Airline reviews

Pros: "Crew was tight, friendly, flight comfortable & painless."

Cons: "The plane had a mechanical issue that they needed to address (due to the fact that they prior crew did not address it) and we sat in the gate for 2 hours waiting. No worries water was offered by crew and the flight had no food."

Pros: "On time flight. We were even a little early."
Cons: "Those seats are just crammed in there aren’t they?"

Pros: "Pretty standard flight"
Cons: "Inconvenient timing and overcrowded with obnoxious children sitting on laps. No attempts made to change their behavior by crew or parents."

Pros: "Fine for a domestic flight. Normally, American Airlines offer a small snack to go with the drinks. But on this particular flight, they went the United way and offered nothing but drinks. Crew was pleasant enough during the flight, although they didn't greet half of the passengers entering or exiting the plane."
Cons: "Flight was a little late taking off and therefore getting to Denver. But there was no announcement about it. There was one announcement from the captain, but it was so soft that I couldn't hear anything. Upon landing and arriving at the gate, we stood there for a while with no lights on and seatbelt sign on, but no explanation of what was going on. There was no welcome to Denver message either. Maybe their announcement system was down."

Pros: "Not using kayak."
Cons: "Worst flights in history. It took three days to get from Italy to the US. Do not use kayak!"

Pros: "Great service in first class"
Cons: "N/A"

Cons: "The usual crowding in coach class."

Cons: "Aircraft issues, late on take off, a gate change, but the ticket against kept us informed"

Pros: "Things were all right on schedule and the plane was very updated and clean. I was thrilled with the movie selections and the food was better than average plane food."
Cons: "Bathrooms were in rough shape, would have liked to see those serviced in-flight so those of us using the space to do night-time routines like brushing our teeth and washing faces didn't have to deal with someone else's mess."

Pros: "Great service"

Pros: "Things went as they should have got a 2 hour flight."
Cons: "The inside of the plane around the air vents definitely could use some cleaning."

Pros: "Nice crew Spacious plane"

Pros: "The food and movies"
Cons: "The lack of communication while waiting to board about why plane was delayed even though it was already there. Service was ok, nothing stood out nor was extremely bad."

Pros: "The empty sit next to me"
Cons: "The very basic food. Having to argue to get extra water to drink when I got seriously dehidrated The limited choice in movies"

Pros: "Direct flight Chicago to Paris."
Cons: "Uncomfortable seating. Almost 2 hrs delay leaving Chicago forced us to miss train connection in Paris. Bad layover times to get back to the States, almost 9 hrs was the only choice available."

Pros: "The crew was amazing, flight was very smooth, arrived early, plane clean, service was great."
Cons: "For being in first class, my seat did not recline so I couldn't sleep and audio for my entertainment center was not working"

Pros: "On time"
Cons: "Cold cabin"

Pros: "Boarding was more efficient than I expected. And the leg room was very good, but the seats were narrow. Narrow seats made it a bit uncomfortable for a long 13 hour flight. Crew was efficient and very friendly."
Cons: "The sandwiches were too cold - actually had ice cycles. Narrow seatingwas constricting and entertainment wasn't varied enough."

Cons: "3rd flight in two weeks suck sitting next to a morbidly obese person. They should be forced to purchase two seats."

Pros: "The crew was amazing - agreeing to work extra because it was Christmas eve and they wanted us all to get to our destinations for Christmas. They were very gracious and helpful."
Cons: "We were over an hour late to leave. I understand the reason for the delay because of weather. What I was disappointed in is that the delay was not announced until our actual scheduled time to leave. It meant people coming to pick me up didn't get the change information in a timely manner."

Pros: "Flight crew had a great sense of humor - they were extra friendly while boarding as well, made traveling with AA the best! Boarding was delayed due to previous flight but our pilot even managed to get us to Denver early! Wish I could have this crew everywhere I go!"

Pros: "it was fine. flight left on time and the crew was nice."
Cons: "that you have to pay $100+ for economy plus to get the legroom you used to get for a regular ticket."

