Cons: "Such tiny seats."

Pros: "Crew was nice."
Cons: "Plane was very old (from the 90s?), cabin kept freezing all night. Now my husband's luggage has been lost and we are getting conflicting information on how to retrieve it."

Pros: "Comfortable flight except for limited leg room. Great movie selection."
Cons: "Poor leg room for tall people"

Pros: "Not using kayak"
Cons: "Kayak booked me the worst itinerary in the history of air travel!"

Pros: "Food was good. Staff was polite."
Cons: "Both flights were late leaving. Plus then we waited on board for a long time. Once on board and waiting, no explanation, no updates. No idea what was going on or why. An announcement would have helped a lot. Philky-Prg: Long delays with food , staff was slow on the Philly -Prg flight. Seemed like they didn't want to be there. No info from flight crew. Phily to Prg - Crappy old plane that should not be flying over seas anymore. Applies to both flights unless specified."

Pros: "The helpful steward"
Cons: "The bumpy ride"

Pros: "fairly comfortable, crew was helpful"
Cons: "Having to use my phone for entertainment, with no place to plug it in"

Cons: "I'm not sure where the problem was - whether with AA or Royal Jordanian, but my luggage did not make it to Amman with me. In fact, there was a whole group of passengers traveling on American from different US cities, switching to RJ in Chicago, whose luggage did not come on the flight to Amman. My advice: be sure to pack enough for a couple of days in your carryon - and don't accept an offer to check your carryon to its final destination!"

Cons: "We had five pieces of luggage lost during our flight from the U.S. to Spain. When we arrived in Madrid we were told that all five pieces had been located. When we went to pick them up the next day there were only four pieces at the airport. We were told the fifth suitcase would be delivered when it was located. It's ten days later and there's no sign of the luggage. It has taken multiple phone calls to get the information about the luggage correct. They assure me that they have everything correctly documented and then when I call back they haven't changed a thing. It has been a very frustrating process overall."

Pros: "Comfortable seats, good legroom."
Cons: "Not enough coffee for breakfast."

Pros: "Arrived 20 min early. Smooth flight."
Cons: "Didn’t have individual movie screens."

Pros: "Seats were comfortable enough"
Cons: "They force you to get to the airport really early."

Pros: "Food and entertainment were great"

Cons: "This was a BA flight on an American Airlines plane. Very small crowded and uncomfortable. My husband is 6'2" and barely fit in the seat."

Pros: "The crew was awesome."
Cons: "You guys lost our luggage!"

Pros: "Good connection"

Pros: "I like that American offers free movies thru their app but there was a glitch and I couldn't get it to work!"
Cons: "Couldn't get the entertainment app to work"

Cons: "Maintenance problems, late departures, uncomfortable airlines"

Pros: "The main crew person checking us in was very nice and attentive, tried to keep me posted on changes, and remained pleasant even though some were getting upset."
Cons: "flight was delayed, staff didn't update us so people were getting upset and irritable while waiting to hear. Then flight times changed without announcements, upsetting some."

Cons: "The flight was delayed 9 hours for mechanical issues and they were not able to do anything. Since booking with Kayak neither Alaska airlines or American Airlines would help in getting us an earlier flight and both airlines said they couldn't help after repeated calls. Won't be booking any American Airlines flights throug Kayak again."

Cons: "Delayed flight due to crew."

Pros: "There was nothing too bad other than I wasn't able to check in online bc our first leg of the flight was operated by American Airlines. But there wasn't anything that really stood out that would make me want to fly them again other than it was the best price."

Pros: "The crew was very helpful at each stop even though they weren't responsible for the disasters."
Cons: "Initially we thought we were flying with British Airways. We then had to do some digging to realize it was all out of American Airlines. Then we couldn't get proper boarding passes and luggage tags until one of the crew members spent a significant amount of time untangling each leg of our trip so they were in the proper order. We got delayed by 4 hours in Chicago and missed our connection in Manchester. We had another 5 hour wait there. By the time we got to Dublin, our bags didn't also arrive. After almost 24 hours of travel, we arrived but without all of our stuff."

Pros: "Easy flight, friendly crew."
Cons: "Girl next to me being sick the whole time"

Pros: "Flights attendants were super friendly and the plane was very clean"
Cons: "seats are uncomfortable"

Pros: "Excellent, friendly attention from flight attendants."

