Pros: "Short flight"
Cons: "Flight attendant was not willing to go above and beyond as he stated he would. My husband asked for a coke and the flight attendant told him he could only get water."

Pros: "Another safe flight. Crew was very attentive."

Cons: "Flight cancelled due to weather that was never bad but on the potential of bad weather. Had to scramble so my 18 year old son was not stranded overnight in a strange place and Delta does not help. Only rebooked a flight itinerary for the next day for a 4 hour flight with connections on a 1 hour direct flight. Spent an hour on line to figure out what to do. #neverdelta"

Pros: "Nothing"
Cons: "Plane delayed 4 times for a total of 4 hours"

Pros: "On time departure/arrival despite weather in Atlanta. Always a fan of free messaging and choice of snacks."
Cons: "Delta needs to invest in their gate area at ORD. Understand it’s not a hub but it’s a key business/leisure destination. The MD-80s are ok for a short hop but over 1 hour unless you’re in Comfort+, it’s tight."

Pros: "Snacks, cleanliness and crew"
Cons: "N/A"

Cons: "From the begging they changed the flights for something totally different. It was a 14 hour trip. Awful"

Pros: "Nothing"
Cons: "They take them forever to find me another fly ,make miss my other fly, my work my time and my sleep"

Pros: "It was a normal flight as well expected."

Pros: "I was with my friend"
Cons: "Delayed 12+ hours"

Pros: "We had a 2 1/2 delay due to mechanical issues but the crews, flight and ground, did a great job. Thanks."

Pros: "Staff were friendly and boarding was and getting off was easy because flight was super empty. Timeliness was appreciated too."
Cons: "Seats don't recline far enough."

Pros: "I was given a complimentary upgrade."

Pros: "The crew and pilot were absolutely amazing."
Cons: "This is my 3rd delta flight in a row that has been delayed. I understand these things happen, just extremely frustrating."

Cons: "It takes time and worries to find the air train and Aeroflot registration."

Pros: "My flight was great. Boarding was easy and the seats were comfortable."

Pros: "The service was amazing , the staff was honestly friendly and nice"

Pros: "Great service, nice agent friendly"

Pros: "Very friendly and professional gate agent and flight attendant"

Cons: "I was unable to fly at all due to a spelling error on my ticket. The airline refused to alter the ticket. Worst experience of my life, ruined my Christmas"

Pros: "The crew was friendly, relaxed, made everything seem like a breeze"

Pros: "Very nice flight and attentive staff. Enjoyed the view of NYC as we flew up the East River, then looped over Nassau County to approach LGA."
Cons: "The male flight attendant who handed out the complimentary drinks and snacks acted a bit strangely. I was very thirsty, and I asked him if I could keep the rest of the can of soda. He neither said yes nor no, but rather completely ignored what I said and just poured my drink and moved on. I was a mildly annoyed, but figured maybe it was policy and he was shy and didn't want to debate the matter. When he took care of the older couple behind us, however, things got really strange. He asked them whether they wanted pretzels or peanuts, but they misheard him and asked for a ginger ale. I happened to know that he did have ginger ale, since my wife had just gotten one, but rather than just pouring the old folks a drink, he repeated himself. "Peanuts or pretzels?" They misheard again and asked him whether he had a diet ginger ale. Again, rather than just pour them the drink, he repeated himself. "Peanuts or pretzels?" This went round and round a few more times -- like a poorly designed computer UI that refuses to accept anything except the correct input -- before the old couple finally figured out the disconnect and picked their snacks before their drinks. Very weird."

Pros: "Nothing"
Cons: "Cancelled my flight because I lost one of the arms"

Cons: "Layover"

Pros: "Short flight"
Cons: "Too cold Not friendly boarding agent"

Pros: "N/A"
Cons: "2.5 hour delay for no apparent reason at first (supposed mechanical issues with plane) and then waited on plane at gate for a missing pilot who never got picked up from his airport and got stuck in Chicago traffic trying to get to O'Hare. Eventually had to take pilot from another flight before leaving at 8:45 when flight was scheduled for 6:00am."

Pros: "I could be wrong, but the seats were very comfortable (for a plane) and I felt my knees weren't as close to the seat in front of me than other airlines. So that's a plus."