Pros: "Friendly crew. Due to the apparent regularity of excessively delayed American Airlines flights, they had the staff at O'hare bring a cart filled with cheap canned juice and Diet Soda to lessen the blow of their consistently delayed flights."
Cons: "Like every other American Airlines flight I've ever been on, it was delayed. Including the American flight from Denver to Chicago. We pay entirely too much money to these airlines for them to deliver such painfully mediocre service and consistently delayed flights. I recommend that this airline do a SERIOUS audit of their Preventative Maintenance/Service division across their hubs. If I fly American, I would bet my entire checking account that the plane will be delayed well over 2 hours."

Cons: "Missed that flight because my finair was delayed at Helsinki"

Pros: "Missed the flight. Money was not refunded."
Cons: "Nothing"

Pros: "More improved than the last trip I took with AA to Denver. Efficient boarding."

Pros: "We got to watch movies for free, and we got to eat twice as well."

Cons: "First, the original 90 minute layover became 8 hours with the old buy this scheduled ticket and 3 weeks later we will switch it to 7 hours. After a 8 hour red-eye, it was brutal. BA was an hour late taking off from London to Warsaw. The onboard experience was charge for everything. No sodas, water, nuts, etc. Oh and boarding, cmon. The gold, silver and special people go first. I think that was 5 people. The other 150 plus, you are on your own, go. You have your typical isle 5 person holding up the entire loading procedure, trying to get their oversized bag in the overhead, versus loading from the back. Wow."

Pros: "New Airbus Dreamliner is a nice plane."
Cons: "Not much"

Cons: "There was no wifi and no screen on the seat. I could not see the screen for the movie. Airline was old and also it took 2 hours to get going because they had to check the engine."

Cons: "Little guidelines for new comers especially while changing the flights."

Pros: "All the movies"
Cons: "Legroom"

Pros: "Very nice plane with a good entertainment system."
Cons: "The flight attendants seemed almost angry. Banging trays,. bumping carts into nearly every row and even skipping some rows on drink service."

Pros: "Nothing. AA is the worst airline. Period."
Cons: "Rude flight attendants, delayed flight (as always), just AWFUL."

Cons: "The flight left almost 6 hours late, and the delay was not directly due to weather. Another flight from and to the same airports left as scheduled 3 hours before this one finally left."

Pros: "The crew were exceptionally friendly and helpful. They made the negatives about the flight much more bearably be their excellence service whether during boarding, in flight, or after landing."
Cons: "I booked the flight originally through british airways and expected your standard, modern plane for cross atlantic travel. Boarding to find myself on a 767 designed (and likely built) in the 80s was rather disappointing."

Cons: "Could not read paper when passenger in front reclined seat. No space between rows."

Pros: "Flight not entirely sold out. So they let my 14 month grandson have an empty seat between my daughter and I. That was a great gift since he doesn't sleep and is jumping and crawling all over the place. And I'm sure the other passengers were breathing sighs of relief!! Also super smooth landing and nice flight attendants."
Cons: "Flying with an active 14 month old toddler boy and of his "stuff" is nothing less than anxiety provoking. Not much the airline can do.."

Pros: "The departure time. This left enough time to get to the airport and go through security without rushing!"
Cons: "Sitting in the middle Paying for luggage ( I wish Southwest flew out of ORD)"

Pros: "I liked sitting next to my friends."
Cons: "Lack of leg room"

Pros: "They showed American ninja warrior."
Cons: "Everything. The flight was delayed greatly even though the plane got to Chicago only slightly late. Then they make us board and just sit in the plane for an hour. Then finally we start moving, the plane is uncomfortably hot even with the air blowing on me, the flight attendants look like they hate their life, it was honestly horrible and I will never fly with American Airlines EVER again."

Pros: "World class"

Cons: "On time departure"

Cons: "More pretzels."

Pros: "Nothing"
Cons: "When I tried too cancel the flight. No body answered or responded too my emails. So I had too loose the 500 I spent on the flight even though I paid for the protection! I wasn’t even on the flight!"

