Cons: "The flight attendants were fantastic!"

Cons: "We PAID $30/each to check 2 bags, both ways, so $120 total. Then at the gate, BOTH WAYS, Delta Gate Reps allowed people to check bags for FREE, & pick up at bag claim, just like WE PAID TO DO. NO MORE DELTA FOR US!"

Cons: "Not delayed"

Pros: "this is the airline"

Pros: "You know what you are getting with Delta"
Cons: "The economy seats were really tiny, this made the flight fairly uncomfortable"

Pros: "The crew was very friendly. The plane was very quiet (except for noisy crying babies)."
Cons: "Unless you can afford the higher priced "comfort class" or first class seats, the seating is very, very cramped on Delta's 757s. It's a good thing the flight was only 5+ hours (but that's not long enough to get any decent amount of sleep on this flight scheduled as a redeye)."

Cons: "Better allergy aware food."

Pros: "Friendly crew"
Cons: "We reserved exit row seats and when they changed the plane they gave our exit row seats to others."

Pros: "N/a"
Cons: "The crew members were very rude and they called me an IDIOT!! Yes they did because the forced me to check my carry on bag and i didnt want they are racists"

Pros: "I was in Comfort+ so there was a bit more leg room than standard economy"
Cons: "Even with Comfort+ things are tight."

Pros: "room and services"
Cons: "can't think of anything"

Pros: "We left early"

Cons: "they let someone get off the plane and it delayed the flight an hour and a half which caused me to miss my connecting flight. I now have to sit for a 5 hour layover"

Pros: "wonderfu crew... very helpul`"
Cons: ".."

Pros: "The selection of movies was great."
Cons: "The food. No herbal or decaf tea. No decaf coffee. The regular coffee and regular tea was awful; I like strong coffee and tea but on the plane it was terrible. The was not a vegan option for dinner. I thought the pilot announced complimentary beverages; soft drinks, coffee, tea & alcohol. Perhaps I was mistaken or maybe he was. I like the seats (reclining back with the seat bottom moving forward) except the seat bottom is entirely too hard and was bad for my back. The hot towels are a welcome touch. The ride was smooth, the pilots did a very good job."

Pros: "Everything went great. Flight left a little late but was fine and only arrived a little late. I like the side wings on head rests really help."
Cons: "Seats are always hard on long flights."

Cons: "After we boarded and were already sitting in our sits the stewardess came and removed our bags from the overhead compartment for another person with a larger bag! We ended up storing our bags under the sits in-front. The way it was done it was rude and with no consideration for our comfort."

Pros: "Got to London on-time (early, actually) and safely. The in flight meal was okay. The leg room in comfort plus was great, the mobile app was awesome, and the staff (check-in, gate, cabin and flight deck) were professional and friendly all around."
Cons: "The leg room was great, but as a broad-shouldered guy, the width of the seat was miserable. Unfortunately, the Delta 767 doesn't offer any upgrade for a wider seat beyond Delta One, and my employer won't spring for that. Too bad there isn't a premium economy option. Also, the entertainment unit in the seat next to mine malfunctioned, which you wouldn't think would impact me that much except that because it was "seeing" touches randomly throughout the flight, the screen would turn on, off, brighter, dimmer, play random stuff, and just generally be as annoying as possible to everyone nearby throughout an overnight flight."

Pros: "Easy and quick"
Cons: "No complaints"

Pros: "on time, good food, good films enough space to sleep in economy."
Cons: "the stewardess only went up one side of the plane offering eye shades and when i asked for one she seemed really miffed."

Pros: "Great service throughout. Friendly attendants and easy boarding/deboarding processes. Would fly international with them again in a heart beat."

Pros: "We didn’t order food and there was no online entertainment"

Pros: "Delta flights run one time and their fleet seems newer than most with comfortable seating. Having free movies in the seat back ahead of you is a big plus with a good selection of movies. Snacks are good and crew is always friendly and accommodating. We fly almost exclusively with Delta for the aforementioned reasons."
Cons: "Boarding is a hassle no matter the airline with few exceptions. You would think someone could figure and efficient method to get people on the planes. I suppose it could be the public that is the problem. Not a problem with Delta they run a good airline."

Pros: "Nice people. Very helpful."
Cons: "LOST MY BAG IN BOSTON BEFORE EVEN TAKING OFF!!!! Did not make it, and then won't deliver it when it makes it to Kathmandu! This is most distressing."

Pros: "Everything else"

Pros: "The overall flight was good."

Cons: "No power to charge"

Cons: "Jet airways sucks"

Pros: "The only positive of this leg is that it was less infuriating than the flight from RDU to Boston"
Cons: "Delta's partnership with Go Jet seriously compromises the legacy carrier's reputation. I am a Delta fan - although flexible enough to use other choices when necessary. I will no longer fly a Go Jet operated leg when other choices are available. For my trips to Boston, that means Jet Blue. Sorry Delta. I'll see you back on a true Delta route."

