Scores according to KAYAK customer reviews
Pros: "Crew was very good."
Cons: "Seat 2L Rocked back-and-forth every time person in seat 1L moved. This was a day flight from Chicago to London so I wasn’t sleeping. I could see if you were sleeping and had to deal with all the seat movement it would not be ideal."
Cons: "The landing"
Cons: "They switched planes last minute in Chicago that delayed us by 55 minute which led to us missing our connecting flight in London. That connecting flight,4 1/2 hours later, was delayed, twice! We had to rearrange everything waiing for us at our final destination. BTW there was no explanation nor bad weather to cause this problem."
Pros: "Loved the food that was served for my flight and the complementary beer."
Cons: "Well, the seats could have reclined more but this is the price you pay for air travel :)"
Cons: "Kept the lights on for too long serving dinner. Forgot to serve the middle section beverages during breakfast."
Cons: "It was not clear that I needed a different 6 letter code to checkin using the AA website. I finally got frustrated and called AA only to find out the code was different. The codes should have been the same or you should have referenced it on the website when I tried to check in"
Pros: "Nothing much but the crew made up for some of it."
Cons: "ORD and the roads approaching nothing short of a nightmare. Chicago should be embarrassed by the whole experience at ORD."
Pros: "Great customer service, good food, great in flight entertainment"
Cons: "Rerouting, connection delays and lost baggage."
Pros: "Crew was great once we were airborne."
Cons: "Flight was delayed 4 hours and caused us to miss train to Florence and spend double the original price to purchase new tickets."
Cons: "Three + hour delay out of ORD, equipment problems. Even though she had a boarding pass, they would not allow wife to board. Some ticketing problem between AA and BA. Finally, they let her on. We were the last to board."
Pros: "What to like with AA?"
Cons: "Delayed by 2:38 hours at Chicago due to aircaft repair. Total layover 8:38 hours."
Pros: "Crew, food and boarding."
Cons: "Limited entertainment selection. Tight setting with minimal leg room."
Pros: "The plane departed and arrived as scheduled. Flight attendants weee courteous and responsive."
Cons: "I was cramped in Seat B."
Pros: "On an overnight long-haul the thing I hope for most is sleep. The crew rapidly started beverage service after takeoff. Dinner was cleared and lights turned down about 1.5 hours later, including three opportunities for beverages. Lights came back up only about an hour before landing. Despite that no one seemed rushed. Seconds were offered for coffee, passengers had time to use the restroom before de-planing. We likely had almost 4 hours of our approximately 7.5 hour itinerary to attempt sleep."
Cons: "Having said that, the seats are not made for my over 6 feet tall spouse and myself. More leg room isn't going to help a lot. There's too much room between our necks and heads and the headrest so we end up slumped over even if we recline the seats. Hoping to win the lottery so we can afford first class some day."
Cons: "More than 24 passengers on the flight from LAX to Chicago lost their connection to Venice After we landed in Chicago with 2 hours delays we all run to catch our flight to Venice and we got there 5 minutes after the flight was supposed to leave but was still there instead but we were denied access and send back to customer service"
Cons: "The delay in boarding the flight in Chicago that made us miss our flight to Nairobi and has cost us a lost luggage which was checked in at Chicago and has not been located to date"
Pros: "Regular updates from captain. I was very satisfied!"
Cons: "Little leg room."
Pros: "Great crew and entertainment. Fairly comfortable seats."
Cons: "Bit tight betweeen seats. Fortunately had three seats for two of us. Slight mechanical issue caused small delay that pilot tried to make up. Better food and amenities on Delta."
Cons: "I’m still hungry and incredibly tired. Nobody buys their main cabin extra product, so there’s many empty seats. Ripe for the families that don’t want to pay extra to sit together. Those families bring kids, screaming kids to a section filled with higher fare paying customers. The FA in my section had such big hips, that she knocked my shoulder EVERYTIME she walked by. Not only that, everytime she did the courtesy reach over to grab empty cups from the middle seat, she hit me with her trash bag. Woulda been fine had I been awake, but I was trying to sleep in between the bouts of screaming from the devil possessed kids."
Pros: "American Airlines Crew, friendly and personable"
Pros: "New plane, more headroom made the cabin feel more spacious! Friendly flight crew! Loads of entertainment options....free! USB ports in every seat!"
Cons: "Traveling in coach is never comfortable. Fan was difficult to direct, and air flow was not especially strong."
Pros: "Very nice plane. Nice, comfortable, uneventful flight."
Pros: "We finally got to Aberdeen"
Cons: "Departure times were changed, plane had mechanical problems flight delayed almost 4 hours, we missed our connection. The American Airline was closed. We called 3 times totaling over an hour to get a flight the next morning. We had to book and pay for our lodging & dinner (2 rooms for 6 people) A nightmare of a trip!!!"

