Pros: "Flight was comfortable and smooth all the way"
Cons: "Tastier food options"

Pros: "Average flight. Crew was polite."

Cons: "We weren't alerted there was a chance of delays. Over two hours late."

Pros: "The cabin was to warm"
Cons: "The cabin was to warm"

Pros: "Great seat easy flight. The food always seem to be the same. I wish they would change it up every once in a while. I've been on this flight 14 times this year and its always exactly the same.."
Cons: "The gate was under construction in Seattle, and it was impossible to hear the gate agents."

Pros: "Crew were attentive and the food service schedule was helpful in making the time pass. wonderfully generous pours on the complimentary wine service"
Cons: "Food was really just gooey goo."

Cons: "They did not have a “gate available” for our arrival so we have been waiting in the plain on the tarmac for over fourty minutes and still waiting. This is ridiculous. We purchase tickets at delta for a plain that had a departure and arrival gate. This should not be happening"

Pros: "Super friendly staf, big enough seat, good enough food, enough room for luggage."
Cons: "Seat was smaller than EVA and food not quite as good."

Pros: "Great staff and they worked hard to make the flight comfortable."
Cons: "The seats are small and the plane feels like a Sardine can."

Cons: "Did not serve the food we asked Limited choice of movies"

Pros: "Great flight attendants and crew, 30 min early!!"
Cons: "Nothing"

Pros: "Food, service and entertainment"
Cons: "Entry into the aircraft was a bit chaotic"

Cons: "Had a 5 hour layover - booked first class but this did not entitle me to use the delta lounge in seattle. Snacks only on the flight."

Pros: "I loved flying delta comfort. I’m going to do it more often."

Pros: "absolutely nothing"
Cons: "The crew! So slow! Not helpful with your questions/request and the attitude! What on earth! Awful customer service!"

Cons: "Too many interruptions on the inflight entertainment."

Pros: "Loved the swift checking in at Seatac, being picked out of the Special check-in line, tended to by a Ndeye, smooth all the way through to the gate. Also liked that the plane's arrival at Schiphol was only 30 minutes later than initial ETA after long delay at Seatac. Also liked the many snacks."
Cons: "Prolonged delay of flight departure. Choices of entertainment, especially movies."

Cons: "Old cramped untidy and limited drink service"

Pros: "Good food, excellent service"
Cons: "Seats did not have enough storage."

Cons: "Seats a bit cramped"

Cons: "The crew appeared tired, scattered, and unhappy. The flight was delayed after boarding nearly 1hr while repairs were completed. 1st announcement by captains crew stated passengers could disembark during repair, then stated 10min later to take a seat. Very poor communication."

Pros: "Wifi for entertainment worked well"
Cons: "No longer have entertainment on back of seats"

Pros: "Getting to China, albeit two days late."
Cons: "The fact that the lack of knowledge regarding international travel visas by the counter staff and supervisor meant that two days of the vacation were lost. Upon arrival in China the 144 hour travel visa was granted with no problem within minutes, but the U.S. staff was completely befuddled by the possibility. The interrogation was completely stressful and resulted in a reschedule of the original flight and during the second attempt at flying even an email from the U.S. consulate with a link to the Shanghai/Chinese government immigration site was deemed "not official enough". i will be expecting proper compensation. I was once given an $850 travel voucher for voluntarily giving up my seat, and was flown first class to Hawaii, given 4 star accomodation and then flown first class on to China within 48 hours. This was an involuntary bump from our chosen flight time, all because of a lack of knowledge about current visa regulations and international law on the part of the check in staff. We have been loyal Delta users for over 15 years, and this was the biggest blunder ever. Also humiliating and extremely frustrating, stressful and a big problem with fulfilling our travel plans between son and father."

Pros: "The entertainment system had a wide selection of good movies to watch."
Cons: "The seat was busted and could barely recline at all."

Pros: "Great staff, polite and helpful"
Cons: "Small seats"

Pros: "Very attentative."

Cons: "Aircraft was smelling bad! Hygiene is the key"

Pros: "Helpful staff. Never felt rushed if I had a question. The special meal (VLML) was excellent. Tasty, filling and nutritious Plenty of foot room in economy."

Pros: "Nice Pajamas. Individual window seat. Decent food."
Cons: "Seat ptich could be/should be - wider. Snacks can be better and have better option.. ( only Apple for a fruit? Gimme a break)"

Pros: "Nothing. Delta sucks!"
Cons: "Poor management prior boarding"

Pros: "The movies."
Cons: "Horrible food and Very very uncomfortable seats. Absolutely NO leg room. One of these days Delta is going to be sued for deep vein thrombosis (blood clot)."

