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

5-hour delay due to storms in Tanoa and airspace restricted by Miami traffic controllers.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Horrible. This was not first class. This was a connecting flight whi h was late. My original flight never came. I hated the fact that delta gave me a connecting flight from New York to Orlando Florida. No meals and the television screens were not working. There wasn't even any power to charge your phones. This is NOT FIRST CLASS DELTA!!! Do better next time!

They did a fine job. Can't wait to use Delta in the future.

Seat back monitors and outlets were dead and not working.

The experience was good and the flight departed on time and landed early

The flight was delayed but we got to our final destination.

public website still broken for years randomly blocking browsers with privacy options active after loading a page maybe once. check-in on laptop was almost impossible but eventually randomly worked. had to print pass at airport since couldn't get back in to load digital pass on mobile firefox or chrome. red eye flight so smooth onboarding, plenty of room to spread out, easy offboarding. onboard wifi instructions mention vpn can cause problems connecting but fails to also mention private dns. no printed or built in menu list, seems weird to require personal device to point at qr code link for menu which does not even allow direct ordering. people with health condition risk related dietary restrictions trying to avoid for example cholesterol and sugar are left guessing what they can order either way without nutritional info highlights (cranberry juice was minute maid cocktail with as much suger as typical can of soda). tap to pay wasn't working and always seems sketchy to manually enter card info. good movie variety, so limited tv was okay.

Boarding super slow with people allowed to linger in aisles

They put me on a chair in between two men, one overweight who was almost falling on top of me, and the other was even uncomfortable because I was half falling because of what the other was pushing me. I stayed with. my feet were swollen from fluid retention and from being unable to accommodate myself. it was very uncomfortable. I asked for help but they told me that the flight was full and they couldn't help me. I got off the plane almost unable to walk due to the inflammation. and then at FLL airport I asked for help because I couldn't go to my next flight, which was a connection.

Run out of snack choices. Why are the seats not padded for your butt? Are we sitting on blocks of wood or metal for $250-300 a pop? This ain’t spirit. Let’s get it together people

Safe and on time were the positives. The plane wasn't cleaned before boarding, there was garbage and food on the floor and in the seat pocket. The TV screen was small and the picture fuzzy, audio quality was poor. Seatbelt was fraying and seat did not recline properly. No charging ports near the seats,

Terrible. Flight was cancelled due to the weather in the east and sout east(florida). Did not get any compesation of any kind. According to them, it was not under their control so I lost all the money paid for the 2 fairs from Raleigh, NC to Orlando, Fl.

There were multiple delays but JetBlue tried to make the boarding and departure process as quick and efficient as possible. The crew was as detached from reality as could be, meaning: not very friendly and just doing things by the numbers.

40 minute delay before take off after boarding flight. Bright lights throughout night flight due Issues with light panels. In flight Entertainment nonfunctional

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.

I hate their constant delays! It’s as if I cannot confidently make plans for timing when I'm traveling with them. I slept through it, so all I can say is it was good.

Did not wait long for wheelchair and attendant to arrive after checking in. Wheeled down to plane Was greeted with a smile when entering the plane Choice of snacks was very limited to 2 items. Seats are uncomfortable. My butt was sore after the 1st hour of flying. Needs better cushioning at seats.

Did not wait long for wheelchair and attendant to arrive after checking in. Wheeled down to plane Was greeted with a smile when entering the plane Choice of snacks was very limited to 2 items.

Everything was fine once we actually got on our flight. It was more then annoying they canceled (delayed) our flight. We lost out on a day of our trip along with money on our stay. Plus we had to book another hotel. So expensive.

This flight was canceled and delayed several times without explanation. The plane was freezing cold and no wifi for messaging. Getting off the plane was terribly unorganized and felt like it took forever….

Use planes with TVs on flights over 4 hours. The free entertainment was a cheap in between solution for a very long flight that you don't even bother providing meals or decent snacks.

Flight was cancelled had to move to another gate late again no internet paid for the month and never can use it waste of money

Flight delayed over an over all day until it cancelled at 1:30am. Would not repeatedly delay that late. Offer hotel rooms and rebook early. Very difficult for families with small children

It was a good flight. Of course it was full, but it went well.

We sat on the plane for 1 hour because the airline was short handed could not be unloading.

We sat on runway for an 1 hour because they were short handed at key west airport was not fun

We are gluten free, there were not any available complimentary gluten free options.