Pros: "Great crew and passengers"

Pros: "Wonderful flight attendants"
Cons: "nothing"

Pros: "Entertainment offered, USB charging options."
Cons: "Too much food offered."

Pros: "Within Europe KLM short flights are very good. They give you a snack and something to drink without charge."
Cons: "Seats,are a little tight but like most other airlines."

Pros: "Nothing."
Cons: "Reservation. Checkin. Seating. Flight."

Pros: "It was a really good flight minor turbulence towards the end. Flight was on time, smooth flight. NO tvs on this one."
Cons: "I wish they had more snacks like JetBlue but all was fine. TVs on every plane would be nice."

Cons: "The process of checking was very poor. One line was serving all of the Delta flights. Agents were very slow. Even when they started to serve my flight with priority still no impruvment. The agent who served me was so lost that he could not find the page with my picture and name in my passport!!!"

Pros: "Not much to like since the flight was canceled."
Cons: "Flight was canceled. The system tried to automatically rebook us but gave us a new itinerary from our original departure point, apparently un aware that we had already left. So, we were stuck in Atlanta airport with no good way to our final destination. Instead of waiting for 22 hours for the next available flight, or driving for 7 hours from Atlanta to Cincinnati, we had to fly into another city and drive to Cincinnati from there AT OUR OWN EXPENSE. It was a rebooking nightmare."

Pros: "Boarding was efficient and easy. For the first time on any airline, the crew was over-the-top friendly and my special meal request was excellent."

Pros: "Rebooked to Atlanta because of a delay."
Cons: "Delta notifications and Kayak notifications were giving me conflicting information, however once I arrived at the Houston airport a Delta representative clarified my issues."

Pros: "It's what I didn't like....as a Sky Miles member I should get a free bag. Small aircraft for a FL trip."

Pros: "I liked nothing, because the flight was 4hrs late and had 20 on standby."
Cons: "4hrs late, 20 on standby, missed connection, had to travel a day later and spent 14hrs in the airport."

Cons: "I'm just glad that we got to the airport 2 1/2 hours early because we needed it. We had to check a dog so we had to go through the special needs line, they had 2 out of 20 of ticket lines open. My wife also needs a wheelchair and after 45 minutes of standing in line, I spoke to one of the idiots that are supposed to be there to help and he went and got a wheelchair which I had to push my wife in the wheelchair through the zig zag line with 2 large suit cases and a dog. It took us an hour and a half to get tickets and then they called for someone to push the wheelchair and we where told to wait for them there. We waited for 10 minutes for someone to come but no one came so I started pushing her towards the Sercurity check line and finally someone came to push her and he stayed on his phone the entire time. When my wife got to the point where she needed to walk through the metal detector she was having a little trouble getting out of the chair so they told her to just stay in the chair and they would push her through in the wheelchair. When she got through, they almost strip searched her and patted her down like she was a criminal. That took another 25 minutes!!! They the guy pushed her to our gate and insisted on taking the chair back with him, so 5 minutes later they asked if it was anyone who needed assistance getting on the plane. I went up and told them that my wife needed a chair to get on the plane so they had to call and get another chair which took another 10 minutes and finally we got on the plane. It took us 2 hours and 15 minutes to get a ticket and go through Sercurity!!!! Very very very unprofessional!!!"

Pros: "The customer service was great. Due to it being winter flights are expected to be delayed, Delta kept on sending me updates via text so there was no surprises when I arrived at the airport."

Cons: "make me sleep in the airport unexceptedly"

Pros: "Really liked the Airbus A320 (or whatever we were riding on). Plane, crew and experience were fantastic."

Pros: "When we were landing!!!!"
Cons: "To crowded, seats to to!!! close need personal space not everyone baths!!##!!"

Pros: "Why did my seat assignment have to be done at gate. I booked early and had picked a seat on eac flight."

Pros: "All flights were on time. Captain of plane rides were awesome at their jobs. Flight attendants were courteous and friendly."

Pros: "The staff was pleasant and very caring. I traveled with my sister who was in a wheel chair due to he ability to walk long distance and they were just outstanding. And I want to Praise Delta for their understanding and most caring and assistance in assisting me on changing of my return flight due to my husband had a stroke on Thanksgiving Day. I was able to leave out on Friday (11-27-2014) with no problem."

Pros: "I didn’t like anything at all"
Cons: "They have to add electronic devices or charge plug on it"

Pros: "Nothing"
Cons: "They canceled the flight"

Pros: "Crew on board are great."
Cons: "American keeps canceling and changing schedules. They cancelled flight section and took it out of my itinerary. Then took over 3 calls and 2 hours on hold to fix."

Pros: "Amazing Crew"

Cons: "The flight from Boston was extremely delayed,but miraculasly, the boarding to conecting FinnAir flight 6, took extra 10 minutes, which gave me a chance not to catch it. Though, me and the AA rep., had to cross-run about a mile up and down the escalators at terminal 8 , my baggage was left behind and did not make a transfer to FinnAir 6. At final destination I was asked to file a lost baggage claim. If not the initial flight from Logan, everything should go smoother."