Cons: "Had a death in the family and no one would help me get back home"

Pros: "Seats were comfortable. Snacks!!! Nice flight crew."
Cons: "I liked everything."

Pros: "The Gogo Inflight wifi and entertainment did not work for even a minute. I choose flights based on their amenities and this one had offered full WIFI service which swayed me to choose to fly with Delta. I'm not sure who is to blame about this issue but I'm pretty frustrated that it was completely dysfunctional."

Pros: "Comfortable flight, ample leg room, and the chairs were pretty plush. Comfort+ is pretty nice"
Cons: "On my first flight they forgot to turn the wifi on. I have unlim data but obviously can't use while in air; no big though."

Pros: "The movie I watched was pleasant, although I had trouble hearing it because of the situation described below."
Cons: "There was a family seated behind us with several crying, loud children. We were miserable. Even my headphones with a Mozart sonata cranked up to loud did little to mask the noise. Probably not Dela'a fault, but the crew did nothing to mitigate the problem."

Cons: "Plane was sat broken at gate and needed part to be flown in. 150 minutes delayed. Not acceptable."

Pros: "flight attendants were great."
Cons: "not enough leg room and space. The business class should be at the minimum for economy."

Pros: "I missed my flight for the first time and I was having a complete meltdown at the check in desk until the sweetest agent said "oh no worries sweetheart, let's find you another flight back home"... It seems so simple but with the morning I had, this simple act had me in tears! The kindness and patience she showed me was amazing and definitely the reason I will always fly Delta to any and every destination they are able to take me! <3"

Pros: "No fee to get on an earlier flught"
Cons: "When I tried to rebook online this flight was not an option"

Cons: "I am a 5'3" 125# woman who, unfortunately, had a middle seat assignment. The passenger to my right, on the aisle, weighed approximately 375# and took up 1/3 of my seat. The arm was not able to go down comfortably, and when it did it was not usable . The passenger on my left, window seat, was probably 6'7" and had to sit with a man spread in order to fit. I could not move and was extremely uncomfortable. The plane was overbooked so I was unable to move. Therefore, worst flight ever. Plus, I paid for a full seat and was only able to occupy half of it."

Pros: "The crew was polite and friendly"
Cons: "My second plane had sooo much moisture coming from the cooling system it looked like the passengers were getting gased and I kept getting wet from water condensation falling on me in a window seat as I tried to sleep from having such an early flight to begin with only to be told it's delayed 3 hrs without explanation."

Pros: "Good seats."

Pros: "Free drinks in Comfort+"

Cons: "See above description"

Pros: "Flight attendants were great."
Cons: "Movie and TV selection is not great for an international flight."

Pros: "The in-flight service was good."

Pros: "Comfort with entertainment."
Cons: "No food options at all."

Pros: "Nothing"
Cons: "Poor hospitality by alaska airline staff, especially by MrPavel at gate H4, 01nov2016, prior boarding around 0730am"

Pros: "Delta's free in-flight wi-fi for entertainment (movies, tv, music) on your own device is a big plus. Not so easy to find (there's sparse information in their magazine or seat-back brochure), but once you find it there's a wealth of options."

Pros: "Small plane. Very good service. Did not suffer through the crazy multi level boarding calls that some airlines have. No super secret airline clubs that board first. Flying into the Marine terminal is the best part of the trip."
Cons: "The wifi didn't seem to work at all on the plane."

Pros: "Excellent"

Cons: "Flight did not leave on time. Weather conditions were not a factor."

Pros: "Everything was great. Easy boarding great comfortable seating and friendly efficient stewardship"

Cons: "Boarding was a little chaotic. Could have been more organized."

Pros: "staff was amazing, entertainment great, dasani sparkling lime water tasty, very clean and reasonably comfortable"
Cons: "the breakfast was made of 90% sugar - this was very disappointing."

Pros: "Everything was on time!"

Pros: "I got the vegetarian meal I asked for."
Cons: "Flight was delayed, because of the boarding process with immigration"

Pros: "This flight left about 90 minutes late again due to weather issues. The crew was excellent which made this long flight enjoyable."

