Wonderful in-seat entertainment with seatback screens and huge selection of quality movies. The ability to bluetooth connect headphones was amazing.

Wonderful in-seat entertainment with seatback screens and huge selection of quality movies. The ability to bluetooth connect headphones was amazing.

we did a return flight from Paris CDG to SFO. This trip was much better than the departing flight SFO to CDG. The food was better quality, the crew was nicer, and the interior of the plane seemed cleaner.

Horrible service no Wi-Fi connection on both leg of the flight and they are refusing to fix bad service

We got to get extended leg room in Econ plus that was great. It was nice having our own dietary needs met with our meals, and the connecting flights had it as well. Only negative were the seats my bottom was/is really sore after a ten plus hour flight. Those seats are horrible, understandable for as many people use them. So we are going to purchase a gel seat pad.

Flight to Japan was was better across the board than the return to USA. Entertainment: Movie selection was old and not to my liking. Way too many woke choices. Not enough selections for sports or drama. Service: some of the crew were great. Not all. I paid for business class. a premium. Some of the crew thought they 'had' t do there job instead of wanting to serve and be polite. Food: Way to Japan was good. Way back to USA bad. Boarding: Wat out did not offer Business only; had to go thru general. If you pay for business, you should get business perks. Suggest you look for other than United for travel to Asia

I will never fly ANA again. They lost one of my large pieces of checked luggage, the heaviest one with the most valuable items in it, and they said they will not send me an email unless they can't find it, even though the paper they gave me to track the status of my lost luggage requires a code from an email they are supposed to send me so I can do baggage tracing. They claim to be an international airline, but they also insist on calling a Japanese telephone number to confirm where to send the lost baggage if they find it. It is impossible to find an actual contact email address for customer support on their website, and their AI chatbot is unhelpful, directing you to a webpage that says it is for contact information but does not have any actual email addresses or phone numbers listed on it. My seat in economy did not recline at all, even though I was not sitting in an exit row nor the very back row. I had to sit in the fully upright position for over ten hours of international travel. Awful experience overall.

The head flight attendant made the trip excellent. He was very accommodating.

The economy seats on the 777 was not as cramped as I had feared, but the food was terrible.

Terrible experience! delay 2 time and say i dont have ticket

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

Generally good. Not their fault but the design of the Boeing 747 had seating supports directly in line with my legs. So my legs always had to straddle this support which caused body misallignment. Such poor design from Boeing. There was no USB port for me to charge my phone. The screen touch control was very poor.

I like crew. They are friendly. The flight was delayed to take off for 1hr and that caused panic at Houston Airport to catch connecting flight due to security check delay. If it has reached on time I would have sufficient time in collecting bags and security check

How about changing the personal out to more friendly human beings? This team was pretty arrogant. No fun!!

Everything could have been better. What needed to be wrong with United went wrong

Patrick and the whole crew were amazing! Hope to have this team for all my European trips.

This review is based on 2 things: 1. The lack of hygiene on the plane. 2. William - the head flight attendant. The lack of cleanliness on the plane upon arrival was appalling. Being given a sanitizing wipe upon boarding of the plane is shocking when you consider the cost of a business class flight. UA expects me to do their job and clean all the bread, food and debris left from previous guests. Does this sound normal to you. The seat, the food table and the sides were full of crumbs, chocolate and dirt. When I told the flight attendant they just gave me more wipes so I could clean it myself. Secondly, William the business cabin head flight attendant was so busy flirting with a couple in the front that his attention to the other guests was minimal. He continuously asked them if they were ok or if they needed anything and it didn’t matter if the rest of us needed anything. And if you are the lead attendant shouldn’t you be checking if the bathrooms in business class are clean and needing toilet paper. There were 2 bathrooms in business. Halfway through the flight the first bathroom was closed and the second bathroom was dirty and had no toilet paper one hour and a half before the flight landed. He needs additional training on prioritizing things. He should care less about flirting and more about his work

Smooth flight with enough time for connection. Ran out of meal options. In-flight and gate staff were friendly and helpful. Good service overall.

They don’t give information on why a flight is delayed in a timely manner. Very frustrating.

The plane (Mitsubishi CRJ) felt old, creaking and not very new. The crew was okay. Hot water provision was broken so hot beverages could't be served.

Liked the flight being almost on time (airport issues created a delay). Disliked the issue printing tag bags on the kiosk and having to wait for an hour on like to drop my bags.
