Airline reviews

Pros: "It was standard AA service"
Cons: "After flying in Delta Comfort+, American’s forward economy section is just nothing."

Pros: "The crew was polite and professional"
Cons: "At Miami check in, American had 40-60 automated terminals available for self check, but only had EIGHT open for use. Caused a needless bottleneck and the transition from there to the bag drop was also poorly laid out and did not provide a logical nor efficient route from one to the other. fix it!"

Pros: "The flight itself was fine."
Cons: "The gate change was not announced on my phone app (changed from E7 to D49). I hate leaving out of Terminal E at MIA. There is no point to having TSA Pre-Check if you have to stand in line with people who don't have it. I have to remove my liquids and laptop. It's such a shabby, run-down terminal."

Pros: "No major screw-ups this time!"
Cons: "It's AA, let's not try too hard here."

Pros: "The plane looks like new. Great seats, phone and tablet holders at the seat back, USB outlet and a smooth flight."
Cons: "The WiFi did not work and so no entertainment for a flight of almost 4 hours."

Pros: "Friendly crew"
Cons: "Tight seating leg room non existent."

Pros: "Ahead of schedule"

Pros: "Wonderful, again. Will fly American any chance I get!"

Cons: "I signed up for a British Airways flight and American Airlines flew the route."

Cons: "the new seats are awful"

Cons: "let down by unattentive staff and felt more like a budget airline with the fact that you have to pay for meals"

Pros: "The fact that there were recently released movies in the system."
Cons: "4 1/2 hr delay in out trip. Losing our connection and rude crew."

Pros: "Tv and power outlets"
Cons: "This one attendant didn't get her name but was very cold to me"

Pros: "Crew was excellent."
Cons: "The connection in Chicago was 3 HOURS late with several gate changes. People on the desk were rude and never explained what was wrong. They didn't even announce the gate. change. I got it from Kayak."

Cons: "The flight was delayed 2.15 hours and didn't even offered water or anything, after a while they said if we wanted we could go out of the plane... really bad!"

Cons: "Nothing"

Pros: "Nothing"
Cons: "Pretty much everything"

Pros: "Good meals"
Cons: "Could not get seats together with my husband"

Cons: "Watched a very weird interaction between Muslim (with a hajib) women with a kiddo and desk crew. She wanted to sit next to her child on the flight and needed to switch seats to be able to. Woman was very gracious and understanding that she was asking for an accommodation. Ends up her flight to Philly had been moved to a different gate after they had found a volunteer to switch seats. Volunteer was totally unfazed but Desk crew made it seem as tho the Muslim mom was at fault for the time and trouble they had had to go through to accommodate her. She apologized profusely and was very appreciative for the trouble evernote had gone to for her. . As she walked away the crew looked at each other and shook their heads. Pretty crummy way to treat customers!"

Pros: "The crew for the most part were friendly. Boarding was easy enough"
Cons: "The one thing that stood out was that the flight attendants weren't offering water outside of the regular beverage service. I've never been on an international flight where there wasn't almost a constant flow of water. I was so parched after 8 hours. It seemed unusual. Also the seats are so small. I'm only 130 and 5'7" and it was a tough ride"

Pros: "Staff was professional. Beverages were plentiful. The quality of the wine was actually quite good."
Cons: "Not enough toilets for the number of passengers."

Pros: "Absolutely nothing. I was upgraded from business and would have been better in business."
Cons: "The seats were horrible. The tv screen was so old and small I could barely see anything, and the sound kept cutting out. The food was the same quality as business class with less choices and no menus. The staff kept forgetting to clear the table or refill my wine glass. I never had to use the call button on a flight before, but on this trip I was constantly hitting call or flagging people down. If I had actually paid for 1st class I would have been livid."

Cons: "It didn't happen"

Cons: "Didn't happen"

Pros: "No excuse on a night flight does the temperature to be 80 plus degrees on the plane."
Cons: "The plastic seats and extreme temperature was brutal. They shut the AC off of down somehow."

Pros: "I like AA because they are honest and kind. I received good value for my money."