Pros: "Bos to Rome via jfk. Both flights easy in all ways. Grrat first class seat one first flight and quite good bus class on second. New Flagship Lounge a real plus."

Pros: "Ease of boarding with the group numbers"

Pros: "Best landing I’ve experienced recently!"

Cons: "Too cold"

Cons: "Entertainment system went down toward the beginning of the flight. The crew seemed irritable, but that was probably because people were upset about the entertainment system. We had to listen to a loooong speech about their credit card. I, personally, don’t like sales pitches over the intercom in the middle of a flight. Had the movies been working, it would’ve paused during the long speech. Not cool at all!"

Pros: "No hassle of changing terminals in JFK, no bagagge claim, AA check-in-this time, was a "good luck"....Connection in Helsinki, very quik!"
Cons: "Finnair flight AY06 are old aircrafts. Every other in-seat monitor was out of order, flight attendants could not do much. That created mess for passengers, trying to move their seats to the ones with working monitors....."

Pros: "Professionalism and all time smile of the crew"
Cons: "That there is not TV in the plane"

Cons: "The plane was dirty, the window had a leak, the TV was too far away and the sound system to watch the movie was broken. When the plane is in that poor of a condition, it's time to replace it. F."

Pros: "The flight crew was professional, friendly and competent. They served the dinner as early in the flight as possible."
Cons: "This was a plane with central screens along the aisle, and the airline chose to broadcast a sci-fi action movie with almost constant flashing blue light, and violent action scenes. This was first of all a movie that many people, including me, would never choose to watch, but since it was on the aisle screens there was no getting away from it. It was also unsuitable for children, even without sound. But mainly, I object to the showing of any film in that situation - only aisle screens available, and on a night flight where most of the passengers are trying to sleep. I was awakened several times by the flashing lights. Other things: one of the bathrooms was not very clean, and the plane felt like the usual cattlecar, with just 3 seats on each side of the aisle, which is unusual and unpleasant for a transatlantic flight."

Pros: "The boarding was fast, the flight was faster than expected too, crew was very efficient and friendly."
Cons: "Space between seats too small, breakfast not good, too far inside the plane... Not so happy of the company rules : whatever you want to change, it will cost you. I suppose it's the way to keep flights cheap, but it's not fair to pay if when you arrive first, you have to pay to change for another seat... One free luggage of 23 kg when you cross the Atlantic is not enough..."

Cons: "None"

Pros: "Cabin was clean. Flight attendants were courteous."
Cons: "Their snacks were merely a cookie which was okay, but not what I would have wanted."

Pros: "Good service from crew members"
Cons: "The flight was delayed for 2 hours"

Cons: "This is our honeymoon! Every single blessed thing you sent said British Airways, but it was really American. Ended up at wrong terminal. Staff uncaring, plane cramped, seat reservation not honored. The worst. You will be getting a letter on your deceptive practices and I am going to bury you on social media. Kevin Howard"

Pros: "Everything was smooth and organized. The flight even arrived early. Friendly crew and comfortable seats with extra leg room (but these were too expensive). Food was quite good for airline fare."
Cons: "Fee for more legroom."

Pros: "The flight was very smooth and the crew was so friendly!"
Cons: "It was an older plane and it felt a bit cramped."

Pros: "Wine"
Cons: "No tv's for such a long flight. One tv on the ceiling every so often does not qualify for entertainment.. flight was delayed for 3 hours. Never American Airlines again"

Cons: "No wifi or any video"

Pros: "We arrived safe."
Cons: "The plane had been on the ground for 6 hours prior boarding time, yet we leave until 1 hour late. Waited for the food to be loaded and then waited for paperwork to be signed. Really?"

Cons: "American Airlines made me check my carry-on luggage, despite there being many open overhead compartments visible on the plane."

Pros: "The flight was on time and the crew are nice with the people"
Cons: "Too crowded not able to take my other luggage on board."

Cons: "I was supposed to be there right now, but I'm still waiting in Chicago for my connecting flight to Dayton that was delayed."

Cons: "Jetway should not be backed up all the way to the counter. Stop calling so many groups for boarding without knowing that no one is actually getting onboard. Force subsequent groups to step aside until called."

Cons: "I purchased extra legroom but got less - front row.Between two very large elderly gentlemen. No overhead storage either. Miserable and long flight."

Pros: "All good - with every aspect of the trip."

Cons: "4 hours of no air conditioning in a middle seat..."

Pros: "Good crew, very pleasant and professional."
Cons: "The three and a half hour delay was not great, but since it was due to weather issues in Chicago, certainly not the airlines fault. However, the communication about the delay was terrible. There was nobody and the gate, so we were relying on automated notifications from the airline. They kept pushing it later by 30 - 45 minutes at a time. We could have gone to the airport much later but just didn't know that."