Cons: "Crew forget to feed quarter of passenger, and did it after reminder from passenger. No movies with Russian translation or titles. Flight arrived at Amsterdam 50 min later, and we missed our direct flight to Kiev"

Pros: "Economy seats are comfortable. I wasn't compressed in any way sitting in a window seat. Delta is my go-to airline. Not always the least expensive, but it's usually a pleasant trip."

Cons: "I was disappointed to be overcrowded in my seat. I sat next to a man who was too large to position the arm rest between us down. And as such, he took up about 1/3 of my seat. It was a really cramped flight and although I was polite, it's still very frustrating to pay for a seat, but only get access to 2/3 of it. I am 6'1, so every inch of my seat is typically used. It would be nice if there was a way to ensure this didn't happen. If people need more than 1 seat, they should be required to pay for more than one seat, and not 'steal' my space. Overall bad Delta experience. Sara"

Cons: "Must have been an older Delta jet. It had no entertainment. The wifi was poor."

Pros: "Nothing"
Cons: "Missed original connection, booked on a three hour later flight that was delayed another hour, then three hours. Finally switched to Alaska 2 hours prior to departure. Was assured our bags would be on Alaska flight. They weren't. One eventually showed up in Spokane at 2 a.m. on a Delta flight the other on a separate Alaska flight at 3 a.m."

Pros: "Crew was very helpful."
Cons: "This flight was delayed 5+ hours past its scheduled 12:15 departure due to mechanical issues with the plane. Delta was only able to offer a $50 travel voucher for this huge inconvenience."

Pros: "Finally, a free movie! Now, whoever picks the movie needs to do a better job, but atleast it was something! Service was Excellent, first pass with snack and drink carts, then they came through with coffee, and again with water! Now, that's service! Great job! Very friendly staff."
Cons: "Bathrooms, once again... disgusting. Urine on the floor, smelled awful. Tiny bathrooms, only 1 up front"

Cons: "Boarding was 30 minutes late."

Cons: "I was surrounded by a basketball team. They all have terrible breath. I know that because they kept talking to each other and I was in the middle (literally) of it all. Thanks Delta airlines!"

Pros: "The gate agents were friendly and made the boarding process quick."
Cons: "This was my connecting flight, and also left late. I can't really rate the crew on either flight, because I didn't see them. It's also impossible for me to rate the food/beverage service, because there was none. I spent over 3 hours on planes, and no beverage service was provided. If you have connecting flights, are flying for business, or don't pack your own refreshments assuming that something standard services will be, well, standard, Delta is probably not who you want to fly with. I work in the industry and sm usually not this brutally honest, but the whole trip was pretty disappointing."

Pros: "Overall, the flight was good. It actually wasn't a Delta flight but an Alaska Airlines flight."
Cons: "The aircraft was new model 737-800, very nice! Except the seats are a bit hard. Not good for a 5 hour flight. What really made me angry is I paid for a Delta flight. What difference does it make!? On long Delta flights, you get a meal (you pay for it in the cost of your ticket), but I was put on an Alaska Airlines flight where the meals are $7.50! I think that if Delta puts you on an affiliated airline, they should pick up the tab for the meal. Entertainment is via your smartphone. Don't have a smartphone, no problem, cough up $10 for a 2 bit tablet to watch a movie!"

Pros: "Crew was upfront about mechanical issues. Did change to a different plane which was reassuring. Crew was friendly and brought snacks to delayed passengers."
Cons: "We boarded the plane with known mechanical problems. Had to deplane and were delayed 1.5 hours. Probably shouldn't say that they hope we had a nice flight. 1.5 hour delay on a 2.3 hour slight is significant, especially when we landed after midnight."

Pros: "I fly several times a year. I usually fly Southwest, I've never been happy with my experience with them. Delta has great customer service that makes me feel that I"m important to them. The flight attendants are very friendly, helpful, and genuine. It"s a nice added touch when the pilot stands there and greets the passangers. If I have a choice, I will never fly with any other airlines."

Pros: "Nothing"
Cons: "Everything"

Pros: "On time. Came around with water often."
Cons: "Just said we were being served a meal on my ticket and we didn't get one. Probably just as well since it was a turbulent take off and landing :-)"

Pros: "Crew was efficient and pleasant making for a good experience."
Cons: "Nothing"

Pros: "Crew was amazing. Seats were comfo"

Pros: "We landed safely; Beautiful infotainment screen that did NOT work"
Cons: "Extreme delays; Beautiful infotainment screen that did NOT work; Sitting on the runway/tarmac for hours"

Cons: "Flights had to be changed due to a delay on first flight that would make it impossible to take the connecting flight. My route and airlines were completely changed, which caused a big delay in original arrival time. In addition to that, my luggage did not make it and I'm still waiting to find out where my suitcases are. Very disappointed."