Pros: "Great service"
Pros: "Things went as they should have got a 2 hour flight."
Cons: "The inside of the plane around the air vents definitely could use some cleaning."
Pros: "Nice crew Spacious plane"
Pros: "The food and movies"
Cons: "The lack of communication while waiting to board about why plane was delayed even though it was already there. Service was ok, nothing stood out nor was extremely bad."
Pros: "The empty sit next to me"
Cons: "The very basic food. Having to argue to get extra water to drink when I got seriously dehidrated The limited choice in movies"
Pros: "Direct flight Chicago to Paris."
Cons: "Uncomfortable seating. Almost 2 hrs delay leaving Chicago forced us to miss train connection in Paris. Bad layover times to get back to the States, almost 9 hrs was the only choice available."

Cons: "For being in first class, my seat did not recline so I couldn't sleep and audio for my entertainment center was not working"
Pros: "On time"
Cons: "Cold cabin"
Pros: "Boarding was more efficient than I expected. And the leg room was very good, but the seats were narrow. Narrow seats made it a bit uncomfortable for a long 13 hour flight. Crew was efficient and very friendly."
Cons: "The sandwiches were too cold - actually had ice cycles. Narrow seatingwas constricting and entertainment wasn't varied enough."
Pros: "We got to watch movies for free, and we got to eat twice as well."
Cons: "First, the original 90 minute layover became 8 hours with the old buy this scheduled ticket and 3 weeks later we will switch it to 7 hours. After a 8 hour red-eye, it was brutal. BA was an hour late taking off from London to Warsaw. The onboard experience was charge for everything. No sodas, water, nuts, etc. Oh and boarding, cmon. The gold, silver and special people go first. I think that was 5 people. The other 150 plus, you are on your own, go. You have your typical isle 5 person holding up the entire loading procedure, trying to get their oversized bag in the overhead, versus loading from the back. Wow."
Pros: "New Airbus Dreamliner is a nice plane."
Cons: "Not much"
Cons: "There was no wifi and no screen on the seat. I could not see the screen for the movie. Airline was old and also it took 2 hours to get going because they had to check the engine."

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."
Pros: "Winter storm commencement in Chicago during take off didn't daunt the pros piloting this Lufthansa flight. Smiling, courteous service, good food and wine along with space to rest has made Lufthansa my new go-to for flying to Europe."
Cons: "Economy seats mean tiny unresponsive video screens. Playing a game of Mah-jong on the in-flight screen is nearly impossible. Bring your own tablet"
Cons: "Flight was freezing cold and staff were very rude. Worst flight I have ever been on."
Pros: "Boarding process, including ground crew was good with customer service. Food was good and in-par with other airlines."
Cons: "Flight crew, including a few air-hostesses were very rude. Entertainment system and the played films were very dull. Plane was uncomfortable."
Cons: "I was exiting your airplane bathroom and my wife was entering when the flight attendant placed her arm in front of my wife and said, “I’m sorry but I’m working so that means I have dibs on this bathroom.” She then entered the bathroom and shut the door on my wife’s face. I was furious and speechless to witness such frank rude behavior and horrible customer service. I would like to think that United Airlines prides itself on better customer service than this. My wife and I have other choices when we fly and we will certainly think twice before we fly United Airlines again."
Pros: "Actually managed to sleep!"
Pros: "I like that the seats were more comfortable and had at least some padding."
Cons: "The gate had no comfortable seats and looked like a minimalists ' lounge. The gate agent did not actively give any updates to the boarding process."
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: "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."
Pros: "Polite crew"
Pros: "People were polite."
Cons: "I got my flight switched earlier. Paid $57 for it. Then this flight got delayed almost 2 hours so I ended up in NYC at the same time and it threw off my whole work day."
Cons: "Comfort, service.., terrible'"
Pros: "The flight was smooth"
Cons: "The seats felt stiff"
Cons: "Again, seats are too close front to back."
Cons: "Tight seating for transatlantic flight. More importantly avoid Toronto at all costs. Need to clear customs and go back through security again on a connecting flight. Takes forever. Food was not good at all."
Cons: "Explained above"
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: "How they canceled one of my flights just as I landed at my layover for that flight when I look back at Boston they had a direct flight ready for my destination. Very poor management I was stuck in Chicago with no money or food for hours then after they start boarding for my new flight they tell me that I may not be able to get on even with ticket in hand. It was a joke and very stressful"
Pros: "The gate at the Chicago airport was well designed. There was a line for each boarding group, and you could line up early. This is particularly effective for some Asian flights, which can sometimes be chaotic with many different nationalities all lining up."
Pros: "I broke my arm and all of the gate agents were wonderful trying and succeeding in getting me A seats for my comfort."
Pros: "Entertainment options"
Cons: "United chamged our arrival gate without a crew to man the jet way. So we sat for 20 mins this missing our connection flight."
