Cons: "Everything was disappointing"
Pros: "Everything was fine except the flight delays"

Pros: "Confi and relaxed atmosphere"
Pros: "its a five stars trip in its services"

All the middle East airport has some inconvenient they built good airport but important is mixed and there should be protest international for travel convenient"
Cons: "There is bathroom and water access in the airport"
Pros: "Crew was nice. Food was excellent."
Pros: "Food was good. Service was great. Bathrooms were clean. Refreshing experience."
Pros: "The flight was on time and boarding was fast"
Pros: "The crew was friendly"
Cons: "The security process to board the plane had no order. Stood in line while people after me was able to board the plane. When it was my turn, I was randomly selected for additional security screening."
Pros: "The crew was excellent in their mannerisms, efficiency, service and never ending smiles."
Cons: "The flight was not overly crowded and many of the passengers were seated with three people per set of seats while others were seated individually and able to spread out with much more comfort. I felt that when the flight crew saw this they could have made everyone much more comfortable by switching people to two people per row thus giving them more room especially on such a long flight."
Pros: "Great crews, excellent airplanes, wonderful in transit experince."
Cons: "In flight coach meals were average."
Pros: "Everything was great except Food and service comfort of the plane Cleanliness was superior"
Cons: "One crew member was a pain if you wanted ice you got 3 cubes ask for more he would ignore you. He was rud and nasty. I mentioned to other crew members they say just his way. If that is his way maybe he need find new job."
Pros: "I like that the air stewards bring you water and drinks throughout and don't judge you for being too thirsty. I like that they respect that it is a night flight and serve the meal quickly so it can be dark for the whole flight and you can sleep as much as you can. I like how efficient the layover is in Doha - only 40mins!"
Cons: "I don't like when they don't ask the person in front to move their chair up for the meal and the passengers have to ask each other. I don't like that they can't tell you the gate of your connecting flight and how long it will take to get you there - including if you will need to take a bus and the train. I think this could reduce a lot of anxiety. If they could do this, it would also be helpful to let people who have a connecting flight that is boarding in the next 30 mins off the plane first. This would save pushing and shoving in the aisles... and would also reduce anxiety about booking a flight with such a short layover."
Pros: "The guidence between flights I was the only person off my flight to transfer and they sill had a gal waiting to take me to the next gate"
Pros: "The leg space is what got this flight a 3 star."
Pros: "a wonderful experience to travel with Qatar airways, recommended for others as well."
Pros: "I liked the food and the entertainment ."
Cons: "My seat was broken so I sat up right for 16 hours. To top it off I needed to use the toilet REALLY bad but was denied even though we were SITTING on the runway for 20 mins. When I FINALLY get to use the toilet, after a smaller Asian girl and a taller Indian girl were getting bags of blankets out of, I leave a WOODEN CLIPBOARD full of VERY important papers that will cost me inside. Yet when I call to retrieve them they are "nowhere to be found" so you're telling me out of those 2 women, the Indian gentleman, the black woman & the other Asian woman back there didn't notice a clipboard when I was the only person back there trying to use the toilet or they simply threw a wooden and metal clipboard away ?? With what was clearly paperwork clipped onto it ? The girl at the service desk of Qatar airways claims to have looked herself. But she was rushing me off of the phone so I don't feel like she remotely cared even a little. I am PAST unhappy. So thank you for throwing my paperwork away I know for sure was left behind. Very thorough team."
Cons: "not friendly staff delayed and no help. cost me so much did not get anything"
Pros: "Roomy seats & clean appearance and modern cabin."
Cons: "Boarding would have been improved by utilizing both cabin doors (front & rear). The entertainment system did not work during my 13 hr flight."
Pros: "The crew was amazing. Food was top notch, and, in business class, served to order anytime. The seats were comfortable and the supplied noise cancelling headphones were great. Pillow, blanket and pajamas supplied were all nice quality. Restrooms kept spotless through a very long flight. Best business class I have experienced on any airline."
Cons: "The one glitch was the entertainment system, which froze several times and needed to be re-booted."
Cons: "Worst customer service"
Cons: "Too late."
Cons: "Tiny seat spaces"
Pros: "Almost everything"
Cons: "Dont have special food for little ones."
Cons: "I had chicken three time on the flight. To spicy for my tastes. Even scrambled eggs had a hot sauce on them."
Pros: "I like the space, equipment that work Space in comparison with other airlines but could be even better once human rights become more important than cashing in ( that is a comment meant for all airlines"
Cons: "The wifi was useless"
Pros: "Crew, especially Amrita."
Cons: "There was no separate seating area/lounge for business class at Doha , before boarding. Did not find a seat, had to stand before boarding started, all seats were taken by other passengers, no attempt was made by crew , no solution or accomodations were offered , when asked."