Pros: "On time and the staff was great"
Cons: "Nothing"

Cons: "Not enough time in London to change planes. We missed the flight"

Pros: "Crew made a special effort to find me a nondairy meal (which I had neglected to request)."
Cons: "Web page dysfunction meant we couldn't sign up for wifi. The page asked me to set security questions but the pulldown for the questions had no options to select from. I tried on multiple devices/browsers."

Pros: "The one flight attendant that realized how shitty of a situation they placed me in."
Cons: "American Airlines made me take all clothes out of carry-on, took my brand new AWAY bags, and made me stuff my clothes and other belongings into 5 plastic bags. All because they said my bag was illegal to fly on plane (whether it was checked in or not). Turns out they didn’t have to do that. What a crock."

Pros: "seats comfy, seemed like a newer plane, crew was lovely."
Cons: "usual complaints about domestic flights - not having free headphones and not having free snacks."

Pros: "Everything"
Cons: "Middle seat"

Cons: "Luggage allowance policy was not clear, so that they can try to charge passengers extra fee. Airline blames on one another when it comes to connecting flight if we purchased a one stop flight"

Pros: "Cabin crew attentive. Comfortable seat. Only 2/3 full. Easy boarding and embarking. Overall, value for cost."
Cons: "Food. No individual entertainment unit."

Cons: "It was advertised that one can see entertainment through WIFi, but from my iPad, i can't connect to this WiFi. I tried several times until I just gave up."

Pros: "I would like if for my return from Paris to Chicago, Chicago Seattle I would be greeted by the personal and offered to flight first class without extra charge to compensate for the bad experience on my way going in. Thank you"
Cons: "I was told I would be able to choose the seats only 24 hours before the flight by going online. I tried to choose the seats online but could not have access to the site. I then called the number provided to ask for more help, and was told that I could then only choose the seats at the check in time. I was at the airport 2 hours before the flight schedule to book my seat and was told them that I could only choose the seats at the gate. Once I got at the gate I asked the person to please give me a seat at the aisle for medical reasons but after waiting until the boarding process had started I was giving a middle seat. Not only I was treated as a stand by passenger that had not purchased the tickets I was put nt on group 8 and at the moment of boarding the gate personal aggressively grabbed my carry-on bag because they insisted there was no more spaces in the compartment above heads. Once I got inside of airplane I saw many empty compartments available for carry-on luggage. I wish I had not purchased my ticket with Iberia Airlines operated by American Airlines. It was not a good, pleasant experience and do not recommend. I wil certainly avoid in the future and not travel this way another time. Thanks"

Cons: "No food or entertainment offered at all - for a 5-1/2 hour flight. Seats uncomfortable. I don't like how it feels like you're nickle and diming us - charging for every little thing, including what seat you sit in."

Pros: "This airlines sucksI didn't really like much of anything about the entire trip"
Cons: "I didn't really like much of anything about the entire trip. Mainly, there was absolutely no entertainment except some overhead movie that no one wanted to watch. The plane was old and comfortable."

Pros: "Everything was on time!"

Pros: "loved having a movie to pass the time. Super friendly attendants."

Cons: "I paid for a non-stop from Seattle to Philadelphia. they cancelled it and only had options that dragged out the trip, caused an extra day of lost work. There was no attempt or offer to ameliorate the inconvenience, or refund the cost -- even an upgrade would have been appreciated. just here's what we have, take it or leave it. I am through with American"

Cons: "No screens, no wifi"

Pros: "Really? I just gave 1 star. Your feedback form should be smart enough to realize that."
Cons: "It's not finnair. It's American Airlines. The sears were so cramped that I have a horrible backache. Stop calling it finnair. Several airlines booked tickets on this flight. There's nothing good to say."

Pros: "Flight was ok, staff was professional and friendly. A good cleaning would be great. I'm average height and light build for a woman but I find the seats really are snugger than ever."
Cons: "AA didn't notify me of their change to my itinerary so I missed my flight, they cancelled my return flight from Europe, and only offered to refund my ticket when I spoke to a supervisor. I drove 5.5 hours to another city to catch a flight to Europe, believing my return ticket was valid as AA first told me, only later to learn they cancelled it. Thanks to AA, I currently I have no return ticket. Others on this flight and on my later Iberia flight were cursing AA loudly so I don't think my issue is an anomaly, but is more likely AA's new standard of conduct."

Cons: "Self check-in staff at Seattle was not that helpful."

Pros: "Crew were friendly"
Cons: "Ac was broke on plane, no wifi or entertainment options, lots and lots of being kept in the dark waiting and waiting after already boarding the plane or landing on the runway"

Pros: "Kind and attentive crew"
Cons: "Was a bit delayed"

Cons: "Your plane needs outlets to charge electronics. Unless your gonna show movies on your flights, ppl need a way to entertain themselves for the flight. If they burn through all their battery power, it's an inconvenience to try to charge it in the airport when they land. All of the outlet Chargers in Chicago, Seattle and Philly were broke as well. The U tied wing was amazing. Your prices are great but to keep ppl from rather paying more just for one or two more luxuries, try fixing this."

