself was great. Just the last leg was delayed almost 2 hours between take off, sitting on the runway, etc. Otherwise completely fine, no complaints.

The flight crew was excellent. The seats in economy were more comfortable than other flights that I have taken in economy. The only criticism that I have is the lack of food. Flying time was 5 hours and the inly food was a package of biscotti and some pretzel mix. You need to preorder food or carry it onboard.

The promised curbside wheelchair and baggage help both appeared, promptly and accurately. Check in and Security were both a breeze. We expected more comfort in First Class and we were not able to order our selected meal in advance, due to some glitch on your website. Entertainment was unavailable, at any level, except by making additional payment. At $1,000/seat, that seemed a little cheeky.

Crew was courteous respectful and attentive to request from passengers.

Right as we were supposed to be heading to JFK, they pushed the flight back three hours, with no explanation. And then they sent out a $12 food voucher (could you get any cheaper? My JFK bag of cheezits and vitamin water was $13) well past the hour anyone would have not already bought food (why didn’t they send it when they announced the flight delay?). Then, once we had finally boarded the plane, we sat there for nearly an extra hour because they were having maintenance fix a clogged toilet. And like the icing on the airline cake, we landed really hard. But maybe I was just cranky, because it was 2 AM.

Had to change our flight last minute it due to a family emergency. Customer service answered the phone right away and able to switch our flights for no extra fee. I would highly recommend this airline to all.

The WiFi has been awful on my last few Delta Air Lines flights.

Only one side of the heafphone jack work. Crew was friendly and helpful.

Typical flying experience in the US. Nothing particularly good or bad.

I was able to select a gluten free meal for my outbound flight operated by KLM but my selection wasn’t saved on Delta so I ended up not having a hot meal. The cabin crew was nice enough to offer some cheese so I could pair it with some gf crackers I had. The seat would recline but slowly but surely would come back up so I couldn’t sleep as I would have wanted to.

Forced to check my bag which fit in carry on, boarded and then sat for over an hour waiting to take off with no explanation.

7 hour delay for mechanical reasons Handled badly by crew and delta personnel

Food was not the best. Too many items had sauce pm them with a lot of spices The seat was not comfortable especially when you lay down

Flight was canceled so it was not a great experience. Boarded, then deboarded. Delayed, boarded a new plane then deboarded the 2nd plane and flight was canceled. Then booked a fight to Rome and took a train to Venice the next day. Lost an entire day +

The fight was about 2 1/2 hours delayed, but that was weather related. The flight was also overbooked. But we were in Comfort plus so the flight was fine for us.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

Communication with the customer and stay is important. Staff off with a minor inconvenience but it worked out of course. Also this was a very old Mint Class plane. They snuck this one in on us. The updated aircraft are much better.

The flight itself was fine, but the boarding process was extremely frustrating. There is no one scanning boarding passes - passengers just scan themselves and enter the jetway. By the time my husband and I got on the plane and were halfway to our seats they determined there were too many bags on the plane and everything at that point needed to be checked. This created a lot of unnecessary chaos. They should have alerted people before getting on the plane that they would need to start checking bags instead of waiting until people were already on the plane.

In flight on demand didn't work at our seats. Only a single beverage/snack run.

Traveling with JetBlue from NYC was convenient as accessing JFK airport was straightforward via the LIRR to the AirTrain. Maneuvering through the terminal was hassle-free, which was a pleasant start to the journey. However, the flight experience itself left much to be desired. The seating arrangement was notably uncomfortable; despite securing a window seat, space felt cramped. This was exacerbated by the middle seat passenger encroaching on my area, which made the flight less enjoyable. Additionally, while the in-flight entertainment system initially seemed like a reprieve, the sound outlet on my seat was inoperable. This issue turned what could have been a manageable three-hour flight into a rather tedious ordeal, as I was unable to use the entertainment system effectively. While JetBlue provided a smooth process in terms of airport logistics, the on-board experience highlighted areas in need of improvement, particularly in terms of comfort and entertainment system maintenance.