Pros: "Loved the people, very friendly and accommodating. I sat in first class and felt very comfortable."
Cons: "I think needing your own device for entertainment is awful then having to pay rental fees, even if you're in first class."

Pros: "Crew was nice including those helping with boarding."
Cons: "Difficult to recline chair. Limited snack options. Landing was a bit rough."

Pros: "The plane was not full"
Cons: "Booked Brittish Air, got American. Plane delayed, no wifi, TV screen could not be seen from seat. No control of TV. Plane seats old & uncomfortable. Paid a premium price for a sub par experience."

Pros: "Plane wasn't full"
Cons: "We booked on British Air, but got American Airlines. Something I didn't realize. I don't like Amercan Airlines! No internet, no tv. Only overhead tv too far away to see from my seat and no choices Old plane"

Pros: "No turbulence Efficient"

Pros: "I made it to NY somehow"
Cons: "Everything. I have 2 roller bags I carry on to every flight I have ever taken and they charged me $25 per bag to check because it was a "snug" fit into their dimension box. Also gave no snacks and only half can refreshments, no entertainment."

Pros: "The great atendance and on time bording"
Cons: "There is no More options of free food included with the ticket fly"

Pros: "The flight crew was pleasant and the flight was smooth and on-time (both departure and landing)."
Cons: "The seats are *tiny* and cramped. The aisle is so narrow that you can't roll a standard sized rolling carry-on suitcase because you're constantly catching on the seats. The 'entertainment' is the old-style 'everyone watches the same thing on tiny monitors' as opposed to seatback monitors."

Pros: "Got there in one piece"
Cons: "Left late. Ran out of food before all were served. Cabin staff were weary and more attentive to each other than the passengers. With us packed in like sardines,American maintains it's reputation as the Greyhound of the air. Next time Jet Blue."

Pros: "Friendly staff at the gate, also the crew as goodl"
Cons: "Don't need 2.5 hours delay to start my vacation. We finally checked in at our hotel at 01:00am....."

Cons: "Flight was cancelled due to weather and AA was very unhelpful finding accommodations, even finding our luggage."

Pros: "Quick and easy! Nothing major"
Cons: "Nothing."

Pros: "Good crew"
Cons: "Hardly any food options, don't accept cash for food or drinks, over all uncomfortable flight."

Pros: "had onboard in seat entertainment. Mostly TV shows but not bad."
Cons: "Center seat, group 3 boarding, poor seat spacing in coach."

Cons: "The flight landed about 30 minutes early. We spent one hour on the tarmac waiting for a gate, resulting in us being late .. compromising many with tight connections."

Pros: "30 minutes early in Dallas,"
Cons: "Cabin where I sat was way too warm"

Cons: "Changed equipment and my aisle seat went to middle seat with no advance notice"

Cons: "Everything about it was terrible. So late we nearly missed a legal AA contection. No USB or WIFI as promised. Rude staff."

Cons: "Serving something substantial to eat would be nice."

Pros: "The flight was smooth and the crew was nice."
Cons: "Everything was good."

Cons: "There HAS to be a different snack choice than just salted pretzels, right? Not everyone is a fan of those. And although it may have been a last-minute issue, learning that there was no WiFi as we ascended 10,000’ into the air was quite disappointing. No techie around to troubleshoot that while we were boarding? Otherwise, the flight was uneventful and the crew was pleasant enough."

Cons: "The food was terrible."

Pros: "Full flight, we got on smoothly and took off on time. The plane was clean and the pilots during abbouncekents were easy to understand and funny."
Cons: "I had to wait over 1.5 hours to use the bathroom because of the food and drink carts. The flight attendant would not let me use first clsss and told me I had to wait. That was way to long to make someone wait."

Pros: "Typical intercontinental flight in coach. Plenty of movies to watch, bin space and comfortable enough seats."
Cons: "I have a severe food allergy and despite requesting and confirming my special meal multiple times I was only offered a banana for the entire trip."

Cons: "Honestly, I am not a big fan of United right now and their airline policies. The flight was delayed for a hour. But at least I wasn't dragged off the plane or stuck in 95 degree weather for 5 hours."

Cons: "The bathrooms were dirty out of toilet paper. The food was mediocre at best. The delight wasn't delayed hours and no one informed us about the status at any point in time. Overall I did not like airchina and I would not choose them again if"

Pros: "Nothing at all"
Cons: "How they wouldn't even hand out a cup of water to anyone....."

Pros: ".."
Cons: "Flights was delayed and connection was unable to be made. My younger brother is now im limbo in newark nj and is not getting much help at all. Very dissapointed in united. He may have to spend the night in the airport they said. Smh"

Pros: "Nothing"
Cons: "Our plane departed on time, 6:05 AM. About 6:40 A E turned back towards Boston. There was a problem with the wing. It got repaired. We deplaned. And waited. And waited. Then we needed fuel to be removed. And we waited. And waited. Then we got back on board, got to the runway, and the RIGHT ENGINE didn't start. So they tried to repair it, couldn't (didn't want to fly on that old, broken plane anyway at this point), and we had our flight canceled. All told, I spent 10+ hours at Logan Airport. It was an absolute disaster."