Cons: "The flight being delayed & then cancelled at the last second"

Pros: "The flight overall because we arrived early."
Cons: "The fact that we were on the plane and was not allowed to enjoy the entertainment as I did with my flight to Seattle."

Pros: "Entertainment"
Cons: "Too many levels of passengers"

Pros: "Very efficient boarding, comfortable coach seats, good crew"
Cons: "No food! except pretzels and sandwiches for purchase. I didn't purchase a sandwich but the two guys next to me did and were both vocal about their disappointment with what they received for $9. And they were strangers who didn't talk to each other the rest of the time, so I think they meant it. Also, entertainment: they had a movie on the pop-down screens, and 4 free movies to stream to your device using onboard wifi, as well as 2 tv shows. So maybe I'm being harsh. But it was a transcontinental flight and they didn't have headrest screens loaded with movies. Is this only for international flights? The movies were bad, or at least not appealing to me ('Keanu' and 'Zoolander 2'). It was possible to pay for additional movies, but who wants to do that? It was sort of the EasyJet model, where you get good basic service but pay for everything additional that one gets for free on Delta. Maybe that was reflected in the price I paid for the ticket, but I was expecting that AA would be in the same league as United and Delta. One nice perk: free wifi for T-Mobile customers, including me."

Pros: "It was very inexpensive and on time. And it was much more comfortable than those budget airlines like Spirit, Frontier, etc."
Cons: "The snack choice was unappealing."

Pros: "On time. No issues. The last two times I have flown Delta I've had issues. Smooth sailing"

Pros: "arrived alive"
Cons: "If you're remotely claustrophobic this is not the flight or aircraft you want to be in. When the flight was booked and paid for I was under the impression that I would have a seat on the plane. As it turned out in order to board the plane I had to pay extra to secure a seat. If this is not a "bait and switch" operation I don't know what would qualify."

Pros: "On time. Friendly crew. Good price."

Pros: "AA has been good to me--- Gold card a big help."
Cons: "The LAX concourse could at least 2 more coffee shops in addition to Starbucks.The wait was 40 minutes at Starbucks to get a cup of coffee!!! Get on the ball LAX!! We need our caffine in the morning."

Pros: "They switched my flight promptly when I missed my connection."
Cons: "I missed my connection for no apparent reasons. When asked for compensation they said there was nothing they could do and cited reasons Regarding the boarding and deboarding of a special needs passenger."

Pros: "Claudia was wonderful, I would love for more flight attendants to have her cheerful attitude."
Cons: "My snack was mini pretzels"

Cons: "I would not change a thing the flight was wonderful and the stewardess Virginia great"

Pros: "Seats were fairly comfortable"
Cons: "No in flight movie"

Pros: "Flight was on time. Bags didn't get lost. Pilot and crew seemed nice."
Cons: "Smallest middle seat I've ever sat in. Wifi was $40. Baggage Fees were pricey. No free snacks. No free entertainment options."

Pros: "I know AA and Alask are same company but I bought Alaska ariline ticket and everything I need to deal with is AA. It's too confusing."
Cons: "Too confused!"

Pros: "There was enough space between the passengers and for my legs."
Cons: "To many layovers. The should arrange for more direct flights. Having less options but a reduce flight time will be best. That goes for all airlines."

Pros: "Not much"
Cons: "We sat on the tarmac for an hour after we landed. Missed my connection, no other flights that night. It wasn't even 10 pm yet."

Cons: "Our flight from Seattle to JFK was delayed over 11 hours, not because of weather or mechanical issue, but because a flight attendant fell ill and American Airlines had no one to take his or her place. They had to fly in an employee from Texas to cover the shift. Are you kidding me? I understand there are unforeseen events but any reputable airline should have a personnel contingency plan better than that. As a result, we lost a whole day of our vacation, missed our Broadway performance, and others missed their business meetings. All the alerts informing us of the delay were sent long after they already occurred. I will avoid flying American again at all costs."

Pros: "Flight attendants and boarding personnel are very friendly."
Cons: "Mediocre food and entertainment. Internet price are ridiculous compared to competitors ( just flew SouthWest - so much better). Cost at about $6 for a half-hour. They had to bring the cleaning crew back on to clean parts of the plane - it was to dirty for anyone to sit in one row."

Pros: "The captain of the plane did a phenomenonal job communicating with the passengers on board. He provided us information on location, altitude, and let us know when to expect turbulence which I thought was great, as many do not communicate much with the passengers. Also the plane was in good conditions and was comfortable."