Over 2 hour delay for a 50-minute flight is unacceptable, especially in normal weather. Very poor communication via app

Kayak sent over to jet blue my account being Mike Callaghan instead of Michael. I have a jet blue account with Michael that was connected

Going through JFK’s security is a mess. The TSA security said no shoes on the bins. So, we place our shoes in the belt and they came out all over the belt. Boarding was delayed and Flight as well.

Jetblue needs to improve on Onboarding as it seems to always be behind on departing. It never leaves on time. I would recommend to have an earlier Onboarding in order to leave on time and respect your customers time as well.

I booked this flight using JetBlue points and I was just so happy. The plane was so clean, I had every need met. Thank you!!

Another horrible Jet Blue experience. This airline has suffered the biggest decline of all from best to worst. TVs didn’t work (again). internet was temperamental. Boarded late and couldn’t get organized to serve snacks.

The boarding process was incredibly slow, as was deplaning. They started beverage service and there was an extremely small amount of turbulence, so they discontinued it. They said they’d resume if possible, but even thought the rest of the flight was perfectly smooth, they didn’t bother. Getting our checked bags took longer than I’ve ever waited and they couldn’t even tell us which carousel they were coming out on, so everyone was running back and forth for 30 minutes.

It was really good. The boarding was good and smooth. They even checked our carry ons if you wanted to without any charge.

Flight was delayed , waited in the tarmac for 3 hours and then came back and was cancelled

Extreme weather delays. Missed my flight to France and I ended up leaving the plane.

I arrived to LaGuardia Airport 50 minutes prior to my 6am flight but was told that I was too late and would have to flight standby to Dallas in order reach my final destination of Jackson, MS. Hundreds of people were in my situation but the agents chalked this up to being normal for any day. Had my been able to board my original flight I would have arrived at my destination by 10:30am. I didn’t arrive until 7:30pm which included a 30 minute wait on the tarmac. Strangely my luggage arrived at my final destination at 12:30pm of the same travel day. This was by far the worst travel experience I’ve ever had.

The food was horrible compared to other airlines, there was no space for the overhead bins for carry-on luggage, and the seats were very uncomfortable.

I got food poisoning - lasted 4 days after starting medications - someone should check with food delivery.

They were not helpful in letting my baby and I rebook a flight early in the day when it was clear we were going to miss my connection (we did). The seats are much smaller than I remember. I did not get the option to board early with my toddler. I was flying solo with her and that would have been a big help.

On an overnight flight people behind me kept lively and loud conversation, which meant I couldn’t sleep. Food was really lousy, im sorry to say.

I am very disappointed with american. We have flown American airlines numerous times, as well as other airlines and never had such an experience. My son's flight for Sunday afternoon was cancelled around 11 am. We were told not to do anything bec AA would. After an hour of not seeing a change in his flight status. I called AA. I was on hold for half hour then opted for a call back. That call back never came. So I called again, in meantime I started looking online at my options. No flights were leaving that day from AA. But other airlines were flying out. We needed our son in Chicago asap.i kept calling AA for a callback, but never received one. Finally i called back later in the afternoon and a representative answered the call. She told me there were no flights out till Tuesday morning. I asked how this is possible, I had seen flights from AA and other airlines leaving Monday. She said she checked all NYC airports and there were no AA flights till Tuesday AM. Then I asked about getting on another airline. She responded i would be responsible for that. When I asked how AA would reimburse. She became nasty and told me AA has not responsibility to reimburse anything they will put me in a flight for Tuesday morning. When i explained he must be there Monday by 8am, she told me there's nothing to do and practically hung up. At that point I just asked her to book the Tuesday morning flight. I had this experience with other airlines, cancelled due to weather and they and their reps were much more helpful. Either way Tuesday morning flight was delayed as well. Over an hour! I expect more from AA.