Pros: "Staff extremely friendly and helpful"
Cons: "Old plane with no individual tv screens!!! Didn't know these planes still existed!"

Pros: "Extra blanket and pillow. Empty seat to sleep in. Fairly clean interior for the most part."

Pros: "Flight attendants were nice"
Cons: "The seats were incredibly uncomfortable. There was no leg room and 122 of the space below the seat in front of me was taken up by a metal box attached to the seat. I couldn't put both feet under the seat in front of me. The food was bad tasting and overly processed. We were fed a lean cuisine. The entertainment was from mounted tv's in the aisle. At this point, all planes crossing the ocean should have individual tvs for a customer to watch. They had this 15 years ago, how do they not have it now."

Pros: "All good! Nice staff. Easy travel."

Pros: "The crew was very efficient and friendly while handling everyone. Flight was smooth, food was good. I went to the wrong terminal and did not know that the advertised finair flight was actually American Airlines, the AA ticket counter attendant went all out to make sure I made it to the gate. All this with less than an hour before departure."
Cons: "I went to the wrong terminal, the email ticket had finair in large print and in smaller print indicated American. Luckily I was able to literally run and make my flight. Would be better to more clearly indicate actual airline."

Cons: "Small seats, no wifi, no chargers, terrible entertainment."

Pros: "Once we got on the plane, everything was pretty standard"
Cons: "Flight was delayed 5 hours."

Pros: "The staff were fine and boarding went relatively smoothly."
Cons: "The plane was dated and small. There were no individual screens for entertainment. I've flown internationally with American before and felt this specific experience was worse."

Cons: "This made the check in process extremely frustrating and confusing. Traveling with my elderly dad who had to squeeze between two large men for 7 hours because people who actually booked the airline got priority seating. We had to pay an extra $500 to upgrade to comfortable seats. Not pleased w Kayak."

Pros: "I did not have a seat! Waiting for people to give up their seats!"

Cons: "Poor entertainment, wifi option. Overhead lighting was on entire flight. AA flight attendants were over it. A bad experience"

Cons: "Old plane with no plug-ins and outdated media."

Pros: "finally made it to our destination"
Cons: "our flight was delayed 3 hours, they finally changed planes, and the one we took for a trans-Atlantic flight was cramped, poor service on the plane, all-in-all an uncomfortable flight - I've had much better on other carriers, and won't be likely to use American Airlines again :("

Pros: "Not much to like, plus we were late"
Cons: "Seats were uncomfortable, no in-seat or personalized entertainment."

Pros: "Staff on the plane were nice."
Cons: "5 hour delay, fear of cancellation ruining a trip planned for years, not feeling we were told what was happening, series of delays extending decision time, unappetizing sandwiches during delay."

Pros: "An agent found me a window seat for the Chicago-Barcelona leg of the trip with extra leg room. That was amazing. Also, the lost luggage assistant for American Airlines was super helpful and nice. Also, the 787 (I think that was the Chicago-Barcelona craft) was a very enjoyable airplane. It was super smooth. It had high tech windows that adjusted the amount or type of light that could filter through the windows depending on the settings."
Cons: "When I arrived in Barcelona my Bag went missing. It showed up an two hours after my flight landed."

Pros: "Nice head rest (although it did not stay bent at angle, so could actually rest against it)."
Cons: "Think it is ridiculous that I had to pay so much to select a seat ahead of time, and it was just a regular seat. I can understand for extra legroom or exit row, but for a regular seat, that is ridiculous. Then there was a fee to change priority boarding, so I could ensure I was able to have my carry-on with me, instead of risk having it go underneath."

Pros: "Free alcohol and good passenger friends and friendly service."
Cons: "No outlets for phones"

Pros: "Food on time. Good Food. Good Entertainment like watching movies. Top priority for Diabetes or any other patients."
Cons: "Little guidelines for new comers especially while changing the flights."

Pros: "Flight was on time. Smooth flight."
Cons: "In flight entertainment was below expectations"

Pros: "The American Air crew was great very attentive and they pass out free drinks"
Cons: "The 787 is tight and when the fight is 7 plus hours it tends to ware on you"

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."