Flight delayed 3 times. We were directed to go to a gate across from our gate. The plane wasn't there yet so we had to wait for it to arrive, then deplane everyone and then wait again for the plane to be cleaned. After 45 minuites we were allowed on the plane. The first plane had mechanical issues. The 2nd plane must have had bathroom issues because we did not have any food service whatsoever. No snack or beverage. That made for a long time not to have anything considering that we had just made it to the original gate and we had no time to stop to get food or a drink. Then we didn't want to leave the gate to get food because we wouldn't know how much longer the delay would be. Then the next gate change. Had we been told that the total time would have been aprox 45 min later we would have left to get food and a beverage. We had to wait again for the okay to the pilot to take off so we were on the runway for another 20 min. Overall, we were delayed over 2 hours which felt like 4 hours.

Two delays in less than 24hrs. They need to improve everything and restructure the whole company.

Not enough help at airport during boarding process. Flight was delayed. Overall WORST flying experience I’ve ever had. Will NEVER FLT SPIRIT AGAIN

The non stop flight and able to go into Atlantic City airport. They could lower the prices. It starts out low but then if you want to bring luggage and pick your seat the price goes up quite a bit.

Flight expected to leave at 6:40 pm ended leaving at 8:00 am the following day. I slept in a cold airport. Never again Spirit for me…

My flight was cancelled!!! I had to spend 200.00 on another flight!!

Horrible. Delays, no customer support and fake promises and everything. i am suffering to help as due to connecting flight getting missed no support on ground and customer support window is closed and we are sitting o ground without anything

Absolutely terrible. The boarding process had zero organization. Mobs of people trying to board. People were climbing over my child's stroller with her in it. No families were boarded first. Boarding was delayed with no reasoning or notification that it would be late. We were then stuck on the plane for 45 minutes after landing. Then waited over two hours for our luggage. There was zero communication with the travelers. Never have I experienced such I professionalism and disgrace of others. Extremely disappointed.

Terrible… missed our flight due to ridiculously long time to go thru baggage check-in!

Everything was really good but the seats are not very comfortable.

Spirit canceled the flight in March and never notified me!

My flight was cancelled from Gainesville. I was able to get on another flight on Friday. Will see if this one cancels also?

the hospitality was excellent to me and I will return flying with them

I am very disappointed. I booked with kiwi when I got to the airport there was no reservation I had to purchase another ticket after my card was already charged for almost double the cost I payed through kiwi eight days after I went to their office in Tortola and they refuse to give me a receipt so that I can cancel the original payment. They said “ there is no record that you used silver to travel “ I know I did not swim to Puerto Rico . If someone can help me please so that I can cancel the payment the credit card company said I need it, I have less than 14 days or I will loose my money. This is terrible and there is no local number for them.

I booked because of time of the flights. I needed to be at my destination at a specific time, and missed my appointment because of your delays.Get rid of these junk planes. The ATR planes are dated old scary planes. And maybe you could actually be on time. This airlines on time record is horrible. The communications between the gate agents and this company dont exist.. They couldn't give any answers,. When trying to find out when the flight would leave, they get no response when they asked for details on flights, they receivedconflicting information. I felt bad for the gate agents having to deal with Silver's inability to communicate simple information. This is my last choice in air travel. On time flights are everywhere, and both flights I took were delayed. It's a sad company.

The flight itself was good and the flight attendant was very good.

It was awesome until we ran into some bad weather but the pilots did an amazing job getting us to safety and landed

If you take this airline, they WILL change the flight time, and make you miss your connection. It has happened every time I used it. It's so unreliable that I think it shouldn't be offered on Kayak. You will regret it!

In addition to the fact that Silver changed the flight time several days before the trip without offering any choices , I was sick with Covid and unable to go on the trip. I tried to ask Silver for a credit for a flight when I’d recooperated but they don’t do credits, even for illness. I will Never fly on Silver again

I canceled due to a 7 hour delay. Was forced to book another airline last minute , very expensive. Silver Aorways sucks

I spent hours with orbitz to get my tsa # on my ticket. They didn’t have a place to enter. I will never use orbitz again. No customer service. A number in which u press offered options and the message replays instead of getting customer to that area. Silver did not make the promised call back. Finally someone responded to my email and took care of it after I lost hours of my vacation arranging this. Staff on flight barked orders.