Cons: "The flight was three hours late!!!!!!! I had to get on and get off the plane with all my stuff. This has financial implications on the ground later that evening in Uber Cost and I had to pay for the additional day for my car because I was not able to pick it up at the originally scheduled time. I contacted United and have not heard ANYTHING!!!!! Please help me get my money back!!!"

Cons: "Over two hours delayed. Had to carry on carry off my bags that were heavy. Messed up my schedule. Had to incur extra charges at San Diego destination due to the inconvenience."

Pros: "Emailing me with updates"

Pros: "The flight was very affordable and turned out to be great. I love the new United Basic Economy seats."

Albuquerque flght was still at gate when I got there, having run through airport along with several others. We were refused admission to plane despite delay being United's fault. Unacceptable! I will avoid flying United in the future whenever possible"

Pros: "Flight was wonderful!"

Pros: "I didn't fly.I bought the ticket for my son. He had no complaints. You should ask in your questionnaire if the booked flight was for self or someone else."

Cons: "How they canceled one of my flights just as I landed at my layover for that flight when I look back at Boston they had a direct flight ready for my destination. Very poor management I was stuck in Chicago with no money or food for hours then after they start boarding for my new flight they tell me that I may not be able to get on even with ticket in hand. It was a joke and very stressful"

Pros: "Boarding was uneventful, but I wish I could have gotten a gate check....I;m 76 and getting my bag above the seat is difficult. But the gate attendant said there was no gate check on that flight."
Cons: "I had a center seat and that is very uncomfortable for me."

Pros: "Got there on time."

Pros: "On-time departure from Cancun but early arrival in Denver (relatively mild jet stream?). Otherwise, fairly typical United cattle carrier."

Cons: "By removi g all inflyte movie and no hot food and no music your getting like Spirit. But cost alot more maby i need to go to them and just bring some food iam not electronics guy and most around me werent but a AM flight over 2 hrs should serve bot foid as well as a movie or at least have music to listen to"

Pros: "Use of my phone for boarding ticket"
Cons: "Sitting next to a large man who took 25% of my seat and space."

Cons: "My son ( a minor) was held over in Denver airport for over 12 hours because of delays and cancellations. Not once did your United crew or service workers offer him a meal voucher. This is absolutely wrong. This was my son's first flight alone and he also could not find any venders open to buy food. I will NEVER fly United again and will tell all friends and relatives about your inconsideration to minor passengers who are too shy to ask for help.!"

Pros: "United seems to be recycling which is a good thing."
Cons: "The obnoxious child sitting behind me. He kicked the seat and pulled on the tray."

Cons: "Need more leg room."

Pros: "Pilot was wonderful and did a fabulous job landing in the windy conditions."
Cons: "The flight attendant was dismissive and rude. The united terminal at DFW was terrible. Dirty, old and just plain disgusting. Craft was a bit run down and dirty as well"

Pros: "Instead of a 4 hour layover in Denver, I was easily able to get on an earlier flight to slc thank you to such a wonderful front desk agent. Even the crew members on board were so pleasant you could tell they truly enjoy their job and want to make for an enjoyable flight. Thank you United!! Will be flying with you again!!"

Pros: "Extremely friendly crew"
Cons: "No entertainment, but that is expected"

Pros: "Efficient boarding"
Cons: "Very rough flight but pilot did a good job of keeping passengers informed"

Pros: "My flight home was surprisingly faster than I thought it would take and the entire time I was comfortable and relaxed."

Pros: "Excellent service."

Pros: "The crew members were welcoming and the cabin was clean."
Cons: "Only limited drinks were available and then the flight attendant forgot to bring the water I requested. Thankfully it was a short flight, so it wasn't that big of a deal."

Pros: "Customer service at Dulles was helpful"
Cons: "My trip was jacked up on both ends, starting with cancelled flight at 11 p.m. the night before, phone calls to United to change flights on the way out, and then maintenance on the way back home, which caused me to miss my connection in Dulles. Horrible accommodations, bad replacement flights, baggage service in Syracuse was dishonest and apathetic. All around bad."