Pros: "They were on time"
Cons: "The A321 had the most cramped seating I've ever experienced. The video in the seat back didn't work properly going or coming back. Boarding was slow. I don't know why they don't load the rear seats first so you don't have to wait for everyone ahead to secure their carry-on luggage. If they didn't charge so much for checking a bag there wouldn't be so much carry-on baggage"

Pros: "Im still waiting to get on a plane..."
Cons: "Since TSA took so long I missed my flight by 5 minutes. Then I was put on standby. Ive been at the denver airport for 10 hours and the plane i was going to get on has mechanical problems so the flight is pushed back until 7am tomorrow. Ill have been at the denver airport for 26 hours and then i have to wait on standby again in Dallas. Who knows when I'll actually get home. American airlines is not even offeri6mg any vouchers or anything. Worst flight ever."

Pros: "El problema es que el vuelo estaba sobrevendido y han cerrado las puertas antes con lo cual me he quedado abajo sin pode abordar. En el aeropuerto de Denver habia solo dos personas en el securty check por lo cual la demora fue involuntaria en mi caso. Cuando estoy haciendo la fila para ingresar al avion (esyando en la misma cola antes de ingresar) me informanque no podre embarcar..(claro ya habia designado mi billete a otras personas. pesima atencion y pesimna experiencia con los empleados de ese vuelo. Denver a Miami"

Cons: "Late departure. Seats were double booked. Had to delay again to sort it out."

Pros: "I liked everything from the way they got everyone on the plane to getting everyone deplaned."
Cons: "I didn't have a problem with the airline. Just a couple of passengers."

Cons: "I had to leaves Denver early due to my granddaughter needing help. To sees switch returns my ticket it would cost me me $200.00 but it could get a retire ticket for that day for $40.00. Why couldn't that dollar amount come of my ticket . That was just crazy"

Pros: "My departing flight crew was very accommodating for my baby and I. They were very pleasant."
Cons: "I wasn't able to board first with my baby, so I had to try and walk through all the passengers with a baby, diaper bag and small carry on. It was a little difficult."

Cons: "I had a severe back injury in Denver and they were unable to move my flight up a day to get home and see a doctor. A good friend had to buy me a new flight with his airline miles so that I could get home to relive my pain. I'll never fly American again because of this complete lack of compassion and care for their customer."

Pros: "On time. Good crew and nicer flight."
Cons: "Actually no complaints."

Cons: "Small narrow seats"

Pros: "For the first time, ticket counter from the Denver American air assistant patiently review the my connecting flight when flights were delayed twice!"
Cons: "AA keep announcing they will be delayed hour at the time and with east coast time changes, I almost couldn’t make it to fly second connection flight. They should give us guide line to exchange the connecting flights."

Pros: "Friendly service"
Cons: "Snacks"

Pros: "The flight was fine"
Cons: "Both flights each way where delayed significantly"

Cons: "Flight was canceled going back to denver from Augusta. American did nothing to compensate me for their mechanics breaking. Had no place to sleep and no transportation as I return my rental. Poor customer service will never use American again!"

Pros: "Seat was comfortable, and my favorite on this aircraft - 3F on the MD80. Boarding was quick, and service was efficient once airborne."
Cons: "AA crews are skimping on pre-departure service, rarely offering PDBs (pre-departure beverages), or, when they do, half-assing it by putting water and OJ on a tray and making it clear nothing else is available as they did on this flight. It sets the expectations very low for the rest of the flight, and that's what happened."

Cons: "American delayed the flight 7 times before cancelling it. They then put me on a flight 7 hours after the initial departure time. That flight was delayed 7 times and then they cancelled it. I wasted 10 hours at the airport."

Pros: "how easy it was to purchase ticket on kayak."
Cons: "Being charged for my checked bag unexpectedly at check in."

Pros: "Space security manners"

Pros: "Seats were comfortab"
Cons: "The flight attendants, could have been a bit friendlier"

Pros: "Cool TV roomy seats , friendly staff."

Cons: "Delayed 2+ hours"

Pros: "Great flight crew"

Cons: "Boarding process makes no sense to the flying public and is just another money making deal for the airline."