Pros: "nothing"
Cons: "they have the worst customer service."

Pros: "delayed"

Cons: "Our flight home we couldn't land in Chicago due to storms and diverted to Madison. Sat on Tarmac 2 hours and some passengers from Madison allowed to end journey there. We had to wait for that approval and again had to wait for their luggage to be removed from the plane. My opinion is let them disembark but not the luggage. It was too long to be in that plane"

Pros: "It was a comfy plane ride."
Cons: "I liked everything."

Pros: "Crew was helpful, professional & kind."
Cons: "Flight was delayed due to air traffic control issues so I only had 40 min layover to get to my next gate. Also when we arrived we were on the ground for a long time before we could pull up to gate to unload. I have a 3 yr old & 5 yr old & had to run to make it. We made it but luggage didn't. My first luggage was delivered quickly, the 2nd luggage arrived 3 days after we arrived home."

Pros: "refund"
Cons: "Hour delay that made me miss my connecting flight. Customer service agent, Theresa, at the United gate was more interested in checking her cell phone text messages & handing out $10 food vouchers than the long of people who have conflicts with connecting flights or missing events in the destination they were flying to. Every minute lost could prevent customers from obtaining another immediate or comparable flight to their destination. Customer service agent sent those who were going to have problems with their connecting flights to the United Airlines service desk, of which, there were no customer service agents at any of the four available stations. I waited 10 minutes for an agent & no one arrived. When I went back to the original line I was standing in, I was forced to go to the back of the line rather than the place I was originally standing. Therefore I waited in line an additional 20-30 minutes. Once I was served they did not have any more seats available on direct flights to Melbourne. They wanted me to fly to NY, then Sydney & then Melbourne. Additionally the customer service agent did not seem confident this flight was not going to have any hiccups. Worst of all, I had been planning this trip for months & it was ruined by United Airlines."

Cons: "Unreliable wifi."

Pros: "Crew friendliness"
Cons: "Boarding was a mess with an adjacent gate exiting at the time of boarding creating a melee of people crossing queues. You have a carry-on baggage policy - stick to it. I wasn't carrying any roll-ons or large items but many of my fellow passengers were carrying multiple items in the hope of either getting them on or having them checked for free. Complete shambles with later boarders running up and down the aisle trying to fit their carry-ons into overhead lockers. Solution: Enforce one item only; Apply free checked items at the gate early. Apply a fee for items that don't fit and were not offered up for checking."

Pros: "Boarding was consistent and timely"
Cons: "Older, worn interior, especially if seats are pushed back"

Pros: "The flight attendant was excellent. Much better than most of your other ones."

Pros: "Getting off the plane"
Cons: "Bathrooms weren't working, huge lines in aisle, lackluster service. Overhead bins were full by Group 3. late takeoff."

Pros: "Did get last seat in business class!"
Cons: "The seat assigned online not valid because of change of equipment. Did result in upgrade to business. Very happy outcome."

Pros: "Broading was seamless"

Pros: "Very satisfied."

Pros: "I liked how the flight attendants treat people in this flight. Thank you all."
Cons: "I didn't like how long the flight was, but that is not up to anyone to decide. I liked my stayed in the airplane."

Pros: "Crew was very nice."
Cons: "Plane aisle was a tight squeeze with carry on bag plus seats were very close together, and I'm a small person at 5'1". Otherwise flight was good."

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

Pros: "The airplane itself was great but the rest was not so good. United tries to sell you everything and the seating was miserable. We are back to JetBlue at first opportunity."

Pros: "Quality plane Clean"
Cons: "Seats too close together. My shoulders were squeezed against my neighbors"

Pros: "Upgrades available and ahead of schedule !!"

Pros: "This was the best leg of the trip."
Cons: "That we where heading to Chicago further from our end destination."

Pros: "Comfortable chairs"
Cons: "There are no TV's and there are no snacks"

Cons: "It was alarming how little leg room there was. I'm 5'5" and average weight and my legs were pressed against the seat in front of me. Also there were no free snacks for a 5.5 hour flight, which is kind of tacky."

Pros: "Old plane, no plugs, no in flight movie, didn't even offer complimentary snacks. Had to pay $10 for a snack box on a 6 hr flight. Completety unacceptable that on such a long trip, they offered no complimentary food, no movie, and although they offered "entertainment" on personal devices, you needed to download the united app to watch on your personal device. But wait, NO PLUGS??. So basically your phone / ipad battery will die 1/2 way through the flight and then you will have no way to use your phone after you arrive at your destination. Way to go united. Your corp execs should be ashamed for making you the worst airline with the highest prices."

