Pros: "Everything was great"
Cons: "Nothing"

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: "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: "Flight was on time through United since we had to be rescheduled from our original flight with American."

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

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: "Everybody was nice my ride was comfortable and they treat me with respect"
Cons: "I like everything"

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."

Cons: "Constant delays and cancellenations"

Cons: "Im still in dallas.....very angry"

Pros: "The movies"
Cons: "Everything else"

Pros: "That I got a soda"
Cons: "Delayed at Ohare by an hour. Sitting on the Tarmac for a half hour in Reagan, waiting for a gate. This was our leg back to DC, after our leg to Chicago four days previously. On that trip I did a review and gave the whole trip a 1 out of 5 stars. That trip was the trip from hell, with delays, waiting on the Tarmac, deplaning, almost cancelled, more waiting on the Tarmac, wheels up in Reagan, wheels down in ORD, and then more Tarmac waiting for a gate. So I was already more than perturbed when this trip had similar outcomes."

Pros: "Nothing"
Cons: "Flight attendants passing out drinks completely skipped us, even though we were looking right at her."

Pros: "Nothing . Flight was cancelled"
Cons: "Refund my money!"

Pros: "Stuck in Chicago. Never made it to Denver because of weather. Had to get hotel."
Cons: "Better accommodations by United."

Cons: "It sucked in many ways. But that wasn't united's fault. The weather was threatening lightning in Denver and of course because of that the world stops turning."

Pros: "Delayed. Bagage mis-rerouted."
Cons: "Be honest when bags are not routed correctly after assuring passenger twice that bags will be at the same airport they were re-routed too. Do not ask passengers for a bag delivery fee when the mistake was United's. Keep passengers informed of delayed flight and keep inconvenience to a minimum."

Cons: "It’s just crowded. The crew was great. Safe landing"

Pros: "Crew was nice and very efficient"
Cons: "Maintenance didn't have plane ready to depart on time"

Cons: "First flight of the day and there aren't enough floor assistants to address the sea of blinking red check-in kiosks. One poor soul is running around frantically trying to address all the check-in issues Pre-TSA doesn't start before our 5:15AM flight so after walking all the way down to the Pre-TSA checkpoint, we encountered a sign redirecting us back the normal tsa checkpoint which was overflowing with late check-in customers upset with the long kiosk check in delays"

Pros: "Everyone was really nice, and there was a decent amount of leg room etc."
Cons: "I honestly can't say that I have any complaints about it. Thank you. :)"

Cons: "Placed in middle seat with no options for isle or window due to my ticket. No problem with that if the people next to me were not so big. Young woman to my left by window was tall and broad and slept but took up all elbow and shoulder space. Guy to my right was very obese, sweaty so kept wiping his neck, head, and face with a cloth. Also had terrible body odor. I spent the entire flight in a narrow middle seat, hunching my shoulders due to lack of space. Both people taking up some of what little room I had."

Cons: "We were delayed in Chicago due to weather coming home from Europe. We were not allowed to use the business class lounge even though we paid for business class tix. My family is still sitting in the airport waiting on their flight to dallas. We have been up now for over 24 hours. We should be allowed to be someplace comfortable for the price of the business class tickets. poor form on Lufthansa’s part."

Cons: "Delays"

Pros: "Fast boarding and friendly staff."

Pros: "We had no difficulties and the crew was friendly and helpful."

Pros: "I will try to avoid Ohare in the future. Long wait to take off. Had to RUN to make the connection. Again."

Pros: "Flight left the gate on time."

Pros: "It was on time."

Cons: "I want to clarify that I boough tiquests with Lufthansa not with United... and I had to travel United most of the time to Africa and Bach to the USA... united socks terrible ... bad food and old plain to cross the Atlantic... besides the service and the bad actitude of the employees... when I travel international I want only Lufthansa. So, kayak you tricked me ....horribly!"

Cons: "internet & movies intermittently worked"

Pros: "Everyone was very respectful"
Cons: "Sight delay and having to pay for internet"

Cons: "This flight was canceled because my initial flight was canceled by united and then I could not take the rebooked flight so I could not keep the seats together with the travellers I was with and then was placed in the back of the plane. When my flight was canceled initially no one informed me that my return ticket would be canceled which I specifically asked about. I hope never to fly united again. The day to day staff at ohare and on flight were good and courteous."