Pros: "Nothing, because I did not fly"
Cons: "Due to some reasons I want to change the destination, but it seems to cost me an extra amount of 230$. I just cancelled my trip and I dint fly neither my amount is refunded"

Pros: "Steamboat Springs, CO There were many CUBS fans on this flight! Good to leave rainy Chicago & arrive in dry Denver! Even though the plane was late, I was still able to catch my Alpine Taxi to Steamboat!"
Cons: "There should be a way to know when the bathroom is available!"

Cons: "The plane was over 2 hours late, putting our arrival at after 1 am. This made post flight transportation a problem."

Cons: "Should have been notified before heading to airport. No one wants to sit in a airport for three or more hours."

Pros: "The plane was very clean and seats seemed new. We left and arrived on schedule."
Cons: "Leg room seems to be shrinking. I would have liked to hear from the captain. I like hearing about what area we are traveling over periodically throughout the flight. I also like to hear the current weather forecast at the destination."

Pros: "Nothing"
Cons: "Worst customer service"

Cons: "The crew made us move from the seats I booked without a good explanation"

Pros: "Budget before adding bags"
Cons: "Bag costs Delay Airport I was stuck at - Chicago Very basic plane Poor info in airport - unnerving"

Pros: "This flight was ok but my history with frontier airlines is awful. I only flew them because it was the only option."
Cons: "Lack of customer focus or care. Hidden fees for everything."

Pros: "nothing"
Cons: "the fact that i was delayed more than 5 hours on the departure and more than 1 hour on the way back. Why is there an option for entertainment when none is provided? Also you need to pay for the food"

Pros: "It was cheap but still quality! Flight attendants were nice and friendly. The plane was clean and boarding went smoothly. Informed us what was going on at all times. I went without a carryon and just a personal bag. No Hassel about the size."

Pros: "The crew was great. That's about it."
Cons: "The plane had to turn back in the middle of the flight due to a mechanical issue. We were boarded on a new plane relatively quickly so that was nice and appreciated."

Pros: "Animal picture on tail of plane"
Cons: "20 minutes into flight had to return to Chicago due to mrchanical problem. Then had to wait 3 hours in terminal before could board new plane. Got to Denver 3 1/2 hours after expected arrival. Then wasn't even offered something free to drink on new flight. Bad PR for airline."

Cons: "Delay after delay without much updating"

Pros: "I liked the price of my ticket. Not having complimentary food and drink was OK to maintain the low ticket price."

Cons: "It was the scariest flight I've ever been on. In all my flying - easily over 150 flights - I've never been a flight that was that shakey. The landing was top 3 hardest landings ever too. When we landed I said "that was the worst flight I've ever been on" and every person in ear-shot (about 12 people) all looked back in uniformity and agreed."

Cons: "Food"

Cons: "Seats are not conftable"

Pros: "Crew service"
Cons: "Free drinks and Snacks weren't provided"

Pros: "The price of the ticket"
Cons: "The seats were awful, no padding what so ever!!!!"

Cons: "3 HR unknown delay"

Pros: "The lady who got placed next to me."
Cons: "Getting onto the flight not actually having a seat or boarding zone on my ticket. Also the trays are completely useless. And the on board food and drinks are Way over Priced and wasn't offered until almost the end of the flight. Over All I wouldn't choose this Flight again."

Pros: "Nothing."
Cons: "Rating on comfort, food, and entertainment. New seats are plastic, don't recline and have a tiny metal flap that replaces the tray table, can't even put a computer on it. If you want a seat with padding... $50 extra. Food is all for purchase, even water. Entertainment is non-existent. No tv, no WiFi, not even an earphone jack. Taken cheap airlines to a new level. With all the hidden fees you can fly a regular airline for the same price and keep your dignity. Last flight with frontier ever."