Cons: "United has stripped away every element of customer service. We had to tag our own checked luggage. They were unable to even try to seat me together with my toddler child who was seated alone. (Age 3). We scanned our own boarding passes to board. As I boarded with bags and 2 children, 4 flight attendants stood watching and said "make sure you don't hit anyone with your purse as you walk down the aisle". No one offered the slightest help. The flight attendant would not take my trash because she said a diaper had to be disposed of in the restroom. (We were not allowed to stand bc of turbulence.) When I played white noise to soothe my crying lap child, the flight attendant told me I would have to use headphones (which is impossible on an infant.) I won't fly United again."

Pros: "nothing"
Cons: "t was delayed without informing me i stay in airport 6hours"

Pros: "It was clean and the stewardesses were nice."
Cons: "I curbside checked my bag, and when I got to Cincinnati, it never got off the plane. I had to ask several times for them to go back into the plane and look again. They finally did and found it. But it was just a nightmare."

Pros: "Still waiting to get there.....canceled flight.....next option 6 days after my original date"

Cons: "The arm rests didn't got back, only affected row 37 (our row)"

Pros: "The flight was on time and left on time."
Cons: "seats are to close together."

Pros: "Very nice crew"
Cons: "Wish there was some free entertainment"

Pros: "Good flight"

Pros: "4 hours delay???? Are you serious? Compensate my time and all I lost"

Pros: "Very unforgettable flight and very late on all flights. 4 out of 4 flights late!"

Pros: "I arrived safely."
Cons: "Plane was delayed 2 hours in ERW United counter workers were terse or rude Inefficient operation Waited 1 hr. 45 minutes for bags to appear at CVG Not flying United again"

Cons: "Pay for wifi it's free everywhere! !!! Restaurants bars..airports...cities...???"

Pros: "The fact that they eventually got us to the destination"
Cons: "Broken first plane. Delayd all other planes. Poor communication. Rude staff..."

Pros: "Had a single seat on the small jet"
Cons: "No offer of so much as a peanut or pretzel for almost an 2 hour flight"

Pros: "The flight attendants were friendly"
Cons: "The tvs in the head rest pretty much did what they wanted"

Cons: "5+ hour delay the only compensation was a voucher for a cup of coffee"

Pros: "NA"
Cons: "Na"

Cons: "I did not like it took an ENTIRE hour for the passengers and MYSELF to get our bags off of baggage claim. Our flight landed @ 11:38 pm we did NOT get till an hour later! I will be contacting corporate!"

Pros: "The flight was smooth and arrived early."
Cons: "The seats were extremely uncomfortable. After 30 minutes, it felt like you were sitting on ply-wood. Seats did not recline at all. No leg room. Flight attendants stayed to themselves during the flight and seem to do the absolute minimum. Luggage retrieval took forever."

Pros: "I liked how both outgoing and returning flight were early/on time! Crew was very friendly. Plane clean. Will definitely fly Frontier in the future."
Cons: "Of course, paying for carry on is absolutely ridiculous. I don't really drink pop while on plane, BUT $2.99 per can of pop is robbery. I can't even tell you how greedy that is."

Pros: "Not much"
Cons: "Flight delay. Missed my flight and attendant at gate 16d was very rude when she returned. I could have got on plane If she had been at her station."

Pros: "Crew"
Cons: "The flight was delayed 2 hours, which I didn't get the text message until after I had dropped the rental car and was waiting in line to check my luggage. so many hidden fees.... would have been cheaper to go with delta."

Pros: "Everyone was friendly, courteous, and professional."
Cons: "No warning of carry-on charges."

Pros: "It was cheap if you don't check any bags or bring an extra carry on."
Cons: "The check in process was brutal. Line went from the back wall of check in all the way to the opening near security at MCO. Understaffed, staffed in the wrong places, NO staff helping with kiosks, and we almost missed out flight because it took so long."

Cons: "Canceled the flight for no reason."

Pros: "Everything went smoothly and on time"
Cons: "Having flown multiple times on Frontier, I find it odd that you never hear anything from the cockpit. Like: Welcome passengers. estimated time in flight, crusing altitude, estimated arrival time, weather at destination, starting decent, etc. Of course, as an ex-military and corporate aviation pilot, the more I know the more comfortable and connected I feel."

Cons: "Clean the seats off!"

Cons: "I had to wait over an hour to get my bag at the San Francisco airport"

Pros: "On both flights the crew was extremely friendly, fun and accommodating. Both flights took off on time and our flight home landed 45 minutes early!"
Cons: "The seats are not the most comfortable. You do have to watch out for all the added fees: checked bags, carryon bags, seats (you actually have to pay separately for your seat), food, drinks, etc.. When comparing costs - you need to add everything up. In our case, Frontier was still around $150 less than Delta. But don't be fooled by the low fare when you still have to buy a seat and pay for baggage."

Cons: "Plane comfort is average."

