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

Pros: "Average flight. Crew was polite."

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: "Entertainment, food, comfort"
Cons: "Slow boarding/alighting, entertainment system was too sluggish"

Pros: "This is what airlines used to be like. The food and quantity were excellent. Too bad these services aren’t offered on domestic flights. We had a snack or meal every couple hours with plenty of drinks. The legroom was ample and comfortable."
Cons: "N/a"

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: "Nothing"
Cons: "The fact they wasted two days of my trip with my son travelling from the U.S. to China because they didn't know about transit visa regulations. And so far they offered a 75 dollar voucher for participating merchants. Unacceptable"

Pros: "Crew was excellent everything served was of great quality, all the amenities were solid and flight was comfortable and on time."
Cons: "The only complaint was the extreme use of air conditioning that made it a necessity to use many blankets to keep warm from freezing."

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

Cons: "*Again, my first choice of main off the menu, in Delta One, had run out. *Not a fan of the Delta One 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."

Pros: "Decent choice of entertainment options."
Cons: "Crew was racist, grumpy and dismissive. Boarding on and off the plane was chaotic to say the least."

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."

Cons: "Not enough sitting space felt very cramped"

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."

Pros: "Nothing"
Cons: "Everything"

Cons: "The boarding time"

Cons: "Cabin temperature was set too high that caused dryness"

Cons: "Unable to choose seat"

Cons: "We arrived to one terminal and no one says that the next flight was in tom bradley terminal. After asking on the way, I realized that had to walk more than 35 minutes. No transfer service, no info, nothing. Finally after reach tom bradley terminal, the ANA staff said that they was very delayed and wanted to change my flight."

Pros: "Boarding went very well. Seats were good."
Cons: "We missed our next flight due to being called back to the gate for some cargo issues. Because we missed that flight we had to wait 3 hours for the next one which caused us to miss our bus reservation and ended up costing us about five extra hours in time. Staff was not very attentive."

Cons: "Upon checking in a boarding time was given of 0530. A line formed to get in a row 1/2. I would think business class would have a separate boarding rather than line 1. Once in line there was over an hour delay in boarding with no I repeat no information coming from the boarding agents, people were not happy as I heard many complaints. I was lucky and got a electronic notification but no reason. What a way to start a vacation!"

Pros: "nothing! entertainment should vd a one alos, not s friendly star system"
Cons: "over an hour wait. gate agents change in the middle of the wait time... no info was given s to what the mechanical problem. did di a very good job in communicating time! just totally screwed up."

Pros: "On time and nice services"

Pros: "frequency of drink/food service. Appreciated the ice cream."
Cons: "Food was not good. chicken or pasta were the choices, we sampled both. Neither was good - some of the worst airplane food Ive had. On our return flight from Munich to Houston we had same choices but it was a different type of chicken - curry chicken - and that was excellent. I would recommend you serve the same thing on your Houston - Munich flights! Seat comfort (bottoms) not so good."

Cons: "Bad actitude of personal and crew"

Cons: "Need power supply for passenger seats in Economy Plus."

Cons: "movies: screen froze every few minutes throughout the flight in biz class: nor more brandy/cognac; menu rather limited"

Pros: "Rude gate staff. They were being very condescending in their tone while saying perhaps appropriate information. This occurred starting when one woman got in line. The sign kept changing...her accharine like tone telling her that boarding would begin at 1130 was unnecessary. Communicating with foreign passengers whose flight had been rebooked to this flight was very poor. Instead of asking them for the name of their baby, the gate employee kept asking them for the lap child name! This occurred over and over until finally they asked for the bany's name. The lady who is from Chicago started practically wagging her finger and just saying NO! to bags that might be too large. How she did this was overly rude even when the bag fit in the metal sizer!"
Cons: "Sorry....above is what I did not like. I like that my bag was shifted away, tagged and put on board...made it to Rome! Flight staff very professional!"

Pros: "On time departures and landings"
Cons: "Food was horrible! Vegetables so overcooked they were almost liquid. Overly salted. Best thing was Chobani yogurt... pre done by Chobani."

Cons: "Food choice was awful. Ended up eating just a salad"

Pros: "Seating was larger than normal for economy. Crew was pleasant and made lots of offers for food and drink. Flight was on time and the luggage arrived unharmed"
Cons: "All good"

Pros: "Service and crew were much friendlier coming back from Rio."
Cons: "Food was terrible, seat as uncomfortable."

Pros: "The flight took off and landed on time."
Cons: "When I went to the gate in Houston to get my boarding pass for my second leg, the lady at the gate counter yelled at me because I didn't know my seat assignment even though I had already explained that I didn't know because I didn't have a boarding pass. On my original booking, I had chosen my seat to be a window, but when they rebooked me they put me in a middle seat even though there was a completely empty row in front of me. Then, to top everything off, they forced me me check my rollerboard carry-on because they said there was no more room on the plane, but when I got on I could see multiple spaces were still available. Another passenger and I were left to wait nearly 5 minutes on the jetway while the gate counter rep went to print our checked luggage tags. I asked the stewardess why I had to check mine even though there was plenty of space, and she said "it's hard to tell sometimes how much room we're going to have left." She also didn't offer any apology. All in all it was a terrible experience. I had to wait unnecessarily at various points of the travel process, had to endure a layover that was more than double what I had planned for, was forced to check my carry-on at the gate, and worst of all I missed a really important meeting. United obviously does not care at all about economy customers. Don't trust this airline! Book on Southwest or JetBlue - they actually care about customer retention!"