Cons: "The boarding process is horrible. You have to stand in lines that disrupt the other people trying to navigate through the airport."

Pros: "The boarding and check-in process was quick and seamless. The crew was attentive, friendly, and informative. Ohare airport has Garters popcorn!!!!"
Cons: "Seating was a little cramped, even for a small guy like me, and the only way to watch anything on the small screens provided on seats in front of you, is to pay. Honestly, I know that everything is about the bottom line, but you can at least provide 1 free movie or Channel and charge for optional premium material."

Pros: "The crew was polite and offered an extra six ounces of water in addition to the usual beverage service. The flight departed and arrived on time, which is a rarity when dealing with ORD."
Cons: "The cabin was near 80 degrees Fahrenheit for about 30 minutes of boarding. During the boarding process and taxiing, the DirecTV add ran theee times. The commercial was annoying and loud. Once would be enough."

Pros: "Was able to fly standby and get home earlier. Crew was nice and friendly."
Cons: "Slept most of the way, but this plane didn't have television screens, so limited entertainment options."

Pros: "Very windy decent into denver but pilots and crew were great."

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: "The fact that priceline said there was nothing they could do."
Cons: "The fact that my pregnant wife and i were stranded in la guardia airlort and had to shovel out 800 dollars for last minute one way flights."

Pros: "Friendly crew."
Cons: "Passengers are stowing personal items/multiple bags in the overhead bins. This is an ongoing problem that needs attention. Armrest protocol should be made explicit. My in-flight entertainment control was covered by the passenger next to me the entire flight."

Pros: "United payed for the room and 20 bucks for food."
Cons: "Late. Missed the connection to Gillette and had to stay overnight."

Cons: "The flight delay and my missed / delayed luggage."

Pros: "It was Great Thank you"

Cons: "Delayed, missed connector flight to billings had to spend night in airport. Flight delayed 2hours to billings the next day. Worst flying experience ever will never fly United again!"

Pros: "Flight ahead of schedule. Friendly crew - got a full can of soda!! Good to see small snack reintroduced."
Cons: "Felt very cramped as was a full flight. No personal entertainment available, unless you paid for DirecTV."

Cons: "I missed my flight to San Diego from a connecting flight by a few minutes. Now I have to sit in the airport for over three hours waiting for my next flight.. not to mention it's my bday. Thanks United."

Cons: "Wish the seats were a bit more comfortable on frontier. And had to pay for carry ons. Will never ride frontier again."

Cons: "45 minutes late taking off"

Pros: "New, clean United planes! Happy crew! Snacks!"

Cons: "My boarding pass was not scanning which was holding up the line. A second person came over to approve me getting on the plane. That person made me check the size of my carry on bag, which had gotten bigger from some things I purchased in the airport but was just a touch too large for their sizer. She attempted to check the bag meaning I wouldn't have it until my final destination, which I was NOT ok with for two reasons. One was i had a 3 hour layover after this flight and needed work materials inside. The second was i was on a time crunch to get my ride at my final destination and was only traveling with carry on. She was very rude and insitant on it fitting inside the sizer as she stood over me with the tag to check my bag. I managed to take some things out that I moved into my backpack, which meant I had to awkwardly carry my blanket and travel pillow onto the plane. The most frustrating part was when I got on the plane, it was oversized top carryon bins, so the extra inch my bag grew would have been fine. Because of the time it took me to rearrange, i was the last one on the plane and all the bins had been filled with tiny second bags, but a few people on the plane had seen what happened and they rearranged a space for me. Also my video screen was broken and everyone else's worked. And there were two screaming babies around me the whole flight, but that is no one's fault."

Pros: "That we got a standby flight 6 hours earlier than our scheduled 12 hour layover. This plane was far better, newer and nicer than our international flight from London. UA929 was the WORST!"
Cons: "Snack chips don't qualify as food. Only water provided free. Out of all the star alliance members, United is the worst. We will try to not fly united again. Only entertainment you have to pay extra for. The international flight UA929 was the WORST. Old enough to all have the loop playing screens and mine didn't even work."

Pros: "Customer service"
Cons: "Delays. More than an hour and missing our connection in Denver which made us miss our car reservation and had to pay double for another car at the last moment"

Pros: "I liked arriving home in a timely fashion."
Cons: "The first gate agent responding flatly, "I have NO idea." to a gate change question. OR the Mother Superior flight attendants that couldn't wait to point and nag about seat backs and tray tables. I wonder if either of the women noticed they were talking to someone who wasnt't an English speaker? United needs to fly Southwest to learn the right way to do things."