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: "Crew was excellent but it was literally the most uncomfortable plane ride I have ever been. There was even an empty seat in the middle and I couldn't sleep at all. The seats were super shOrr and the headrests sucked"

Cons: "My flight was actually processed under American Airlines. Oddly, the confirmation email stated it was Finnair."

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: "On time"
Cons: "Cramped seats. Entertainment system outdated"

Pros: "Efficient boarding. Plane clean. Seats lean back far but that being said the individual in front of you ends up in your lap."
Cons: "As night went on a couple of the flight attendants in the premium cabin seats with standard legroom appeared grumpy and short with patrons. No gluten free options. In flight entertainment and reading lights not working for my dad or I. A long flight for that to be out."

Cons: "Plane was too old, flight attendants were rude"

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: "No complaints."

Cons: "Boarding seemed extremely unorganized. Crew skipped group 2 when calling groups to board, resulting in a mad rush."

Cons: "Due to two flight delays, I traveled an additional 24 hours, on top of my 20 hour original flight. Albuquerque Airline staff were rude, dismissive, incompetent, and each individual I spoke with gave me wildly differing information. The two delays (leading to approximately 48 hours of travel) would have been stressful enough, but the callous, ignorant and unprofessional attitudes of American Airlines staff (and staff in general at Chicago O'Hare Airport) really disappointed me. This was even more striking compared with the professional service I received from British Airways (from whom I purchased the tickets). I was ashamed that my country could lag so far behind in terms of basic customer service and problem solving."

Cons: "Requested for wheelchair assistance but none provided?!!"

Pros: "Seats had enough room. Inhad been worred they'd be too close since iwas the middle of a 5 person row."
Cons: "The boarding was terirble. We were over and hr late take off and it was very hot boarding and it took a long time. Also the air was so dry i got a nose bleed."

Pros: "I was served breakfast and lunch/dinner"
Cons: "Trying to sleep in an airport is near impossible"

Pros: "Timing and transit time was excellent"

Pros: "Everything."
Cons: "Nothing."

Cons: "Food was horribe and no dedicated tv per seat"

Cons: "They cancelled the flight and put me to fly the next day"

Cons: "overcharges"

Pros: "My favorite part of the flight was our on time departure! :-)"
Cons: "I don't care for the configuration of the Airbus 320...it's rather difficult to adjust the overhead light and air, compared to the placement on a Boeing 737."

Pros: "The flight was late and barely made the connecting flight. In the end, my luggage arrived damaged."

Pros: "Once the flights took off, everything was just great."
Cons: "The boarding process was awful. There are zones, but they are all boarded simultaneously. What's the point of paying to board early if you don't get the chance. Then, I had to check my bag because the boarding order was a mess. One flight attendant tried to force me to put my bag overhead when I told her I could fit it under the seat. She stressed me out unnecessarily."

Pros: "Friendly"
Cons: "Delayed more..."

Pros: "Flight delayed- missed connection. No easy way to get Home to Vermont. Flew to Boston and rented car!"

Pros: "The crew was very polite at every moment"
Cons: "I really liked everything"

Pros: "Helpful gate staff"
Cons: "Frozen croissant for breakfast. Non-functioning entertainment centre. Seats recline too much. Passenger in front leant back as far as he could (without courtesy of request or apology), making my flight most uncomfortable."

Cons: "Flight switched, old plane operated by Privelage Style, 0 entertainment and poor service throughout the 7 + hours from Chicago, flight an hour delayed as well"

Pros: "The econmy class seat was just fine for a cross atlantic flight from Chicago to Paris and I am almost 60! Good entertainment and service. Seats were comfortable. Language was not a barrier. Good value because it was non-stop and a no hassle plane changing circus! Thanks."
Cons: "Food was airline style and could have used some fresh fruits and bakery goods. But overall it was very passable."

Cons: "Had to pay for movies and snacks."

Pros: "The crew and captain were amazing dealing with us during a terrible, late night delay. They constantly kept us updated about what was happening and were constantly walking around to ensure all of our needs were met."
Cons: "The plane was absolutely horrible. Two bathrooms and the in-flight entertainment did not work as well as most reading lights. A door sensor wasn't working correctly which cost us another hour of waiting for a technician to come and repair/reset the sensor."

