Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I liked the ease of checking in, luggage check in, wheel chair assistance, boarding and flight.

The main person that was coordinating everything was a short white/light skin Spanish man and he was very rude. It honestly made me feel like it was everyone’s First day at work. His announcements were very not reasonable and they did not make sense. The stewardess on the flight that made the announcements she didn’t even know what she was talking about she sounded inebriated. There were no snacks or drinks on our flight there wasn’t even much turbulence. This flight was not enjoyable nor was it what a Delta flight should be and just this past week I flew with Delta 3 times.

nothing Delta could do... the person sitting next to me was huge and overflowing into my seat

Crew was great! I need wheelchair assistance and they knew who I was and updated me that my chair was on its way and to just hang tight. There was some turbulence but the captain announced we would be going thru it and he handled the plane well. Landing was soft and his.

Aircraft very cramped. Check-in was great with an agent helping us. Food was almost non-existent. Pre-flight went well once I got the app reloaded on my phone since we don’t fly much anymore.

I like that it got us where we were going. Everything else needed work. It was 1/2 hour late and we took off an hour late. The plane had to be cleaned and the disabled loaded on board before we could take off which took forever and then we sat at the terminal FOREVER before we took off. The ride was so bumpy that they couldn’t serve drinks and snack but to about 1/2 the plane. Seriously we should have flown out of Fort Lauderdale. We probably would’ve gotten home several hours earlier.

Flight was on time, the staff was personable & professional, & the plane arrived on time.

Flight was great. DELTA did a fantastic job! FLL airport was chaotic!

You lost my luggage!!! How frustrating!!! Now they can’t find one of our bags!!!! I really don’t have time for this!!!

Business class is great. New airplane, very comfortable, better than some of the major airlines I am used to

great flight. Pilot was communicative, flight attendants were excellent. Really nice experience except my tv didn’t work.

Overall, the flight was better than the flight I took to go to Florida, which had a bunch of problems. The crew is really nice and the plane was new so it had a small problem when we were on the runway, but the flight itself was great. They even made some time back up, which is always a good thing.

Everything was good except for deplaning in NY. Took way too long!!

Jet Blue keeps getting iit wrong. 4 hour mechanical delay followed by terrible boarding experience. This is my third horrific jet blue flight in 2024. I am going to try to avoid this loser in the sky

Delayed by almost an hour - I also noticed that all JetBlue flights departing from PBI were delayed yet the weather was perfect.

My experience with JetBlue was fantastic! The service was top-notch, the flight was smooth, and the staff were friendly and helpful. I would definitely fly with them again.

The free wi-fi was great. But, the flight delay was not sustainable. It definitely impacted people schedules and JetBlue didn’t do anything to compensate clients for it

I loved the wifi, much better than Delta. Seats were old. and bathrooms dingy.

no wifi and the aircraft was very old with tiny 4” screens.

That flight was smooth, and staff we courteous. it was a full flight so very tight. The boarding through security was not properly controlled. it was rushed and the scanning process for our bags, etc. was pilling up at the other end with no time to empty our belonging my personal items almost toppled over on the floor if i hadn't caught it rapidly. Was it just that time, or always like this - cant say. other than that all else was fine.

Boarding was friendly and quick. While the plane model was older with no live tv, the entertainment was full of movies and tv shows. All food was available. Pilots were very communicative with status of the flight. Flight landed on time.

It was terrible because the flight was delayed for 3 hours.

Crowded flight, but upbeat and kind crew. Pilot greeted us at door, flight attendant thanked a number of “special” passengers for their business, another addressed an eight-year old boy as “young man.” United obviously trying to up their game, but though all of that is nice and notable, flying still feels like moving along a human assembly line, being herded into one small space after another (boarding areas with too few seats, planes with limited personal space, shuttles (IAD) packed too full.

Did not like the seat spacing. The seat was very narrow and tight.

United domestic flight was better than international flight. There was no switch to control Ac In international united flight. Food was also average, Air canada food was much better than united.

