This flight was leg 2 of 2 leg journey. The staff at baggage re-drop in Tokyo were fabulous. Once at gate when time to board, had to take standing room bus to the tarmac to board. Did not like getting out to plane and having to wait 5 minutes until they opened bus door.

This flight was leg 2 of 2 leg journey. The staff at baggage re-drop in Tokyo were fabulous. Once at gate when time to board, had to take standing room bus to the tarmac to board. Did not like getting out to plane and having to wait 5 minutes until they opened bus door.

Website from the 1990s, super frustrating customer support, inflight experience merely OK - more like United than e.g. Emirates

The seats are significantly more comfortable than US airlines and the staff are much friendlier. The food is also much better, as they are particularly accommodating to any dietary restrictions.

The team members are extremely attentive to make sure you have the best experience.

Could had been better if they include in their menu some western food.

They 7 seats in one row for Business class while most business class for other airlines are 4 seats in one row. the seat was narrow. the Toilet was so smell, dimming light, no water out of faucet. Terrible.

Difficult to access advanced check-in online. No way to understand why it wouldn’t work. Call center not answering. Email for answers took days to respond, Kind service at the airport and on the flight made up for disappointing service before flight.

Courteous and helpful employees. Comfortable seats and temperature of aircraft . Did not need squid in my salad but glad to have the menu information advising me of what it was

Everything was great, except the Wifi, but that's understandable.

The plane was dirty, there was trash in the seat pocket in front of me.

Uh there was a delay, because of the weather. And what took usually an hour flight to Louisville took about 6+ hours. Flight got canceled

There wasn't much entertainment for my short flight but the onboarding process was smooth and the crew provided wonderful service. The seats were also reasonably comfy. Great flight.

I had to get rerouted because the weather delayed my flight enough to miss both of my connecting flights. I select nearly 2 hours on customer service trying to get rerouted and had to miss my first plane which took my luggage to San Francisco. Luckily, customer service sent me to the same airport but I had to ride 12 hours in economy after I paid extra for premium economy. Totally sucks that I overpaid. Customer service and airplane crew were great and really helpful though. Although I still hate how small the seat was, especially since I'm smaller than average, I can't imagine how much it would suck for an average sized person.

Flight attendant took good care of my mom as she boarded on and off the aircraft from her wheelchair. I did not care much for the food nor the movie options Available. I appreciated the increased legroom available in economy. This was one of the main reasons we chose the airline. Overall, the good value and I would fly again.

I stopped flying with United back in the nineties. Today's experience reminded me of why.

ANA was fine. LAX has some major problems. I needed a wheelchair and BKK and Narita were very good. I do have to remember NOT to tip in Japan. LAX however, was poor. first the attendant wasn't able to push me. The next person left me stranded in several locations. They would just leave me where ever they felt like; No logic to these locations. finally when we cleared immigration, they (there were several people who didn't seem to care about their job) left me in a large room with a baggage carousal. I tried to locate my luggage to no avail. meanwhile my connection was getting closer. I finally talked with Emir from ANA and he showed me to my carousal which was located a few rooms away from where LAX personnel stranded me. Emir also found a good wheelchair attendant to take me the rest of the way. Without Emir from ANA, I would still be stranded, given the amount of care shown by the first wheelchair attendants.

Wonderfully pleasant experience. Good meal and beverage selections. Professional air staff.

Seat width can be a bit wider. not nice that they charge extra for the window seats.

I was very happy with my flight on ANA. The crew were excellent and very helpful throughout the flight. The food was also very good. The seats were comfortable and had excellent legroom. The headphone jack position was annoying, but that is a minor nitpick. The movie selection in the IFE was good, but the TV selection was lacking. Adding English subtitles to the Japanese movies and videos would have been very useful.

Wonderful. I love ANA airlines. It's the best so far. My first pick when I travel now.

Food choices were very limited. Taste of the dishes was average.

I liked all the informational texts. I always knew where to go and when .

Not as good as expected Air Can needs to improve totally rated on internet as worst

Received an email the night before showing that there would be seatback entertainment on our flight. We get on and there was no seatback entertainment. And then it was a scramble to try to set up the iPads for the kids before takeoff so they could watch something for the four hour flight.

The reason I don’t fly United. No in seat entertainment for a long flight and inconsistent WiFi and entertainment available from my device.

It was 4 hours late. Almost missed my connecting flight no food or drinks on connecting flight. Overall terrible experience

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

The food for long haul was poor compared to Singapore airlines economy. Pasta plain with tomato sauce . Singapore airlines give me Hagen dash small ice cream cup it was great. The choices of dinner course Singapore air also much better The crew mostly friendly. The economy seat are as expected.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

I was at the back of the plane with earphones, and I could still hear the chatty flight attendants; I wasn't able to sleep at all.

Boarding was challenging as we had to use the stairs from the tarmac. Stairs are okay but a roller bag makes it challenging.

Ensure prepaid food arrangements are appropriately understood by flight crew of who purchased and who did not

All was fine. Weather was a bit stormy, but nothing kayak can do about that! 😊

I paid for a comfort class seat and was seated in economy.

Once again our Air Canada flight was delayed! I'm hopeful competition arrives with other airlines soon and maybe they will make a better effort to be on time!

My plane was cancelled and had to be rebook for the evening was not happy.

The flight was cancelled and we had to rebook on Porter to make our cruise the next day. Air Canada has not compensated. We won’t be flying with them again. This is the second time this has happened. Also the return flight was delayed 2 hours who knows why.

Mixed experienced. Nice staff. Spacious 787 better than cramped Airbus, though my seat was broken. The bad: Way overpriced ticket and charged for food despite 6 hr flight.

Separated me and my wife and wife’s sister in far apart different seats even though I booked them all together. Just scams after scams to make us pay more. Worst airline

Very smooth flight and the crew members were very welcoming.
