The flight from Hanoi to Korea got delayed so we have to fly with Asian Anna instead. The checking took so long and confusing. We barely made the flight from Hanoi to Korea and ran from different terminals to catch the flight from Korea to New York. We paid extra to select seat to sit to gether but then we found out it was just a joke to get money from Justfly since Korean Air said they only arranged seat at check in which we couldn’t check in as early as we wished due to the delay. And from Korea to New York, they lost our 4 luggages. How horrible could that be ? We are thinking about suing justly."

Pros: "Business seats were excellent"
Cons: "All was good!"
Cons: "Boarding at Singapore airport was shocking, as we had to wait 6 hours for our flight. Rating low to the crew mainly because of the ground staff as they were not very communicative to begin with about the explanation for our delay. Only when the passengers got a bit more vocal about wanting explanations, they started giving us a bit more information. All estimated times given for boarding the flight were incorrect by a big margin! Seemed more like they were giving shorter wait time for boarding just to please the passengers, where as they were well aware of how long the wait would be."
Pros: "The seats seem to have more leg room, food was actually good, and the staff was delightful."
Cons: "It was a 17 hour flight, but they made it bearable."
Pros: "Modern aircraft , nice crew"
Cons: "Long haul airlines across Atlantic charging people for drinks and food on flights !! Best call yourself as cheap budget airlines and stop the pretence . Would be useful if this information was shared at booking plus “drip cost feeding” policy is appalling! Frequent traveller and have never seen such an appalling behaviour on long haul airlines"

Cons: "Service is dismal and run down interior. Rips in seats. Lags way behind Asian or certain European airlines"
Cons: "United Airlines in our experience runs late putting a lot of pressure on any ongoing connections . Not clean . Staff not friendly . Only sometimes helpful."
Pros: "Came close to missing flight because of gate delay because of connecting flight, but one of the flight attendants saw I was flustered and sweaty and gave me a cup of water before the flight even took off. Very thoughtful and nice."
Pros: "It was a pretty good flight. Everything was great other than I felt very rushed and felt like I bothered the flight attendant when I asked for sugar with my tea. I tried to ask for a stir stick with my sugar but she had already moved on. The flight was also very cold."
Cons: "The temperature could have been warmer (i had pants and 4 shirts on and still felt cold). I also felt like I was rushed and unable to get all the items I needed with my tea from the female flight attendant."
Cons: "Stop pretending I can take a carry on. I'm boarding last, and guaranteed I'm going to have to check my carry-on."

Pros: "This plane has more space than larger plane, was more comfortable."
Cons: "The seats are getting smaller and the leg space is nonexistent."
Pros: "The crews did a great job!"