Cons: "No help, and after hold of 45 min, representative hang up on me. I lost a ticket because of very bad customer service!"

Pros: "Nothing"
Cons: "Over 4 hours of delays including on plane then everyone was kicked off. We waited more and they cancelled the whole flight and everyone had to scramble to get on anything available. I lost 28 hours of my vacation. They put us in a scary hotel in Chicago. I received a $200 voucher for further flights that doesn't even cover the cost of my unrefundable expenses such as car, hotel and tickets that were lost on my vacation."

Cons: "small video monitor"

Pros: "Again- nothing"
Cons: "This flight was canceled for me! Why am I being asked how I would rate it?!"

Pros: "Didn't think my seat was too comfortable. Had to sit on my neck pillow. But flight was on time. Crew friendly."

Pros: "Nice crew"
Cons: "Horrible plane, old and not comfortable at all. Little entertainment to choose from and the technology on the plane was horrible. No healthy food options, won't fly United internationally again"

Pros: "That transportation was available in Chicago."
Cons: "No problems."

Pros: "Boa 're ding good"
Cons: "Lights on in plane all time american keeps lights dim so people rest"

Cons: "Gate attendant accused me of trying to get "free extra baggage" when I simply asked whether there would be gate-checking on this particular flight."

Pros: "Lufthansa fueron súper amables. Todo bien agradable. Buena comida."

Pros: "On time, courteous & caring flight attendant & desk staff. Unable to understand pilot or first officer's PA announcements...language & microphone issues. Airplane is severely cramped so flight was uncomfortable."
Cons: "See above"

Pros: "-Blue lighting and head space makes the plane feel more open. -Staff was patient considering the unfair backlash they were getting for the recent abuse of a United passenger. -Seats were well cushioned. -I arrived home to my family alive, unhurt, and safe."
Cons: "-2 hour delay (especially after I arrived 2 hours early) is unacceptable. -Overhead bins too low over our seats. We can't stand up straight at our seats making it very difficulty to get in and out of our seats. -Couldn't access entertainment on my Mac laptop. -Bathroom closets are too small. Floors in the bathroom were consistently wet because the sink is too small for people to wash their hands. -Two bathrooms for the majority of the passengers on the plane is just not enough and you know it. It's pretty uncivilized. It creates a line at the back of the plane covering at least 5 rows. Then, your aisles are too narrow. So we have to rub our bodies up against each other to let people squeeze through. -I think you guys could do better than one tiny bag of pretzel mix for a 5 hour flight. -Let's get upper management flying in economy across the country and see what they would change."

Pros: "All services where very good from check in to arrival In L.A."
Cons: "There wasn't anything I didn't like."

Pros: "The older planes of United Airlines could use some remodeling. The entertainment system with controls in the middle of the arm rest where the elbow rests is such a bad idea, didn't even bother with this crappy unintuitive system. It was annoying and flashy with bright advertisements or something popping up on a night time flight just sooooooo annoying, turning it off was not intuitive and had to ask the flight attendants how to turn it off during their very busy work of handing out packages with five miniature pretzels and drinks to the passengers, was happy to get a whole cab of juice to myself though."

Cons: "We had to check our hand luggage and be charged EUR120.00 We should have been aware of this before we obtained the boarding pass..."

Pros: "Polite crew"
Cons: "Food."

Pros: "Had fun watching free movies on my device, although the connection didn't work for the first leg. The plane was new/upgraded, a ton of legroom on my second leg Airbus."

Pros: "For the basic economy seat there was plenty of room and the staff was excellent. Honestly the best domestic flight I've taken in a long time."

Pros: "Go"

Pros: "Service"
Cons: "Total disaster due to some snow, excessive delays"

Pros: "temperature was right not blanket needed"
Cons: "they ignore me never offer me a drink and I was thirsty"

Pros: "Everything went pretty well minus the delayed flight from the start"
Cons: "Some older woman yelling at a teenager for "pushing her in the back of her seat" while in flight"

Cons: "This flight was delayed around 3 hours."

Cons: "Had to check a bag I've carried on several other times."

Cons: "Lack of leg room, no TVs, no free wifi"

Cons: "Flight was delayed because one of the flight attendance was late showing up."

