Cons: "A delay of 28hrs is never positive. I haven’t been able to get my United points either since I was rerouted to SFO. When claiming them the system says that I never boarded the flight to EWR and completely ignore the YYZ - SFO flight. Mediocre overall."

Cons: "At the time at the gate did not allowed me even take my caryon bag with me, the staff was so rude an in an uncivilized manner start fighting with me ,I am a sinor person got very disrespected by your staff, I would like to bring a lawsuit against UA for what you did to me ,I wish an invitator from your office contantact me to explain everything,"

Pros: "Premium seating was worth it! I actually had room to sleep and the service was great."
Cons: "Toronto's airport did not send our bags onto or flight, which I had to wait 8 hours for them to send it to my hotel. Plus, the boarding process was crazy. So many people waiting in front of the lines for them to be called. Luckily, an attendant was calling out for premium. He guided us"

Cons: "Working on flight schedule to be more precise! Delayed!"

Cons: "Crowded planes."

Cons: "At YYZ @ the wheel chair entrance, I visibly required wheel chair assistance. I approached the United INFO COUNTER and requested wheel chair assistance. She advised me to get into a long Q and after check in they will get me a wheel. chair. TSA is no greater help for your air line."

Pros: "On time. comfortable aircraft."
Cons: "Retrieving cabin luggage at other end: THey make you line-up in the jetway waiting for the handlers to bring it up the stairs. Took a while to get that sorted."

Cons: "Not having videos on plane in seat sucked!"

Pros: "Nothing because we didn’t leave Guam, was not allowed to go Japan due to having a green card and Philippines Passport."
Cons: "Service Overall of how we were treated by a bad customer services is really terrible and bad."

Pros: "I didn't like nothing"
Cons: "United needs to training your employees"

Pros: "Crews were great"
Cons: "Seat cushions were old and hard to sit on in excess of an hour. The don't look worn out, but certainly no one is asking. Not very comfortable for a four hour flight."

Pros: "Flight was on time and short in duration"
Cons: "Seats rows were narrow with just enough leg room. Very confining and uncomfortable. Our row did not recline as we were in front of the exit row. Luckily, the person in front of me did not recline their seat back."

Pros: "Crew was curteous and capable"
Cons: "The screens on the back of seats that used to play movies now play advertisements and ask you to pay for in-flight entertainment. The off button did not turn the screen off, resulting in a constant eyesore for the entire trip"

Pros: "Good flight"
Cons: "2 Delays"

Pros: "Crew was excellent and hospitable."
Cons: "Need rest room in middle area of plane. Movies need to change weekly. Same movies a week later."

Pros: "The service staff was very friendly when they told me they were out of every food item I wanted."
Cons: "Lack of variety in snacks, foods and purchases on the plane."

Pros: "Flight was cold and they did not have blankets"

Cons: "The movies kept doing out. They told us to log in and get compensated in a few days"

Cons: "Flight was delayed Before we boarded but then once we boarded we Sat for another hour."

Cons: "I don't fully understand why, but I was unable to get my boarding pass for my flight to Chicago from Toronto until I arrived in the Toronto airport. Toronto airport sequesters off international arrivals, so in an ideal world, I would have been able to go through security directly to into the U.S. terminal, bypassing Canada customs. However, the United desk that I needed to get my boarding pass from located just before security was unmanned. The very kind Air Canada attendant called for a representative multiple times, but after 45 minutes of waiting no one ever arrived to print my boarding pass for me. The Air Canada employee then gave up on any United staff showing up and suggested I try going through Canadian customs and checking in at the same departure desk travelers first entering the airport would go through and make sure to let them know how long I was waiting. The United employee I spoke with told me that I was impatient and should have continued waiting because now she didn't know what would happen with my checked bag and that I may well need to wait 2 hours more for that to get sorted out. I was rather surprised by her overly negative response and apparent threat. If I was irate or yelling that might have been warranted, but frankly, I was so tired from the international travel I didn't have the energy to fight with her. Regardless, I wish I had been more impatient, it was far easier to go through customs twice than I expected. I would have preferred to spend more time in the lounge inside the terminal than to stand by the United desk waiting for someone to arrive to print my boarding pass. At any rate, Canadian+US customs have it together; when I went through U.S. customs to get into the terminal they had the photo of my checked bag right there."

