It was Delta, but the flight attendants were stressful and disrespectful. I am a diamond member a travel weekly. I have not had a negative thing to share in quite some time. But this was noticeable.

It was Delta, but the flight attendants were stressful and disrespectful. I am a diamond member a travel weekly. I have not had a negative thing to share in quite some time. But this was noticeable.

Comfort Plus seat 11E seemed smaller than prior flights. The movie selection is good. Watched most of the most recent Tron movie. I'll watch the remaining part later as my movie is saved in the Delta Seatback Experience.

Flight was late from Newark to Atlanta, I asked flight attendant to please let my family of 3 out first when we landed to Atlanta because we were late for our connecting flight to Quito. She didn't and we were late for 5 minutes we couldn't board the plane and spend hours trying to get another flight with customer service for the next day.

I really liked the legroom. I am 6’4”.a at For some reason our seats were not together and using the app to fix it didn’t work. Passengers were nice enough to move for us but you should absolutely ensure a parent sits with their child.

Late delayed flight delays boarding and delays leaving and delays on arrival too. Cramped plane no room no food.

DTW line is too long. The flights from DTW to BWI are always delayed for unknown reasons.

Delta canceled our flight and we had to scramble to find another airline to get home. Phoenix is not a delta hub so they didn’t have another plane. It would have been a red eye though Salt Lake City. Getting in at 5am. No bueno.

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

This flight was a first class choice and left much to be desired. Seat backs on seats were falling apart and torn. Seats actually didn't come to a "full & upright position". Pull out table was sprung. Not any significant leg room. All in all we were on an obviously older plane and felt overcharged for what we received as first class.

A 12 hour flight during the day with one real meal service - are you kidding? Also the breakfast was one of the worst and not what was listed

Lower WiFi prices; allow us to see our flight on a map; more variety of drink choices.

So excited very proud first of all I wanna thank kayak all updates very professional and fast alart And amazing cabin crew so nice to me they deserve big salute

UGH I HAD TO MISS MY FIRST FLIGHT TO TAMPA CAUSE OF THE 10 MINUTE DELAY OF THE ORLANDO TO MIAMI ONE SO THEY HAD ME GET ANOTHER TICKET. I AM NOT HAPPY AT ALL BECAUSE IT MADE ME MISS MY CONNECTING FLIGHT FROM TAMPA TO LONDON AND FORCED ME TO MISS A DAY AT MY ROOM IN THE UK.

Wish they didnt delay off-boarding for 10 minutes so i could connect to my flight from miami to tampa

We experienced gate changes and a long delay. My seat was dirty when I boarded and I had to use wipes to clean it myself. There was an unpleasant and overpowering cleaning product scent on the plane as well that lingered through the flight.

Seats were much more cramped then on the 737. Narrower and rows closer together. Flight was absolutely packed and the plugs under the seats didn't work. Was forced to check my bag even though previous flight had no issue with it.

Good food & refreshment. The seats and entrainment screens are modern compared to others. The staff though pleasant serve and attend to passengers based on nationality. Some get served first others last regardless of their seating positions.

It was fine. My connection in Charlotte to go to WPB was too late and I had to spend the night in the Charlotte Airport in the mini suites.

The flight was on time and arrived early. The crew were friendly and helpful.

My carry on baggage was damaged. Entire trip, I had to carry the baggage. When complained to the boarding crew, they got mad at me and still asked me to valet check in the cabin baggage. Rude boarding crew!!!

I've flown two Spirit flights recently - boarding for one was somewhat chaotic, with the board listing the wrong flight and causing much confusion; boarding for the other was very smooth and easy. My seat (for which I did not pay extra) was a bit narrow and without great legroom, but it was fine for a NY-Florida trip and was more than worth the low price I paid. The crew was friendly and one flight landed early and the other was only very slightly delayed. All in all a very good experience.

Had to pay for water if wanted it. Seats are close unless you get upgraded. Flight was fine. Will travel again with spirit.

Good! But your flight crews don’t need to ‘eat the mics’ when making announcements. If they held the mics 3 to 4 inches away from their mouths, we could understand them so much better. Otherwise, all is well.

Your flight crew and boarding area crew need to have microphone use training. They all hold the microphone right up to their mouths, way to close making understanding them almost impossible. The microphone should be held about 3 to 4 inches away from their mouths. This would provide for much better clarity through the PA system. ‘Eating the mic’ DOES NOT work.

It was the first time I flew on that airline and had a very positive experience. Nearly identical to Jetblue which consider the standard of airlines excellence.

A bottled or canned drink, whether water or soda would have been appreciated upon settling in and flying, without being charged for it.

Horrible experience. First and last time using this airline. Made an announcement that boarding will start in 15 minutes, canceled the flight 5 minutes later due to no airline staff. Had to book another flight on Delta since Spirit had no other flights arriving to my original destination the same day. I wouldn't recommend anyone to fly with Spirit. No wonder why it consistently ranks high among worst airlines.

Once again, the staff seem to think they are above the customers and treat everyone with disdain, belittling people.

Sadly there was a crew member very rude with my kid and with me.

COMMUNICATION!!!! The issue was a crew shortage, which means you knew in advance the issue. Instead of notifying people in advance, we're finding out an hour before the flight it's canceled. You rebooked people to more flights you knew wouldn't get out. You ended by taking part of my party to a completely different state and leaving them there. The next morning, you still have no way to get them to the original destination and they ended up missing an important event. We came out of so much money to check bags multiple times. And on top of all that, the staff in the building seemed to not care and were fairly rude. Overall, just go on and fold and quit making promises to people to get them places when you know you can't. Shoutout to Delta for doing a great job at making it less painful (for those of us who made it).