Pros: "Good selection of entertainment."
Pros: "Flight from Calgary to Chicago was excellent!"
Pros: "Connecting flights in China need more of a layover I missed my connecting flight not happy it was a disaster going through immigration takes forever in Shanghai .."
Cons: "Delay and then having to change gates - at O"Hare that means walking and walking some more !! After being insulted during check in. The RUDE woman (poor English) with assisted boarding then the RUDE man that changed my name and my luggage he chose to send to Dayton OH -never been there in my life and he "dug" thru my luggage - as if he was searching for MONEY or GOLD -he pulled out a protein drink and I asked him to hand that to me so I could drink it as I am a diabetic - he shouted at me "I THROW AWAY'. During the two hour delay I could have used it !! Poor service I will fly American from now on !!!!!!!!!!!"
Cons: "While going inside the flight they told me there is no room for Carryon and gave me ticket to book the luggage. When I went inside the Flight there is lot of room to carryon's, why they have to lie this BS."
Cons: "One of the stewardesses had a terrible attitude. She was rude to people and rolling her eyes at them. She also seemed to be rude to her fellow co workers."
Pros: "The crew was awesome and the flight wasn't bad at all"
Cons: "It was suggested that I didn't bring my carry on with me so I left it to be voluntarily checked and it came back ripped"
Pros: "Great boarding at ORD."
Cons: "My seat"
Cons: "The flight was late by 5 hrs due to mechanical problems. The gate crew was confused about what to do and we ended up with several deboardings and boardings. Food was terrible. The entertainment system did not work."
Cons: "8 channels of looped shows and movies. Too long a flight for that...and then have to use my device to watch on the free part of the wifi.so no battery left. For this price? And I booked through Lufthansa but flew United. Bad form."
Pros: "the japanese speaking flight attendant was exellent! she was very observant to passengers needs. i was also pleasantly surprised by the entertainment system."
Cons: "there was a flight delay due to maintenance, which was inconvenient."
Pros: "Nice new plane"
Cons: "2 hour delay due to a name discrepancy on a passenger. Not fair to keep everyone waiting for one person"
Pros: "The vegetable ravioli we had on our flight was top notch and the crew did a great job of making sure everyone was taken care of on the flight"
Cons: "I flew economy, so I knew that I wouldn't be getting a lot of space. But I wasn't prepared for how much less space I would get compared to the other seats on the plane. I was uncomfortable for most of the trip."
Pros: "Very funny and skilled captain. Comfortable seats with lots of leg room"
Cons: "Crabby flight attendant"
Pros: "United offers so many free movies and shows it makes the flight fly by."
Pros: "Glad you didn't give priority to those with other designations like priority plus etc"
Cons: "Plane late leaving Chicago due to no pilot."
Cons: "Long delay for maintenance. Barely made my connection in Munich."
Cons: "I ordered and paid for food that they forgot to serve me. I had to go to the back to ask for my food. When I did they were rude about it. UA has offered a coupon for 50.00 that I can use if I fly with them again-- which would cost about 1000. No thanks, United. I'll fly with China Air."
Pros: "No delays."
Cons: "No complaints."
Pros: "On time arrival, the food, the crew"
Cons: "No power outlet and very old entertainment system. United has introduced a nice wifi-based entertainment system but if you do not have power outlets to keep devices up the system is pretty much useless after one movie or less."
Cons: "Not only did we sit on the plane for over an hour before taking off, but on an over four hour flight I was refused water towards the end. When I asked for more than one glass I was rudely told and I quote, "you know what? No. We have other passengers who may want water." Are you kidding me? I sat down feeling scolded and like I asked for something ridiculous. We landed after 2am and most of the passengers were sleeping and I doubt anyone asked for more water since I didn't see the flight attendant move again. Perhaps she was upset that I interrupted her from reading her paper? Extremely displeased with my experience. I"
Pros: "The last row was really comfortable."
Cons: "The lines set up to let people onto plane were disorganized."
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."
Pros: "Mechanical problem, changed planes and left 5 hours late. Missed my connection to Taipei. While the airport hotel we were sent to was adequate, it wasted an entire extra day to get there."
Pros: "Can't say I liked anything about this flight or my interaction with United about it."
Cons: "Where do I start - tried not to select a seat until boarding, so I can get a chance at seating up front of the cabin - the online system selected one for me anyway that no one could remove. With 20+ seats open when I left for the airport - in the 20 minutes or so until I got there, they were all taken and I was stuck in a seat in Row 37 in the back of the plane that I didn't even select. The Premier Access line was taking 40 minutes to process and had to be moved to a regular line that took only 10 minutes. Plane was an old 767 with my seat mate overweight and spilling into my seat - since flight was supposedly full , no chance to switch. Flight attendant light wasn't working and had to go to them myself to get headphones that weren't provided. Overall, horrible experience I wouldn't want to relive again."
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."
