Pros: "Food was so good. Crew was also very nice."
Pros: "Check in person was very helpful in rerouting our flight."
Cons: "Our flight was delayed 3-1/2 hours. The gate crew booked us in another flight but did not issue a ticket, so after transferring to another terminal, we were sent back to the Delta terminal to be issued a ticket to a third airline since we already missed the second flight. Then, they lost our luggage"
Pros: "Good crew"
Cons: "The WiFi didn’t work well"
Pros: "New plane, charging stations"
Cons: "Seats did NOT recline, which seems to be a pretty poor planning for a red eye flight."
Cons: "I feel like all the problems the aircraft had it should've been repaired before trying to use it, upon boarding they told us the left engine had to be started from an external source, as a new flyer that was terrifying to hear"
Cons: "The boarding process at LAX was awful. I’m sure the horrible shuttle wait and transfer from terminal to terminal is the airport’s fault, but the airline did not do anywhere near enough to inform passengers of what was in store. It was confusing and annoying."
Cons: "They did great. The weather was poor, so it felt more like a roller coaster ride home. Made it safe and sound. Would’ve been nice to get an update is speaker about change in weather and the rough ride in store when the whole ride was so turbulent."
Cons: "I checked two bags and paid for them. The flight was full. I dutifully got in line for zone two. Next thing you know, at least 25 people got to board early and have free bag check. Really? I should get $35 dollar refund."
Cons: "Was not allowed to check in even tho flight was delayed. Horrible!"
Cons: "No dairy free options!"
Pros: "From check in from Delta App till receiving luggage, very smooth and painless process. Thank you!!"
Cons: "Separated from my wife even with pre-assigned seats. And One of the stewardess would not take my banana peel and has asked me to dump it into lavatory trash myself. She did not want to handle banana peel without a glove."

Pros: "Exceptionally helpful & attentive flight attendant, comfortable, on time"
Pros: "Cannot. Figure out how to use the wifi."
Pros: "I was still full from flying a Delta international flight from CDG to ALT, so I opted out of all food. They just offered snacks and beverages."

Cons: "1. Wifi didn't work"

Pros: "Movies"
Cons: "Lack of legroom in economy"
Pros: "I was a little concerned flying West Jet due to poor experiences in the past with Delta, but the flights were on time, staff friendly and accommodating and the plane very comfortable."
Cons: "Nothing negative to say!"
Cons: "Left about 2.5 hours late because of a broken seat of all things. Apparently Delta doesn't bother to have maintenance staff on site at the airport."

Cons: "It was really cramped and the bathrooms smelled very strongly."
Pros: "Nice plane, smooth flight, flight was on time in spite of the disaster in Houston."
Cons: "There was food listed in the book but it was never offered. On a 4 hour flight, this is too long! Wifi was broken...I bought a $20 pair of earbuds in the airport specifically to watch movies and was never able to use them."
Cons: "The plane was about 10 minutes late departing (not too bad), but the Entertainment System was down for the flight, meaning that in addition to entertainment, the USB and outlet charging was not working and you couldn't see current flight status."
Cons: "The crew didn't even have the decency to wait for passengers to deplane. They were long gone by the time we got off. I found this pretty terrible service. Oh yeah and they announced the wrong arrival gate too. I'll never fly Delta again. There are better airlines that treat customers with more respect."

