We love flying Newark to Fort Lauderdale, and the time slots of Spirit Airlines are perfect for us. We certainly hope that Spirit doesn't stop flying under Chapter 11, but that is certainly a risk we need to consider if we are buying tickets months in advance. Also, it only really pays to fly Spirit if you are flying light - check for allowable size and weight of "personal items" that are exempt from add-on fees.

Be ready for the unexpected expectations at the gate if they can’t confirm your id bc you will be required to go to the check in desk. This is specifically for online purchases where you will initially skip the check in desk. Most times, you can go back to the priority line upon return.

Fly directly into Miami if that is your final destination. Ground transportation between FLL and MIA is expensive ($50) and time consuming (1+ hour). One would think there would at least be hourly public transit between the two airports, but no such luck in the late afternoon. Choices are $50 bus ride or $50 ride share, or $50 bright line, or $50+ rental car. No afternoon Tri-Rail service. I chose the ride share since it got me directly to my downtown Miami hotel.

No in flight service, no explanation - FC got service, C+ did not, unsure about Economy. No turbulence to speak of, so I guess another way to cut cost, or promote health and well being of Delta employees? Also, boarding in MEM combined zones, and with overhead space already full on both flights after Zone 2/ Diamond, presents a huge challenge to find a space for a bag. Delta, other than point A to B, is no longer reasonable to fly - very poor experiences, not even taking into account the chastising at the gate and rude crews, across the board.

It would have been better if the flight wasn't delayed by 2.5 hours

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.

Delta is a good airline. I've never had an issue with Delta. I'll continue to fly with them until they show me that I shouldn't.

Flight was operated by Virgin Atlantic and it was up to their usual high standard. Minor grips about some issues, but they are really first world issues and as a whole, was an excellent flight.

Original flight was cancelled and when i was rebooked by the airline, they couldn't seat me in the same type of seat as I had originally booked (went from window/aisle to middle/middle and one was a bulkhead seat, and other wasn't in the same class)

First, Delta needs more flights to/from Miami. Second, a 1000pm leaving at 1230pm is unacceptable from their biggest airport world hub. Another aircraft could have been used such as the aircraft scheduled to be used in the morning for that exact same route. Yes, I did get me there but the lack of sleep the next day didn't help me enjoy my entire trip since I was busy with activities during the weekend. This can be and is expected from Spirit (going bankrupt) and Frontier (despite they're nickel and dimers). But from Delta's World Hub? That's totally unacceptable!

Service in business class was not impressive. I ordered coffee with dinner and then watched other people get 2 refills before I got my 1 cup of coffee, and only after I pressed the attendant button overhead. Furthermore, the seats in the forward cabin need maintenance on this 737-800: the upholstery is detaching from the seat frame, at least on the backs of seats 1C, 1D.

I truly love flying with Delta. They have always treated me with the upmost respect

Our flight attendant in FIRST CLASS was one of the worst I’ve ever had. She was not at all pleasant, nor particularly good at her service.

Delayed, toilets did not flush, pilot parked to far away from Gate

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

Miserable. They moved my seat, but canceled the next leg of my flight. I resolved the issue at my transfer, but that resulted in lost luggage that has taken days off my schedule with no resolution. Worse, they fail to interface effectively with Lufthansa, forcing me to bounce between two equally useless help desks. The apps are unable to handle the situation, the bag dropped off the tracker, and while the call centers are polite, they do not provide written information to assist with cross-airline communication.

left on time, reasonable boarding process arrived early luggage came out quickly

I like flying first class, and United has a nice one

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

Check-in, boarding and the flight from Phoenix to Houston was quick and easy. The flight from Houston to Shreveport was delayed 5 hours. It was frustrating but I think United handled it the best they could.

They lost my luggage, so, not happy. The crew was nice but my suitcases never made it, still trying to find out what happened!

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

On the plus side, crew was attentive, drinks were cold, and in-flight entertainment selection was better than some other airlines. On the negative aide, Plane was delayed almost an hour, either no announcements from the gate crew. Biscoff cookies are gross, appreciate airlines that give a choice. Also, crew had no personality or enthusiasm at all.

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.

I got sick nothing contagious but distressing and the care I received by Kayla? Keighly the flight attendant will be memorable for ever. Thank You

Waaay too small plane. They also need to up the size of the overhead bins. I would love to keep me 3k with of camera equipment in my hard case baggahe instead of it being thrown into the belly of the plane

Attendants were pleasant and the flight was smooth and relaxed.

It was fine. No drinks nor snacks offered though. I thought that was unusual.

Delays to take off and to leave the plane after landing added a lot of time to this flight.

It was a red eye flight, so no meals were provided, but it was fine with snacks. The seats felt cramped and almost too narrow.

Horribly rude check in at airport, worst in 25 years of flying. All over a simple issue they could have googled to resolve.

First time flying with JetBlue and never again. I went to the counter to request meet and assist because I'm 74 and my wife is 79. I walk with a cane and my wife is handicapped and has her own wheel chair. I told the agent that my wife and luggage was at the entrance door. The ticketing agent said to me that they don't offer meet and assist. I need to bring them our luggage and then go back and get my wife in order to get my boarding pass. As I went back to get my luggage a Southwest agent along with a TSA agent recognized the situation and came over and took my wife and luggage to the JetBlue ticketing counter alongside the line and told the JetBlue agent to issue to take our luggage as soon as they could.

Our flight was delayed 5 hours, very disorganized, bad communication, confusion. Only good thing was the crew.

1) No pilot available for 1 hour 2) no room for most passengers careyon in overhead—-> stowed below 3) when we landed we had to wait 45 min. Before docking at gate as gate was not ready

It was good. I prefer JB over other airlines.I just wish we had headphones for the films, but other than that - good.

The ride share experience in JFK is terrible. After traveling on a flight, then you need to take a subway to the last stop to get an uber or lyft. Unacceptable. Bad job JetBlue for permitting JFK and Port Authority to do this to your passengers.

The flight was two hours late due to a computer fault and resulting maintenance. Nothing was offered as compensation beyond bottles of water during the time we were deplaned and waiting in the terminal.

Very pleasant flight attendants. Gate crew rather loud chatting with each other.

Four plus hour flight delay in New York caused us to take off after 11:30pm. We didn’t arrive at our hotel until five hours after check in. Started the trip off feeling exhausted.

Plane was in bad shape. TV’s and WiFi didn’t work. Plane need a refresh. Not enough room for bags.

Cheap, only one short delay. No issues despite bad weather. Able to take a big backpack for free.

I know Spirit gets a lot of criticism, but I've taken three flights recently and all were very good, and tremendous value. On my most recent one, they randomly assigned me to a very comfortable exit row seat! The flight was on time and the boarding process was smooth, and the crew was friendly. No complaints!

My experience with spirit was horrible I had to spend a extra $100 to check in my bag when I already purchased my ticket even when I got to my gate to get my seat the attendant didnt say anything until I was boarding the plane..also to make matters worst I been flying from Florida to New york and Florida to Atlanta often this was my 4th trip to Atlanta with the same bag and never had this problem till yesterday so im extremely upset and I wasnt even giving a reason for the change the attendant just gave a attitude and wouldn't answer me at all

Paid for wifi the day before but wifi was unavailable on flight.

Second time in 3 days I walked off the plane late. This time - almost an hour.

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.

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.

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).
