Terrible and im avoiding them in the future. My initial flight was delayed causing me to rebook my flight and when speaking with the representative to rebook I explained this is the second time my flights were delayed and they did nothing to help me. I wasn't booked to comfort plus or given a voucher or anything. I was almost late for my meeting that I needed to attend on Monday because of the games delta played delaying my flights even more and putting me in the very back of the plane next to an extremely intoxicated passenger

Although the flight left late, we arrived early. It was one of the quickest boarding and off boarding experiences I’ve had. It was kind of annoying the only drinks they had were water, coffee, and tea. The flight was very smooth, temperature was just right, and flight attendants were friendly.

Seats were really tight and the seat belts did not give enough slack.

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

Customer service at the gate in the flight was exceptional. On time. Aircraft and seat was decent. Thanks Delta. 💗

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

The woman in seat 1A was allowed to bring a dachshund dog onboard. It smelled terrible and the odor wafted throughout the first class cabin. This was clearly not a service dog and should be prohibited. I paid for the highest class of service, and this was a disservice. Why is Delta allowing this? I may reconsider my future flight choices.

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

It was reported to the passengers that Delta failed to schedule the crew properly. This error caused the pilot to show up about 30 minutes late. All in all Delta's inability to take care of this basic function resulted in about an hour delay.

Loyal Delta traveler, but last nights flight was a train wreck. Seated in 1B after multiple delays. Then we couldn’t takeoff because of an issue with the passenger that was ‘not in compliance’ and had to deplane along with the threat if they did not deplane, all the passengers would be required to do so. Finally they were escorted off, but the experience threw off the crew. Disruptive for everyone. Service was a mess, televisions didn’t work, bathroom door kept swinging open during the entire flight whenever empty …

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

leg space better than expected. two washrooms for one plane isn't enough.

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

The tv monitor in front of my seat was not responding. The flight crew reset it and it still didn’t work.

Maybe add a seat trade app for flyers that didn’t get seats together

There's just no way to sit fully upright and comfortably in these seats. There needs to be 2 more inches of room, and that's not something that only one person on the flight needs - the whole flight needs 2 more inches of room. If that means you sell 6 less seats, so be it. It's too close for anyone. Forcing people to pay for "premium" economy just to get "barely enough space to breathe" isn't really an answer to that.

Everything good until we waited for jet bridge at SFO. Then pilot gets on speaker & said it won’t reach plane- too short, need to go to different gate. Then 5 min later, adjusted plane/jetbridge & all ok?!?

I was forced to check my carry-on backpack despite there being space - but it came out on the baggage carousel so fast it didn't even delay my pickup. Otherwise a good flight. Boarding began early (which was disadvantageous for me) but fine.

Delays from united along with Newark air space caused delays. But an average flight! Unfortunately we come to expect delays from the airlines.

The check-in process is not the best They should have agents in site to help with any problem especially a rebook. Why does one have to get on the phone when there were at least 8 agents around that could have help?! Flying is stressful as it is and having someone willing to do their customer service will ease some of the stress.

Excellent. Although they used to greet me as a mosaic member and provide a free drink, early boarding helps me to keep coming back to JetBlue.

No music app working: no economy meal on five hour flight; hour on tarmac at the end waiting for a gate. Flight itself was smooth and easy.

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.

The flight crew that we had in our section may have been tired or something. I asked the flight attendant about my son’s screen not working and she spoke down to me like I was stupid. He still had no working screen throughout his flight. The other members had no personality and seemed like they were annoyed when you asked them for something. Definitely took a hit for simple things on my JB experience.

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

Som delays but overall we almost made it on the original time.

There were five broken seats on the plane. The crew was very rude in telling people they had to get off the plane and get a flight the next day. No call for volunteers, but telling people they had to get off. One woman was flying with her elderly mother and daughter and was told she had to leave or all three had to leave. Fortunately, a volunteer offered to stay. The situation was handled poorly.

Delays on all NY flights. There was no communication on why but they didn’t say it was weather. Other carriers were not delayed.

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

They cancelled our flight without warning OR a refund. Never doing business with American Airlines again! This is the second AA booked trip in a row that we've had challenges with.

It was so bad it will be my last. Connecting flight gate agent closed the door in my face when i told her my husband is 30 seconds away (and we were running close/late because the preceding AA flight was slightly delayed. We had to be rebooked on a non-direct flight with an overnight layover in Phoenix. This is the worst experience ever and for no fault of our own. The flight we were trying to get on would not have been late if the gate agent allowed my husband to get there. It was senseless, cruel and very upsetting. I don’t understand why we were subjected to this.

I got bumped due to weight restrictions even tho there were empty seats on my flight. I got put on an other flight with a stopover. My flight that originally was going to take 5-6 hours ever up being 14+ hours and my luggage arrived to my destination without me because I was made to check in my luggage on my original flight when I was deemed ok to board only to be asked to deplane. Worst flight experience.

I was pleasantly surprised with an upgrade at boarding. I finally had a mostly gluten free food options and a very attentive attendant.

Staff at the gate were incredibly rude, hostile and threatening. Never fly American Airlines.

AA had a nationwide tech glitch today and after two connections snd hours of delay, I arrived 7 hours late to my destination

Flight attendant walked away once they landed and we were forced to wait another hour after an already 3hr delay.

Flight was delayed a bit, but that was expected (and updated), so really not bad at all for the price. Could’ve used one less email asking me to upgrade my seat; otherwise no significant complaints

My experience was okay. The flight did not offer even water without a fee. Also had to pay extra for my carry on, as I was told I had to check my bag, even though it said I had the option to carry on a bag when booking. This costed me an extra $100. Would likely not fly with Spirit again.

Seats were comfortable but dont recline at all. Checkin online was easy but didnt provide a gate until last minute. Flight attendants were very unkind, not friendly and didnt go over safety procedures in case of a crash. No free snacks or beverages, not even water.

The booking was cancelled the next day. Spirit Airlines refunded Kayak cheapflay the full amount, but I was only refunded half. Costumer service is disgusting. Be careful. You can lose your money.

Spirit airlines was extremely uncomfortable. The seats were hard.. the constant up selling (from lack of food or even water to $15 for wi fi ) was annoying. Not a recommended airlines

They are very particular about size of the bag. Mine is small bag and has wheels. Bag wheel edges are bit outside of the measurements bucket. They charged $99 as carryon bagage

The plane flew smoothly and the crew was polite and kind. We loved our flight!

The senior flight attendant was engaging, funny and made everyone feel at ease. She is an asset to your team.

Terrible-extreme delay with very little communication, plane was overfull, luggage was returned on baggage claim in filthy condition.

Needs legroom for tall people. Needs to offer a glass of water.