Pros: "Nothing"
Cons: "Our flight was delayed which caused us to miss our international connection. Flight attendants did not care, did not attempt to get us out faster, or put on a different flight. Asked for an announcement to be made on board or to be moved to seats closer to the front so we could get off the plane quicker, did not happen. Offboarded and sprinted across the airport for our international connection and was notified by gate attendents that the gate closed five minutes ago and that they could not let us on the plane. Meanwhile, the plane sat there for an additional 30 minutes while it fueled and waited for release from air traffic control. There were six travelers total stuck there in San Fran at that gate, all of us begging to be let on the plane to Beijing, the last one for over 24 hours. Zero compassion from staff at the the airline gate. They did not care about us and did not care about leaving their travelers stranded. Our total travel was Denver to Bangkok, 26 hours of travel including layovers in San Fran and Beijing. In San Fran (after missing the gate connection), United rerouted us through Haiwaii and the customer service agent that did this reroute did not finish the reroute to our final destination. We got to Haiwaii and were stranded again, at the United service desk for four hours having to once again provide documentation of our initial travel plans to Bangkok, having them build a new itinerary to our final destination. Overall, 20 additional travel hours have been added to our itinerary, almost double our initial travel time. We have had to call and cancel pre-arranged bookings in Thailand as we are now missing two full days off our trip. I am absolutely disappointed and heart broken as I write this still stuck in the Beijing airport waiting another six hours to connect to Bangkok. My fiancé and I were traveling to Thailand to get married and have received no compassion from anyone at this airline to try and get us there. I fly United for work quite frequently and have never experienced such horrendous service and lack of basic human compassion. I am flat out disgusted by United and will not be using them again, for personal travel or work related trips, because of this horrendous experience."

Cons: "Delayed flight due to "low air in tire" made me miss my connection to Iceland and ruined my very expensive vacation."

Pros: "The layover in Denver worked out perfectly - no long wait. The United entertainment availability. Friendliness of crew. On-time flight."
Cons: "The leg room. Small size of complimentary snacks. No screens for United entertainment so you had to use cell phone, but this eats battery and no power in our zone"

Cons: "2-1/2 hour delay due to poor maintenance"

Cons: "Seats in economy were cramped! Chair barely leaned back at all. Woke up with a sore neck. Cabin was freezing!"

Pros: "The flight attendant was trying to be accommodating. I and other passsengers bumped our heads when getting into seats. Can we say SMALL plane?"

Pros: "The crew"
Cons: "The seats r too small"

Cons: "It was very delayed"

Pros: "Nothing"
Cons: "That my flight got delayed in Denver over an hour and I missed my flight from LA to BJX because of that. I was suppose to land in BJX At 6am on Friday April 28th for a family emergency and now my next flight isn't till 1pm! This is the worst flight experience I have ever had in my life. Never in my life will I ever fly with united again. My plans got ruined, I was forced to sleep on the cold dirty floor of LAX. This cost me a lot of time and money, and I am upset about it. I will tell all my peers about this horrible experience and encourage them to never fly with united ever again. I do expect some sort of compensation over this horrible experience."

Pros: "Phone charger at every seat"
Cons: "Earphones for movie did not work"

Cons: "Very late."

Cons: "Boarding by zones causes passengers to have to stand longer while waiting to board, inconveniences them by having passengers seated in window and middle seats often arrive after the passenger in the aisle seat, and slows down the entire process because passengers settling into the front part of the plane frequently board and stow luggage while those seated in the back queue up behind them. Compared to boarding by row, the entire process is now one lengthy mess."

Cons: "My flight was ten hours late and no accommodations were provided. 40% off tickets to hotels and no way to get to them."

Pros: "I liked the power outlets that were available, as well as the USB! I have trouble sleeping on flights, but the great options for the in flight entertainment made it more than bearable. I will always choose to fly United now."

Cons: "Very bumpy ride....but I realize that can't be helped"

Pros: "Amazing plane with great features! Incredible staff!"
Cons: "Bathrooms should be bigger"

Cons: "Delayed and got downgraded"

Pros: "nice flight attendancts"

Pros: "Good crew, smooth flying, on-time"
Cons: "Crowded"

Cons: "Flight turned around and I was merely given a voucher for a hotel. This was united's fault; it was not caused by weather. Now I'm responsible for paying $80 for a hotel room. I'm furious. I will never fly united again."

Pros: "There was a lot of space and a quick departure."
Cons: "When we got to LA event though we were early we had to wait. I know its not the airlines fault but it sucked."