Pros: "Flight was on-time."
Cons: "Flight to Washington Dulles was boarding at the same time through the same door as flight to Washington National. Why would you schedule it this way? Plane cabin lighting was mostly burned out so very difficult to see while getting on the plane. Window appeared to be caulked on, exit door handle cover in row behind was falling off causing concern for passenger in exit row. Plane was generally shabby and run down. Flight attendant was reading all announcements which did not inspire confidence in her training. Small regional jet, so seats and leg room were terrible. Made us wait outside in the cold for our hand luggage that was too large for tiny overhead bins while we watched baggage handlers drop several carry-ons from the conveyor belt onto the ground. In addition they lost one of our two bags."

Cons: "The flight was over one hour late departing ORD. We had approximately 15 minutes to make our connection at IAD. While I understand that the delay happened because the copilot was late because of a fender bender, I believe the delay could have been much shorter. Since they had telephone contact with the crew member we could have been boarded before he was on the plane and departed sooner. Also no reasonable explanation was given for the delay other than a crew member was not there."

Cons: "Flight took off early while I was still aboard the inbound connector. I was supposed to be mollified with a boarding pass for 9 hours later and a hotel room. Gee thanks."

Pros: "Crew was responsive"
Cons: "I didn't like the extra 2 hour lay over in Ethiopia."

Cons: "I was informed today that one of my checked bags was picked up by another customer who eventually realized it was not her bag. She brought it back to the airport and refused to turn over the bag until the airport compensated her. (How this happened I have no idea because I stood right by the entrance of the baggage claim and never saw the bag come out). The customer refused to return the bag until the police became involved at which point she agreed to write a note confirmed she did not steal anything. The bag then needs to be sent to me in 2 days and I'll have to verify myself that indeed nothing was taken from the bag. I'm very concerned how this individual came to be in possession of my bag considering, again, I stood right at the entrance of the baggage claim conveyor belt from the time it started to when it ended. As a result, this experience really made me feel frustrated and violated."

Cons: "They knew we were on our way to the connection. They told us to run, we did. We were not aloud on the plane. Caused 10 hours of flight delays and cancelled flights because they could not wait 2 minutes.... Horrible experience."

Pros: "Good crew"
Cons: "Bumpy air"

Pros: "It's hard to understand why the flight attendants cannot be consistently polite when communicating with customers."
Cons: "Sour attitude of one of the flight attendants. The age of attendants doesn't bother me, just when they are jaded and surly, especially on a transPacific flight."

Pros: "The in flight staff was nice"
Cons: "The young lady at check in at Chicago was very rude and unhelpful. She only checked our bags to Brussels not clear to Dakar. Finally when we got to Brussels a helpful attendant was able to make some phone calls and he got out bags rerouted on to Dakar."

Pros: "The amenities aboard the plane were great."
Cons: "United is a terribly run airline. My flight was constantly delayed, then canceled at the last minute. The airline did nothing to compensate customers who were stranded in Chicago."

Pros: "The appointment as shape"
Cons: "Small aircraft and noisily to much"

Pros: "On time flight"
Cons: "Single beverage service on a 4 hr flight? You've got to be kidding. Luggage didn't make it. "WiFi" experience is a dud - too slow to do amy meaningful work"

Pros: "nothing"
Cons: "4+ hour delay, could have told us in Philly did NOTHING to compensate, not even a free drink taxied out to the runway to only sit for another half hour overall just terrible temperature went from Very warm to cold & back to warm.... could not adjust it"

Pros: "Plane was fairly new."
Cons: "Get some of the passengers to behave like intelligent creatures"

Pros: "We liked how organized and fast they were in every sense."
Cons: "One part we didn't like was one sarcastic/rude flight attendant. Other than that it was a great experience, it was my first time using frontier and I would use them again it was safe great solid airline."

Pros: "Easy"
Cons: "Shared my row with 500lb people and though two rows ahead of me had two empty seats I couldn't move to be comfortable. This beast of a woman couldn't put her arm rest down and therefore her body was smashing mine the whole time. It was disgusting."

Pros: "Crew was nice."
Cons: "Seats very uncomfortable."

