Airline reviews

Ticket was purchased as a United Airlines flight (operated by All Nippon) like what does that even mean? Makes for a VERY confusing flight experience. For instance, what do I look for a United drop off signage and ticket counter or ANA? No explanation anywhere to be found. I also felt a little bit scammed by the obsurdely restrictive seat selection provided. Only middle seats available!! Are you kidding me!! On 6hr + 10hr flights you're forcing me into the middle seat without telling me before I purchased the ticket?? This should be illegal. And to top it off, on the Tokyo LA leg there were quite a few empty seats including window seats! I must also say, the food was a dissappointing as well for my taste, fish with rice ( mostly plain white rice) or a vegetable medly for the breakfast meal? Should be at least 4 choices and at least 1 with eggs. Outside of these issues flight was otherwise ok.

Ground and flight crew were all courteous, extremely helpful and professional. Overall, process is really organized, from boarding to disembarkation.

This is a very long flight and the first time I have flown on a Japanese airline. I was very impressed with the staff. They worked hard and offered food and drink regularly. Plane was very well cared for. The let room was good . Food was ok but better than other airlines.

It was very nice. I was a bit disappointed by the few meal services. There were probably more drink services that I missed while sleeping, but I would have liked the crew to bring more than one drink service before landing and to bring more than one drink service and coffee service after take off

The space and bed was very comfortable , flight attendants very nice. The food was not tasty at all. I ordered the rib eye and it was so tough I couldn’t cut it.

I wish the serve should leach and drink. Maybe because only 2hr

Seat was roomy enough . The Asian selection for a meal was good . The tortellini was not very good. Service was excellent. O

It was very good. Lots of room with superior food and service. I will not hesitate to fly ANA in the future!

I love everything about this airline but it could be better if the waiting time for boarding is on time.

Japan and China airlines were incredible. On board service was impeccable. All the flight attendants were helpful, friendly, and always smiling. Airplanes were very clean. The boarding crew was extremely accommodating and very nice as well. Overall I was extremely impressed.

Liked the food. Needs improvement: 1) the flat bed was very hard and the set up was not at all passenger friendly 2) the announcement were impossible to understand even in English. 3) the flight information on the monitor was terrible it showed a airplane with no information like altitude, airspeed, heading. You could not zoom in or out to orient the aircraft to where you were in the flight. 4) movies were old and very limited as was the music selection.

This flight was operated by American Airlines. AA was completely unprepared for the crowds at DFW for Spring Break and were ridiculously understaffed. They had only three operating kiosks for self check-in, and ONE agent to handle hundreds (thousands?) of dropped off bags. She also had to do double duty to assist passengers at the kiosks. In comparison, flying on United Airlines at Christmastime was a much smoother experience.

Need new movies, a lots of them are 20-10 years old or older. It us a very long flight we need good entertainment. Please load more new movies!

Good and movies are so old. Needs to have more up-to-date movies.

It was an outstanding flight and service. The only thing is the seat cushion for economy could be a little more comfortable. More cushion.

Although delayed leaving the crew were lovely, comfort of the seats was excellent. Cabin was a little too warm but overall the best economy flight we have taken

Comfortable flight since I had the entire row to myself. Food was good too.

Movie dis not play smoothly. During play, it was interrupted several times, and could not RESUME where I was.

JAL has an excellent flight staff, even in economy we had a great flight

Consider adding “N/A” to some review options. This flight had no food or entertainment.

While I was in great pain, the seat was sufficiently comfortable to allow me to rest and not be in so much pain.

we were upgraded which was a blessing and tender mercy for us. I fell the day before and was in extreme pain from knee to shoulder. Sitting in a more comfortable seat during the flight was an unexpected blessing and experience.

Not impressed with check in desk staff at Vancouver airport. Not a professional mind service and not cared or tried to help. Don’t think I would fly with them again

Seats were very comfortable. Crew were excellent. Food very good.

Flight crew was especially thoughtful and attentive, made sure our seats were comfortable so we could rest on the long flight

Everything went smooth. All flights were on time No changing gates, . No changing flights . It was like a completely different airlines tha n the last time I used Cathay Pacific . The last flight, 2 months ago, I had before this one was from Philippines also . I got changed in Manila and was told it only added 2 hours onto my flight . My 20 hour return trip ended up being 30 hours return with a 10.0 hour layover in New York with no seats anywhere . Everyone was sleeping or sitting on the floor . Unlike the hotel I was given in Manila to wait for this flight home . I never thought I would use Cathay Pacific again . But I did and this time you were great! I should have complained about the flight and layover from Hell a couple months ago. Consider that I am complaining about that august/23 flight now . Thank you got the great flying experience on my way home from philippines .

