It was a crowded flight. They did the best they could.

6.0 GoodNetty, Apr 2024SYR - JFK

It was a crowded flight. They did the best they could.

Boarding was great. The flight landed early. It took the crew over an hour and a half to bring out drinks. I paid to upgrade my seat to Comfort+ only to be near a crying/screaming baby who was seldom quiet. Noise-cancelling earbuds didn’t even help. Waste of money to upgrade.

Boarding was a sh!t show. JFK BOARDING was awful. The agent called three sections at a time Clogging the area then yelling at people to not block the walk way. How are you going to call delta one , premium select and comfort plus at once and the yell at highest paying passengers. Need to do a lot better and the flight attendants in the galley need to understand that their voices travel. They were talking about others and everyone in the cabin heard them

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.

Horrible. First delta flight was delayed. I ran to my connecting flight and arrived to the gate 13 mins before departure. I told the gate agent “I’m here”, she told me flight was closed while giving my already confirmed seat to an stand by passenger. I said again “madam, I’m here with my confirmed seat” and she said “no you’re not here@ and gave two stand by people a boarding pass and let them board. I asked “madam, why do you do that?”, and she repeated “you’re not here”. That was very rude. I’m disappointed of delta. It used to have a good customer service. Things have changed, but not for good.

full flihgt but crew and passengers all helped eachother we landed early! however we then had to wait 40 minutes on the tarmac to get into the gate there were people trying get connecting flights, assume its an airport issue but still frustrating

Bad crew with full of attitude, bad plane. Pls get some new planes. No food, no drinks nothing

The crew was horrible. Cleo was the most unwelcoming flight attendant I’ve ever had.

Do not get fooled by the term “Delta One” flat bed! The seats were super narrow. The ottoman for the feet was so narrow that when you recline the seat in flat bed position, you can only fit one foot in the 8” width space. There was only 1 flight attendant for First Class. The breakfast took 2 hours to get served. Instead of offering French Toast, the served bread pudding. The champagne with orange juice or Mimosa tasted terrible. Almost all the movies offered were ridiculously old. For a long flight from San Francisco to NY, it was frustrating! I DO NOT RECOMMEND this flight!!!

Really big guy next to me Attendants moved him to an open row

We waited to takeoff for about 1 hour delay for a 20 min flight.

Packed in like sardines, very uncomfortable. Sitting the aisle my shoulder was rammed into numerous times by rushing flight attendants. Also flight was very cold.

Your app is impossible to use. I couldn't load it. Then i couldn't open it. When i finally got both those things done -with much help -then i couldn't open the app to install a credit card. The upshot was 4 flights without access to food or drink. When i first tried to download united app some company called starlier opened instead and i would up signing up for some 49 dollar a month music service which i still have not been able to cancel.

Overall it was good. The flight was bumpy at times, but the pilot made us aware every time. As a result, no snacks/drinks were made available. Seats were tight but that’s okay as I had a window seat.

the head jack on my seat didn't work and the power outlet didn't work for my seat

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.

I liked that we arrived earlier, you could improve your snacks give away

We learned certain countries (a few) require a notarized letter from an ex to give permission for children to travel to those countries with the other spouse together with birth certificates. To find this out one hour before flying—not good. Nowhere is it documented by the airlines though they require it. Make sure about all documentation required.

The best part was we weren’t too delayed. Seating space in economy is insulting and about as uncomfortable as one could expect before mutiny breaks out. Prep for landing happened well over 45 minutes before wheels down: no final garbage pickup and it interrupted those of us who needed tray tables down for dinner, etc.

My luggage didn't make my transfer in Newark. It took 4 days to receive it even though I tried to pick it up at the airpory

Comfort of seats, ease of boarding. Food selection could be better

I arrived to the airport 2 hours before my American Airlines flight was scheduled to take off. I have TSA pre-check. The airport was crazy packed when I arrived. After momentarily standing in the pre-check line, the TSA agent said that I am not pre-check. Of course I said that I am because I entered my KTN number on all my traveling sites and programs. I had to get out of line and go back to the AA counter to discover that American Airlines did not add my KTN to my boarding pass. I had to call TSA to find out my number, then have AA enter it onto my boarding pass. The emblem would not load onto my boarding pass. By this time, I decided to use my Clear in order to get through TSA but the line was ridiculous long. By the time I made through TSA, I missed my 11:08am flight and was re-booked for the 5:30pm. This is after the AA employee told me I should have gotten to the airport early. AA use to be a dependable airline not I use them only if I have too.

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.

Cut off carry ons, had to check, got on and there was plenty of bin space. Disappointing.

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

The flight was so short that the lack of leg room didn't bother me for long. The plane was smaller so only two seats per row and there were chargers. However, they didn't serve any snacks.

They needed to de-ice the plane. Apparently airlines have a problem keeping their de-icing vehicles in good repair. After we backed away from the gate we sat and didn't move for nearly an hour. Nearly an HOUR with minimal communication from the flight crew. Eventually the sun took care of what American Airlines could not and melted the minimal ice. We finally took of a hour late which, in turn, jacked up our connection in Chicago.

Horrible trip. I won't fly AA again Boarding was a nightmare because they squeezed people into the waiting like sardines. My connection was 30 minutes and the run to the gate was horrible. Then the flight was canceled AFTER boarding. The Flight attendants did not know what to do and gave out the wrong instructions. They finally sent us to a different gate. Again, the waiting was like a sardine tin. The flight was okay and my baggage arrived fine.

American Airlines gets worse every time I fly them. This is the 3rd time they lost my bags in a year. I also think their employees do not care when I communicate that I’m unsatisfied with the airlines. I’m a credit card holder, fly first class, and an advantage member but I think that I’m finally going to make the switch to Delta.

I had no legroom, although I paid for extra legroom. I could barely put my bag in front of my feet and under the seat. The Wi-Fi was horrible. In fact the flight attendant said that they had to reboot it and see if it was going to work and never did.

Overall it was a miserable experience... I will never fly spirit for more than a 3 hour flight or overnight.

Flight attendants heavily pushed their affinity credit card. Very annoying

Very bad, delayed flight. I was offered 2 vouchers for inconvenience, but those vouchers aren’t usable. Spirit airlines is betraying people.

They didn’t let me get my boarding pass through the app because I have a lap infant. The ticket said to see a gate agent but there was no gate agent available. I was supposed to go to the kiosk. Ended up missing my flight and they said that I never checked in to my flight so there was nothing that could be done. I will never fly spirit again. Not even worth the hassle and poor customer service.

I like the price. I did not like the seats: very little space and not reclining.

I like strict carry on policy. Quick to board, quick to leave. Less time at gate and get there quicker

comfortable flight. not fond of the idea to pay for every little detail. baggage checkin or carry ons, basic snack, or some sort of basic entertainment/wifi. would be nice to offer these as perks and stop with the penny pinching.

The seats were larger & more roomy than the old planes. the crew was excellent. . overall a very good flight.

First flight delayed and spirit didn’t let me on my connecting flight even though I made it on time because they overbooked and gave away my seat.