Pros: "Staff was professional and helpful"
Cons: "Seats too close to each other. Chairs hard. Cleanliness marginal"

Pros: "Not much It was just a flight"

Pros: "Not much"
Cons: "Uncomfortable seats charging $1.99 for a Coke. Price for tickets were high. Really don't like paying for seating."

Cons: "The crew had no idea what they were doing it or what was going on. They didn't tell us of delays until after the last departure time was passed, they gave confusing announcements, and took so long to distribute the food vouchers that all the restaurants in the airport were closed."

Cons: "Flight got cancelled, the trip I planned 2 months in advance and they said they couldn't fly me out till Monday and it was Wednesday, Frontier sucks"

Cons: "hard seats"

Pros: "The flights were great. Left on time and arrived early!"
Cons: "Nothing"

Pros: "Good flight"
Cons: "Just remember, you get what you pay for. My flight was $148 from Denver to Chicago on Frontier."

Pros: "The initial ticket price"
Cons: "The add on for a checked bag - $40! AND THEY wouldn't accept cash even though it's "good for all debts public and private"."

Cons: "The crew was acting quite unprofessionally regarding a few comments from another passenger, and one flight attendant spent the entire time flirting with the pilot. I couldn't even fit my normal size backpack under seat, let alone my legs. I spent the entire flight with my feet on top of my bag. I won't even get started on the extra fees. Frontier is "cheap" but not once you actually book."

Cons: "With having to pay for your seat when checking in, that should be included in the total fare."

Pros: "Flight attendants were nice no different than any other time I have flown on a plane"
Cons: "There were 2 small girls 3 seats in front of me and they screamed at the top of there lungs for most of the flight. Neither one of their parents seemed to be really bothered by it and so I think the flight attendants should have put an end to the screaming since the parents wouldn't. Also the kid that was sitting in the seat in front of me threw up and it dripped though his seat and onto my bag"

Cons: "Bad experience overall"

Cons: "we were delayed over 45 minutes and no one in the crew seemed to know what was going on"

Cons: "The boarding and exiting process was unapologetically slow. The cabin was super hot the entire trip and didnt feel there was enough circulation. There seats are horrible. The staff only came by once and completely skipped me and when i flagged here down, she was very annoyed."

Pros: "Initial cost of flight. Later disappointed that it was as expensive to check three bags."
Cons: "Seats were uncomfortable, mere plastic shells compared to other airlines and seats in our area did not recline. Very little legroom as rows seemed to be compressed. Being told we had to pay for checked or carry on luggage on-line so we checked three bags since we had to check one anyway. Then noting other passengers getting on the flight with bags they were putting in upper compartment without seeing how it had been verified that they had paid to bring on luggage to put in the overhead. I feel like a schmuck for paying for bags when it did not appear anyone was checking to see who paid and who didn't. Not even soft drinks were free."

Pros: "The flight was great and everything leading up to the luggage pick up was good. The flight landed a half hour early and the flight left on time. Getting the luggage took an hour and a half and they sent us back and forth between two different pickup locations. What should take 15 minutes took much longer than desired."

Pros: "2 of 2 trips, over an hour late due to time sitting on the tarmac."

Pros: "Easy check in, we took one check in bag instead of three carry-ons and paid online to keep the price under control."

Pros: "I will never fly Frontier again. Poor customer service. Poor baggage handling. Poor timeliness of flight and baggage delivery. Poor communication of flight delays and baggage mix-ups. Understaffed. Undertrained. Poor seats, particularly considering I paid for the best. Inadequate compensation for 8+ hour delay and missing baggage for 3 days. After all the nickel and diming for seats, baggage (checked AND carry on) it would have cost me less to fly my preferred carrier and avoided every hassle, not to mention the inadequate compensation (again). Horrible, horrible experience."

After all the nickel and diming for seats, baggage (checked AND carry on) it would have cost me less to fly my preferred carrier and avoided every hassle, not to mention the inadequate compensation (again). Horrible, horrible experience."