Pros: "Everything"

Pros: "Nothing"
Cons: "All. The worst airline in the world"

Cons: "Uncomfortable seats Crying child"

Pros: "Segundo vieja con American Airlined y segundo fiasco. No vuelo más con esta ruta si la compañía que o uypera el vuelo es AA."
Cons: "Siempre embarque con retraso. Asiento poco cómodo, comida pobre, tripulación no habla español, el monitor de mi asiento el sonido no funcionaba correctamente y las películas escasas y fuera de temporada. En los dos vuelos que he realizado he tenido el mismo problema."

Pros: "Price, boarding process and seats were good"
Cons: "Crew was border line rude, and for sure neither attentive nor pleasant, food was really really bad."

Cons: "When we arrived at AirPort El Dorado, we discovered that our flight was cancelled/has been changed without warning us! They scheduled us a new flight with Vianca and Iberia: Bogotá-Madrid + Madrid-Brussels. My partner and I could not sit together on any of these flights! 1 of 10 hours and of 2 hours! I would NOT recommend AA to anyone! This was full responsability of AA!"

Pros: "Getting off of that plane."
Cons: "I understand delays happen and are sometimes out of your control. However, customer service is something that you can, should, and must control. I witnessed a lack of self control of the American employees (including a Supervisor) and every point of my trip w/your customers. I was embarrassed for the American executive team."

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)"

Cons: "the flight did not have charging areas on the plane for phones for the regular seating. also, the seating was much tighter and our arm rest was not functioning. On all the planes going to our destination the accommodations were much different."

Pros: "Very professional and friendly."
Cons: "N/A"

Pros: "Volare con American"
Cons: "No snacks offered! No alcohol drinks offered!"

Pros: "Nothing"
Cons: "That it got cancelled"

Cons: "The service was terrible, 4 hour traveling and not food."

Cons: "The delay, the landing and that you don't have at least one free documented baggage, that feels like a scam."

Pros: "One if the bathrooms was closed and a second one had no running water."

Pros: "They got me to my destination safely and the flight attendants were all very nice"
Cons: "United is cramped and very cheap. They don't provide much in terms of amenities compared to a lot of other airlines."

Cons: "delayed"

Pros: "We were on time"
Cons: "The annoying person next to me"

Pros: "Through security in 10 mins, plane left and landed on time. Great staff, well organized."
Cons: "Could use a vegan or vegetarian option for in flight meals?"

Pros: "Entertainment was fine."
Cons: "Boarding process at lax lumped groups 3,4,5 together, guaranteeing chaos. No UA employees provided effective communication of process. Line was so long nobody could hear. Flight delayed as well, insufficient planning"

Pros: "Amazing first time doing a first class flight and loved it!!! I would highly recommend it to my friends! Thank you"
Cons: "nothing"

Pros: "Just like what I wish, comfortable, on time."

Cons: "Did make this flight due to severe delay in Santa Barbara"

Pros: "NOTHING"
Cons: "My family was made to suffer due to United's inability to get all passengers off the plane in a timely manner. We all suffered for 25 minutes in a hot plane. We got nauseous from the heat . We ad to sleep on the floor of the airport in CO because we could not get a flight for that night. We missed an important Military graduation that is once in a Lifetime Experience. Your lack of customer service is appalling and I hope That I never have to experience that again."

Cons: "Booked a cheap flight but United wouldn't allow us to carry on our federally regulated carry on bags because we bought an economy class ticket. Made our flight expensive and will try and avoid United in our future flight plans"

Pros: "Absolutely nothing."
Cons: "Terrible. Flight was delayed by an hour. Gate was changed. Only reason I found out was because of email updates. It wasn't announced over the speaker. Although "comping" a film was a nice gesture, it would have been nice if the films started from the beginning. So it was basically pointless. Woman who sat next to me was a train wreck. When the snack/drink carts came around, I asked for a drink it was completely flat and disgusting. Just an overall terrible experience."

Pros: "Nothing."
Cons: "Flight delayed. Missed connection. Had to be rerouted and what was supposed to be a quick flight to Tampa turned into an all day and night nightmare."