Pros: "Price was good for a direct flight"
Cons: "Pretty much everything else. I checked in online - where they clearly state that there will be a bag drop for prepaid checked luggage. There was not. Instead there were three people behind the counter (only two were actually taking anyone from the long line) - who seemed completely confused. They at least knew that the gate had changed, but they didn't know where it had been changed to. I found it. It then proceeded to change 3 more times. The final change was not announced, we all just followed another passenger who had seen the change listed on the airport departure screen. The final gate was "39" a door in a hallway that opened up onto a tarmac. We waited there about 30 minutes (after the scheduled boarding time) before the door opened. They had no scanner for passes, so the attendant had to write things down on paper when we showed him our passes!! The actual cabin is tight, but that's to be expected. What wasn't expected was the random turning off and on of overhead lights throughout the (red-eye) flight. It was like a torture technique. To round out this great experience, the flight attendant instructed us to de-board the plane in order. Row 1 (left side) then row 1 (right), etc. This clearly pissed off many passengers who had no carry-on luggage and could have just walked off while those with stuff in overheads waited. When I finally got to exit the plane, I heard a guy somewhere behind me say "f-you" to the crew as they gave us the traditional "have a good day". We all felt the same, just didn't say so."

Cons: "It was almost 3 hours dleyed and nobody explain why, and we walk to airplan from outside it was terable."

Pros: "The employees were nice."
Cons: "The line at the airport to drop off my luggage (which was prepaid) was crazy long as most people had not prepaid and some were trying to pay with cash (which Frontier does not accept). Even tho I had my boarding pass printed and luggage paid for I waited almost an hour in this line - and I arrived 2 hours 1/2 early. After arriving in Cincinnati the luggage took at least 40 minutes to arrive at the pick up point. On my outward bound trip to Orlando the luggage took over an hour to arrive at the luggage carousel. It seems that Frontier does not have a good rapport with the baggage handlers at the airports."

Pros: "I liked the initial price of the flight. But it only goes downhill from there."
Cons: "You have to pay for your seat, anywhere from $6-36, no complimentary drinks or snacks on a 2.5 hour flight, very little legroom on a fairly large plane, a 9:15am flight took off at 10:30am... all in all a bad experience. The crew was friendly and boarding was easy, but a $35 checked bag, and a $35 carry on bag fee made this flight cost significantly more tha from competative airlines. Very disappointed and I don't think I'll be flying Frontier again."

Pros: "This was my first flight in nearly 25 years and it was my moms and son's first flight ever. Enjoyable experience and we definitely hope to do it again soon!"
Cons: "Better leg room would be my only suggestion."

Pros: "They nervously switched us to a new plane when they couldn't fix the first one."
Cons: "No food, not even a magazine to read on the 4 hour flight. Both of my flights were delayed without any prior warning, so I was sat in the airport for hours waiting for them to extent the delay (which they did several times on my way to my destination). Avoiding Fronier in the future."

Pros: "Crew was good, flight on time"
Cons: "Frontier and spirit use the same Airbus aiprlane with the worst seats in the industry. My back hurt before the airplane was pushed back from the gate."

Cons: "Seats did not recline and were very uncomfortable. Couldn't believe you had to buy your drinks. No snacks. By the time that I paid all the a'lacart it cost me more than a flight with Delta or Southwest. Will not be flying Frontier again."

Pros: "Good price."
Cons: "Baggage claim at CVG was soooooooooo slow. My bag took over an hour to finally arrive at the claim."

Pros: "I really liked the tickets prices and the boarding was fairly smooth."
Cons: "I understand there is a trade off for the lower price fair but $40 a one way for your bag is a bit much. The crew largely were not very engaged with the passanger. I all but had to rais my hand and shout out to the attendant to take my order - the passanger next to me had to say something to the attendant on my behalf. I get people at one point or another have an off day - but it was bad a Ly the same on the way on second leg f the trip"

Pros: "The staff"
Cons: "The plane, the five-hour delay."

Pros: "I found the seats to be an acceptable level of comfort. I'm not a skinny person but I didn't feel any more squeezed in than on any other airline."
Cons: "There was a one hour delay on my flight out and the pilot apologized for this during his announcements. Ended up at my destination about 45 minutes later than scheduled but this did not cause any problems for me."

Pros: "Most everything else was oK."
Cons: "As I said, the seats don't recline, and are shy on padding. Very uncomfortable. Might be ok for a short flight, but, NOT 3-4 hours. Won't do that again!"

Pros: "New plane (A321)! Everything was very clean!! My tickets were still under $275 round trip with baggage fees. Very inexpensive!"
Cons: "Tray table was very small, seats didn't lean back."

Pros: "The non stop flight is the only way to go. That part was nice."
Cons: "Trying to prepay my baggage was a nightmare. I never, repeat I never had so much trouble navigating a flight option in my life. I spent an hour before leaving Cincinnati and before leaving Ft. Myers. I was forced to pay $40 for one bag each. Online baggage fee was $25. I would like to be reimbursed the difference please. If this doesn't do it, I will write to the airline. Sincerely, Peter j Vlasic"

Pros: "For the price it's all good! Food I would have rated " N/A". Worse thing is comfort; seats are not comfortable and quarters are tight. But I will continue to fly Frontier b/c of savings."