Cons: "Had to sit to wait fr long time to get to arrival gate after landing"

Pros: "Same as many other reviews, upset I had to pay extra just to select not a premium seat, but literally a seat on a flight I already paid for & pay to either check a bag or carry a bag on. I'll never fly frontier again & probably never book through kayak again either."

Cons: "Frontier airlines. Rigid and unable to admit that they made a mistake. Caution towards anyone who flies with their special low discount rates. Many opportunities were taken by company to recover discounted fare (and I am not referring to any baggage costs) Besides money, they ruined a special weekend through delays. Think twice! In fact, my comment is in reference to customer service in general. Everything is a fight now. I'm not a screamer, I'm rational. I laid out,clearly, where their policy was contradicted and that some empathy was in order and in the process was hung up on once and have not received a reply to my last email. If you gave no intention to achieve quality customer service, why pay for the department? Maybe they don't."

Cons: "Lost my luggage and people at check in were rude"

Pros: "Funny crew. Did not crash."
Cons: "Cramped, all the charges and steps involved checking in the day before."

Pros: "seat dont recline"
Cons: "pay for every thing even a drink seats dont recline"

Pros: "The crew were friendly and helpful"
Cons: "(a) No wifi (b) Being nickled and dimed for too many things (c) really uncomfortable plane. Even the $30 premium seats are terrible and don't recline If I had known about carry on and seat assignment fees I would have just flown on a different airline because there would have been no difference in price."

Cons: "The precline seats are uncomfortable, and seem closer than other airlines."

Pros: "This trip was on a newer airplane I believe as it seemed there was a little bit more leg room between rows/seats. Seats did seem a little bit more comfortable than the previous Spirit jet I flew on."
Cons: "Still seemed cramped in the seats with not much leg room. Seats did not recline at all"

Pros: "Staff very friendly and helpful"
Cons: "Seats uncomfortable"

Pros: "Got what paid for"

Pros: "Nothing"
Cons: "I arrived at the terminal three hours early, connecting from a non-Spirit flight from Central America. Spirit employees wouldn't check me in, saying they were too busy and I need to wait, but no worry, there's plenty of time. Asked again later and was told to check in online. Checked in online and was told (after the many upsell screens) that I couldn't print a boarding pass and needed to go to a Spirit counter. Went back to the Spirit gate and they said I hadn't checked in so they gave away my seat, and they didn't have another flight until tomorrow. Did I want it? Nope. Bought tickets on a real airline. Will never, ever travel with Spirit again."

Cons: "Online check in was great but after printing boarding pass at home still had to wait in long line to just check bag"

Pros: "Nothing bad, nothing outstanding either."
Cons: "With all the baggage fees and the hassle of having to go back and pay for bags online after purchasing tickets, I'll fly a major carrier next time. After crunching the numbers and inconvenience of it all, I didn't save anything by flying Spirit. You truly do get what you pay for...go cheap, get cheap."

Pros: "None"

Pros: "They shut the doors early I miss my flight they refused to give me a refund waste of money as usual"
Cons: "They shut the doors early I miss my flight they refused to give me a refund waste of money as usual"

Pros: "Not much"
Cons: "Cost of baggage Web site"

Pros: "I liked how peaceful it was. No crying or screaming children, no loud adults, no loud games. The flight crew were very polite, courteous, and showed compassion for the passengers. The air pressure wasn't to much. It was just right."
Cons: "No reclining seats."

Pros: "i was sent a message with a change or"
Cons: "the charge you 100 dollars for luggage.....plus sits before I know i paid the company 500 dollars, so if you were looking to save go somewhere else"

Cons: "The seats are cramped and on the way back, they canceled all flights back to Houston, causing us to pay an extra $600 in order to get home to work on Monday."

Cons: "Our return flight was cancelled and we received no phone call or email of any kind letting us know. We had a wasted trip to the airport and my buddies vacation time was up the next day so it put him in the hot seat at work. They were very unprofessional at the check in counter while we were trying to figure out what to do. My friend who we were going to see in Denver had flown spirit a few months before to come see me in Texas. And he had some unnecessary issues also with delays and unprofessional personnel. I won't be using them again. Use a different airline."