Cons: "Was flying from LA and the plane got to the Denver airport on time but had to wait 20 mins on the track for a diff plane to leave so our plane had a place to pull up. This made me only have 15 mins to board my connecting flight to Minneapolis. After I rushed to the gate, United told me that they had a smaller plane so 28 people had to take a different flight. How does that happen? The $500 voucher they gave me did not make up for the time I had to fly to Chicago to make another connecting flight to get to Minneapolis. This was my second flight in one weekend as I was flying for an emergency. Both times United switched its gates for the flights last minute so I was scrambling to get to where I needed to go. Never again."

Pros: "Good flight but the planes are definitely older and a little more run down."

Pros: "Complimentary snack and beverage."
Cons: "The boarding lines were confusing and crowded. Most call up groups when it's their time. The lines were laid out well but no space to line up so it was a jumbled mess after about four people."

Pros: "They crew tried to help us as much as they could given the fact that United computers were down and we couldn't go anywhere for 3 hours."
Cons: "Because both our Air China flights were late, we had to RUSH all the way across LAX, only to find out United's computer systems were down, then wait 3 hours to leave."

Pros: "I need a refund for all the inconvenience"
Cons: "Mess everything"

Pros: "First time I used this airline and will start to use it more often. Very pleased with all services."

Cons: "Having my flight delayed to the point I had 5 minutes after we landed to try and run like Carl Lewis to the next gate. DAMN NEAR missing my next flight."

Pros: "Sucks"

Pros: "We were delayed coming into Denver for connecting flight into KC, but they held the connecting flight for those of us getting in a bit late. I appreciated that."

Pros: "It was a pleasant flight"
Cons: "I couldn't connect to Wifi"

Pros: "Everyone was helpful. And professional"

Pros: "Made it to Denver."
Cons: "Agents were not communicative with boarding passengers. Flight was delayed substantially."

Cons: "On all 4 of my United flights this past week, I could not connect to the peivate screening for longer than 23 minutes. A bit annoying really."

Pros: "Nice, big plane"
Cons: "The entertainment went out."

Cons: "I missed my connection in DEN to DSM by MINUTES!!! The flight crew from OAX to DEN would NOT ask for the flight to DSM to wait. We were only 2gates away!!! So much for the friendly skies."

Pros: "First time on a 777. It was HUUUUUUGE."
Cons: "Snack selection a little too high class for my liking."

Pros: "Nice plane very smooth flight"
Cons: "Plane was late and missed connection to Wichita"

Pros: "We appreciated the free wifi and programs on the Wichita to Denver flight. After landing in Denver, my husband's back was hurting and they upgraded our seats for free."
Cons: "Sadly, there was no free wifi on the longer flights from Denver to Los Angeles."

Pros: "The improved United iPad / iPhone app is interesting and our aircraft had AC power outlets between the seats (in a hard-to-reach location). USB jacks on the seat backs are much more preferable."

Pros: "On time"

Pros: "Love united."

Pros: "N/a"
Cons: "N/a"

Cons: "I was charged $7 for the TV and it should have been $5 as my flight was less than 2 hours and the TV kept going out."

Pros: "Not at all, crew over fueled the plane and delayed for 1 1/2 hours"
Cons: "That I missed my next flight, and no one cared to attend those who were on the Kay over, in Denver Colorado the united customer care was extremely rude to the 6 ppl"

Pros: "Coming home"

Pros: "It was straight forward flight"

Pros: "Absolutely nothing about this experience has been good."
Cons: "Flight delayed 4 times as of 11:40pm, the flight was supposed to leave at 8:10. At this point we have lost a non refundable rental car reservation and a non refundable hotel reservation and not a single person at the "customer service center" could even offer an apology or a suggestion as to what our next option would be, given that we are meant to be at a wedding in the Denver area in the morning. The aircraft is apparently pulling up as I type this, but that doesn't negate the fact that we are now getting no sleep, and losing a significant amount of money in reservations because we will not arrive on time. Please advise and rectify."

Pros: "We were not sitting together the agent was able to sit us together. Not only this but I wanted a window seat and she also was able to do this"

Pros: "Nothing"
Cons: "Having to cancel my flight and book another."