Pros: "comfortable seating,,,more leg room than most. very professional and friendly crew."
Cons: "advertised as low cost but if any luggage needed and would like a snack and drink, there is no savings and may cost more."

Pros: "Absolutely nothing."
Cons: "My connecting flight left without me, which left me stranded at the Denver airport and Frontier was not able to fly me home because they has no flights left to Cincinnati. Not an ideal experience for someone traveling alone for the first time."

Pros: "clean plane, on time"
Cons: "Small uncomfortable seats. Small unusable trays. No complementary services. Overpriced baggage fees. Minimal carry-on allowance. not my favorite airline – except for the cute animals painted on the planes."

Pros: "Check in staff and flight crew were seamless. If you are looking for the most pared down flight available, and aren't bringing any luggage, then the flight was reasonable and often the cheapest available."
Cons: "You will be charged for carry on bags and drinks didn't the flight. The seats are uncomfortable and don't recline and, are minimally padded. The website says paying for luggage online prior to arriving is cheaper than if you pay at the airport"

Pros: "Liked the meal and next flight coupons."

Pros: "NOTHING!"
Cons: "The worst experience in all my years of flying. Carry-on fees, unexplained carrier imposed fees, seat fees, bad service, no complimentary beverage service. Spent nearly the same amount in fees as I did on the ticket. Will never fly this airlines again or recommend. It's clear why frontier was on the worst airlines list next to spirit."

Pros: "Outstanding customer service by Susie (from Barbados) in DFW. They went out of their way to accommodate us. She even sung happy bday for mom's birthday. I have a special needs brother and they let him board early to give him extra time. Above and beyond, we absolutely love this airline. They are the megabus of the sky. Sign up for their frequent flyer program. Tickets are insanely cheap and economical, you can fly for $15 if you do it right by joining the yearly program ($50 annual) and responding to the emails. We booked 5 adults CVG to DFW 6 days out for $123 a piece when Delta and other competitors wanted $500 to $600 dollars. Pilots have a great sense of humor, flight attendants were super attentive and helpful. Be careful on the bag restrictions, my advice is travel light with carryon. The rest is pay for play but you can jet-set for stupid cheap and still receive superb service. I can't say enough great things about this airline. We are booking at least 7 to 8 more flights with them for the next few months for the price of 2 tickets with any other airline. Rivals Jet Blue or Southwest level of experience for fun but absolutely crushes all other airlines in value. Best flight experience ever!!!!!!"
Cons: "Almost nothing disliked about this airline. Read the bag criteria rules closely. They do distinguish between personal item and a minor bag fee for carryon. Don't really have any complaints at all as this has been my best travel experience with an airline ever. Without a doubt my new go to airline for travel in CONUS"

Cons: "The fee for a carry-on bag if you had a purse as well. The fee for a soda. I had to buy a seat? Never again the flight attendants were burnt out and ill tempered. No you won't be seeing me again."

Pros: "We didn't get food and the flight we were on didn't have any entertainment. You need a N/A choice. The price was great!"

Pros: "Crew"
Cons: "Handicap should only sit in the front of the plane. First to board. First off the plane. Accident almost happened with the rushing of people and elderly man could have been knocked over."

Pros: "Left on time arrived on time baggage came very quickly and stewardesses were very friendly! Great experience!"

Pros: "Kayak made it easy for me to book my trip and everything went as planned. Everything was perfect and i will definitely be using kayak again in the future."

Pros: "The straight non stop flight."
Cons: "There was only the one flight out to Cincinnati. There should always b more than one flight out with multiple flight times."

Pros: "Staff was very professional and kind."
Cons: "Tray "table" is a bit of a symantic stretch. It is the size of my hand, and it has no clasp to hold it, so children were whacking it up and down on both of my flights. Better to put some cupholder there then that so-called tray aka sound machine. Also, be sure to pay for baggage online wgen you book! No free carry-on! And if you pay on da of, you will pay MUCH more!"

Pros: "Plenty of room staff was amazing and most of all it WAS ON TIME !!"
Cons: "Nothing"

Pros: "I was looking for an affordable flight to go on a weekend visit and I found a great rate with Frontier. The flight was boarded and departed in time. The aircraft was large but the seats are small with little padding and little leg room. For a two hour flight and for the fare I got, this flight was what I needed; I wasn't looking for amenities or comfort so this met exactly my needs."
Cons: "It is necessary to check in 24 hrs before and if you forget there's an extra charge to check in at the airport."

Pros: "Felt like it was a safe flight"
Cons: "Seats are too close together and we did not want to pay more for another seat. They ask too much to sit at an exit seat"

Pros: "Leg room in the front was adequate ."
Cons: "Seats were a little uncomfortable ."

Cons: "Seats were small and uncomfortable...did not recline"