Seat didn't recline all the way back. Very uncomfortable flight for 8 hours. The turbulence eliminated snack and food stops

Nothing exceptional but all good. Business class seats are like the domestic Mint class on Jet Blue. Comfortable but not exceptional. Food is good but not superb. Flight attendants were better than US carriers but that is to be expected. However, not the caliber of Asian or Middle Eastern airlines. Very Lufthansa like but Lufthansa has slightly better seats, even though they are hardly best in class

The flight was clean and on time, the crew were all very nice and we got the seats we booked. Plenty of food and beverages. The seats are too close so it’s very difficult to try and sleep comfortably.

Any flight that gets from point A to B with no drama is excellent.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

Horrible people at the gate, they force me to check in my carry on, even thought no one behind me has to do it. I had to get out of the airport in NY to get my bag and go thru security again on my way to Honk Kong. The worst part is the employee threatened me with loosing the flights if don’t comply.

Horrible. Flight was delayed and very bumpy. I was super unhappy

The agents at the gate were rude. The stwards were pleasant. The seats were comfortable. The tray table had crumbs on it. A passenger talked constantlt and very loudly for the entire flight annoying many passengers. The stewards did not ask her to speak in a lower voice but my travel partner did.

Literally the worst experience ever and I had my service dog with me. Flight was supposed to leave at 1:51 PM but the plane arrived late. They boarded us around 3 PM and kept us on the plane for an hour saying that due to weather conditions in Miami, we could not takeoff yet. After waiting for an hour, they deplaned. And then they will not give us our bags back that we could just leave and schedule for another flight. Every hour they kept updating saying we have to wait another hour without any explanation as to what was going on. Eventually, I went to customer service to change my ticket, but by the time I made it to the front of the line, they started boarding my flight again. And then when we got onto the flight, they said there were two flight attendants That were past their shift. They kept us on the plane for about another 40 minutes until they told us they had no other flight attendance and had to deplane again. Then I gave us hotel vouchers and told us we would be on a flight at 6 AM the next day. At this point it is about 9 PM. I get to the hotel with my dog, who hasn’t been able to go potty for about eight hours. When I arrived at the hotel, I got a text alert saying my flight has been canceled at 6 AM and they moved past to 5 AM, however the hotel shuttle doesn’t leave early enough to make it to the airport for 5 AM flight. So me and some other passengers got a cab after about three hours of sleep to get back to the airport. This was the worst experience ever.

One of the worst flights I have ever taken Delayed over an hour without communication from the crew; very scary Entertainment not working Crew NASTY cabin cold

May never fly American again Delay in take off WITHOUT EXPLANATION Cabin freezing Crew NASTY entertainment did not work entire flight

Plane felt so crowded and tightly packed. The chair itself was not comfortable.

Flight was delayed due to crew not being there, besides that it was a normal flight.

We were re routed due to a flight cancellation. We did not fly out of Miami. We originally booked first class and were moved to coach without being compensated.

Flight kept delayed from morning to late afternoon so I had to make other arrangements

The crew was not great or professional. It seemed like they didn't really want to be there. A true lack of effort for accommodating customers.

I paid for WiFi, but it (WiFi) was very very slow, will never take again! Impossible open Utube 😤😤😤

My wife and I are both handicapped and at boarding they upgraded us to a seat closer to the front rather than all the way towards the back. Much appreciated.

Spirit canceled the flight in March and never notified me!

Seats suck, not enough room, overcrowded planes, hectic situation all together.

I do not like the customer service, I had an emergency and needed to cancel a pet reservation right after I had booked it and they would not do anything but issue a credit. I haven't flown in years as I have 7 kids and don't have spare time. I want my $125 back on my card please

I paid just under 200 for flight and luggage, then paid 200 to change the flight, then paid 100 for a carry on. Then the cancelled the flight. Of the 500 I spent they refunded 250. I bought a delta flight for 270 never flew with spirit, but spirit kept 250, not even refunding the 100 for the carry on though they cancelled the flight (for weather on a day with only a slight rain ).

Flight attendants heavily pushed their affinity credit card. Very annoying

On time and fast. Overall it was a pleasant experience.