Pros: "The boarding was ok"
Cons: "The entertainment was terrible you couldn't watch anything but direct tv commercials no wifi or anything they ask you to perches it but aren't we paying enough atleast to have a single movie or tv show but no we get commercials the whole flight"

Pros: "All went well. Pleasant attendants."

Pros: "Seats we okay, and head rest was comfy"
Cons: "Flight attendants not the friendliest..."

Cons: "The crew was very non polite!. The flight was delayed. Asked for help from crew and she answered me with bad altitude. Never go with them again!!!!."

Pros: "The food."

Pros: "Flight was on time, crew was courteous and polite."
Cons: "They ran out of overhead bin fast. No on board TV"

Pros: "I like the fact the plane ride was always smooth and always early on arrivals."
Cons: "The seats are too small and not enough leg room."

Pros: "The staff on this flight were so friendly! Genuinely cared and that's always refreshing :)"

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: "Short-staffed, so short tempered workers.kiosks did not work. Nickled and dimed on everything. Like flying in prison. No light and a cold hard bench seat. Awful."

Pros: "Staff was pleasant"
Cons: "Seats are a bit small and the tray tables even smaller. It felt tight!"

Pros: "Staff and crew were wonderful."
Cons: "2 hour flight delay getting out of Denver due to no staff available to load/unload baggage was pathetic. I have had more comfortable wooden seat to sit on, and a charge for everything except water. Frontier needs to work on the issues, I will probably steer clear from using Frontier in the future."

Pros: "Little"
Cons: "Seats are aweful. Charged bags, especially carry on are deceptive. Flight late"

Pros: "I got from denver to chicago and back to denver."
Cons: "The baggage pricing was unclear about it being only one way. The price difference between Frontier and others was quickly eliminated when we needed to pay for our carry on to fly home. We were also delayed on take off and landing both times and as far as I can tell on every frontier flight I have taken in the past few years. It has come to a head and I don't thing that I will be flying Frontier again, this was the last straw."

Pros: "They are charge me for carry bag $40"
Cons: "They are charge me for carry bag $40 I book and pay online ticket $60 only Thank tto"

Pros: "That I got home."
Cons: "The horrible seats, no space, everything has a cost from soft drinks to carry-on. The one inexpensive flight ended up costing another $86 and that wasn't any food or drinks. Additionally when you check in they lead you to believe you HAVE to buy a $9 seat because nothing else is available when on reality, if you don't pay the seat costs 0 at the gate. Never again Frontier!"

Pros: "Once the aircraft arrived at the gate, the crew efficiently loaded the people onboard, and we left very quickly"
Cons: "The fact that there were no updates, until the departure time was exceeded. It was apparent that 1 hour prior to the delayed departure, when the aircraft was not there, that it would be delayed. But no announcement was given to people waiting until after the 2nd departure time, and by that time people were pretty upset."

Pros: "The crew"
Cons: "My flight was over three hours late. There was no compensation for anything, as well as no explanation as to the delay."

Pros: "Nothing!!!! Never will fly with Frontier again!"
Cons: "Poor communication poor customer service extreme long what on land both deporting and landing. Wth No apologies!"

Cons: "Late late late arrival."

Cons: "horrible accommodation theres a reason the flights are cheap they charge 45 bucks to check a bag so if u have to check luggage u might as well get a better airline. they had only like 3 gates at the airport boarding and exits u have to wait an hour and half on the tarmak. also flight got delayed and the didnt even say anything until it was our original departure time"

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: "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: "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"

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: "Seats are not conftable"

Pros: "On time, friendly and affordable prices"
Cons: "Not very clean, the airplane was messy"

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

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: "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."

Cons: "The aircraft was freezing. The water was not complementary and I didn’t have a card to pay with I only had cash. The seat was extremely hard and uncomfortable. The flight was last taking off and landing."

Pros: "Staff was excellent! Very attentive and accommodating. They care about their passengers!"
Cons: "The seats were so close together near the back of the plane that we could not put our laptop on the tray in front of us. Also the seats did not recline!"