Pros: "Crew was great and the boarding staff was very friendly."
Cons: "Flight was delayed"

Pros: "The flight attendants were all super kind."

Cons: "United is a horrible excuse for a company. 3 mechanical delays ultmately causing us to miss a wedding which was the reason for our trip. A 5 hour delay out and an overnight delay in the way home. We slept on the floor in the airport- one thing for us but disgusting to see United allowed this for elderly and families with toddlers and babies. The third mechanical delay occurred after we were finally bored and on the runway and they wouldn't let us deplane. Never have I been so terrified to fly."

Pros: "The flight is comfortable and the no hidden fees."

Pros: "The flight attendant finally took care of it after I complained a couple of times."
Cons: "That you changed our seats, and, that there was no room in any of the overhead bins. So, the flight attendant told me that I needed to fight my way through the people coming toward me back up the aisle and check every overhead bin all the way back up to see if there was room for my one suitcase. Others had brought more than one bag up there. Finally they checked my one carry on bag. The ride was also really bumpy, worst that we've ever experienced. But that was due to weather conditions."

Pros: "1st time I ever watched the safety/instructional video. Great job because it is important stuff and I saw others paying attention as well!"

Cons: "When the guy in front of me reclined his seat, there was no leg room. Today, I literally have bruises on my knees....ridiculous '"

Cons: "Not much. Brand new 737-800 that was the most cramped uncomfortable cabin/seats I've ever been in next to a commuter flight. Middle seat in the last row no recline didn't help. And my knees were up against the seat in front of me all the way. Was battling back cramps and spasms. Felt like a sardine. And we got no beverage service"

Cons: "Check in"

Pros: "Nothing"
Cons: "Delays, gate changes, lack of notification, last minute changes."

Pros: "Absolutely nothing"
Cons: "Excessive carryon bag charges and delayed flight"

Pros: "No muss, no fuss. Efficient and friendly crew. Flight was on time and we knew there would be extra charges for carry on baggage and food/drink beforehand."
Cons: "Seats did not recline. Tray tables were small. Under seat storage was limited and an average backpack barely fits."

Cons: "$45.00 for a bag is rediculous."

Pros: "It was very good! I liked it."

Cons: "We were delayed by 1hr and 45 min because a flight atttendant was not at the airport."

Cons: "Airline did not let us fly 45 min prior to the departing time, we were a party of 10 people; half of us checked in online and had payed baggage fees online but when ww got to the counter airline assosiate said we did not check in. Not only dod we loose our tickets but also the money for the fees we had already payed for. I had an uderstandong that the gates closed 10 min prior not 45. We had to fly becuase we had an emergency and this inconvinience just made our experince horrible. Defenetly dissapointed."

Pros: "What I liked? That the flight ended and I could get off the plane."
Cons: "They charged to pick seats. They charged to carry on a bag. They charged for any drinks. The seats had NO padding. The seats didn't recline. The gate at O'Hare was dark and dirty. The travelers in my flight would have scared the residents of Mos Eisley."

Pros: "Getting off the plane"
Cons: "Being in the plane"

Pros: "price, updates and friendliness"

Pros: "attendants were friendly, patient and in good humour."
Cons: "cramped, no room. high priced snacks and bevs,"

Cons: "Safe and it was on time"

Pros: "We landed early to and from that was nice.. The crew was very nice.."
Cons: "Had to pay for coffee other than that it was great"

Cons: "Lost my baggage after 2 hour delay. No attempt by airline to assist the customer or compensate the customer after clear mishandling by the airline."

Cons: "Terrible service from Denver. Missed flight due to Frontier check in desks being overwhelmed. Was there two hours early, told to go to outside curbside check in. Terrible delays when returning to Denver on the plane. Was held on the aircraft for 40 minutes before they could get us off. Bad experience. Won't be flying frontier again."

Cons: "Terrible information and no service."

Pros: "I am sitting at the gate 4 hours delayed"
Cons: "Nothing what a disaster"

Pros: "everything went just as planned, everyone with Frontier was on point"

Cons: "I find the Frontîer website difficult to use for check -in & getting boarding passes"

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: "Seats were more comfortable than I expected"
Cons: "Flight was delayed more than 2 hours."

