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."
Cons: "Filthy plane, and delayed too long"
Pros: "Crew was very friendly and efficient. Flight was pretty smooth."
Cons: "On time departure would have been nice. 2.5 hours late."
Pros: "Use my built up miles for the SEA-ANC leg of our trip, as to physically price it out as one ticket usually increases the fare by 300-600 u$d depending upon time of year. As it was the tail end of an already long journey (OKA-ICN/ICN-SEA), booked the First Class Cabin. Every mile was worth it."
Cons: "N/A"
Pros: "Never made the connecting flight."
Pros: "The crew really kept us updated on the many delays."
Cons: "There were SO many delays and they kept changing. At one point we got on and off the plane."

Last time flying Delta."
Cons: "Missed connecting flight because the first flight was delayed by 2.5 hours. I didn’t get the comfort seat I paid for because of this and was not given a refund for it."
Pros: "Crew"
Cons: "Food, cramped seating."
Pros: "Great flight attendants and crew, 30 min early!!"

Pros: "Almonds"
Cons: "Seat, did not get upgraded"
Pros: "Great service, very comfortable."
Cons: "Too crowded."
Pros: "The flight was fine, attendants we're good, entertainment options are great."
Cons: "Boarding. It was probably the worst I've seen. A shared intercom system between two gates (b7 and b7a), boarding flights around the same time and our flight beginning portions of pre boarding with no announcements caused mass confusion. Passengers lining up to go before they should, bumping into each other, no info or corrections over the intercom. The gate agent yelling at people to move aside. Overall terrible gate agents and terrible set up. Flight crew was great though."
Pros: "Free entertainment and free food was unexpected and very welcomed, especially given the trend of charging for more and more features."
Cons: "The tsa is worthless"
Cons: "*Again, my first choice of main off the menu, in Delta One, had run out. *Not a fan of the Delta One seats."
Cons: "The air conditioning was broken so it was sweltering the whole time. Staff didn't even mention it or apologize. No leg room. Bags took longer than 20 minutes to arrive but we didn't make a fuss since we were just glad to be finished with Delta. I'll never fly Delta again even if it costs me more."
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."
Cons: "ran out of the food i wanted. poor selection of food... screen on "tv" was too dark to see details"
Pros: "Nice, normal flight."
Cons: "Pilots not there on time, arrived perhaps 30 minutes late, didn’t say why."
Pros: "No complaints about the flight or the crew."
Cons: "Delayed repeatedly. 3 hours behind schedule and no clear explanation was offered."
Cons: "All went well."
Pros: "seat was comfortable, crew was kind"
Cons: "screaming child"
Cons: "Almost a 5 hr flight and there was no food or snacks given and water by request only. It was a full flight and the crew had just an attitude. Never had a flight like this one before. Horrible just horrible"
Cons: "The fact that United forces basic economy customers to check carry-on luggage is nothing but a cash grab. Some of the overhead compartments were completely empty yet they force you to pay ?30/ bag. They also gouge you an extra $25 per bag if you bring your carry on to the gate."
Cons: "Delta Global Services is the contract company for UA and Delta in MISSOULA. After a great flight to MSO from Denver, we have been sitting in the plane while DGS tried to figure out how to get us off the plane. No management is here to make decisions. Horrible company that is managing United’s flight"
Pros: "Staff was professional"
Cons: "Flight was delayed 50 minutes"
Pros: "XSS"
Cons: "XSS"
Pros: "XSS"
Cons: "XSS"
Pros: "XSS"
Cons: "XSS"
Pros: "Cabin crew was very efficient and polite"
Cons: "Baggage folks were not helpful towards anyone. There were a lot of problems and the agents seem to just ignored most everyone."
Pros: "The boarding was quick and the flight was on time. The crew was courteous."
Cons: "I selected economy comfort in the kayak app, but when I called about my boarding pass, kayak said they only sell basic economy. What did I buy? UAL only sells a limited selection of overpriced food. There is no music and you have to pay to see the flight map."
Cons: "We missed the whole vacation due to United flt. 599 being late into SFO. We missed the Zurich flight by 7 minutes due to a mechanical issue (overhead bin lid would not stay closed.) United customer service was very poor and after 16 hrs. at SO without resolution on flights and schedule, we just came back home. If Siss Air could have waited 10 minutes for 12 or more passengers, we would have been fine. I don't know if United communicated with them or not. This was a disaster!"
Pros: "*"
Pros: "at check in - check baggage was quickly serviced"
Pros: "Paying for $1200+ for an 8 hour flight to Guam and all the crew fed us was coffee and water plus pretzels. Oh yeah have to pay for a real meal"
Cons: "5 minutes early arrival time."
