Business class on ANA was awesome. There lie flat seats made it easier to sleep on a 12 hour flight. Food was great and service was excellent.

Business class on ANA was awesome. There lie flat seats made it easier to sleep on a 12 hour flight. Food was great and service was excellent.

The crew was very nice and polite. They made sure everybody got their meal and drinks. Even the economy class had a very adequate leg room for someone that is over 6 foot tall.

Overall it was good. Making changes to the reservation on ANA’s website was little challenging. Would like to see those features improved in the future.

The flight crew was outstanding. Very cheerful and always respectful. I wish the same could be said about United. The AC wasn't the best on the plane.

The seats are uncomfortable. The flight attendants are not pleasant. They do their job, but not with a ray of sunshine and warmth. The food was awful, not what I would expect from an Asian airline. All of the other Asian airlines I have flown have far better food. The food was on par with United airlines food, which is really bad. Maybe ANA should get out of the alliance with United.

During booking, I selected the seats so that my wife and I would sit next to each other. However, the airline changed our seats at boarding so that we were seated apart. Very disappointing.

Every leg of the flight was late causing us to miss our flight to Okinawa and have to take the next flight out.

One of the best 14 hour flights I've ever had. Crew was friendly throughout which can be difficult on longer flights. The crew being kind and respectful is very important for me. Plane felt clean and I was able to get some well needed uninterrupted sleep. I put them slightly above Cathay Pacific as far as cleanliness the only down side was a lack of entertainment selections, but hey I am an American taking a trip on a Japanese airline so I cannot complain. Thank you ANA and the Tokyo airport all very friendly. Will see you soon

ANA gave me an amazing experience. They are very good with customer service.

Everything was good may improve some alcohol drinks and amenities during fly

Very small cramped plane for an international flight. Everything else was good, but it was maybe the smallest comfort-wise I've ever been on for longer than 3-4 hours and the trip was 7.5

Flight was delayed 3 hours. No food and drink vouchers was provided. They offered a mini pretzel bag and water .

Staff was rude. Didn’t give water for 2 hours. Worst service

Was on time until within 1 hour of flight-how does that happen? Staff very friendly.

I liked the choice of lemon ginger tea. I think stewardesses can be more considerate of older people needs.

We were given vouchers we couldn’t use with a 5.5 hour delay

I fly UAL 7-8 times per year. This flight was not up to snuff because it boarded very late "due to unexpected delays in restocking the plane" and yet Flight Aware showed the plane had landed some 10 hours earlier--so I think they could have planned accordingly. The FA's were nice but harried. The video system had to be rebooted 3-4 times. The food service was rather abrupt; they forgot my row and when I asked for my meal, they brought it with some impatience. Overall, the flight was fine, but the little details made it feel somewhat mundane and hurried.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

When I booked it on Kayak it aaid that I wasn't allowed hamd luggage. I called United Airlines and it took them 6 minutes to figure out if I was allowed free hand luggage. Surely something that simple they should be able to tell me instantly.

We were delayed in Toronto on the tarmac for THREE hours with no clear indication as to why except that it was not a safety hazard. Pilot did apologize more than once but even he was unable to explain why exactly we were delayed. I overheard the stewards saying that the captain was very frustrated with the situation as well because he was not able to explain why except it had something to do with water supply or system on the aircraft and now we needed to wait for an engineer to approve the aircraft for flight. It was very frustrating and distressing as a passenger and we should have been given complimentary meals at the very least.

Not to out myself as both a child at heart and kind of a terrible person, but the Pokémon safety video was the first time I watched an airplane safety video in like a decade. It was ADORABLE!! A great way to encourage attention from young and old alike.

Seamless! Long but the seat back entertainment kept us all busy the whole time! Meals were excellent! Crew fantastic! Very attentive!

Our flight was canceled at the last minute. Someone on the flight said the exact same thing happened to her the day before. I will say they helped us book a flight on another airline so that we could still make our vacation with little delay.

The whole experience what excellent, from Anjou at the ticket counter to the attendants on the flight. Although it was an older plane, it was a very good flight. One of the best flights I have had on Air Canada!

The flight was delayed at the last moment quoting an absurd weather reason. This delay led to an issue with my connecting flight. I was made to run (literary) from this flight to the next one ( as they preponed departure. I was still in my DCA to YYZ flight when the boarding started for the next connecting flight. After my sprint to get the connecting flight, found that no place for my carry on. Had to sit for 3 hours with my back-pack on my lap , it was the most uncomfortable and inconvenient journey with little to no empathy shown by cabin crew in both flights. Another poor show from Air Canada!! Cant help because of lack of options !!

Economy middle seat was so narrow that I could not sit back comfortably with passengers on either side of me. Over the 9-hour flight, with my body slightly twisted most of that time, my previously-healthy left knee became very painful, even though I got up to walk multiple times. The knee is still painful 3 weeks later. Otherwise, it was a nice flight, but I was crippled over my entire vacation.

Made me check my carry on despite there being dozens of empty bins when I boarded which significantly inconvenienced me.

Dealing with Air Canada was totally miserable and as a result of their website incompetence, lack of customer support, and total non-responsiveness we could not use this flight. We have made a formal complaint to Air Canada and are waiting to hear back, but if prior experience (more than one hour waits on the telephone with no response) is any guide, we wonder if we will ever hear back at all.

The people are great! The trip to Japan is simply never ending!!! Not the problem of the airlines, though.

We were forced to check in our carryon and were given a green label that said to pick it up when exiting the airplane. We were told by the flight attendant to pick it up at the carrousel instead. We spent more than 40 minutes looking for the carryon which appeared at the wrong carrousel. There was no agent at the united desk for help. There was no entertainment.
