Pros: "Economy class seats better than UA."
Cons: "Economy class seats always have room for improvement."
Cons: "I didn't have enough time and had to rush to get to me connecting flight. It scared me that I might not make it to the terminal and gate in time. thanks!!"
Pros: "American airlines is located in a small terminal at CDG which works to its advantage. Compared to other airlines, getting to the US from Paris is a lot easier. The airplane was brand new, entertainment on board is the best I've seen in a long time. In Chicago, clearing immigration and customs was a breeze, the airport is very well designed for international travelers."

Cons: "Boarding was chaotic."
Pros: "friendly staff"

Pros: "The boarding was quick"
Cons: "I am surprised that an 8 hr international flight, had no WIfi.. I had to continually ask and check the time with Crew members. This needs to change when the average seat is $800-900 and the flight holds 35 seats. AA is raking in WAY to much money to be this cheap. No WiFi and having to look up to the middle isle to watch a child's movie on repeat " Guardians of the Galaxy." My neck and back were in extreme discomfort from the 8 hr flight back to NYC. If AA had headrest monitors and WiFi this could be avoided. Its 2017 stop being cheap!"
Cons: "My flight got cancelled and then the flight I got rebooked on also got cancelled so I had to spend the night in an airport and miss a day of work."
Cons: "Airline throughout mentioned connecting flight passengers are okay as the flight will land almost at the scheduled arrival time but once onboard bluntly announced that we don't have further information. This is cheating"

Pros: "Boarding was quick, but rushed."
Cons: "- plane was extremely hot, no A/C until boarding was complete and on the runway. So about 45 minutes of heat. - no entertainment units - no food, just pretzels and cookies, one drink - seats not comfortable, even with Main Cabin Extra"
Pros: "Ticket price was competitive."
Cons: "No individual entertainment systems on the seat backs--4.5 hours is a long time to be sitting on a plane with only an overhead screen showing whatever movie the airline chose. Also, charging $125 for a carry-on pet that has to stay under the seat AND having it count towards as one of my two "free" carry-ons is ridiculous. The flight was delayed because one of the crew was late."
Cons: "The gate the flight was originally on changed, however there was never an announcement made over the intercom advising of the change. When the gate I was waiting at finally showed the flight information to Toledo, I had to find what gate I my flight was now on and had fifteen minutes to make it to the correct gate. Had the original gate displayed the new information any later I would have missed my flight."
Cons: "The cabin crew for first class spent more time talking with each other and a pilot that was on our flight than with those flying. When they started passing out snacks they forgot the plates that had the napkins and utensils and were supposed to hold the snacks."
Cons: "Plane was late because of malfunctioning jetway"
Pros: "Ordinary flight, not too chaotic for holiday weekend."
Cons: "My luggage was lost! Had to wait an entire day to recuperate my suitcases."
Cons: "Late by 40 min"

Pros: "Easy boarding. Served food and beverages. Comfortable flight"

Pros: "Thank you for the new, comfortable plane"
Cons: "No IFE on 6 hour flight."
Pros: "Very comfortable flight. All I did was sleep and watch movies, it was great."
Cons: "They didn't let him to aboard, because of a mistake on the name. I called to ask for help to fix the name and the person who answer me asked me for a numeric code and I didn't know where to find it. He was very rude, didn't help at lot guiding me where I can find it, but instead he said " You have to call back when you find it" I asked him that I couldn't find it and he almost yelled at me saying DID YOU GOT a RESERVATION OR NOT?. I never found the numeric code he asked for. So I called again and fortunately somebody else answer my call and she was a litTle more helpful and didn't made me waste my time with a numeric code. She asked me for the Trip ID # and I found it right away. VERY DISAPPOINTING. I LOST 700 DOLLARS. I HAD TO BUY ANOTHER PLAIN TICKET!!!!!"
Pros: "not beat up"
Cons: "people trying to get extra carry on on"