Pros: "About the only thing that I can say I liked is, the boarding process went smothly for me & my luggage was on time."
Cons: "Where to start... paid more in bag fees & to get an isle seat for each(4)flights than I did for damn plane ticket! Flights delayed 4hrs another flight in same trip delayed 2 hours. Staff wasn't interactive/friendly I'd say 6/10 were nice. Asked for an isle seat the person helping at counter, said I'd have to pay to upgrade. Seriously- upgrade for isle seat!! I paid to have an isle seat on all 4 flights(I'm a disabled vet who was injured in the line of duty) I need easy access to toilets I'm unable to crawl over people, in turn need idle seat). Paid for isle seat all 4 flights- just to see the flights were super empty, people were sitting where they wanted anyway. Thanks for taking my $ for the seats tho spirit:-|. Staff wasn't that friendly compared to other airlines I've flown on. Not food. No entertainment on flight. Not worth it. If they don't do better business they won't last long I feel. There is potential just needs some work!"

Cons: "I didn't like the baggage policy. I didn't like the check in policy or the fact that they don't support TSA precheck because they hope to sell you on an additional fee that will get you through a prority lane. I didn't like the seats which are hard plastic, close together, and don't recline. I didn't like the mini tray table that wouldn't support my laptop so I couldn't work. I didn't like that Spirit falsely advertises with the tag line "LESS MONEY, MORE GO" when the base fare for my connecting flight on this sub-par airline was more expensive than a direct flight on a better airline-before the other fees were added."

Pros: "Plane's leather seats were comfortable and not as squashed as I thought they'd be. After I deplaned, I was lugging a heavy bag. One of the staffers insisted on carrying it to the gate entrance, then called over a wheelchair that was free, saying "That bag's way too heavy for you to carry that far." (to baggage claim) I was a little embarrassed -- but SOOO grateful! Thoughtful people like this make me want to keep using Spirit."

Pros: "It was either on time, or early. And, the price was right."

Pros: "the price"
Cons: "too cramped/ Plane felt rickety, even when there was clear skies. Seats were uncomfortable with no head support. No tv. When the trays behind were down could feel it in my back"

Pros: "I love the price"
Cons: "The seats, my flight was 2 hours, I wanted to take a nap but sets are so cheap made cannot recline and are uncomfortable. I will not fly spirit airlines for more than 3 hours"

Pros: "N/A"
Cons: "On top of the long lines, the flight was cancelled without any explanation 20 minutes before boarding. We were forced to walk all the way back to the airport entrance, but weren't helped at the Spirit ticket counter. Instead, we were given a card with a phone number to call in order to try and book ourselves another flight. We weren't able to get a flight until the next day with a different airline. It was a very disappointing experience, which created a terrible start to our trip. We will never fly Spirit again due to the unprofessional manner in which we were inconvenienced."

Cons: "Hidden fees for bags and seat assignments."

Cons: "My flight was cancelled. Why are you asking for a review????"

Pros: "Clean plane"
Cons: "You charged an extra $30 for luggage. I couldn't feed my kids lunch!!!! Terrible customer service from Dania and a lady named Nueua(?) in Chicago at the Spirit airlines check in desk. Unacceptable lack of compassion."

Pros: "Easy check in. No frills. Polite crew."
Cons: "Website crashed when checking in and I had to call because bags did not get checked"

Pros: "Flight crew was nice, captain did a fine job"
Cons: "Last minute gate change, seats dont recline"

Pros: "I could buy the exit row."
Cons: "Gate crew was uninformed as to why our flight was delayed and could n't get that information. Boarding process was very slow given we were already an hour late."

Pros: "The flight was fine and as expected."
Cons: "We sat in the terminal for over an hour after our plane was scheduled to take off and weren't given any information about when our plane would arrive. It was frustrating."

Pros: "I liked that I eventually made it back to Denver"
Cons: "The fact that the delay was all based on Spirit not being able to properly maintain their aircrafts and gates. The hour and a half delay that ultimately made me late to work the next day was not even due to weather issues. I blame spirit for the inconvenience and this will certainly effect my future decisions to fly with spirit."

Cons: "The seats were too close to the seat in front."