Pros: "The flight crew was kind, attentive, and good listeners. I didn't have food but the menu looked good. The comfort was good for I paid for. My flight did not have entertainment. Overall, a positive experience. Even the check-in counter crew was stress because of all the delays they kept their head and even smiled. I'm very grateful for their professionalism. Our pilots were the best pilots I have had and I love to travel."
Cons: "I had one update about the flight delay but be a useful there were so many delays it was hard to find a place to get comfortable. I still do not understand how Denver's plane was an hour late. Maybe a little more communication and a safe, secure backup plane."

Cons: "Our flight was delayed, which I understand was due to weather and no fault of Frontier, but I was told, moments before I stepped on board, that my bag needed to be checked. I paid the full carry-on fee but was not credited the amount for having the bag checked. We were then delayed even longer on the runway. The flight itself was very rough and we had about an hour straight of turbulence. Then we landed and were stuck on the runway for an hour and a half! While we were stuck, there was a loud beeping sound that played the entire time we sat there! We received one update from the captain and flight attendants while we were waiting. The flight attendant came on the speaker and told us we couldn't move because everyone's seat belt was not fastened. They were very rude. I can honestly say that I will not fly Frontier in the future!"

Cons: "Late late late arrival."

Pros: "Nothing."
Cons: "waiting waiting waiting. Little communication on flight status. Got to my detonation 2.5 hours later than planned. Terrible"

Cons: "Take off was an hour late. We sat in the middle of the runway for an hour"

Pros: "Newer aircraft."
Cons: "Had to pay for sift drinks, sparking water, etc. No entertainment. Seats do not recline."

Cons: "Just give me a final price with a seat and a carry on!! Rip off!"

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

Pros: "New airplane"
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"

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."

Cons: "Delay after delay without much updating"

Cons: "Food"

Cons: "3 HR unknown delay"

Pros: "Not much It was just a flight"

Cons: "hard seats"

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

Cons: "Bad experience overall"

Cons: "Flight was delayed over an hour."

Cons: "Super late. No weather, not even a busy evening."

Pros: "We arrived"
Cons: "Two hour delay with no reason why which is a really big deal when you arrive at your destination at 1 in the morning and you need to be up to baptize a child at 8 the next morning."

Pros: "No problems"
Cons: "A little behind"

Pros: "Initially, the price but at the end it was painful"
Cons: "Three hours delays, round trip, both ways during one day"

Pros: "Super stoked about the seat I was in"

Pros: "It was fine.. no frills so no expectations"

Cons: "Spirit Airlines must make all their money on carry-on charges. Although I measured the dimension of my bag, it was slightly outside of fitting in their metal box at check-in, which cost over $50 when it still for in overhead no issues."

Pros: "Everything was fine, except flight was very late."
Cons: "Very late. No good reason given."

Cons: "I think charging for water is absurd."

Pros: "Watching people argue with spirit staff! Kept me entertained for my 2 hour delay..."
Cons: "How rude and unapologetic the spirit staff was. It was their only instinct in response to their lack of knowledge to the situation."

Cons: "My laptop was stolen out of my bag that I checked."

Pros: "I guess I should be happy that I am still alive. Other than not killing me, I can't say one good thing about Spirit."
Cons: "They screwed up my reservation on the way over and charged me to correct it, then they cancelled my flight back. The next flight they offered was the next day - no offer of a hotel or anything."

Pros: "Everything is at an extra cost. From snacks to luggage to picking your seat."

Pros: "The flight was on time"
Cons: "Charging for carry on luggage. Tiny seats and uncomfortable"

Pros: "Nothing except the price"
Cons: "Delayed boarding"

Cons: "Sitting at gate for 30 min unable to exit plane. Nightmare"

Pros: "nothing"
Cons: "Flight was delayed, Woman had an intact male Pit bull as a service dog ( therapy dog). The dog acted up 3 times in waiting area I do not know why they would let that dog in the cabin?"

Pros: "The option to have the first row with more comfort. The crew was nice."
Cons: "I'm upset that my bag came back broken. I've checked my bag several times with American and this never happened. Needless to say; this is my first and last time. It only takes one bad experience to lose a customer."