Pros: "relatively quiet for a redeye, seats were made out of a decent leather like material, TVs in the back of each seat along with charging inputs"
Cons: "AA version of the 737 is very cramped, small seats with little room and very upright, barely recline if at all. Also, unlike other airlines they installed metal boxes underneath the seats for the life vests which take up a third of your leg room. Overhead air barely blows and the overall temp was a little too warm for comfort even while just wearing shorts and a T-shirt. Lights were bright for first half of the trip until they finished drink service even though flight started at midnight."

Pros: "There isn't much to like about a red eye flight. It got us home. We selected it based on price and schedule."
Cons: "Crew made one pass thru cabin with a mini bag of pretzels and one pass thru with beverage. Never saw them again but perhaps that is the norm for AA. No so with other carriers we have flown red eyes on. Always tough getting a good connection when flying west to east"

Pros: "Everyone from the woman checking boarding passes at the gate to the pilot himself, was friendly, jovial, and light. Very relaxing trip, I just felt very welcome by everyone."
Cons: "Nothing at all. Well, it'd be nice if ALL seats were 1st class size, lol."

Pros: "nothing"
Cons: "flight was delayed. long overlay. uncomfortable plane from lac to fat."

Pros: "Delays"
Cons: "Delays"

Pros: "Nice plane."
Cons: "WAY too hot."

Cons: "Took forever to board"

Pros: "We did not make it to this flight since it was cancelled"
Cons: "We were rebooked on a flight with a short connection to London and they bumped us off that flight claiming that they could not get our bags in on time. Very poor customer service."

Cons: "See above."

Pros: "The bad stuff overshadowed the good stuff. Bad experience."
Cons: "We took off late and never made up for the time lost which resulted in me missing my connection in Denver. Had to be rerouted to Toronto that night and spent night in hotel. Next day, we took off late and that resulted in me missing my connection in Denver... It took me two days instead of one to travel to my last destination. Not happy with Air Canada, three out four flights took off late. I also almost missed my flight in Montreal to go to Paris if it was not for the friendly and helpful Canadian Customs people."

Pros: "On time and efficient"
Cons: "To pay American dollars for baggage on AC coming back to CANADA or to pay AT ALL for a bag"

Cons: "Most uncomfortable seating that one can have. I will never fly rouge again."

Cons: "Unhelpful crew,dreadful status updates about our delay, not enough food on board for everybody"

Pros: "Smooth flight and we arrived ahead of schedule"
Cons: "I as first time travel from US to Canada no information given on flight regarding how to get to connections and customs. Unaware of requirements to claim luggage after customs and before security We were surprised at the lack of any offer of snacks on a five hour flight"

Cons: "movie selection is poor and using your own device isnt that enjoyable. Girl at counter was demeaning."

Cons: "That was a first time i saw a paid entertainment system. That was a long-haul (9 hrs) flight. Either you pay and have an iPad with movies, music etc. or nothing. Very interesting."

Pros: "Staff"
Cons: "Food and no tv on the seat didn't want to look own the whole time"

Pros: "When I had to reschedule they were very nice about making sure that I had the information I needed and they gave me great seats on the way to London."
Cons: "My flight was Delayed and I had to reschedule that was unfortunate."

Pros: "The crew was amazing"
Cons: "Nothing"

Pros: "Crew was nice though not very professional."
Cons: "Airplane quality Seat dimensions Food quality Allowing passengers to sit where they pleased Pay for food- embarrassing"

Cons: "Always delayed."

Pros: "Good selection of TV and film's"

Pros: "The crew was very friendly."
Cons: "The plane boarded early and the food was not good. The pasta was over cooked and essentially a mash."

Pros: "Crew was great!"
Cons: "Why is there no TV?"

Pros: "Food and comfort were okay."
Cons: "My first plane sat on the Tarmac for 45 min, thus I missed my flight to"

Cons: "Flight was delayed so badly that I missed my connection to Paris and arrived a day late, which was NOT nice."

Pros: "People were helpful & friendly"
Cons: "Timing between flights was not enough to make connection. Had to take next available flight."

Pros: "Aircrafts decent legroom, flight on time"
Cons: "Food"

Pros: "Nothing"
Cons: "Worst flight ever. Had a technical difficulties 3 times in a row. Had to be cancelled and put on the next day and again same thing over and over. So missed all my connections. Cut short my vacation. Will never flight air Canada again."

Pros: "That the plane didn't crash."
Cons: "When I flew to Toronto the plane left 15 mins late but arrived an hour an twenty min late. No turbulence or trouble, just late. I stepped off that plane to my connector to Paris when boarding was suppose to start but that plane was on an hour delay. The food is just horrible, anyone who has flown knows this, and on both flights first class was the only priority. They got to everyone else when it was convenient. This was my first time flying with Air Canada and will certainly be my last. I'll happily pay a little more for the other airlines. So if you fly with them, good luck to you."