Pros: "Price was right"
Cons: "Reserved my seat but didn't get it; cramped."

Pros: "Ran on time. Crew was very polite. Flight also arrived early which was nice."

Pros: "FRIENDLY CREW"
Cons: "FLIGHT DELAYS"

Pros: "Ease and price, legroom was ample as well"
Cons: "I didn't like paying for my water"

Pros: "Pilots did an amazing job with category 3 landing."
Cons: "People were just walking onto plane without scanning in. Boarding attendants were allowing total chaos. Also, why so many flight attendants and crew onboard?"

Pros: "Nothing"
Cons: "Everything"

Pros: "On time! Flight was good. Good option for a good price."

Pros: "The price"
Cons: "The information"

Pros: "Cheap fare."
Cons: "Fees for everything."

Pros: "Everything was as expected. I highly recommend springing for the big seats on Spirit flights!!! It was well worth it."
Cons: "One small bag for a weekend trip is fine, but the price for anything extra is crazy expensive!!!"

Cons: "I'm not that large of a person, but I had absolutely no room. Tried to read magazine , no room. I did not like the super small tray table."

Pros: "Short Flight Good communication from the pilot - could have waited 15 - 20 min before actually telling us that we were starting the decent"
Cons: "I felt like a sardine. Sat between two large men, and I was SMUSHED. No comfortable positions - thank goodness the flight was short. The bathrooms were disgusting on the flight."

Pros: "It's a plane. It was a short flight- all was fine. It was cheap, and I didn't need any baggage, so Spirit is the best airline for that. You can't beat the price. Booked the night before- about 16 hours before the flight."

Pros: "Great overall experience, great price"

Pros: "The flight left on time-boarding was a breeze-the crew was professional and friendly-and the flight landed early. Great job!"

Pros: "The crew was friendly."
Cons: "Both of our flights were delayed for two hours with no explanation. Other airlines didn't seem to be having the same problems. It is rediculous that they charge for bags and that they are the only airline with a 40 pound weight limit when all of the others are 50 pounds. They charge $10 just to print the boarding passes at the airport. All of this they claim saves you money on the fare, but with all of the nickel and diming that they do to you after you purchase the ticket, it is much more affordable to go with another airline. I will choose some one else to fly with next time."

Pros: "Nothing"
Cons: "I wasnt allowed on my plane when it wasnt leaving for 43 minutes after i had arrived there. I would have been there the RECOMMENDED hour and a half early if i hadnt run into heavy traffic. Unfortunately, I only had 43 minutes before the plane left denver and the crew told me that i was late and wouldnt even give me the opportunity to try and get to the aircraft before it left. Then they told me that i could pay almost double what i had origionally spent on the flight to wait 4 hours for the next one with a 6 hour layover for thr connecting flight. I had then asked if it was possible to be reimbursed, the guy at the counter started laughing and said no it was my fault i was late. I have never been treated with such disrespect before in my life. I just dont understand, because no where does it say that if you're not there 50 minutes prior to the flight that you forfeit your flight. 50 minutes, i was there 43 minutes prior. Now i wont be able to visit my family for another year because i used my vacation time for that aweful experience with spirit ovwr 7 minutes. Then when i called kayak to explain to them what happened, they told me there was nothing they could do over and over again. Absolutely no help from either party."

Pros: "Crew was polite."
Cons: "The seats were horrible. I was aware that the Spirit seats would not recline but I did not know that they had so little padding. The ones with the gray backs we encountered on the flight to Denver were intolerable. The ones with the blue/black backs we encountered on the way back were better padded but still too uncomfortable for any flight more than an hour. I've encountered cement benches that were more comfortable. Never again."

Cons: "We booked and it took 30 minutes to move because of the AC"

Pros: "Everything was on time and as expected. The pilots were great and maneuvering around a storm outside of Denver."
Cons: "Nothing to dislike, really."