Pros: "friendly attitude"
Cons: "$85 for two checked bags, many little issues along the way but got there safely"

Pros: "Fare, boarding, seat selection, ease of purchase."
Cons: "On my first leg of my round trip flight free refreshments were offered. On my return flight they were not and was told everything beside water only was available for purchase. It also seemed a bit unsafe for during the course of the short 2:15 hr flight between Chicago and Austin for the Pilots to leave the cockpit with the only things standing between someone rushing the cockpit when the door is opened are a drink cart and an older female flight attendant."

Cons: "THE most uncomfortable seats ever!! The seat bottom has been reduced in size by half - the edge hits mid-thigh - and all cushioning has been removed - like sitting on a folding chair, but less comfortable! And the pricing: I paid as much to bring my luggage with me as I did for my "seat". And to top it off, it was a red-eye flight and the crew were yacking the whole time. I will NEVER fly frontier again."

Pros: "Bag charged"

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 fact that Reclining seats are a upgrade is unexceptable . The price online to check in your bags change during a check in. I was charged more than what your website state. The check-in reservation is was rude and unwilling to correct a computer glitch . She stated that your software had no ability to override a mistake."

Pros: "Not much. Very amateur service"
Cons: "To pay $40 for a carry on bag is being a thief. The seat in the plane do not recline... comfort is a thing of the past!"

Pros: "Little."
Cons: "Worst flight of my entire life."

Pros: "absolutely nothing."
Cons: "cheap seats, dirty plane, garbage in the front pockets. Nickle and dime you to death on everything!"

Cons: "Departure delay was too long on board"

Pros: "The seats were comfortable enough. The departure was 40 min late, but the plane eventually landed according to the original schedule, which was nice. The price was very good, even with adding 40$ for too big carry-on."
Cons: "The attendants were talking way too much, making different announcements and explanations almost non-stop. They also organized some kind of reshuffling of people inside the plane due to the need to ... rebalance the aircraft. Never saw it at any other airline."

Pros: "Nice crew"
Cons: "They nickel and dime you for every little thing! You want to bring any luggage? Too bad it costs $35 or $60 per bag. You want to pick your seat? Too bad it's $11+. You want any food or drink on the plane? Too bad it's expensive."

Cons: "Email notification of a 3 hour flight delay 2 hours before flight but I was already on my way to the airport. Then the flight gets cancelled but no email notification was sent and the screen wasn't updated at the gate (the whole time I was there). If I hadn't come back to the gate during the long delay and asked a fellow passenger why they were in line, I wouldn't have known it was cancelled for a long time. The employees at the gate were helpful in refunding our tickets, etc. but overall, not happy with my experience with Frontier Airlines."

Cons: "Behind, plane troubles, and very uncomfortable seats. Not worth the money"

Cons: "there were too many delays and the situation was handled poorly. I do not plan to fly Frontier again in the future."

Pros: "wait times kept changing and got totally ridiculous. my uber cost me twice as much and i was delayed 4 hours. never flying with you ever again."

Cons: "All the extra expenses for seats, baggage, ect."

Pros: "Nothing"
Cons: "Everything"

Pros: "Not much, the time it takes to get to the places is short which is nice."
Cons: "Delayed flight, only $15 dollars of food too late and not acceptable at restaurants, too long of a delayed flight."

Pros: "This was the first time I have flown Frontier. Even with a checked bag fee ($30 each way), my total fare was still less than half of what it would have been for competitors the same week. The planes were clean, flights were on time, and the crew were extremely friendly and helpful!"
Cons: "There wasn't anything not to like! The experience was seriously better than I imagined it would be."

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

Cons: "Worst seats in any plane I have EVER been on (and I travel ALL the time). Those steel seats with 0 cushion have resulted in me having the worst back pain and being on bed rest for the past 3 days on severe pain medication with no signs of improvement. I will never fly Frontier again."

Cons: "to expensive to cary on a bag."

Pros: "The tate"
Cons: "Paying for bags"

Pros: "The whole trip is pretty bad. It is delayed for 5 hours. And no free water on the airplane. You basically has to pay for everything: food, checking luggage, and carryon bags. No entertainment at all. The flight tickets are not cheaper anyway."