Cons: "The waiting room in Boston was awful and behind security, hot, small crowded. Delayed"

Pros: "Flight crew was friendly."
Cons: "Horrible smelly crampy cloth seats, awful food, they don't offer complementary wine and beer for international flights like other carriers, no tvs in the headrest. The flight crew works slower then I have ever observed in my over 200 flights. Took them 1hr 40min to serve what they called "dinner", Delta and others knocks it out in 30!!! And don't get thirsty, You'll die of dehydration before you get a drop of water. They treat ice like its gold. 2 cubes for each drink. If u ask for more u get one more cube. Lol. It was just a horrible experience! I will never fly Air Canada again."

Pros: "I liked the comfort and the service"
Cons: "the long delay in Montreal"

Pros: "Check in and boarding process ok."
Cons: "Had to buy meal on the SFO-Montreal leg, which was at the snack/wrap level. Constraint space seats."

Cons: "Deplaning and entering the terminal was delayed substantially."

Pros: "Flight wasn't full so could spread out a bit"
Cons: "No entertainment unless you had your own device"

Pros: "Never flown "air canada", was a bit apprehensive. But I was very much happy & pleasantly surprised!"

Cons: "5 hour delay. Didn't get the correct seat."

Cons: "Long time till take off."

Pros: "the crew was great, food was alright, and overall I enjoyed my flight"

Pros: "The flight was comfortable. Entertainment choices were varied and generous."
Cons: "o'Hare needs an upgrade."

Pros: "Nothing"
Cons: "When I arrived in London my bag was not on carousel. I went to help desk to find out my bag was put on the next flight for some reason. No explanation given and no real accommodation given except telling when the flight would arrive. I guess I luckily only had to wait an hour, however it shouldn't be that way to begin with."

Cons: "Was a bit of a pain when I wanted to simply get off the plane in Geneva since it would be shorter, but then the plane was late, but that can't be helped"

Pros: "Nothing"
Cons: "first flight cancelled, second flight delayed so impossible to get the connection. Nobody called me about it, I had to go to ask."

Pros: "Some of the members of the crew were so nice"
Cons: "SFO to Montreal: no complimentary food; not even nuts. I was forced to check in my bag because it wouldn't fit in the tiny sizer."

Pros: "Nice crew,moving all the time, food was good."
Cons: "A little bit colder than I expected."

Pros: "Boarding early"
Cons: "Leg room was not good"

Cons: "The seat I sat in felt lumpy. Its also always so loud in the smaller planes, but I knew that."

Pros: "Great service"

Pros: "Super polite crew"

Pros: "I was landing in Montreal around 2am and my next flight wasn't until 18 hours later. I talked to the crew about suggestions for finding food, a good place to wait, and suggestions for seeing the city. They were fantastic. Suggested the 747 bus so I could see Montreal and helped point me in the right direction for where to be comfortable as I waited for the city to wake up. Thank you all so much!!"

Pros: "Every thing"

Pros: "This was the greatest flying experience I've had in a long time. The crew was very pleasant and helpful. The in flight entertainment was spot on and the food was delicious. I would definitely recommend them to anyone flying abroad. They were efficient in the boarding process as well. I will be flying them again!"

Cons: "Entertainment doesn't work with Android 8.0 devices because you decided not to support newer versions? Stop restricting it to higher versions idiots"

Pros: "Nice attendant, food OK, no delay."
Cons: "Internet costs"

Pros: "And it was actually terrific. United employees were top shelf at every stop, on every plane. (I did seven flights total.)"

Pros: "Not anything in particular, this was a pretty aweful flight. They at least gave out connection flight information and told passengers which flights would be missed and set those people up in hotels."
Cons: "Plane was fully boarded and as the crew was preparing the cabin, the pilot realized there was a mechanical issue. An hour and half of sitting on the plane with few updates and grumpy people and crew, air being turned on and off as they fixed the issue and no indication when we would actually take off. They should have offered some water and snacks at least and gave more frequent and better updates."

Cons: "Shitty service ,...."

Cons: "Majorly delayed, barely made my connecting flight, My poor body was so confused - "WHY are we up right now, WHY are we running so hard and carrying much weight." I felt exactly like I was finishing a cross country race trying to make my connection, then the gate agents made me check my bags, I'm looking at completely vacant overhead compartments and will never fly this airline ever again. No food. No drinks. Rude and disriptive attendants - let us sleep!"

Pros: "It was great!"

Pros: "View"
Cons: "Over an hour delay"

Cons: "The seating was the worst I've ever had in my life and I've traveled my whole life. After I finish this trip I will never take United again. Everything else was wonderful"

Cons: "The flight was canceled because of the weather and then I have to wait more hours in the airport for the next flight.."

