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.

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

Flight attendants had a little attitude. Food tastes no good.

Very disappointed with premier lounge. Food selection very poor, both coffee machines out of order. For the price you charge for an upgrade, the seats don’t fully recline, movie selection is old. Not very good value. Asian airlines are light years ahead at a more affordable price.

The stag were helpful, kind and liked the passengers. The plane was pristinely clean! Great flight!

The plane was delayed an hour. Heard from other passengers that the Vancouver connection to SFO was never on-time.

My experience was good with United too But only not so good thing was that at Calgary airport I was not given lounge access despite of flying business. Aspire lounge denied it to me, which was unfair I feel

The staff was great and made the long trip easy peasy!

The free Wi-fi for Aeroplan members was a great touch. The time passed quickly. I found the seats seemed a little closer together than I remember. Not Air Canada's fault, but we were about 20 minutes late landing because the airport was too busy. We had to circle around for a while. The boarding and disembarking went very smoothly.

It was great other than the plane was really small

The crew members were great. The flight was awesome. But I had trouble getting to any of the movies. I tried over and over. The free wifi though is a bonus which I appreciated. Re comfort I am not telling you anything you don’t know. There is nothing comfortable about air travel any longer. As someone with a back issue I am usually squirming about two hours into any flight. But safety matters most of all to me and I do feel safe with air Canada.

Had to cancel flight due to strike. Hope things will be better next August when we will rebook. Very disappointing as it was our 50th wedding anniversary celebration l!

I liked the behaviour of the crew members.The flight was good.