Pros: "Great service, alcohol selection"
Pros: "Service all crew excellent"
Cons: "Boarding tome"
Cons: "Our flight was delayed which caused us to miss our international connection. Flight attendants did not care, did not attempt to get us out faster, or put on a different flight. Asked for an announcement to be made on board or to be moved to seats closer to the front so we could get off the plane quicker, did not happen. Offboarded and sprinted across the airport for our international connection and was notified by gate attendents that the gate closed five minutes ago and that they could not let us on the plane. Meanwhile, the plane sat there for an additional 30 minutes while it fueled and waited for release from air traffic control. There were six travelers total stuck there in San Fran at that gate, all of us begging to be let on the plane to Beijing, the last one for over 24 hours. Zero compassion from staff at the the airline gate. They did not care about us and did not care about leaving their travelers stranded. Our total travel was Denver to Bangkok, 26 hours of travel including layovers in San Fran and Beijing. In San Fran (after missing the gate connection), United rerouted us through Haiwaii and the customer service agent that did this reroute did not finish the reroute to our final destination. We got to Haiwaii and were stranded again, at the United service desk for four hours having to once again provide documentation of our initial travel plans to Bangkok, having them build a new itinerary to our final destination. Overall, 20 additional travel hours have been added to our itinerary, almost double our initial travel time. We have had to call and cancel pre-arranged bookings in Thailand as we are now missing two full days off our trip. I am absolutely disappointed and heart broken as I write this still stuck in the Beijing airport waiting another six hours to connect to Bangkok. My fiancé and I were traveling to Thailand to get married and have received no compassion from anyone at this airline to try and get us there. I fly United for work quite frequently and have never experienced such horrendous service and lack of basic human compassion. I am flat out disgusted by United and will not be using them again, for personal travel or work related trips, because of this horrendous experience."
Pros: "The layover in Denver worked out perfectly - no long wait. The United entertainment availability. Friendliness of crew. On-time flight."
Cons: "The leg room. Small size of complimentary snacks. No screens for United entertainment so you had to use cell phone, but this eats battery and no power in our zone"
Cons: "2-1/2 hour delay due to poor maintenance"
Cons: "Seats in economy were cramped! Chair barely leaned back at all. Woke up with a sore neck. Cabin was freezing!"
Pros: "The flight attendant was trying to be accommodating. I and other passsengers bumped our heads when getting into seats. Can we say SMALL plane?"
Pros: "The crew"
Cons: "The seats r too small"
Cons: "I missed my flight due to a nonsense delay from Charlotte. Arrived at the gate 1 minute after scheduled take off and the plane was gone. Not even an attempt to waiting as I ran, 5 months pregnant, through the airport. I was rebooked to arrive in Las Vegas at midnight. 12 hours after the original time. I bought a flight from Southwest. I will never fly united again"
Cons: "No food no entertainment. It's a sad change from how United used to be"
Pros: "On-time departure and courteous crew. Smooth flying on this leg of our trip."
Cons: "I don't have any major complaints about this flight."
Pros: "The crew were polite and friendly."
Cons: "A cookie was the only snack on a more than 3 hour flight."
Pros: "good entertainment through the united app"
Cons: "That my flight got delayed in Denver over an hour and I missed my flight from LA to BJX because of that. I was suppose to land in BJX At 6am on Friday April 28th for a family emergency and now my next flight isn't till 1pm! This is the worst flight experience I have ever had in my life. Never in my life will I ever fly with united again. My plans got ruined, I was forced to sleep on the cold dirty floor of LAX. This cost me a lot of time and money, and I am upset about it. I will tell all my peers about this horrible experience and encourage them to never fly with united ever again. I do expect some sort of compensation over this horrible experience."
Pros: "On time from Checking In and Departure"
Pros: "Nothing was positive"
Cons: "Whole experience was terrible"
Pros: "Phone charger at every seat"
Cons: "Earphones for movie did not work"
Cons: "Very late."
Cons: "Boarding by zones causes passengers to have to stand longer while waiting to board, inconveniences them by having passengers seated in window and middle seats often arrive after the passenger in the aisle seat, and slows down the entire process because passengers settling into the front part of the plane frequently board and stow luggage while those seated in the back queue up behind them. Compared to boarding by row, the entire process is now one lengthy mess."
Cons: "My flight was ten hours late and no accommodations were provided. 40% off tickets to hotels and no way to get to them."
Pros: "I liked the power outlets that were available, as well as the USB! I have trouble sleeping on flights, but the great options for the in flight entertainment made it more than bearable. I will always choose to fly United now."
Cons: "Very bumpy ride....but I realize that can't be helped"
Pros: "Nothing is good about united."
Cons: "Had to fly into Memphis instead of Nashville in order to make my event. United didn't even help me do it, I figured it out myself . Asked for a refund and they gave me $3. Had to drive 4 hours and rent a car for $75 just to make my event on time that I had planned months ago. United is a terrible airline and I will never fly with them again."
