Checking in united could not figure out my star alliance gold. Baggage did not get marked priority and didn't receive boarding passes. When got to SFO lounge personal fixed everything Immediately

Meals were poor and service rendered on return flight was mediocre as compared to the flight we took to Germany earlier where the attendants were more attentive, energetic, and mindful of passengers' needs. Thumbs up to crew of UA 58. Thumbs down to UA 59..

Flight left on time, arrived early, pleasant staff provided water, coffee, etc. access to bathrooms was reasonable and were well maintained. blankets were available, lots of entertainment options. LUGGAGE SERVICE WAS GREAT. I got my one checked bag quickly and was able to make a bus connection for a 2 hour bus ride saving me from waiting another 1.5 hours.

Terrible, if possible won't be flying again anytime soon!

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.

Was never allowed on and not refunded the full amount of the ticket plus charged a $300 processing fee.

Terrible. Our flight was completely cancelled with no options to rebook until 4 days later.

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

Excellent service. The crew goes above their way to make the customer comfortable.

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

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.
