Pros: "Comodidad en el avión"
Cons: "Hay desorden en la coordinación de los vuelos, atrasos, yo tuve un atraso de 11 horas, otros perdieron conexión, y no es tampoco porque se paga barato, porque los pasajes están caros"

Cons: "Food"
Pros: "The food and the crew"

Cons: "None"
Cons: "Flight was canceled due to United's mismanagement of crews."
Pros: "Clean, comfortable and on time."
Cons: "Nothing"
Cons: "No screens in the seats. Food options are the usual limited fair"
Cons: "I’m 6’3, misty in my legs, so the diminishing legroom is a problem. Can’t afford business class either. You should really have entertainment for a 5 hr flight."
Pros: "Comfortable seats with screens"
Cons: "Mediocre snack"
Cons: "I didn't get to get on the flight."
Cons: "Slow boarding, no food no drinks, no tv."
Cons: "everything"
Pros: "On time"
Cons: "In flight entertainment did not work"
Pros: "The crew on board was very nice."
Cons: "The Flight itinerary said Swiss Airlines but it was actually United Airlines. I almost missed my flight. How is this possible."
Pros: "Nothing"
Pros: "Más espacio, al menos una película que ver, y algún bocadillo por ser un vuelo de tantas horas"
Pros: "The pilot"
Cons: "Everything else"
Pros: "It was cheap"
Cons: "Customer attention, they wanted 50.000 lb not a bit above otherwise is US$200!"
Pros: "The staff were friendly and the movie choices were good"
Cons: "The seats were pretty tight and there were only pretzel snacks"
Pros: "Fantastic service. Much obliged for everything"
Pros: "Entertainment worked on this flight! And once again, I had an empty seat next to me - that's always a huge plus so I can stretch a bit."
Pros: "The flight crew was very attentive and friendly. Probably one of the nicest crews I have encountered on my flights."
Cons: "Me and this other person were waiting in the back for the two bathrooms to become available. We waited over 10 minutes."
Pros: "The plane took two hours to leave the ground due to weather. This was unfortunate and made the passengers uncomfortable but it was not the fault of the airline."
Cons: "The airline gave all the passengers access to the movies and television channels."
Cons: "My luggage didn't make connnection."
Pros: "So they lost my bag but where super helpful and nice!"
Pros: "Getting off the plane"
Cons: "Everything was cramped- not enough space to move. They completely ran out of overhead space. Completely crazy"
Pros: "First flight delayed once board to check a broken light. Then waisted 40 minutes taxiing on tarmac in Houston because they couldn't find a gate. Missed our connection. They put us up in a low end hotel overnight. Then we had our morning flight again delayed as we waited for planes to the take off, so further delays. Arrived in Costa Rica 1 hour late. Now with too many other flights so immigration packed and took another hour and twenty minutes (when we finished there was only a 5 minute wait). Thanks United"
Cons: "Coffee and cookies. Moscow mule"
Cons: "Snack offering was caramely sugar cookie"
Cons: "Flight was delayed for 4 hours due to airplane maintenance"
Cons: "Fligh delay."
Pros: "I was allowed to get off the aircraft to collect a bag I left behind"
Pros: "Attendants were amazing"
Cons: "We spent the whole delay on the plane and wasn't notified of a problem until after an hour. A lot of my time was wasted. That's not okay. Keep your customers informed."
Pros: "The boarding process is terrible, because communication breakdown is inevitable. The crew on the plane are sometimes rude, and have no patience when passing seated passengers. One air hostess constantly bumped into my arm like a bull as she passed walking down the isle. Entertainment is practically non-existent on long flights unless you pay for it. Two of my flights were cancelled last minute with little to no remorse, and I had to wait 2 days to catch the next flight. That flight was even delayed more than an hour. I was sick by time I reached my destination. Overall, United would not be my 1st choice due to bad experiences numerous times."
Pros: "Since we were the last ones to arrive at the gate because of our delayed flight they had to check our carry-on baggage with the luggage we didn't have locks and nomally what we carry in that bag are fragile or valuable things. They should at least have plastic gauzes or fragile stickers to put on the bags. I don't know the reason but the flight attendants left about the last 6 rows of passengers without pretzels or drinks. There was no device to view movies. Leg space too tight."
Pros: "Nice and comfy seats, good service on plane, fast boarding"
Cons: "No good food and the entertainment was not the beat"
Pros: "Just the crew"
Cons: "Now when I fly united i feel like flying with spirit or jet blue o any other cheap airline, they charge for everything but sodas. They don't even carry blankets. The fact that for a long (3h- 4h and 5h) flight (took 4 overall during the holidays) united didn't offered ONE movie for free at least was very disappointing. Not one of my flights were on-time!"
Cons: "Same. No ffood ..poor Service and allso charging. To much for extra weight. $200 for 3 extra pounds. Ridiculous. Also charged for one check in bag..Todo much"
Cons: "Viajar en United es desastroso. Los asientos son demasiado pequeños, yo mido1.57 metros y no me podía ni mover."
Pros: "The crew were nice though exasperated with cramped new planes and crowded restrooms. Flight was on time"
Cons: "After three years of flying all around US, realized United is the worst of the three major legacy carriers. I'm star alliance gold and it's still a painful experience. Crew admitted in latest redesign of planes they've managed to squeeze another six seats in coach. My seat wouldn't go back but even if it did, would feel too guilty for person behind to do it - so little legroom on newer planes. They've also cut down on restrooms so for most of the flight there was a line of 5-6 people waiting in the aisle. American Airlines seems to have older planes but at least decent legroom (and I'm not tall - anybody over 5'10 would have to sit at an angle on new United planes!). Been very impressed by Delta's service lately. United feels more like Spirit"
Pros: "I liked that I was given spacious accommodations for myself and my service animal."
Cons: "I didn't like that we then sat on the plane for 2 hours, then had to get back off. I don't really blame United Airlines for this because there was a storm. But if Kayak wants me to rate the flight I'd have to say it was bad because it didn't even occur."
Pros: "It was nice"
Cons: "Emergency landing with no power in flightn"
Pros: "The staff was really polite and were willig to answer all questions with a smile."
Cons: "The seat I was on could not be reclined. This was most unpleasant because it was an overnight flight. You should earn the clients - even economy passengers - when this seat is the one being assigned to them. I would payed beforehand to get a more comfortable seat if I'd known I was to fly on a no-reclining seat on an overnight flight."
Pros: "Nothing"
Cons: "They delayed the flight due to "operational difficulties". I understand this happens, however, their communication towards customers was unacceptable. They first announced a 20 min delay, followed by another 30 min, then 30 more and then 30 more than then 30 more! They basically kept us at the gate for 2 1/2 hours until the found another plane. For a business like United, and flying out of their hub this is completely unacceptable. We ended up leaving at 11pm for a flight scheduled at 8. They didnt give anything in the plane to make up for it. No food, no free wifi, nothing."
Cons: "The refreshments should be better than a tiny packet of pretzels."
Pros: "The seat next to me was empty"
Cons: "United put my bags on the next flight to San Jose, so I had to wait an extra 2.5 hours in the airport for the next plane to land in San Jose, Costa Rica while my ride waited for me."
Cons: "The seats were so small, with no space between rows that you couldn't even recline. The tv on the seat in front was so close you couldn't watch it. Miserable flight, and I'm only 5'5"."
Pros: "Terrible"
Cons: "Everything"
Cons: "I felt like tuna in a can."
