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.

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 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.

Flight was delayed several times. At one point, they "pulled back" 15 minutes from the delayed boarding and sent a text saying we would board sooner than previously advised. The flight then was delayed again. And when we boarded, there was an unspecified technical issue which had us waiting in the plane for about an hour.

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.

The flight was delayed by two de-icings. The seatbelt did not work correctly. It did not stay tight.

Everything was absolutely wonderful from check in to baggage claim. Staff was very professional and sweet. Will definitely recommend United to family and friends.

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

Hotter than Hades in August. Why, why do crews think that in the winter when we are already dressed for cold weather we need a cabin that is 82 degrees. Even the vents were blowing hot air.

Unbelievably poor service from flight attendants. They didn’t even do water service on a four hour flight. Just disrespectful.

United is an incompetent airline. They parked the plane on the tarmac for an hour after arriving because they “didn’t have a gate available” it was actually some sort of lie because as we de planed there were approximately 9 open and manned and empty gates that we walked past. Many people on the flight missed connections for the hour long sit on the tarmac. Utterly baffling and incompetent behavior from United flight ops.

Flight was delayed. De-icing took a while. When we landed had to wait for another plane to vacate our gate. Just an overall bad experience.

I understand weather is an issue, but making us chase our plane down at five scheduled gates across three terminals in an airport the size of O'Hare was unfair. They'd have probably been better off to leave gates as TBD until the inbound plane is in final approach instead of running us all over the place. Also, props to the consistently-unprepared ground crew in Richmond for once again leaving my lane parked short of the gate because they couldn't have a crew in place on time with 2 hours notice...

I boarded flight UA#1318 at Sacramento International Airport going back to Houston TX. The flight was scheduled at 5:10am. I was able to check in virtually using the United Airlines app. When I entered the airport, there was no one outside assisting with checked bags as it was for Delta Airlines. Immediately upon entering, there was a LONG, EXTREMELY LONG line to the kiosks to get boarding passes. I stand in line to get boarding passes then had to move to ANOTHER EXTREMELY LONG line to get my bags checked in. While standing in this line, we noticed an agent taking customers to 3 at a time to her station to check their bags in. Lucky for me, she called me back, checked my bags for me and I was on my way. I then encountered another long line at the TSA check and to avoid I ending up having to sign up for CLEAR to bypass it. So glad, I did.,...Both of my flights were great with no issues, butthe check in progress at Bush Airport was so much smoother. Check-in at SMF airport needs to be anaylzed and corrected. Do better United, I know you can....thanks

cabin crew was OK, food was OK, the trip from the US to Munich was actually pretty bad comfort wise. Noisy aircraft, lights never dimmed even in Business class (night flight) barely sufficient amenities for the price. I have millions of miles with United but TBH American is gaining ground and Delta has always been marginally better then United although on paper United has more longes and cheaper upgrades.

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.

We didn't take off until an hour after we boarded.

Wish they had the seat-back video screens for watching movies or playing games.

Very good but wish they had the seat-back video screens for movies & games

Flight was delayed not sure why no explanation given and no apologies either. Otherwise the flight was fine

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.

Everything was great. I liked the text updates so that I never miss a gate change & I have all the latest info.

I don’t usually fly budget airlines or airlines in the United States. It was as good as any other airline. The seats are comfortable and the airline attendants are not rude & surly. Very nice flight (s).

Spirit Airlines has a reputation for being a terrible, cheap airline, this is why. I took a gamble on them, having never flown with them before, and the flight got cancelled. First they delayed the flight about 4 times before finally canceling it because a flight attendant didn’t show up to work that day. That’s so stupid. When I asked a ticketing agent she said that’s “company policy”. A company policy that inconveniences hundreds of passengers because a single flight attendant didn’t show is ridiculous and inefficient. I will never, ever try flying Spirit Airlines again.

The traffic controllers had cancelled some flights, I wish they'd done it sooner so we didn't have to sit at the airport for 3 hours.

I liked that the crew looked well put together. I also liked that there were little turbulences.

The front desk personnel at ORF ticketing were the only good experience I had during my round trip. I encourage spirit to re-assess all aspects of their internal operations. This includes their website with constant issues connecting to their data base and questionable system practices. The employees of spirit airlines I will not comment on, as I believe primary issues had been a direct result of poor work conditions and expectations placed upon them. The holidays cause high emotions for everyone, this is an excellent time to take the opportunity to provide solutions for them, not take monetary advantage.

Delays due to a "power bank removal", no wifi, pilot said wrong arrival city, stewardess mumbled the word drinks as she rushed past, loud passengers with no enforcement of rules (blasting music out loud on their phones), screaming children

Flight was cancelled with no help From spirit or kayak. Please refund asap

A flight attendant was extremely friendly and offered to move me to a row that was less crowded

My flight was cancelled for “weather”. There was absolutely no bad weather along the course of my flight track. I missed my entire vacation with my family. I will never book a flight with spirit again

First time in a decade I threw up on the flight, turbulence was terrible!! The staff were kinda rude at times.

The most horrible flight ever not only Spirit delayed our flight 2 hours departure time for a 1 hour flight — that I could have driven FLL to TPA and spend less time on the road —- and they did the same on the return with 2-hr delay again!!! Then to top all, the rubber like and most unconfortable seats in the industry with no leg room!!! There should be an award for these kinds of companies measuring % of returning customers!!!
