SEA HND sector internet only worked for the last 2.5hrs of flight….. never had this kind of incident with other airlines

12 of the 14 hours were in the dark, all during daylight. Didn’t use my light because it disturbed other people it was illuminating. 14 hours sitting upright in a cramped space was horrible.

I’ve always had pleasant experiences with ANA and that has made me a loyal customer.

UA discouraged people to choose seat on economy class by charging about three times of another airlines. For example, ANA will charge USD60 to choose an aisle seat but UA is charging USD 219.

Roomy airlines. Friendly staff. Timely service. Temp was warm during the flight.

As usual the flight from AUS in Austin to SFO was late because they didn’t have adequate staffing to board the plane on time creating a 1 hour delay, which resulted in me missing my flight to Osaka due to a missed connection. When I got to the gate 10 minutes late after landing exactly the time the connecting flight was taking off, I saw my flight to Osaka sitting at the gate and that gates had closed. I attempted to contact United Via chat on the United App and was given the runaround and passed between 2 separate “agents” who after saying they could rebook me, told me I needed to go to ANA even though they’re partners and all of my ticketing was through United. After going to ANA’s gate at SFO to try and get help I was told I would need to leave and go to United’s ticket counter in order to get help. The ANA agents said that it was United’s issue. An hour after running to try to make my flight I got to the United counter. I showed the agent my itinerary and she helped as much as she could. I was booked on a flight that would occur 13 hours after my original flight to Osaka and given $45 in vouchers which doesn’t cover much at SFO. I had also spent 30000 miles with United to get an upgrade with more legroom. And that was not refunded to this point. Ultimately I lost 1 whole day of vacation in with my wife and kids and, the 30000 airline miles and I’m out the money and time I spent. In these situations United and their partners should go out of their way to communicate and accommodate but I was left to my own devices to find the right resources. The only option was to fly to Seoul 12 hours and take a connecting flight to Osaka: I am a United Skyniles member and would not recommend booking a flight with them unless you thoroughly understand the routes as it is likely you will be left to your own devices to resolve the situation.

The food was terrible and totally inedible. If you are flying with ANA/United bring your own food it was a long flight to be hingry

Staff at gate and crew on plane efficient and friendly.

I thought I bought the ticket directly through Kayak not a 3rd party

I like that we made it faster than regularly scheduled. Everything else was poor. The boarding was slow and chaotic. One person was screaming instructions to people that didn’t understand and there was only one camera so boarding was slow. The crew was not very friendly and one stewardess was extremely rude to everyone the entire flight. The food was not good and not themed to the country we were going to like every international flight I’ve taken. Lastly the seats were awful. After this flight I would never recommend United and will actively avoid booking another flight through them.

Baggage claim signs were not updated with my flight information, so I had to guess. The app wasn't updated either.

I almost missed my connection in Chicago due to having to wait on a gate to be open I am assuming. Having to run from E terminal to C terminal and I barely made it there before they closed the door. This may not be the actual airline's fault it's crazy how there is so little time between flight especially when they are placed so far apart in the airport.

Unbelievably smooth boarding at IAH and the flight attendants were top notch.

We flew business fares. Was amazing. However, the check in didn't offer business fares preboarding which is less hectic. 8/10 due to this. Staff compared to Canadian carriers go above and beyond. Would gladly fly United again.

It was extremely hot in the cabin the entire flight, vent air was worn

1 flight cancelled Had to fly out of different city Flight at new departure city was delayed 3 hours causing us to miss connecting flights. By the time we did make it to Prague our luggage did not. Had to wait day and a half for luggage to be delivered. Customer service was not good. Agents did not arrive at gate until 5-10 minutes before boarding

It was better than excellent. The staff in Mason City were great. The young woman that pushed my wheelchair did more than could be expected of her. She came from India 17 years ago. I don't remember her name.

Very rough getting into denver. my kid threw up it was so rough.

Liked that we left on time for each flight. Snacks not the best, but we're okay.

I had requested wheelchair assistance prior to flight. The airport staff had no record of it. It was not provided at Cedar Rapids which was a small airport, so I managed on my own. At O'Hare airport the same thing happened. The staff told me they had no record of my request for a wheel chair. But they finally provided it after a delay when I insisted that I needed it.
