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.

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.

Very well organized both boarding and deplaning. Very satisfied with the service I received.

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.

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

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

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.

Crew professional. Easy bag drop off. On time. Good entertainment.

Flight was late and missed connecting flight. They could have better accommodated, but instead did an overnight and had to arrive the next afternoon.

The boarding crew was incredibly helpful getting me on an earlier flight

They have lost any customer service care and support. Terrible airline now and been for awhile.

The flight was delayed leaving Miami. When we arrived in Charlotte, we were unable to park at our scheduled gate. We had to wait another 30-45 minutes before we could park at a different gate. All in all, we were delayed by almost two hours arriving in Charlotte.

The flight and boarding process was smooth. Wifi was unavailable and I prepaid for it. Have requested a refund

Spirit is a very uncomfortable travel experience. It’s cheap but you are squeezed into the seats like canned meat.

Friendly employees, good seat, on time, Great flight. Pilot and attendants greeted passengers as we deplaned. However, I could not ever understand what the flight attendant was saying on the mic. It was too fast, and too loud.

The flight was delayed four and half hours for paperwork on a maintenance issue. Very frustrating.

Flight was on time and was not crowded. Flight attendants were very understanding of my wife’s back problems.

Seats too hard, too much lumbar. Space between rows was extremely tight, so tight hard to place item under seat in front of me. No tv screens. Zero plugs for charging phones. Too many sales pitches

It was a short fight and even though we had a delay due to weather we arrived on time

The flight was canceled and was bounced around time wise with my elderly parents. That being said the gentleman in custody service was amazingly helpful

It amaze me how other airlines leave on time and Spirit always have some type of delay. I’ve flown with Spirit many times, but it reached a point I’d rather pay twice the amount and not deal with this corporation they never do nothing to reimburse people for their time or headaches.

Easy boarding and good flight. Need to work on the beverage and snack situation