Pros: "The crew was very kind to everyone and it was a very pleasant flight!"

Pros: "Crew was great"
Cons: "Aircraft interior is dated."

Pros: "Hard working efficient crew. On time; a pleasant flight. Excellent flight attendant who covered all requests on her own."
Cons: "No problems"

Cons: "The plane temperature was ice cold and I was miserable the entire flight home"

Cons: "Nothing"

Pros: "The kindness of the staff."
Cons: "Having to go back to Denver because of a storm-in Omaha."

Pros: "I"
Cons: "I think United is improving constently"

Cons: "Seats are not comfortable and no leg room"

Cons: "Crew was not particularly friendly. One man was brusque when I asked for water to fill my small bottle. Rare since most crew members I've experienced have been very pleasant. Snacks were pretty paltry. Ned to serve some biscotti."

Pros: "Everything went smoothly, and that's really all that matters. The crew was great."
Cons: "Don't know why we have to pay for entertainment. It used to be free."

Pros: "I liked the flight attendants that they were courteous and helpful"
Cons: "I am a fearful flyer and that is putting it mildly. I didn't like that the pilot didn't introduce himself and talk to us about the flight."

Pros: "I liked nothing"
Cons: "I didn't like everything. All my United flight were delayed, the international was cancelled after waiting for 7 hours of delays."

Pros: "Crew nice and friendly."
Cons: "Free in-flight entertainment should be offered on all flights of 2+ hours through the United app. Had a family with young kids next to me who would have benefited from it (I saw the father trying to connect to it through the app), and overall it would make the flight a much more pleasant experience. After boarding a full hour later than what was originally said, it would have been nice to kick back with a movie for the flight."

Pros: "I know it's some sort of miracle. But there was only 40 people on an airbus. We all had about 3 seats each and we made full beds for ourselves."

Cons: "Boarded and left late for many to miss connections. No real help to get to new connection both on plane and off."

Cons: "Delays! Numerous delays! No assistance to help with changing missed connections or getting a hotel while stuck in Chicago."

Cons: "Great employees!"

Pros: "A everything was fine other than..."

Cons: "Horrible flight delayed an hour and the. Waiting an hour for my bag to learn it didn't make flight even tho I was at ther airport 2 hours before flight left. They said couldn't deliver it until the next day so had to go back to the airport to get my bag! Horrible experience !"

Pros: "People at desk in Chicago very helpful"
Cons: "Terrible communication about flight info caused us to miss a flight. Limited desk hours made it a painful experience. I will never fly with Aer Lingus again!"

Cons: "On April 15 we flew from Sacramento to Basel, via Los Angeles and Munich. We did exactly what we were told re reserving seats. We were told to call 23 hrs. in advance to reserve seats. When we tried to follow directions, we were not able to check in. Without checking in, we could not reserve seats. After numerous phone calls, to various numbers, we were not able to check in or reserve seats. By continuing to ask questions, to try and understand, we were told we were "under airport control". This was an "at random" situation and online check in was not available. Only 5 minutes earlier, we were still being instructed to check in online! We had never heard of this. I contacted a neighbor, who flies often internationally and within the U.S. He said it had happened to him once. He agreed that driving to the airport in Sacramento was a wise decision. This is not what we wanted to be doing 1 day before departure. At Sacramento we found a kind gentleman who saw our dilemma and checked us in as a favor. We saw assigned seats. He suggested we request to improve our seats the following travel day. It was a very challenging morning. As I tried to improve our seating the following day I was told, by airport staff, that this happened because we booked through Kayak? Rather with an attitude that we should have booked differently. This was a vacation we had looked forward to for years. I worked hard at not letting this difficult start damage my trip. Upon arrival in Amsterdam, I tried to learn more, to prevent a similar situation on the way home."

Pros: "Love the free tv/movies with the United App. That was great!"

Pros: "I liked how the flight attendants treat people in this flight. Thank you all."
Cons: "N/A"

Pros: "As above"
Cons: "As above"

Pros: "Good flight attendants"
Cons: "Small seats"

Pros: "I like how I made it to my destination even after a huge blizzard in Denver."
Cons: "We were really delayed while on the air plane and the seats were not as comfortable as before. I understand that the delay is not the crews fault but actually DIA, but it was my least favorite part of the trip because it made me late to an appointment in Tucson."