Cons: "Did not make connection due to flight being late"

Pros: "Sat by united pilot who was just on flight to go to training and was with my 10 mo old daughter and was absolutley wonderful, so helpful and Im sure it was not an ideal situation for him. On second flight we sat next to flight attendant and a trainee and made our first flight trip... that could have been awful great! Big thanks to all the staff."

Pros: "Smooth flight"
Cons: "No problems"

Cons: "The gang stalkers that Kayak and United let sit next to me."

Pros: "The price was cheaper than the other airlines. The flight itself was pretty smooth with very little turbulence."
Cons: "The seats were uncomfortable, and the coffee was way too strong, and there was no Splenda, only Equal, which contrary to the flight attendant's knowledge is NOT "the same thing." United provides only 1 cheap sugary snack for the whole 5 hour flight. Couldn't get my phone to connect to the internet b/c I didn't have my United Mileage plan number written down or recorded anywhere, and I didn't have the card with me. To top it off, there was a screaming toddler in the next aisle over."

Pros: "Rhe food"
Cons: "Custmer Service"

Cons: "The seats and headrests in particular were most uncomfortable for a 4+ hour flight. I was most uncomfortable on the flight and ended up with a pain in the neck!"

Cons: "I'm a normal sized man and the seats were terribly cramped. I likely won't fly United again as long as I have a choice."

Pros: "On time."
Cons: "New looking plane but the TVs behind all the chairs were locked without a credit card. The new chairs looked great until you sat in them. I'm 5'10" and my knees were already brushing up against the seatback in front of me. If you push the recline button on the armrest, the chair doesn't go back (of course it doesn't, the person's legs behind me are probably up against my chair anyway). Multiple people around me were also asking around if the chairs recline. I have a mild back injury and sitting up at 90 degrees the entire way was very uncomfortable."

Pros: "I liked the legroom of Economy Plus. The flight itself was good. Didn't buy any food."
Cons: "We arrived late in Denver and had to sit at the gate and wait for the jetway person to arrive and connect the jetway to the plane. I also didn't like the fact that I had to buy Economy Plus because my wife and I were not only not assigned seats together after booking, we were not assigned seats at all. When I booked the flights I was only allowed to choose seats for the first flight - Charlotte to Houston...but not for the other three legs of our Charlotte to Seattle trip. The only two seats together from Houston to Seattle were in the very last row. And, on our return flight we had to purchase Economy Plus in order to sit together."

Pros: "Changed my seat to a better one"
Cons: "Plane an hour late taking off"

Pros: "More important than the trip home last Wednesday was the reason for the trip. We attended my granddaughter's wedding. Everything else was secondary. Even if the trip had been in a one wheeled barrow, it would have been good. To get to what you want which is the mechanics of the trip. The two people who attended to the aisle chair, most teams were competent. Some hadn't done many passengers so they were fumbling with the straps. I've learned that I almost alway have to ask for one at the gate where they check or issue, (what's it called, loading permits, some kind of pass, not landing pass. loading pass. I can't remember and my wife has gone to bed.) Well, they have to come up with an aisle chair because I've only got 1 1/2 legs. I always make it to the seat on the plane, but the competency of the various crews is uneen. Sorry my answer is so nonspecific but I don't remember one airline from another. Great people all, get the job done."
Cons: "Not much I don't like. They get us there That is the main thing. Sometimes when the plane stops after it has pulled away from the Jet Way, the pilot gives an explanation that I find unfulfilling, not enough details. I suppose if they explained more, other fliers would find the explanation too verbose. I can live with it. Again this is about all flights and airlines. Nothing stands out, such as, " this awful thing happened when we left San Francisco.""

Pros: "I liked the crew once we were on the plane"
Cons: "The plane was full and we were on basic economy. The folks at the gate were rude and unhelpful, at the United kiosk the personnel were openly hostile. Thank goodness the crew treated us with some decency and were very nice."

Pros: "Flight was smooth and on time"
Cons: "The boarding gate attendants were rude and uncaring when we asked them to help us switch pre-assigned seats to ensure our two year old sat with us. While we might have understood better had they been empathetic, they were rude and uncaring and said when you book online you sign a waiver and they can not do anything about this. Wow. This was our flight back. Originally on the way to our destination we had used Delta and that customer service experience was completely different even though that flight was full too. Never flying United again as long as I can avoid it."

Cons: "Sitting on runway for almost an hour bc of ground stop in San Francisco"

Pros: "Great flight with very nice amenities"
Cons: "Seat did not recline so made the flight a very sore lower back experience."

