Scores according to KAYAK customer reviews
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!"
Cons: "The flight was cancelled. I didn't receive a refund or free hotel accommodations. I've been on flights in Africa where free hotel accommodations were standard for a layover over 3 hours. A little embarrassing that an airline in America can't afford a hotel for people stranded in a city overnight."
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: "Flights lately have been a huge disappointment but American Airlines was great! Crew was so pleasant and helpful,food was good and the "entertainment" was too! I'll definitely fly with them again!"
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: "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"
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: "On time"
Cons: "Cramped seats. Entertainment system outdated"
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: "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: "Timing and transit time was excellent"
Cons: "Food was horribe and no dedicated tv per seat"
Cons: "We were delayed for 6 hours due to a maintenance issue. Horrible customer service"
Cons: "Always a problem with these guys"
Pros: "Couldn't of been more impressed especially after being hung out by Southwest!!!"
Cons: "We have flown to Europe recently on SAS and that airline was so much more comfortable than airberlin. Things we missed: personal TVs on the seats, good leg room (airberlin was quite cramped), and small attentions like a disposable towelette. I got no sleep on airberlin."
Pros: "Staff was very friendly and helpful"
Cons: "Experienced 4 hour delay with mechanical and weather problems. But glad they put safety first"
Pros: "They put safety first"
Cons: "Frustrating 4 hour delay"
Pros: "Vegetarian pesto pasta was good, but all other food was not good and way too sweet and sugary."
Cons: "Flight was delayed several hours, entertainment system did not have many choices and stopped working early in the flight."
Cons: "I am very disappointed in my flight. I am 6'7 and paid for an exit row seat. When I got to the airport they gave me a different seat with no leg room. They told me they changed planes and there was nothing they could do to help me. I tried again at the gate and again nothing. Will never fly again."
Cons: "The flight attendants were rude, they had no dinner, no healthy breakfast options, they rationed the beverages and after being without enough water for 12 hours, they would give you dirty looks when you asked for a second serving of plain water."
Pros: "Room on flight in coach was sufficient and im 6 ft 2"
Pros: "My original flight was canceled and booking agent was able to get me on the earlier flight."
Cons: "Stewardesses did not pick up trash near the end of the flight. I had to hold it until we landed."
Pros: "The entertainment was pretty good . There was a good variety of movies and music"
Cons: "the cabin was extremely small, absolutely no leg dpace unless you were in first class, specially if you are a taller person."
Pros: "Overall pleasant experience."
Cons: "I was not aware that the FinnAir flight was being handled by American. I missed it when reading my itinerary and had a brief panic when I showed up to the international terminal and my flight was not even listed on the board. Perhaps it could be written a little larger? Thanks."
Pros: "Good value"
Cons: "Poor food quality"
Cons: "That small space!! This is a long flight and you have no room to move around at all!!!!!"
Pros: "Appreciated that the cre didn't wake me to give me my landing card. They did make sure I got one though."
Cons: "I didn't get vegetarian food that I ordered over the phone and I did made sure that it said vegetarian Jain meal on the ticket that I printed. Very disappointed because no point ordering then. I paid $1234 for the trip. And I am traveling because of funeral."
Cons: "Seats too tight. No room"
Pros: "Food, entertainment and free checked bag. Can ask for more!"
Pros: "In flight service."
Cons: "The first check in kiosk associate was turning us away because we reached 30 minutes prior to scheduled departure. However, by then they knew that they were going to be at least 1 hour 30 minute late. Then when kayak emailed us about the delay, the check in people let us in. Ultimately the flight was three hours late."
Pros: "Food, blanket & pillow,"
Cons: "Most of the video screens did not work. Long flight with no entertainment!"
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."
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!"
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."
Pros: "On time"
Cons: "Uncomfortable seats and lights left on so I couldn't sleep."
Pros: "There was a good entertainment system with a lot of new options."
Cons: "My itinerary said I fly on Brussels Airlines on a specific flight number. I went to the international terminal to discover it is not there. I then asked multiple aiport staff members if they heard of Brussels Airlines and they said they did not. One person said it may be terminal 1, so I went there based on very little information and with hopes it would be there. I got to terminal 1 to discover there is no Brussels Airlines. I walked to Lufthansa because my return flight is through them, but it was not there either. At this point I have 45 min to make it through security and board, and no one can tell me where Brussels Airlines is. The good news is the flight was delayed, and I got an email from United Airlines with the flight status. This is the first time I was contacted by United and there was a completly different flight number than the itinerary. United should be more clear on the airline and terminal information for international flights!"
