Pros: "The entertainment can stream a large library of movies to your device"

Pros: "Staff did a great job communicating about turbulent situations & delaying services"

Pros: "It was a regular nothing different flight then what was expected."
Cons: "Need to develop the entertainment system to become at least minimumuly adequate. I have learned to treat these flights as buses in the air."

Pros: "I have always loved flying Lufthansa however we didn't fly Lufthansa, we were on United for both legs of our flight. Like all American opperated airlines they skimp on comfort in order to pack more people on their flight. I hope we are on Lufthansa on our way home at least."
Cons: "We were on United, see above."

Pros: "Nothing"
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: "The crew were polite and helped to assist the passengers who has the same seats."
Cons: "The fact that I had to download an app for onboard entertainment prior o my flight is farcical."

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: "I"
Cons: "I think United is improving constently"

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."

Pros: "A everything was fine other than..."

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: "I like how I made it to my destination even after a huge blizzard in Denver."
Cons: "We were really delayed while on the air plane and the seats were not as comfortable as before. I understand that the delay is not the crews fault but actually DIA, but it was my least favorite part of the trip because it made me late to an appointment in Tucson."

Cons: "Their plane broke down, no assigned gates ,"

Pros: "Clean cabins and good service. Also, an informative pilot who made sure we knew why we were delaying the flight."
Cons: "We only received drinks on the flight, but it was short, so it wasn't a big deal."

Pros: "Regardless of product, the 787 is by far the most comfortable aircraft in the sky. Obviously you can't compare UA Economy to EY's "Residence" on the 380, but once you're comparing similar products across different aircraft, the 787 blows all the others out of the water. This is because of the higher cabin pressure, higher cabin humidity, and relatively enormous windows at eye level. Even UA can't ruin the 787 experience with their snippy staff (I almost found myself apologizing for asking for the little bag of snack mix that I missed out on because I was snoozing when they first came around) and ear-splitting announcements. The flight was delayed due to a mechanical, and the staff at NRT was very helpful in getting us to where we needed to be."
Cons: "The plane had a mechanical issue that they had to sort out after we pushed back. This was not so bad, but they changed their minds about whether we would take the original plane or switch to a second 787 that had flown in on NRT-DEN so many times I lost count. This is why I gave the "boarding" process poor marks--please just figure out whether we need to get off (we didn't need to, but did anyway) and whether we are going to switch to another aircraft before letting everyone off. The staff at NRT failed to consider moving the DEN-HKG passengers to a ET NRT-HKG flight (which surely had available seats) that was parked next door. Instead, we were all put on a HND-HKG flight leaving about five hours later than the ET flight."

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."