Pros: "Amazing plane with great features! Incredible staff!"
Cons: "Bathrooms should be bigger"
Cons: "Delayed and got downgraded"
Cons: "Upon approach we were suddenly deverted to Seattle. I had a few issues. Number one you could not hear the pilot so that made it worse. The lack of communication was horrible. I have been on flights when there has been clarity given a change in plans but this was bad. We sat at the gate for an hour and a half, again no real communication, the fligh attendant t hope was joking when he said there was a half a bottle left for the whole plane...much later we were served water. Announcements were made but no clarity. We were told to collect baggage at number 2. Get a voucher for a hotel. After deplann9ng about 25 of us stood in line at the customer service desk where there were two staff working slowly. Then after an hour they announced we were in the wrong place, couldn't that have been explained earlier? Once we made our way out of the terminal to the ticket count the line was all the way down the hall. still with little info we waited. We landed at the alternate airport at 945, at 130am I had my vouchers, the food not useful until the following day, the hotels were full, no one picked up the phone for the shuttle bus to the hotels. I finally elected to sleep at the airport on a bench. We had actually all been reassigned a flight on our same plane. So I am not sure why we had to wait in line all that time. Our bags were not removed from the plane an irritated baggage claim attendant told me. It was a mess. The flight the next morning was fine, short, without problems for me. united needs to work on its communications. It would have been helpful to have someone out side running the line giving out info. And at customer service they should have been paying attention to their line. Would have been helpful."
Pros: "nice flight attendancts"
Pros: "Good crew, smooth flying, on-time"
Pros: "There was a lot of space and a quick departure."
Cons: "When we got to LA event though we were early we had to wait. I know its not the airlines fault but it sucked."
Pros: "The crew was very kind to everyone and it was a very pleasant flight!"
Pros: "Crew was great"
Cons: "Aircraft interior is dated."

Cons: "No problems"
Cons: "The plane temperature was ice cold and I was miserable the entire flight home"

Cons: "Having to go back to Denver because of a storm-in Omaha."
Cons: "I think United is improving constently"
Cons: "Seats are not comfortable and no leg room"
Cons: "Crew was not particularly friendly. One man was brusque when I asked for water to fill my small bottle. Rare since most crew members I've experienced have been very pleasant. Snacks were pretty paltry. Ned to serve some biscotti."
Pros: "Everything went smoothly, and that's really all that matters. The crew was great."
Cons: "Don't know why we have to pay for entertainment. It used to be free."
Pros: "I liked the flight attendants that they were courteous and helpful"
Cons: "I am a fearful flyer and that is putting it mildly. I didn't like that the pilot didn't introduce himself and talk to us about the flight."
Pros: "I liked nothing"
Cons: "I didn't like everything. All my United flight were delayed, the international was cancelled after waiting for 7 hours of delays."
Pros: "Crew nice and friendly."
Cons: "Free in-flight entertainment should be offered on all flights of 2+ hours through the United app. Had a family with young kids next to me who would have benefited from it (I saw the father trying to connect to it through the app), and overall it would make the flight a much more pleasant experience. After boarding a full hour later than what was originally said, it would have been nice to kick back with a movie for the flight."
Pros: "I know it's some sort of miracle. But there was only 40 people on an airbus. We all had about 3 seats each and we made full beds for ourselves."
Cons: "Boarded and left late for many to miss connections. No real help to get to new connection both on plane and off."
Cons: "Delays! Numerous delays! No assistance to help with changing missed connections or getting a hotel while stuck in Chicago."
Cons: "Great employees!"
Pros: "Good flight attendants"
Cons: "Small seats"
Pros: "Great Entertainment choices"
Cons: "One flight attendant seemed to be annoyed by most people. I am allergic to onions, so I was not able to eat any food provided."
Cons: "Delayed 3 times. United is known for delays, everyone jokes about United delays!"
Pros: "crew personable"
Cons: "Wifi didn't work"
Pros: "This aircraft is like magic. I love the magic windows that tint to your comfort and through which you can still see the Aleutian Islands at "night" when everyone is still trying to sleep. I love the higher pressure and the higher humidity in the cabin that makes you feel merely "tired" after a trans-pacific flight, as opposed to "exhausted," as you would feel after a 747, 777, 330, or 380. Please don't tell United this, but I would pay a large premium to fly the 787, and I'll take it through DEN to get from NRT to SMF, even though it would be much faster through SFO or SEA."
Cons: "Well, it was still United. Saw one crewmember picking his nose (he would have gotten dismissed upon landing at SQ or CX). The downside of the crew override on the 787's windows is that they sometimes leave the cabin "dark" even while they're serving the pre-arrival meal under full cabin lighting. I often have to ask them to release the controls."