Pros: "was upgraded"
Cons: "small video monitor"
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"
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: "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: "The flight was smooth"
Cons: "The seats felt stiff"
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: "-Complimentary Snack and beverage -Can pick your seats when booking -Changing Tables in restrooms -Entertainment options -Early boarding for families with small children"
Cons: "-Free Soda but charged for water -Had confirmed seats but then our party with 2 toddlers got split up -Semi convenient( rather small could hardly fit a 1 year old) changing table but then flight attendants threw a fit when a stinky diaper was changed in there. -Had to have special programs on device to even play anything, thought I had everything on for return flight to watch movies but nope still needed something extra Wifi only works for United App and Website -Waiting in the shorter line to preboard with our 2 toddlers only to be cut off by a Global Travel Program(?) family with 15+ people"
Pros: "Bigger plane more smooth ride the pizza was excellent"
Cons: "The running to the next plane in 15 min because of the delay the landing was hard"
Pros: "The flight attendant was really Nice"
Cons: "The agent at the gate were not helpful, we somehow got seats at opposite ends of the plane. Rowm17 and row 40."
Pros: "United got me from point A to point B"
Cons: "Crew was rude, not just to me, but to other patrons. Flight was packed going and the man scanning boarding passes spoke to those of us asking simple questions as if we were stupid and defiant. Was he a prison guard in his previous job? On the way to Newark, I had an aisle seat. One of the stewardesses blazed by me with a cart ramming it into my shoulder without so much as a, "sorry." I'm not a big woman but maybe as I dozed off I leaned over a bit...There is no way she didn't feel her cart hit me. Rudeness, it seems is a part of the culture at United because the flight attendants coming back squeezed past the long line for the bathroom without saying, "excuse me." They did however, say, "I need to get by," and one of them brushed by the gentlemen sitting next to me and bumped his laptop and coffee. Overall it seems that the crew working these particular United flights have forgotten that we pay hard earned money to fly. Some of us are going on vacation, to see loved ones, and some are flying to deal with unpleasant circumstances. The staff may fly several times a day, but most passengers do not. There's a lot of prep and anxiety, that goes into taking a flight and a surly flight crew multiplies that anxiety. No one wants to fly with a crew that hates their job."
Pros: "The flight itself was ok."
Cons: "They have lost my bags. I won't receive them till Friday."
Pros: "It was uneventful during the flight."
Cons: "It was very late due to weather in Chicago so we missed our train in Paris. But otherwise great flight."
Pros: "The flight overall was great, easy to board and de-board, and a smooth process from start to finish."
Cons: "Connecting to the in-flight wi-fi to watch movies and tv shows was nearly impossible."
Pros: "Loved that it was an empty flight"
Pros: "The service was good"
Pros: "Friendly flight attendants, helpful staff at the ticket counter."
Cons: "Unable to check into both legs of my flight even though Air Canada used United for the first leg."
Pros: "The crew was doing their work well."
Cons: "At the boarding gate over 30 people were in line to get a seat number. I thought I had successfully selected my aisle seat online but was arbitrarily given a middle seat. I tend to use the washroom often. I had to climb over a sleeping passenger many times, without waking him up. One gentleman had some serious problems there but it was clear he was not getting any resolution. he was obviously very very frustrated. Syrupy sweet noodles?"
Cons: "Two hour delay for start of engines.. Not enough chichen and pasta was not good"
Pros: "The flight was a head of schedule and very smooth."
Cons: "It was freezing cold. I was wearing a sweater and was freezing."
Pros: "I have metal leg braces. The staff was helpful getting me from terminal to terminal. They were very helpful."
Cons: "Having a leg brace makes difficult I am blessed I can move a little without them. I had to move a short distance without my brace. No place to put it back on."
Cons: "i missed my flight because my flight left Toronto late"
Pros: "Pilot was very happy and friendly! Very informative throughout flight."
Cons: "On the return home, I was seated in the last row right next to the lavatory. I was bumped into at least 40 times by other passengers and flight attendants."
Pros: "not a damn thing"
Cons: "Weather delays are a typical part of travel. What's not typical are 5+ hour delays and sitting on the tarmac and watching your connection take off without you. First Class seats morphed into Economy center seats the next day, with nary a hotel room in sight. Thanks for nothing."
Cons: "The flight was very hot and uncomfortable!"
Cons: "This flight never happened it continued to get canceled and canceled!!"
Cons: "seats were very uncomfortable"
Cons: "We got on board, waited 20 minutes. Capt said it was a bad reverser, and we were waiting on paperwork for 15 minutes. Long story short, they make us leave the plane after 2.5 hours. Then we wait in the airport for another 2.5 hours. I missed my connection and spent 10 hours in Chicago."
Pros: "The flight attendant finally took care of it after I complained a couple of times."
Cons: "That you changed our seats, and, that there was no room in any of the overhead bins. So, the flight attendant told me that I needed to fight my way through the people coming toward me back up the aisle and check every overhead bin all the way back up to see if there was room for my one suitcase. Others had brought more than one bag up there. Finally they checked my one carry on bag. The ride was also really bumpy, worst that we've ever experienced. But that was due to weather conditions."
Pros: "The flight attendant was great! Pleasant, polite and professional!"
Cons: "The flight from ORD to ABE was on a plane with expired maintenance logs or inspections? We were delayed 2 hours in arriving for what seemed like a pilots lax in paperwork. But what does a customer expect from an airline who knows they that customer by the balls?"
Pros: "We were tossed into the last row; I had no leg room and was constantly being bumped by people using the rest rooms. As a result it was a sleepless flight."
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."