Pros: "There wasn't any in flight entertainment and I didn't order food, so that's why my rating is neutral. Our flight back was 30 min early, so that was great."

Pros: "Easy boarding easy check in"
Cons: "Nothing that bad, chairs are maybe a bit thin but not terribly uncomfortable"

Cons: "Lots of screaming children, but I had to fly to Orlando."

Pros: "On time"
Cons: "All the hidden costs"

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."

Horrible, horrible experience."

Pros: "Pay extra for another airlines. Frontier is uncomfortable and you have to pay for everything after the ticket. You only end up saving minimal amounts."

Pros: "Frontier airines was great. We got a ridiculously cheap flight so to pay $30 for a carry on was no problem. We knew all the fees up front so we planned accordingly and packed light. Staff was friendly and organized. Flight got in early."

Cons: "The flight was fine.. We didn't know that we have to pay a luggage fee for a carry on for $45.. I was surprised when they told us to pay since carry on so far in other flights were free.. The seats weren't comfortable since it doesn't recline. This plane really is only good for probably a one hour flight not 4 hours because you can't even relaxed and reclined your seat.. All food you have to pay including water.. I will never fly frontier ever again..."

Pros: "Original ticket price was cheaper than any other, and flight time options were great for an early flight out or late flight in, etc."
Cons: "Cheap and cheap. O'hare has an awful set-up for bag check and security for frontier/spirit/virgin/other cheap airlines together. You wait to print, then wait to check, then wait to drop your own bags (with zero instruction or customer service or signage), then wait for security. They hate for EVERYTHING: just to check in for your flight and pick a seat. $11-17-37 to sit together. Each. And then for bags. $35 to check and $60 to carry on (makes no sense) even when checking in online early. And even more cost to have both checked and carry on. And seats don't recline, that costs more. And have a 4inch by 5 inch-ish tray table. And EVERYTHING costs money onboard from WATER to Pepsi to snacks. It cost an extra $92 each way for two of us to check in and check one small bag. My back hurts and I will ALWAYS pay a bit more for another airline."

Pros: "Nothing"
Cons: "Everything"

Pros: "Really good experience"

Pros: "The price for the trip was great. I thought the boarding was efficient and the flight crew pleasant. Check in at the airport was very easy although the automatic machines were non functing."
Cons: "Long pre security screening lines. The seating is rather cramped."

Pros: "I got where I wanted to go for a reasonable price."
Cons: "I did not calculate for the extra fee for a carry-on. I'm always disappointed when I don't get a complementary beverage and snack. Sad but worth the savings."

Pros: "Flights were cheap."
Cons: "You end up paying an additional $30-35 to check a bag or carry on-board, you also end up paying $15-20 to reserve a seat. In addition, they won't accept your checked-in baggage if you're not at the airport 45 min before boarding to drop it off. They made me re-book my flight out of Chicago for the next day and charged me $99. I was only 5 min late to drop my bag off, and because of bad traffic. The airline has no empathy, they seem to be only concerned with charging you at every opportunity they get. I will never fly frontier again."

Cons: "inflight everything requires payment."

Cons: "45 dollars for each carry on . Not pleased to pay 90 extra dollars. Never flying Frontier again"

Cons: "While booking I was unaware frontier airlines charged for carry on luggage and didn't participate in TSA pre check. In addition to paying $45 more for the ticket than advertised and having to use normal security, the plane was so cramped the guy behind me hit me in the head. Finally there was a persistent foul smell in the plane. It was a rough 4hrs 30 min. I would recommend spending more and flying southwest or United."

Cons: "The price of the trip did not include a seat, nor baggage, this was unclear and I felt misled. The seating is extremely uncomfortable. Checking in online was terrible, the website was hard to navigate, the prices were inconsistent (I was checking on my phone and computer at the same time and getting different rates for seats). I felt the communication was poor. I did not feel safe. I will not choose this Airline again."

Pros: "Inexpensive flight. Friendly but no nonsense crew."
Cons: "Why do they seat front rows first? You would think that would block people from getting in."

Cons: "Nothing"

Pros: "What more could you ask for we were on time. The pilot saved 20 minutes in the air. Staff was polite and attentive. The plane was just renovated."
