Had one staff that was not pleasant. Seems they are stressed with too many people to care for.

Had one staff that was not pleasant. Seems they are stressed with too many people to care for.

I would have liked an opportunity to move to a different seat ( even would have checked in my hand luggage)as I had health issues where I didn't have to clamber over the passenger next to me to for toilet use/ movement [ She was a highly unpleasant neighbor to sit next to]. In addition, I found that my European phone plan had run out of data and so I was not receiving emails from yourselves on airport wifi to be able to check in online and verifications difficult as did not accept the ticket number I had. I asked for an extra blanket but was told there was none. Then I saw other passengers receiving them. I couldn't eat the food and asked for snacks : Stewardess said " on the way" but they did not bring. The best bit was the check in process in Lisbon. Very efficient. However, I did not understand why we had to collect our bags at Washington then go through customs again. It was not explained. I also with my leg and health issue had approximately mile walk to the gate ( which then changed) . There appeared to be no moving walkways or help provided.

The attendant were friendly. I suggest you have a medical attendant on board every flight so that in case someone is sick , he/she will help them.

We had a very long diversion and our food voucher didn’t work because the restaurants were closed

United airlines, mediocre at best. No issues , nothing great . Worked for me

Turbulent taking off & landing to Dulles from Raleigh. Flight from Dulles to Tokyo very good!!

Very nice and clean plane. Transit time between flights was tight though

Mostly the experience was good except for the flight changes made by UA which meant longer layover in DC

Terrible. First of all we were delayed 4 3/4 hours departing Honolulu. As we had to leave our condo and the rental car had to be returned we had to go to the airport. Even though we had a business class boarding pass to Washington, since we did not have business class to Montreal we could not access the lounge without paying a $59 fee each. This does not make sense to us. Since we could not meet our original connection United booked us to Montreal via New York LaGuardia on Air Canada. In Washington a further delay got us into LaGuardia too late to make our connection to Montreal so we were booked on another Air Canada flight 3 hours later. We were originally scheduled to arrive in Montreal at 10:40 and arrived at 19:55. A totally exhausting day, United did not offer a meal voucher or any type of compensation. Air Canada did give us a digital meal voucher. The food in United business class is poor among all meals offered. The pods look nice but are not that confortable. Overall would not fly on United again.

Change cabin crew assisting business class. Not taking care, ignoring requests and calls. Never had such an experience in business class.

We had to turn around and head back to Manchester. Problem with a plane engine.

Flight was delayed. Staff at the gate effectively and proactively communicated about the delay.

Very poor delay in dfw was really bad n long

Our flight was 1.5 hours delayed. There was no weather for the inbound flight, so I don't understand why. This meant a VERY late arrival and only a quick nap before my morning flight.

Because of rescheduling, they had to put me on a flight that didn't go through Dallas

It was very difficult to stretch my knee out and I am very short. I also had a torn tendon in my knee which made it extra uncomfortable anyways. My husband is 6'2" and I can't imagine him flying in that plane.

3 hour weather delay followed by 1 hour (and counting) maintenance delay. UGH!

After we'd boarded , they canceled the flight. The crew didn't even know , we just all received text messages. Then after they deplaned us , AA was just like "too bad, go F your self, we sure ain't gonna help you"

Initial flight was cancelled at the time of arrival to the airport, flight alternative requires switching from direct to flight with a layover, and the plane felt like it would split apart, it was so rattle-y.

Weather delay for 2.5 hours followed by half hour crew delay, did not have ginger ale, uncomfortable seats