Cons: "Both flights were delayed, and was charged a $200 oversized baggage fee for a bag that actually isn't oversized according to the measurements on the United website"

Pros: "Crew was efficient and curtious. Dinner (veg option) was good."
Cons: "Enterrtanment system not working well. Breakfast was minimal, bread very dry."

Pros: "priority boarding; screen size of monitor"
Cons: "seat width (too narrow)"

Pros: "Good crew. The crew is very nice and accommodating. On my previous flight with United the crew was Kurt and not so good. Sorry very happy to see how nice and accommodating this crew lunch."

Pros: "Nothing to like because the flight was canceled and flights the next day only had standby"
Cons: "Everything! We will try our best to never fly United again. They offered no compensation for our canceled flight and we incurred $400 in additional charges trying to get home a day late!"

Pros: "Great flight friendly person sitting beside me, would like seat towards front but my husband likes sitting in back , we had seats in row 27 & window seat for him he likes looking out. It was very enjoyable. Thank you"

Cons: "Flight attendant was really not very nice at all. I felt like I was in trouble for even taking the flight. 'Move your feet. Bags have to be moved under seat. I need to see your seat belts.' She was curt, unfriendly & really made me upset with her bad attitude. Maybe she was having a bad day but I paid good hard earned money for my trip. I at least deserved courteousy & mutual respect."

Pros: "I am happy the pilot caught the faulty engine before we were in the air. That probably wouldn't have ended well. I like the snack choices."
Cons: "We were late boarding. Once on the plane flight was delayed longer due to a maintenance issue. Once on the run way, pilot said one of the engines would not start and we would have to turn around."

Pros: "Suitcase arrived at the carrousel on time , much better than Houston."

Cons: "HUGE DELAY. MISSED CONNECTION. CONSTANT UNCERTAINTY"

Pros: "Everything went by smoothly, no problems"

Pros: "They let people get on with oversize bags when sequence 4&5 get on there's no room left"

Pros: "Zero leg room! That actually was surprising as most other airlines have a lot more legroom. In flight entertainment was also lacking. Doesn't make sense to pay $7.99 for a 2.5hr flight. A lot of other airlines offer some sort of complimentary in flight entertainment. Also the luggage didn't start coming out for at least 30 mins of waiting at baggage claim. Not the worst experience I've had flying but far from being a good experience. It probably isn't worth flying united unless it's 1st class. But even they had to wait 30+mins for luggage!"

Pros: "About as comfortable as a trans-pacific flight gets in economy class. Plenty of leg room, great entertainment choices, surprisingly good food - and plenty of it, by the time breakfast came around I was actually too full to eat it!"

Pros: "On time"

Pros: "I was upgraded to economy plus aisle seat"
Cons: "Flight delayed about 1hr"

Pros: "Getting off"

Pros: "This crew is probably the best I've experienced traveling this route in years. They were professional, attentive, gracious and friendly. I was just thinking what a joy to watch them interacting with different people from the nice ones to the difficult ones. You guys rock"
Cons: "Explanation for the delay in boarding"

Pros: "The length of the flight was acceptable."
Cons: "My seat was moved futher back in the plan 34D, seats were smaller, knee space tight, the air back here was unpleasant (b.o.). Very noisy. The stewardess did not know how to operate the entertainment screen, finally she said I needed headphones, once I was hooked up volume up High I still couldn't hear the movie, to much outside noise, I thought the guy behind me was shaving. The Asian snack was dreadful no beverage available for awhile."

Pros: "Lining up in groups"
Cons: "Nothing"

Pros: "Gate personnel were great."

Pros: "Crew, Entertainment options, spacious seating"
Cons: "Nothing"

Pros: "None of the issues related to a service dog came up on this flight."

Pros: "Boarding process"
Cons: "No food... Sporadic drinks.. Very cheap service"

Pros: "This was my first time flying United and I was very happy with everything. Hopefully my opinion will be the same on my return flt."
Cons: "It would have been nice had i been able to recline the seat a bit more. And some sort of remote for the games...To play the games u have to lean forward and sit with ur arms raised to touch the screen and that get very uncomfortable...It might not b important to everybody ...but since u asked..."

Cons: "Nothing Missed my flight due to united being so unorganized. Didn't realize even on international flight you have to pay for food !!! And much moe I didn't like !"

Pros: "Great seat i had to pay extra but it was worth it"

Pros: "The service was quick by flight attendants, 5 minutes in the air we were served immediately. Then people were sleeping and relaxing. Thank you"

Pros: "If just two rows of seats could be removed it would make things so much better. I'm only 5' tall and still barely have enough room. My boyfriend is 6' tall and can't even move once he's in. Of course it's hard financially to pay $300 extra per ticket to visit family so we suffer through."

Pros: "Clean, and comfortable"
Cons: "No tv to watch"

Cons: "Hate the airport"

Pros: "Very helpful and welcoming personnel every step of the way. Thank you all."
