Flight was kept super cold. I was shivering and had to layer up.

Everything and everyone were excellent except for the charge for using WiFi; there was no escape from this fee except to not use it.

The crew and the food were excellent. The plane was kept quite clean.

Crew were not engaging. Only engaged if requested. Food taste was mediocre

My seat had many issues. First the chair was broken where reclining was difficult. My usb plug was also broken so charging was impossible.

The flight from Hong Kong to Hyderabad didn’t have any power points to charge my mobile. Given we are no longer allowed to use power banks, giving customers the ability to charge even on short flights is critical part of the overall experience.

when i ask for help all the crew members had a look like why are you calling me? very terse and rude.

Good service and food. However, we paid over $400 for aisle seats for my disabled husband and me, and we were given window and middle seats. This was dangerous for our health condition on such a long flight. We needed to stand up and walk around frequently, but we were stuck in our seats. Please give us a refund of our seat payment since you chose not to honor our request.

Very bad Instead 22 hour it take me more that 35 hour to arrive from Los Angeles to Phuket and they changed my flight in Hong Kong to Shanghai china and in order to get my bag I was forced to vet china visa entrry

There could have been more options on the entertainment section Nothing was available for non English speaking passengers

Some crew were unfriendly or in some cases just straight up rude.

Booked through Kayak Business, had a seat in middle and towards back due to booking rate, not comfortable.

Was great in general, try to respect time and excuses when slight changes have been made, appreciated!

A long delay. Don't travel late in the day.

Super friendly with lots of drink options an entertainment. Friendly crew.

Standard flight with a drinks and a snack- overall very quick flight. The flight attendants were very strict, bordered on rude.

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

United Airline crews were very friendly and very attentive. 12 hours flight was gone like in a shorter one.

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

Food was surprisingly delicious. Space in the seat is horrible when the seating front is reclined. Movie offerings were terrible. Crew was friendly and helpful.
