Entertainment center did not work and no electric available at seat for 11 hour flight. Didn’t have access to overhead light or call button. Food was tasteless and had a high salt (27 %) of recommended daily salt intake

What would be infinitely better if for Kayak to not offer this flight as if it was completely different airlines rather than United and then filtering me through some creepy discount site.

Our flight gor canceled and there was no one to help us but told us to scan the qr code and fill the forms on-line. Very poor service especially we are tourists traveling to Washington DC for the 1st time.

Our flight was great with an unexpected upgrade. However, four days into our travel we are still without a piece of luggage. The bag tracker has not been accurate, the airline is not communicating with me or the luggage delivery service and no one is willing to take responsibility or guarantee any kind of support or reimbursement. Unfortunately, we do not have the option to easily shop to replace items as we are currently on a cruise. I have been very disappointed by United Airlines response.

The flight was canceled. I couldn't get on another flight. Meal voucher wouldn't work. The whole experience was a clusterfuck.

It was terribly delayed with zero support from united airlines. I reached at 1 am in the night. They did not provide any option to change the flights.

Flight attendants were friendly & good service, food sucks, seats uncomfortable, not many Asian movies or shows flying from Hong Kong

I needed to make changes to my flights. When I called customer service, they assisted me with care professionalism.

I found that it seems that the space for personal bags or luggage is not enough( the cabinets for personal bags or luggage over the seats) .

The service was non existent . Crew did very little didn’t even answer call button . Premium economy in this long haul was the worst I have ever experienced . Never again flying with them .