Pros: "Nothing except that the pilot didn't crash the plane."
Cons: "Everything"

Pros: "My flight TO Denver was fine. Nice new plane, crew was pleasant etc."
Cons: "My flight FROM Denver TO Houston was a nightmare. The plane was disgusting and smelled like dirty diapers. Everything was sticky and gross. I had to throw out the clothes I was wearing on the plane afterwards. I cannot believe the inconsistency. Never again will I fly Spirit."

Cons: "Flight kept being delayed and then it was cancelled."

Pros: "It was an absolute disaster coming into DIA due to weather, but the crew kept us updated on events and it was great to be informed of what was going on."

Cons: "Delayed flight, sat on Tarmac for 40 min.."

Pros: "Nothing!"
Cons: "They didn't let us know it was cancelled after 4 hours of waiting due to bad weather even though all the other flights were taking off."

Pros: "I like the cost for the flight and everyone was very nice."
Cons: "I did not like that there was a big delay in the departure of the fight, I did not get to my destination until very late; this caused me to miss several activities planned for my granddaughter's graduation. I would have liked for my bag to fly at a lower cost as well."

Pros: "Everything was pretty good. Plane was clean, boarding was fine. I think if you know going in, there are no extras, then you'll be perfectly content. Also, there was more room than expected so that was nice."
Cons: "I have to say the crews going there and back could use a little more professionalism and customer service training. I don't wan't to blanket criticize all of them because I didn't come into contact with everyone of them as much as others, but I was put off by the flight attendants attitudes. They don't help as much as on other airlines and don't pass out food to everyone like on other airlines, so when I do order and pay for it, I expect a pleasant reaction, not to made feel like a burden."

Pros: "I did not know what to expect flying first time on Spirit but was pleasantly surprised at the efficiency and kindness of the employees."
Cons: "I was not pleased to find that the weight for a bag was 40 lbs and was charged $25 on top of the $40 bag fee for an overweight bag. This must have been in the fine print for I did not see it and packed my bag to be less than 50 lbs. The seats have no leg room and I found them to be restrictive for my 5'2" frame. They do not recline due to the space "saving" efforts of the airline. If you are looking for "cheap" remember to add on all the fees charged for bags, select seats, beverages before comparing to other airlines."

Pros: "Cheap. Ramen noodles. My personal carry on fit."
Cons: "EVERYTHING ELSE SUCKED!!! I actually opted to drive home 1100 miles rather than fly back."

Pros: "The intial price of the ticket was good."
Cons: "The seating is a tight squeeze. The plane was also very dirty. I'm happy i brought some wipes so I could wipe off my tray before using it. The lady who I checked in my bag at the ticket counter was absolutely rude. She ruined my mood for the rest of the day. Also by the time I finished paying for my bad there and back I could of paid for a nicer flight. I know better for next time."

Pros: "that it was on time"

Pros: "Boarding was fast and easy"
Cons: "Flight was delayed as always and the lines were astronomical to check a bag and print a boarding pass. Something that costs way too much money to be such a hassle."

Cons: "my flight was late arriving to Houston ONE HOUR ... and plan was very noisy and .. PLUS MY FLIGHT FROM HOUSTON TO DENVER FEB 25 WAS OVER 2 HOURS LATE... I AM VERY UPSET SINCE I LOST A WHOLE DAY OF SKINNG WHICH I WAS TRYING TO DO AFTER 19 YEARS LATER .... RUINED MY 4 DAYS VICCATION WITH MY ELDER BROTHER....THEN GOING BACK HOME ALMOST ONE HOUR LATE............................................................................................................................................."

Pros: "The flight attendant was funny"
Cons: "They lost my baggage and sent it to a completely different state."

Pros: "same things I said before. would also like to add the ambient lighting and AC Was nice. Captain was friendly and so was the rest of the crew."
Cons: "same things I said before."

Cons: "I shouldn't have to pay for a carry on bag."