Cons: "Three times my departure time changed"

Pros: "Inexpensive price, great crew, the flight was to short for entertainment or needing food."
Cons: "Cramped quarters."

Pros: "Not much."
Cons: "None of the seats had a menu or magazine in them, only the safety guide. There were wrappers with old gum in them in the seats. Any food was over $5. The flight attendant tried to be funny way too many times and he wasnt funy."

Cons: "Delayed over an hour and they oversold the flight by TEN seats"

Pros: "Good service, enjoyable flight"
Cons: "Couldn't check in more than 3 hours early"

Pros: "Our flight got cancelled about 1 hour after it was supposed to departure, due to mechanical issues. Since Spirit doesn't have many airplanes we were redirected to rebook our flight which would not get us anywhere until Monday morning, if we use Spirit. They did offered flights with other airlines, but of course those were gone fast. I missed a race, asked if they could refund at least part of that fee and was told no. Crew was nice, honest and helpful."
Cons: "The honesty of the crew."

Cons: "Spirit airlines employees are not friendly and difficult to deal with. Were not accommodating"

Pros: "Price"
Cons: "Managed to catch a virus so couldn't travel (doctor's orders). Partial credit was given when I'd much rather just have a refund."

Cons: "Delayed for no reason"

Cons: "Still look for the first on time flight, no luck so far"

Cons: "The additional charges. Plus all of the talking, and people getting up out of their seats."

Cons: "In time"

Pros: "Everything went smooth. Cheap."
Cons: "The seats are small and cramped. They charge for all baggage except for a single personal item of something like 12"x14"16"."

Pros: "crew is very cute and make funny joke , to make us relax, i enjoy a lots"
Cons: "check in luggage is too expensive."

Cons: "Flight cancelled with no warning. Waited an hour and a half in line at the ticketing booth to be re-booked. Some people on my flight weren't able to be re-booked at had to fly out the next day--all of this happening at 8AM. I'll never fly Spirit again."

Pros: "The Captain and crew were terrific"
Cons: "Ours was a connecting flight and we were asked to disembark the plane versus staying on it. Once the plane was empty boarding started again. The seats do not recline and there was no wifi. We arrived two hours late due to weather and backed up gates (not airlines fault but still frustrating)."

Pros: "Flight attendants were nice."
Cons: "Seating was very cramped. Hidden costs everywhere, which jack up the actual cost of the flight significantly. Probably won't fly with them again."

Pros: "Staff is good. Suggestion is to check on needs for bottled water. Aisles are pretty tight so having the signage on when lavatories available is good."

Cons: "Waited for over an hour for a crew to get there to man the flight."

Cons: "See above"

Cons: "This was one of the worst experiences I have ever had traveling. This airline is a scam."

Pros: "On time."
Cons: "Seat and tray table were dirty."

Pros: "The flight seemed exceptionally smooth to me, including the take off and landing. Pilot seemed very experienced, competent and professional. I felt safe."
Cons: "Really? I can't get a free glass of water? Really?"

Pros: "Flight was on time, boarded on time, and arrived at destination 20 minutes early"

Cons: "Excess charges. Seats unvomfortable!"

Pros: "Flight and landing were great ... Kudos to the pilot!"
Cons: "Baggage restrictions are pretty ridiculous. Never saw seats that DON'T recline before!"

Pros: "on time"
Cons: "crew rude, expensive bag fees, crappy plane"

Cons: "Don't like being nickeled and dimed for basic services."

Pros: "It was easy to book the flight via the internet."
Cons: "Flight was cancelled due to weather but next flight offered was 4 days later.... Only option was to take the partial refund when I should have been give a full refund and buy a very expensive last minute ticket on another airlines."

Pros: "They gave me a refund"
Cons: "They did not have another flight for me for another week or so. Had to drive from Chicago to Denver. They did not try to put me on another airline either. You get what you pay for with these low budget airlines."

Cons: "We missed this flight because they close the doors VERY early... much earlier than other airlines. They also charge you for carry on bags and if we'd made the flight, probably oxygen. Never had a worse experience with any airline. Will never fly them again."

Cons: "Long lines everywhere"