Cons: "My only real issue was that, upon checking in online, I was informed that my boarding pass would be emailed to me. I don't believe it ever was. I checked all of my various email folders, including spam, and saw nothing."
Pros: "Gates for connecting were close and even with delay, I made it on time."
Cons: "Flight delay, that made the short connection even shorter"
Pros: "Poor internet going. No internet or streaming returning."
Cons: "Poor internet going. No internet or streaming returning."
Cons: "Gate crew didn't help much with seating or connecting flights. Staff almost never smiled, and when boarding the plane instead of a, "hello" or "good morning", there were two attendants staring at their phones. They looked up when I greeted first, but seemed put off a touch. They also switched the seating without telling us ahead of time, so my husband and I had to sit in middle seats, apart from each other on our anniversary trip. Very unhelpful and unfriendly when I inquired to change."
Pros: "On time, courtesy"
Cons: "Seating space, cramped"
Pros: "Screens at every seat, but mine was broken and so were several around me."
Cons: "No power outlets at my seat. No free chat. Wifi should come as part of the ticket price. I feel nickel and dimed and I am tired of it."
Pros: "Quick and friendly staff"
Cons: "Uncomfortable seating"
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: "Now Sherry in any documentation I received did it say that my flight was operated by United airlines. I waited at ANA check in until within the 2 hour window and went around and asked someone at United who confirmed that they were partners with ANA."
Cons: "The flight was canceled because of the weather and then I have to wait more hours in the airport for the next flight.."
Pros: "Smooth flight"
Cons: "No problems"
Cons: "flight control forced us to miss my connection to Kansas City so had to spend $150 on a hotel in San Francisco and wait an entire day to get home."
Pros: "This new ticket where you have basic economy and pay for everything is ridiculous. You can't take a high end airlines and make it a basic economy people don't like that. Is this the worse version of Spirit airlines?"
Cons: "Just feels Cheap. Baggage claim took forever"
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!"
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."
Cons: "Delayed getting on our way I think because they were late getting in and had to do all the plane checking. Captain said safety checks. Seat space felt tight and I am short."
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: "The flight attendants were nice and helpful"
Cons: "Got a migraine because two ladies sprayed perfume"
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: "Nothing"
Cons: "Will NEVER fly United again. Going home to advise EVERYONE I know not to fly United. They straight suck. Starving people on long flights with hot food for a third of the plane?!?!?! Then telling me I'm wrong for expecting a meal on an almost 7 hour flight?!?!?! &, even better, the reason my son & I starved all morning, day , & evening because EVERY single flight (all 3) were late, one so much so that we almost missed the connecting flight. Wow, is all I can say. After I still have United a chance after assaulting that poor man. Beyond highly disappointed."
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: "Good flight and good crew."
Pros: "Boarding. Took off early and landed early"
Cons: "Everything else. Seats were uncomfortable. One crew member smelled of some nasty perfume that burned my eyes and nose when she bumped her way down the aisle. Ground crew was rude at check in. Mischarged me for baggage. No entertainment on my ipad. Noisy."
Pros: "Boeing planes are very comfortable. No pressure Really nice experience"
Pros: "Nothing"
Cons: "Customer service at united was rude on all ends phone and counter. Plane was delayed five different times and delayed for both flights. still at airport actually waiting on plane to take off when it was suppose to at 834 pm now it's 1142 pm so three hours later. I don't know who is running united airlines but it's a joke and should be shut down. There is so many people upset right now, horrible airlines."
Pros: "Fast clean boarding and unboarding."
Cons: "Missed the fact that I selected a red eye flight with a three an a half layover"
Pros: "Flight attendants were good. Pilot kept folks updated when there was an initial delay."
Cons: "Seats on United seem to be even smaller than other carriers. I'm 5'5'' and 110 lbs and I was still quite cramped."
Pros: "Good flight, good crew"
Cons: "People in group 5 don't have a chance to get their carry in bags in the over head storage."
Pros: "Nothing."
Cons: "No alternative options given. Slow response. No retrieval of email confirmation after purchase of trip. Flight was delayed and no notice was given. Rental car had to ordered last minute and was left without room and board for the night. Had to call again for actual co formation of second flight because no notice was given,"
Pros: "My other passengers in First Class. Your crew was also very kind and well mannered."
Cons: "I spent over 150 for an upgrade for a red eye for a flight I already spent over 500. Your crew lacked attention in service and one specific crew member (male) woke me up twice due to the loudness of his voice. Disappointed in the quality for the amount spent."
Cons: "Had to sprint through the airport to make a connection because the flight was delayed and then went to a gate in the international terminal which was far across the airport from my connection."