Pros: "We got there on time!"
Cons: "In flight entertainment worked fine at first but then, halfway through my movie, it just kept stopping and trying to buffer. I tried to reboot my device, reset internet connections, restart the app, but nothing worked. Even though I had 40 minutes left in the movie and 90 minutes left on my flight, I couldn't finish the movie."

Pros: "Left on time."

Pros: "Getting off the plane"
Cons: "Everything was cramped- not enough space to move. They completely ran out of overhead space. Completely crazy"

Cons: "One of the crew members was late to arrive, so boarding was delayed. However, The gate crew was amazing, very communicative and apologetic. During the flight the attendants seemed very agitated, I think a smile would go along way to improve the attitude of everyone. I also work with the public, I get that it is challenging, but I do believe that the simple gesture of a smile sets the tone."

Pros: "Everything"

Pros: "Cramped seatting, minimal food or beverage options and we were invited to provide our own entertainment. Pretty typical flight for ten or fifteen years ago. The crew was extremely pleasant. Very surprising and maybe the only saving grace."
Cons: "The airline is clearly trying to maximize profits by squeezing any comfort from the plane while still charging ludicrous amounts. Good for them. That's their free market choice. But do not then be startled that everyone is angry before, during, and after your flights. In the long run that's how you shed customers."

Cons: "Gate attendant recommended we check bags because overheads were full, but there were multiple empty overheads when we entered. This caused us an extra delay when we landed."

Pros: "The flight"
Cons: "The time"

Pros: "Crew was very kind, helpful, and informative."
Cons: "Outlet doesn't have USB slot for charging. No TV screens for the seats on the flight."

Cons: "The leg room was abysmal."

Pros: "Nice employees."
Cons: "Four hour delay, caused missed connection. Had a 3 hour plus layover but not long enough. 17 hours SEA to LAX. Not sure there won't be more delays."

Pros: "The staff on the flight was great! They treated us like family. Great job. United Airlines."

Cons: "Wish the free in flight entertainment was available on the United app for this flight"

Pros: "When it was over."
Cons: "Had to wait, probably 5 minutes, while holding my bags right outside the plane for an employee to do something. The attendants were unfriendly, unknowledgeable, and not available. Crammed 3 of us in the seat before emergency exit row seats, about 1" from my knee to back of seat in front of me and a 90 degree angle back, although there were many, many rows with only 1 person in them. One woman had enough room to stretch out and sleep across all 3 seats. Our seats didn't recline but the row in front of us did which made it even more cramped. Tried to ask attendant to move but couldn't find one for over an hour. Tried to ask an attendant but he just walked by me. Pushed call button and he says oh you want to move? There's​ a seat over here, before I could see where, he walked away. Moved myself to a row with 1 other person who was angry she now had to share "her" 3 seats. She typed angrily all flight and kept putting her legs and personal items as close to me as possible. She used both trays to hold her laptop and spread herself out so I'd be uncomfortable. Could've been prevented if the attendant had talked to the woman first then moved me. Had to wait when getting my drink because the attendant turned to help others, 4 times, after she'd already asked me what I wanted. She got food for someone while I waited. She made change for someone while I waited. She walked away to do something for someone while I waited. She served someone else while I waited. Asked attendant where the electric plug in was and she said the plane didn't have one, I said the sticker says the plane does, she walked away. Worst experience ever. Won't fly this airline again because of this experience."

Pros: "EXCELLENT"

Pros: "Crew was very pleasant and helpful. Comfort is OK but that's because we shelled out $35 per seat extra."

Pros: "Nothing"
Cons: "Everything the customer service reps were very rude and condescending. United is awful I'm not sure how they are still in business. The rep refused to help me because she was getting off in 10 mins."

Pros: "Very nice and flexible people and boarding was easy. Smooth flight."
Cons: "Very cramped tight seating and the stewardesses were a little lax. Also, the overhead speaker was not loud enough to hear if you're sitting by the window as I was. They have no control over turning it up and if there was something to do with safety I would be in trouble."

Pros: "Flight was on time and boarding was smooth"
Cons: "Full plane it felled very cramped."

Pros: "Blankets were provided"
Cons: "There wasn't any food or entrainment for me to rate."

Cons: "The worst part was the new seats are the smallest ever. I could not sit without my knees jammed into the seat in front of me, and on both legs, Ithe seats were narrow that the people next to me and I were overlapping shoulders - that was a first. Unless its flights in the future are significantly advantageous, United's losing my business. It's not worth saving a few bucks to me to be so uncomfortable."

Cons: "Could not get seat assignment 24 hrs in advance. Website said see desk. Phone call to United said pay more $ get a seat. Had to check in twice, once with bags...still no seat...wait in line again at gate for seat."

Pros: "We incountered quite a bit of turbulence. The captain kept us informed and did his very best to assure a smooth flight."
Cons: "Can't complain."

Cons: "was more than 4 hour delayed"