Cons: "Snacks if possible"
Cons: "Several hours was added to my travel day when my Calgary to Seattle flight was cancelled and I was rerouted from Calgary to Vancouver to Seattle. It seems to me that if an airline initiated change that significant occurs, I should have an option given me to change my itinerary."
Pros: "I liked that from China to Seattle on the flight itself they took very good care of us making sure we were all comfortable, hydrated and well fed."
Cons: "The Shanghai airport did not open luggage drop off until 3hours before my flight when I was told it would open 5 hours prior, as well as tried to get me to leave to rent a hotel for the night as my layover was a few hours, then delayed Seattle boarding for over 45 minutes, once we were on the plane we were then told we were number 25 to leave therefore leaving us another hour and a half of a delay."
Pros: "Great crew."
Cons: "Very cramped seating on this plane."
Pros: "Left on time, smooth flight"
Cons: "in Amsterdam any DELTA crew helm us, only KLM"
Pros: "Everything was great"
Pros: "Crew was great."
Cons: "Entertainment center."
Pros: "On time flight"
Cons: "Gate agent at SF was rude and unprofessional. While waiting, gate agent at gate 65, flight 647 started the following, “group 1 boarding, group 2 boarding...everybody, let’s go let’s go”. She went on to call out one, Hispanic customer with limited English, “come here, you can board now”, rude rude."
Pros: "Very kind crew"
Cons: "Flight was delayed by 2 hours and all they offered in the flight was direct tv - inflight app entertainment did not work. Also had to walk off the plane after boarding to gate check my bag. So disappointed."
Pros: "Nothing."
Cons: "They delayed our flight 4 times, over 4 hours, told us the flight moved to a gate that didn’t exist, gave us erroneous information about alternate flights, assigned 3 different planes that needed maintenance, and then we waited over 2 hours to talk with a supervisor. I finally had them rebook me on Alaska Airlines (the best)."
Pros: "Crew"
Cons: "Comfort of seats. Too close together."
Pros: "None, Zero..."
Cons: "I did not like how we were treated by the United Airline Crew front desk when we were getting our boarding pass, they immediately say that due to myself having a Philippine Passport and A US Green Card holder they needed to check with Japan Immigration and in the end of waiting they said that we can’t board the plane because of my citizenship status and I needed to get a Japan VISA, I felt discriminated for something I do not know about when I purchased the tickets via online it doesn’t even show if there were any requirements needed in order for me to travel to Japan. My overall Review is a big ZERO and Unsatisfactory of how they treat their customers."
Pros: "Snack menu, the plane was moderately clean compared to the last. Good communication about late flight."
Cons: "Staff was mostly rude, tired. The plane was 30 minutes late due to weather. Internet would not work, the captain kept trying to reboot it, no entertainment. An older plane in moderate disrepair. Economy seats were much more uncomfortable than American Airlines."
Cons: "In Osaka I was not able to get a boarding pass for this last leg. In SF United and Air China were both not able to give me a boarding pass because I was not listed in their system. I have no idea why. Very frustrating."
Pros: "Nothing."
Cons: "Everything. I will never fly with United again. I will pay more money for another airline which respects people and their money."
Pros: "Great customer service"
Cons: "My dear was extremely uncomfortable"
Pros: "Staff was very good at their job/duties."
Cons: "Seats were uncomfortable and cramped."
Pros: "Boarding quickly"
Cons: "Delayed"
Pros: "Everything was great except for the food."
Cons: "The hamburger bun was hard as a rock."
Pros: "Very smooth fligh and very friendly and helpful staff"
Cons: "The seats were extremely crammed and there were no movies or shows without purchase"
Pros: "It was a short flight"
Cons: "I didn’t like not having to choose our seat assignments after we booked our flight. I have used Kayak on many occasions and I was able to choose my seat after booking. I was not able to do that after I booked my flight."
Cons: "Seats are very uncomfortable the delay was unexplained and no information was givenuntil we boarded the plane"
Pros: "Quiet and calm smooth flight"
Cons: "It was cold in cabin at first."
Cons: "My seat had garbage on the seat, on the floor and in the front pocket"
Cons: "I was not able to sit with my husband and the man next to me drank a a bunch of red wine and the attendant brought him whiskey after that until he passed out with his baby over my lap."
Pros: "I was supposed to be the volunteer for overbooking problem, but the ground attendent helped me by arranging a seat for me. If she didn't do that, I would miss my next international flight. I'd like to say thanks here!"
Pros: "Good leg room"
Cons: "Had ro pay for entertainment"
Cons: "This flight was also late, and this was after having to spend the night in the airport"
Pros: "Staff was friendly and helpful"
Cons: "I'm signed up to get notified of changes to my flight. The gate got changed and I wasn't sent an email or text update. I'm a bit confused as to what constitutes as a"flight change update" , if a gate change doesn't qualify."
Pros: "Crew were friendly and helpful"
Cons: "Seats are very tight. Entertainment depends on bringing your own ipad or laptop and using the United system. Movies tended to be oldies. Food is 10 pretzels. Count them."
Pros: "The aircraft"
Cons: "Crew delay"
Pros: "Overall the flight process was fine."
Cons: "Kayak is not transparent enough about highlighting which flights are low cost flights during purchasing. I thought I was purchasing a regular fare where I could bring a normal carry-on onto the flight, but this was a low cost flight and I had to check my bag. This information was not disclosed until after payment, and I believe this is dishonest on the part of Kayak. Kayak needs to be much more upfront about the details of the flights so that we passengers can select flights according to their needs. I felt deceived by the fare and would have purchased a different flight if I would have known ahead of time."
