Pros: "Quick"
Pros: "Comfortable Flight"
Cons: "Inflight WI-FI doesn’t work, it kept on dropping in the middle of the movie or it went back to the beginning. Couldn’t see a movie."
Pros: "Nothing! I will make sure to never use United for any flight from now on."
Cons: "Everything! The customer service was terrible and cold. Non refundable tickets should state in huge red writing that they are non refundable!!!"
Cons: "You better get rid of basic economy."
Pros: "No delay, friendly crew"
Pros: "Boarding was fine, no delays. Crew was nice, no complaints there! I had an empty seat next to me, so could stretch out. Luckily I brought a blanket with me, since I know from previous experience it's always too cold on planes."
Cons: "The entertainment didn't work on my iPad or my iPhone. I kept getting an error. Also, the WIFI is way too expensive."
Cons: "United has new seats that have absolutely no leg room and are very uncomfortable. I will make sure never to fly United again. This was 3 hours of agony."
Pros: "Associates were nice and knowledgeable. The airplanes were comfortable. Love the onetime performance of scheduling."
Cons: "Unite Airline performance wasn't the good. Also, there was nobody in Chicago to help us with the transferring process."
Pros: "I had the exit window and that made a huge difference in my trip as I am a 6ft tall woman who is all legs."
Cons: "It was slightly turbulent and TSA at O'hare airport are the rudest and laziest humans on the planet."
Pros: "Snacks and drink"
Cons: "Average"
Pros: "Flight was on time."
Cons: "Seats are uncomfortable and cramped."
Cons: "The pilot's landing was way too fast. I was sure that the plane would come to a stop in Hwy 280 at the end of the Asheville runway. That plane probably needed a major brake job after that landing. We ended up at the absolute very end of the runway!"
Pros: "Wasn't thrown off"
Cons: "Another delayed flight with United"
Cons: "They might as well have thrown us in a car trunk the crew was very unaccommodating they didn't really care about us and the room legroom is ridiculously smal. On the connecting flight, the last flight the plane was two thirds empty and the crew made us sit in our assigned seats, crammed together telling us that if we want to sit in a seat with more legroom we have to pay $180"
Cons: "Too many seats too close together. The entire trip was too hot and stuffy. The flight attendants showed minimal care about the uncomfortable hot and stuffy environment."
Cons: "The United mobile app as well as my emails stated that the gate was B3. Upon arriving at gate B3 and attempting to board, I was alerted that I was at the incorrect gate. The gate was switched to C11. However, my app did not alert me nore did it reflect the gate change. I didn't receive a text or email update. I had to run to the different concourse nearly missing the fling."
Pros: "Crew was lovely."
Cons: "Seats BARELY reclined, and leg room was minimal. The whole flight was very uncomfortable even for someone who's only 5'3" who flys regularly. Also, no in flight entertainment for a long flight. Total fail."
Cons: "Turbulence was insane"
Pros: "We'll coordinated."
Cons: "The seats were terribly uncomfortable (including her flight to Chicago). The cushion made me slide down the seat and could not get comfortable."
Pros: "My flight in was smooth, seamless and amazing. The crew was so lovely."
Cons: "My flight out was a shot show that included a four hour delay and frantic running to gate changes. The staff was very unhelpful. The snack was awful."
Cons: "I went on this trip as an veterinary humanitarian out reach. I was also guardian to one high school student so that she might have an experience of such to guild her future. Her flight was missed booked to leave after mine, I attempted to rebook my flight with Luthansia but they would not let me me even partial rebook. I attempted a number of times to rebook the flight but their solution was extreme financial gain for them when more reasonable alternative could have been arranged. They canceled my entire return flight and left me stranded. I had to piece together a return flight on a shoe string budget. Thankfully American Airlines was understanding for it appears Luthansia and United are not."
Pros: "In flight entertainment worked. Staff was friendly."
Cons: "I had no issue with the delay, things happen. I was dealing with a knee injury and the gate plan had us all over the airport. It was quite frustrating to get to a gate in another terminal only to get told we were being moved back to the terminal we had just come from! Then that gate was changed again, involving another long walk on said bad knee!"
Pros: "The promptness on the flight -the friendly crew - arriving on time means the most, also the flight itself was smooth"
Cons: "There were no ticketing agents at the gate adding an hour to the flight."
Cons: "2.5 hour delay. No working bathrooms. Couldn't hear the tv and headphones that they gave out were useless."
Pros: "The crew was awesome and the flight wasn't bad at all"
Cons: "It was suggested that I didn't bring my carry on with me so I left it to be voluntarily checked and it came back ripped"
Cons: "flight was delayed for over 5 hours and gate was changed over 6 times"
Pros: "Over all it was a great flight aside from the rain delay but that's Mother Nature for you"
Cons: "Flight was delayed due to severl technical issues. Crew at least offer free drinks or snacks for the five hour delay."
Pros: "Nice clean planes and seat, on time performance"
Cons: "The flight attendant was hard to understand"
Pros: "Nothing"
Cons: "I was angry that I had to fly to Houston before heading to Phoenix which made my arrival in AZ much later than I had planned. My flight had been rescheduled since I missed my flight the night before because the first flight had been delayed. So the new flight was a longer trip because of the extra layover. The overall flight was a mess."
Pros: "Nothing"
Cons: "Multiple delays and gate changes; chaotic boarding; shabby plane condition (bathroom looked held together with duct tape)."
Pros: "That the plane actually took off and landed fine."
Cons: "Flight delayed almost 2 hours. I booked this flight on this airline as my previous flight on a different airline was delayed over 7 hours."
Pros: "Nice crew and boarding staff. The plane was repaired rather than the flight being cancelled."
Cons: "No airconditioning on the ground so the extra time on the tarmac was very uncomfortable. While taxiing, a screen went blank, so the plane returned to the terminal, deplaned, and there was a two hour delay for the repair."
Pros: "Tons of food and water. Movies good. Staff on plane were excellent. Clean bathrooms and peacful. Nice that headphones were provided."
Cons: "Seats should not be set to go back so far, if a person in front sets back all way, no space passenger behind. The seats should be calibrated to go back less of an angle."
Cons: "Some inspector idiot decided that the exterior cover stickers weren't "up to code" literally half an hour before my flight, delaying us 2 hours. I got onto a different flight at the last second, then the same thing happened to that plane. Brilliant on their parts. I almost lost a job interview thanks to your people."
Cons: "Boarding went quickly but then waited almost 35 minutes on the plane to take off. Once the plane landed there was again a wait to pull into the gate. Spent more time waiting on the plane than the flight itself."
Cons: "This flight was also delayed. It was bade enough the first flight was delayed almost an hour, but this flight also left late from the gate."