Pros: "Nothing"
Cons: "Everything"

Pros: "My complaint with United is twofold: extremely poor customer service and airport experience. First, the plane was delayed Then cancelled took customer service 50 minuets to rebooked on a new flight to sfo instead Sjc which is far away from my house & I paid for CAB!!"

Pros: "This was an average flight on a small, cramped, RJ/CRJ. There was nothing special about this flight and this review is only to stop the over abundance of emails Kayak sends you begging for a review...."
Cons: "Please read what I wrote above."

Pros: "The crew on this flight were really nice and helpful."

Cons: "They delayed my flight, so now I get back home really late. Thanks, United."

Pros: "Crew was friendly, boarding was easy."
Cons: "I wasn't informed when I booked that the flight was operated by Air Canda's budget variant, rouge, and not Air Canda as was listed on Kayak. I had no option to select seats, and when we boarded I was seated on the last row by the galley with no reclining seats and the florescent lights were on nearly the whole time on a 10 hour overnight flight. There are no seat back TVs and the free streaming service went down repeatedly just like the AC outlet at our seats (there are only two of these for three people). I booked this trip nearly a year in advance, and I am extremely disappointed that I wasn't informed that I was flying a budget airline on a 10 hour flight."

Pros: "I like that we landed."
Cons: "This box seems too small to fit it all in. It's United - underwhelmed as usual."

Pros: "Boarding was quick and efficient."
Cons: "It seemed that there was a lack of preparedness before taking off from each stop."

Pros: "Was delayed two over two hours in HNL. When UA decided to transfer all passengers to another plane, it was such a beautiful flight and the Pilot of the plane."
Cons: "I didn't like the idea that we went given a free meal because the plane broke down."

Pros: "Window seat"
Cons: "Same experience on ANOTHER 8 hour flight I have NEVER flown on an international flight and NOT received a complimentary meal or two...When I'm flying for 8 hours. On top of that the seats were very small and uncomfortable. I shouldn't feel a person grabbing a magazine or pulling down a tray when I'm sitting in the seat in front of them. I couldn't consistently watch a show or movie for 3 minutes thanks to the wifi and or app on MY Samsung tablet....it's SO sad that you guys couldn't have them already installed like other airlines. This airline is already in hot water, I expected MUCH better customer service. I will do my best NOT to use them again and tell others to do the same."

Pros: "Crew did the best they could"
Cons: "4 hour weather delay; missed all connecting flights; spent night in O'Hare; no food at night; no vegan food; got home 12 hours later than planned with little no sleep."

Cons: "Delayed departure"

Cons: "Seats are so narrow and uncomfortable. And we never pushed pack on time for all my flights"

Cons: "Incredible long walk passengers should be told when you have such a distance to walk. Passport sign in is not very user friendly should be a better scanner and easier questions they are confusing"

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: "Plane was on time"
Cons: "No food"

Cons: "They kept delaying this flight but not telling us. First it was delayed to 6:50; at 6:51 I asked whether it was further delayed and was told no, we were about to board. Five minutes later the screen said 7:15 (and later, 7:35); at no point was there any announcement about these further delays. They then stowed carry-on luggage below, so passengers lost access to any entertainment in their carry-on. There was no entertainment on board."

Pros: "Fantastic minus the fact this flight was canceled without any notification."
Cons: "I wasn't notified that my flight was cancelled until I tried to check in online a few hours before. Then I was booked on a terrible next day combination. I had to book with another carrier for $400. I missed out on time and money."

Cons: "3+ hour delay"

Pros: "Staff were helpful, the flight took off on time and the trip was smooth."
Cons: "No complaints on any front."

Pros: "I was pleasantly surprised when they announced those with large carry ons could get tagged and pick up at final destination."
Cons: "The distance between arriving gates and departure."