Cons: "No wifi... with the amount you pay for the flight, seems insane you have to pay for wifi too"
Cons: "Plane change resulted in middle seat in far back instead of aisle originally."
Pros: "Upgraded me to a bulkhead seat to accommodate my 6ft 4 inch frame!"
Cons: "All good"
Pros: "Cheap fare"
Cons: "Nothing"
Pros: "The morning cookie was good."
Cons: "It was dirty."
Pros: "No charging docks on plane as military duffle bag open with clothing hanging out on arrival ~ not sure if anything stolen but the threat is very real and it's unacceptable for military bags to be delivered in that manner"
Pros: "Ticket price"
Cons: "Long layover"
Pros: "I was moved to business class after an ordeal but the extra room was nice."
Cons: "I came down in a wheel chair and noticed my ticket had me in an exit row. When I asked to be moved, the women behind the counter had an attitude. Many of the customer waiting to board noticed. Next she started boarding the plain and I had 3 people ask if I needed to be pushed down and they would help. She barked at us that someone was coming. Once inside I asked for help getting my plug into the outlet because I wasn't able to make it fit. The crew member told me to keep trying. Because I never could get it in, my computer and phone wouldn't work. So I figured I would purchase one of the entertaining units but none was offered. It made for a very long flight. When leaving the plane, the other crew members were very helpful and even the wheel chair attending me was a delight. I was on flight 1977 from Houston to Seattle on November 7th. I usually fly twice a month for business. After my ordeal, I will use other airlines."
Cons: "Showed up at airport w 2 15 yr olds traveling alone. We're told we needed to pay $150 each way. We were NOT told when tix were purchased. Accused of lying about the girls ages when we booked. Tix were booked and paid by two different parents and times. Agent relented and waived fee. At the gate we were again challenged and had to go thru it all again. No more United for us!"
Pros: "Prebording was helpful being disabled and having a service dog, crew was very helpful, and it was much more comfortable having the extra legroom as requested in advance and having it honored."
Cons: "I did not enjoy having to pay for even the most basic entertainment."
Cons: "Should load the plane from the back rather from the front. People in the back can sort their stuff while still be able to load people into the front."
Cons: "This flight was delayed for 1.5 hours which was not nice and it was a six hour flight and only could receive pretzels without paying for food."
Pros: "Crew was gracious, helpful, and courteous during a terrible and disruptive ordeal for passengers"
Cons: "Being stuck for nearly an hour sweating on a plane with no AC while mechanics were trouble shooting, only to find out that we had to exit the plane, and that it could not fly. Passengers had no idea what to do - whether another plane would be sent for us, whether United would reimburse our ticket if we arranged another flight on our own, etc. We were left to fend for ourselves. I had a wedding to get to with many pre-wedding events, starting this evening. So, I looked for another flight, found one, booked it, and went to United customer service to request reimbursement for my ticket. I was told that United had just learned that another plane was coming for us and would arrive in 30 minutes, at 8:10. (My original flight had been at 6:35). The other flight I had booked was at 10:30 pm. So, United customer service changed canceled my new booking and put me back to my original flight, now arriving at 8:10 and boarding at 8:50. The plane did arrive, but we did not board until 10:50 pm. My flight left at 11:02 pm. Bottom line is that my flight was delayed 4.5 hours. I missed an important event that I was supposed to host. I missed my only opportunity to see a dear friend (and guest of honor) - this is someone I have not seen in person for ten years and was the guest of honor at tonight's celebration that I was supposed to host and missed. Furthermire, I could not carry on a bag that I have carried on for years, and that would have easiky fit. Having to check my bag left me without my phone charger. Of course, the fact that we were 4.5 hours delayed meant that I ran out of power shortly into our long flight from Washington. to Seattle. And the food was awful - stale nuts, . ;, b:;"
Pros: "Polite staff"
Cons: "The boarding process was chaotic. Overhead bins were full, but flight attendants were not available to help people struggling to find a place for their baggage. They should've offered to gate check baggage"
Pros: "Flight crew was attentive and kind."
Cons: "We had to sit on the Tarmac for 20 minutes before taking off due to low cloud cover over Seattle."
Cons: "The delay ruined our evening and made the expense of a hotel for the night and babysitting moot because we might as well have flown the next morning. So much for seeing friends in Seattle on Thursday night. A 2 hour delay means we just get to sleep in an airport hotel for no reason."
Cons: "Boarded, then deboarded due to missing rivets, flight delayed nearly 4hrs, luggage claim took close to an hour"
Pros: "Aircraft, flight (except for late arrival at gate) and service"
Cons: "Pilot announced we would arrive early in Seattle. When we go to Seattle we waited 30 minutes for a gate and actually arrived late. When we got to baggage claim we had no claim area posted for our flight; another 15 minutes waiting to find out where our luggage would be"
Pros: "Everything listed above is accurate of the 1st flight. I had just as much leg room on the 2nd flight as the first with it being even more crowded. Doing well!"
Cons: "Nothing comes to mind that I would be willing to say anything about."
Pros: "same as above"
Cons: "Delays caused missed connections in not directions and terrible rerouting plus lost luggage"
Cons: "We boarded in the plane late. When I got to Manila, my luggage was not there! The agent told me, and the others that didn't have their luggages, that the crew in Guam thought that the luggages' final destination was Guam. I didn't get my luggage until the next day!"