Cons: "Better food and drink options."
Pros: "Comfy plane"
Cons: "Food so so in economy"
Cons: "The bathroom on the flight from Denver to Santa Barbara was the WORST EVER! I doubt it has ever been cleaned and the poor people that had seats near or at the rear of the plane should have been refunded their money having been subjected to the smell of an “indoor outhouse!” Shameful!!"
Pros: "Poor customer service and not understanding."
Cons: "Don’t now it’s not the company’s fault it’s just the representative that I spoke to. I don’t know how many times I could explain my situation, and my English is not poor and I thought I was explaining myself clearly. Best think I could do is just say forget it I’ll take my $ 430 dollar last."
Pros: "The service on the non stop flight United Airlines from San Francisco to Osaka was excellent."
Cons: "I wish there could be more movies about nature on the entertainment network."
Pros: "I found the reason for being late to be questionable They said heavy snow but as i flew in i looked out the window and saw all roads nicely cleared That does not happen in 3 hours"
Cons: "They did not get my liggage to the connecting flight And here i am in Ukraine with no winter clothes at 7 below 3 days later"
Pros: "The Boeing 787 plane was very nice. The window shading control is unique!"
Cons: "Thanks United for keeping my diet in check."
Pros: "787 is starting to show its age but efficient and comfortable 3 3 3 seating. Reasonable as you can expect crew., do the minimum required."

Cons: "Not enough food for such a long flight"
Pros: "Boarding was smooth and entertainment was ok"
Cons: "In a 12 hrs journey only two meager meals were provided."
Pros: "The complimentary meals were good and I wasn't given too much. The flight attendants were very friendly and polite (and it was amusing to listen to how the English and Japanese pilot announcements differed, since the culturally-expected tones are WAY different.)"
Cons: "It was kind of hard to sleep on the plane. I ended up propoing up the armrest next to me and leaning my pillow against it, which sort of did the trick. My hips hurt from sitting so long, so maybe there's some kind of cushion technology that can help with that."
Cons: "Flight was delayed. Super small aircraft so suitcases didn't fit. Didn't have food options, just pretzels."
Pros: "Flight attendants were very nice"
Cons: "The overhead a.c. spout didn't work. Plane was very hot."
Cons: "I didn't like buying a ticket for a flight with an ANA number and advertised as ANA but then flying United. I don't want to fly united."
Cons: "Zero regard for customer service. I will never fly United Airlines again, I may never use Kayak again either. This was the worst travel experience of my entire life."
Pros: "We got there safely and on time."
Cons: "Bathrooms too small and unsanitary. Sick people on board spreading germs. Headphones fall out of kids ears. Airplane too cold. Food not good. Bread is terrible. Wasteful packaging and serving of food. Nowhere to throw away trash. Bad timing and content of meals based on final destination."
Cons: "Was told at check in that my flight was delayed and would not make my destination today. When I asked if there was another flight I could get on, they told me the upgrade would be over $1000, and that it wasn't their problem. Rudest customer service I think I have ever dealt with! I won't ever fly united again!"
Pros: "More fights to choose"
Cons: "Could not choose the seat at the time booking"
Pros: "That we got to Little Rock early"
Cons: "I had ordered ginger rail and the lady brought me a Diet Coke I told her I don't like Diet Coke because I don't drink Coke and she said I thought that's what you want it now you have to hold onto it until they come back and pick up the trash and she never brought me the ginger rail to drink she walked away and I never drank nothing on the flight back to Little Rock that lady was so rude"
Cons: "Food, like all airlines, is so lacking even though airlines are making record profits while lessening service (crowded, fewer flights, baggage fees, etc)."
Pros: "Great staff and everything on time"
Cons: "That a bunch of travelers including myself missed our connecting flight in Chicago after united chamged our arrival gate but didn't have any crew to man the jet way. We sat for 20 mins right in front of our gate. From 1 pm to 10 on my flight to Asheville from Chicago was delayed many many times waiting for our airplane to arrive. Upsetting that we missed our connection due to United's poor planning, they didn't hold our connecting flight for us but we had to wait all night for other flights."
Pros: "It was so smooth.No long lines ,no delays,a straight thru flight.And on Christmas Eve morning."
Pros: "The travel agent, Tim, in STL worked very hard to get us on a flight."
Cons: "After a cancelled flight, two delays and lost luggage (that we did not receive for two days after arrival) on the way to Boise, we've now been cancelled on the way home to St. Louis. The first cancellation was due to weather. The two delays were due to late crew and refueling issues. Today's cancellation was due to maintenance. Embarassing. I travel often and can guarantee I will never fly United again."
Pros: "Very smooth and easy. Thank you"
Pros: "Fast and smooth"
Pros: "we left right on time. It was a smooth flight and a nice aircraft. did not use entertainment so no comment there but was a good experience overall."
Pros: "Attendants were nice."
Cons: "I booked the comfort economy seating that I normally do with Delta. With their additional cost you get a larger seating area, free in-flight movies, reserved compartment space for your carry on and a free drink. No such thing with United. They did try to have movies through their app, but it wouldn't play long enough to allow you to watch."
Cons: "The flight attendants were disrespectful to not only me but to other passengers. They were not attentive! The plane was dirty."
Pros: "The flight was delayed, but once I got on I had a great flight!"