Cons: "Going and coming back was delayed"
Pros: "For all the turbulence that we heard about, the flight was extremely smooth which I attribute to the pilot's skills"
Cons: "We kept on being told that there was going to be turbulence and that it would be too rocky to serve food/drinks - but there was limited turbulence and the flight was very smooth. There was also a delay in leaving as there was an extra bag in hold but they 'couldn't find it'."
Pros: "Flight was nice and empty"
Pros: "After United lost our luggage in Houston we had to file a claim in Auckland which meant we missed our flight to Wellington. Ground crew were super helpful and got us on the next flight 30 mins later. Cabin crew were great and sorted us out with water and snacks before take off as could tell we were desperate after flying in from London via Houston."
Pros: "Everyone was nice, and the flight was on time. Checked in with the app and just a carry on, so my day was hassle free."
Cons: "Can't really think of anything. It was a good flight."
Pros: "The plane was new"
Cons: "Flight was switched to United airlines so the confirmation number did not work and we could not check in on line. Food was the worst I have had on a flight."
Cons: "after boarding, we sat on at the gate for nearly 30 minutes without any explanation given. When announcements were made the person's language skills were greatly lacking - we could not understand anything that was said. there is no food, drink, or entertainment... unless you consider the man behind me playing with is cat .... and yes I'm very allergic :( landing crew didn't know where our luggage was to be returned (bottom of the gate or top of the gate). After a considerable time, we were told all luggage was delivered to the baggage concourse."
Pros: "Check in was very good Both Outward and Return flights were on time. Crew very attentive Seating not too bad (if you haven't got long legs)"
Cons: "Food could be a bit more varied - some people don't like pasta and some people don't like chicken - what was left????? Should have different entertainment on different legs of the journey Not really Flight-related but Passport Control in US could do with a review .... waiting a good hour or so - come stations were empty and those that weren't the staff were changing shifts while there was still loads of people to go through - not nice when you have people meeting you."
Pros: "Flight crew was very nice Seats were comfortable"
Pros: "The bathroom sign that shows if it is busy without going there"
Pros: "United seems to have simplified how it separates the boarding groups, so getting on the plane was well organized. The 787 aircraft was spacious and comfortable, which seems to put both passengers and crew in a good mood. Lots of entertainment options were available, so the three hour flight flew by. And we arrived early! A great experience on United."
Pros: "Service at business was good. Comfortable chairs and quiet cabin space."
Cons: "The gate experience due to long time between flights getting worst due to a departure delay."
Cons: "Delayed flight caused missed connection. Auto booked on late flight next day and had to change airlines to get better times. Voucher given for hotel off airport and shuttle never arrived and had to take Uber. Hotel very low quality."
Pros: "Boarding went smoothly and there was overhead space for my big backpack. Attendants were nice."
Cons: "We received drinks twice but never got snacks. A bit of food during a long early morning flight like this would have been very welcome."
Pros: "Awesome Plane and flight"
Pros: "Good trip and on time"
Pros: "The leg room and comfort in economy, for a 767, were surprisingly good but the quality of screen and entertainment was lacking. The screen on my iPhone is bigger than the screen on the seatback which if compared to other airlines is not up to the mark. The lack of facilities to charge things like ipads or iPhone was disappointing."
Cons: "The seat comfort was good as was the legroom in economy. The crew were friendly and helpful and I found the overall experience good. If Unitied could build on that and just offer power (even usb) and larger screens they would be onto a winner."
Pros: "Cost On time"
Cons: "Seats in the last row."
Pros: "Efficient boarding, early departure. Early arrival"
Cons: "Spotty internet, somewhat limited entertainment."
Pros: "We had turbulence at about 37,000 feet so the pilot took the plane up to about 39,000 feet so that made the flight smoother. We arrived 16 minutes early"
Pros: "Very comfortable flight"
Pros: "WiFi and entertainment on board the aircraft"
Cons: "All goof"
Pros: "Decent flight, can’t complain, pretty much empty."
Cons: "laberithine process to get my boarding pass. Booked on Kayak with last minute on a Luthanasa flight operated by United. Basically had to call all three in order to get my boarding passes as the website didn’t work. Really confusing."
Pros: "all smooth"
Pros: "Not a lot to say really from a positive, In Europe if we had to fly over 4 hours the airlines put on larger planes, this plane was small for a 6+ flight"
Cons: "Small plane for a 6+ hour flight, food is . sub standard, if you want to watch the onboard entertainment you need to do so from you phone or Ipad, you need their app installed first and flash player, if not your screwed. They allow you to download their flash player but it does not work."
Pros: "Fast boarding"
Cons: "Plane was a little drafty."
Pros: "On Time"
Cons: "Dear United crew, there are definitely a bunch of great people amongst you. Can you please tell your fellow colleagues to start treating passengers as customers ... no need to leave your good spirits at home, just bring it on the plane ... starting with a smile! And yes, in seat power was not working. PS I wonder who decided on the power outlet placement ... 1.5M flying miles on United."
Cons: "Very cramped with staff who I found overbearing. Not the most pleasant experience."
Pros: "Nothing really everyhing was mediocre."
Cons: "Delayed baggage, smelly flight, food"
Pros: "Service was terrific."
Pros: "on time, got the seat I wanted"
Cons: "steward was somewhat aggressive, but was responsive one on one. Focus on size of carry on baggage was anxiety producing."
Pros: "Plane was a lot cleaner than I’ve been accustomed to. Boarding was great."
Cons: "I want real food on 4 hour flights where there’s only 1 hour between connections. Starving from 4am pacific to 5pm eastern time is not good for my blood glucose levels. Salt and gluten laden over priced snacks are not good enough"