Pros: "Although the plane was delayed, the staff did want they could to get us to our destination as quick as they could."
Cons: "Delayed flight, which was fine but didn't update passengers as to why until we boarded plane. I didn't appreciate that as a customer. Questionable if I'll be a return customer in the future."

Pros: "Nothing"
Cons: "I arrive 45min before my flight took off and they said I arrived too late to make the flight. Then they tried to make me pay 160 dollars for one checked bag and 2 carry on bags since they charged a purse as a carry on."

Cons: "Delayed 2 hrs"

Pros: "The flight attendants."
Cons: "The delayed flight time and I had to check in luggage when I've done carry on with it before."

Pros: "We didn't realize there is a separate baggage charge. Ugh!"

Cons: "My flight was canceled right before I was leaving for the airport and no accommodations were made for me on another flight. I missed my entire trip because of this. I will never book with Spirit again."

Cons: "We were delayed for about three hours but there were no announcements or screens displaying that information. There was no indication that we were even at the correct gate. People had to walk up one at a time and ask to confirm what was happening and that we were all at the correct gate. Two hours after our flight was supposed to take off, there was finally an announcement letting us know that there was a delay and our gate would be changed so we needed to move out of the way so another flight could use the gate, but not to too far because they didn't know when or where our flight would be leaving from. It was chaotic and disorganized for no reason. I understand that delays happen but the lack of communication was unacceptable."

Pros: "Price"

Pros: "Nothing"
Cons: "When it came to payment- they said they wont accept cash. Wasted 30 minutes , getting a cash card. Next thing Lo, missed the flight. Very poor customer care or support."

Pros: "Comfy seats"
Cons: "Well of course pay for luggage but i didnt have any today"

Pros: "Crew was nice and on top of things."
Cons: "Seats were uncomfortable and at 5'7 not a lot of leg room."

Pros: "I liked the large airplane. We were all 3 seated together even though we didn't pay for seating. We weren't in the back. The seats were comfortable."

Pros: "Decent enough flight but they sure nickel and dime you"

Pros: "Return trip went smoothly"

Pros: "the price the fact that many lights cancelled to Chicago and you didn't"
Cons: "the delays that they would not announce until 5 min before boarding, on BOTocccasions. \I had to be getttinggg ready for work by the time I got home. such a bummer. wish hey were more honest about delays."

Pros: "We made it to our destination and back."
Cons: "No free water available Flight attendant couldn't remember any of their lines, 'among passengers nervous Extremely bumpy landing Janky, loud tiny plane Late both coming and going"

Pros: "The crew was friendly and they operated very efficiently."
Cons: "We already had a hefty layover in Chicago. Then our flight was delayed...and again...and again. An extra hour and a half was added to our almost 5 hour layover. I only got an explanation once I asked. And - nothing was offered in reparation."

Pros: "Flight was on time"
Cons: "Seats were extremely small and uncomfortable; also, Spirit is known for extra charges for everything (including assigned seats) so when you book a cheap flight make sure you know what you're in for. Actual cost is usually at least $50 more unless you travel with one change of clothes."

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."

Cons: "Bags can't weigh over 40 lbs. Everywhere else is 50 lbs. $100 for carrying on a bag at the gate is outlandish. Very rude staff"

Pros: "NOTHING"
Cons: "Everything with spirit is terrible. The trick prices (you think it's cheap??? Not if you want a seat, a bag, a drink, to breathe!!), the terrifying folding chair seats, the horrible leg room, the worst service. Now I remember why I NEVER should EVER fly spirit."

Cons: "Check in counter was EXTREMELY RUDE. Asked no more than ten seconds after they had told us to have a good day where to leave our checked baggage and the woman snapped and said she was busy... Sorry, you were just unclear the first time."

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

Pros: "Planes were new and clean."
Cons: "Airport was disorganized. Check in was long and a mess at 8:30 in the evening. Long lines. Staff not helpful. No checkin kiosk to get bag tag. Probably will not fly Spirit again."

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: "Everyone working was nice and helpful."
Cons: "Having a delay with the airline every time I fly."

Cons: "It was cancelled without warning or explination."

Pros: "Friendly on plane"
Cons: "Crowded gate"

Cons: "This flight was cancelled 2 hours before flight time and the staff was very unhelpful in re-routing me and my family. We were stuck in O'hare all day. I will never fly Spirit again."

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

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