Cons: "Not a fan of the snacks that were served."
Pros: "Short flight, direct"
Cons: "Wifi misleading, sounds like free but not."
Cons: "I think that after first class they should load the plane from the last seat forward for ease of getting to the back seats"
Cons: "Charged 50.00 for check bags,when that was included in the online purchase,not happy and probably will not use either again!"
Pros: "prompt emails and text messages with the back up plan"
Cons: "Missed connecting flight because flight delayed takeoff from home due to SFO problems. Sat on tarmac for an hour or more, finally took off but missed connecting flight mid afternoon and no other acceptable flights until 11 pm getting into Fort Lauderdale at 730 am. (originally was supposed to be getting to Fort Lauderdale at 10 pm). Also, the aisle seats on the plane had a narrower underseat space that my little boxy carryon wouldn't fit into--and it usually fits under any underseat storage...Luckily the passenger in the middle was willing to swap places."
Cons: "Worst ever Can you credit my credit card for a full refund"
Pros: "Boarding and.crew awesome. Crew helpful, friendly, and efficient."
Cons: "Didn't like to have a fee for my bag. Have to pay for wifi"
Pros: "Flight to Austin was just fine."
Cons: "My flight back to bosie from San Francisco they changed the gate I didn't hear the change and missed my flight. I didn't get back to bosie until the next day."
Cons: "United are the most rudest phone people on the phone to deal with and if it's there fault they never want to comp u last time I fly with united"
Pros: "Flight was on time"
Cons: "That u load the plane assistance backard,loading goes much faster if you start @the back of the plane,& myself I carry only a shoulder bag only ,all the time. U put me @ the back of the plane 90% of the time which means I have to wait for the people that are moving their whole house,making me miss my schedule, I have to spend night @ airport for next schedule."
Cons: "no inflight entertainment."
Pros: "I arrived on time."
Cons: "Flight was ok. I was disturbed by the rudeness of flight attendant toward a service dog. This dog was the owners eyes and she seemed disgusted it was there. We had to let her know in front of other passengers so she would be put on the spot and change her attitude."
Pros: "Luckily the crew on this flight was friendly and courteous, unlike United flights I had 2 months ago, because everything else was pretty horrible."
Cons: "First, we were delayed over 2 hours for maintenance problems. Second the plane was cramped and the seats were hard as park benches. Third, this flight had zero entertainment options although they advertised for it in the seat back propaganda. Fourth, the cabin noise from the engines, once they got them started, was so loud that even my noise canceling headphones could not prevent me from getting a headache. At least we got there safely, eventually."
Pros: "Not only do I get the best price. The fact that you told me what carousel to get my bag from was new to me. I alway check kyak first but now I love u guys. I know my travel site and its kayak"
Pros: "Not a single thing!"
Cons: "I almost missed my flight, because at check in they were only helping Premier passengers. Forced to wait for 45 minutes. All I wanted to do was check a bag! When I finally got to the counter, the customer service agent was extremely rude, slow and frustrated. I had to run from check in to security and only made it to the plane with seconds to go."
Pros: "Free entertainment on mobile devices"
Cons: "TSA pre check did not register from website, had to use standard security line. No boarding or seating preference for military."
Pros: "Newer plane so seats were cushioned better, crew was attentive. Great landing on icy runway."