Everything was good food could be better but ok for economy on my 2nd flight the head ph jack are bad you have to hold pushed in to hear anything but other then that very nice service

In flight entertainment system including wifi were down and passengers got tortured for the 16 hours flight without any of these. Food was spoiled as well for the first meal provided but second meal was Ok. Overall a horrible experience which was not at all expected for such a long haul flight which was expected to be THE most memorable part of my planned trip for family.

I traveled to Singapore for 5 days, I didn’t receive my luggage until the 3rd day. When I received my luggage was broken which they fixed it supposedly. I never had such a poor experience with the any other airline. I honestly think it should be a compensation for all of my losses and suffering that I went through.

I booked this through Travelgenio and requested a cancellation due to COVID related impact. Their customer service was absolutely terrible and they informed me after the flight had departed that they could not cancel my ticket. Worst experience, will never use them again. Strongly reconsidering using Kayak in future given how poor the travelgenio experience has been.

Great seats assigned and comfortable, movies are good, food is delicious, great experience. No delays and they prioritize boarding children with parents which is plus.

they canceled my flight and we’re absolutely atrocious and helping me rebook

My flight was canceled. New flight is 40 hours later and I still didn’t get the flight from Frankfurt to Zagreb.

Great service. The flight was in great condition and the staff was very cheerful.

Check in crew in Charlotte NC was superb. There were 6 of them plus what looked like a supervisor, helping to answer questions and keep things moving. Never saw so many check in crew. Then some of them showed up at the gate later for boarding. Great. The flight was mediocre. The seats were small with little leg room. The screens kept coming on when we were trying to sleep and wouldn’t shut off. I know we paid far less than first class but does that mean we should be shoved in there??

Boarding was horrible. We were packed into a bus with few seats and made to stand for 10 to 15 minutes, then driven for 5 minutes on wild curves. Complementary food and drink was a tiny chocolate and a bottle of water. Seating was cramped. Aircraft had no video.

didn’t even get to go one of my returning flights cancelled and I wasn’t even in their system, vacation ruined thanks for nothing

The process overall was pretty seamless, and the crew were very friendly (especially Michael). Considering we booked expecting Lufthansa and the flight was operated by United, it was still a very good service and journey overall. The in-flight entertainment was great, with lots of quality options. One slight negative was that I had selected a vegetarian meal prior to flying, but received a vegan one. I think there should be more dietary options as it meant I missed out on some food that I would have preferred (and it seemed like the standard meals and snacks had a vegetarian option anyway). There was also a group of people who were moving around a lot and being generally disruptive at the quietest part of the flight, when the lights were off and most people were sleeping. I would have appreciated staff stepping in to encourage them to be mindful of others). Towards the end of the flight (which was very early in the morning in both time zones), the lights suddenly came on and breakfast was served. In my opinion, this was too early, and everyone was rudely awoken from sleep. After breakfast was cleared away, the lights went off again for about 45 minutes, allowing people to sleep some more. Then the lights came on again for landing. It seems like if they had served breakfast later, the lights on-lights off-lights on shenanigans could have been avoided, and people could have slept longer (and staff could have rested longer too).

Crew was rowdy and loud just hanging out in the rear of the plane instead of assisting passengers during boarding. During the flight the crew mostly hung out in the rear of the plane being obnoxious to a point of disturbance.

The accommodations are top-notch. The only negative was that both our initial flights were delayed, which caused us to miss one and almost miss the other. The staff immediately handled the missed flight and compensated us for the inconvenience.

Flight delayed two and a half hours from Toronto to Calgary Philadelphia to Toronto we were listed as standbys !!! Very concerning

Flight delayed at the last moment Hill next day and havé to drag at Hotel at our cost and bec day was again delayed 4 Times because no crée and no pilot

The flight was more compact. The flight was more turbulent than usual. Otherwise no complaints.

No food, not even snacks on the 6hr flight from Newark to Vancouver! The movie collection made up for it though and they did come around with drinks twice. Just good to know so you can eat ahead/bring snacks onto the flight. It was a bumpy ride induced by wind and rain but otherwise got to the destination safely and promptly.

On the flight back from SFO to Vancouver ..the crew was less than professional. They completely missed asking if I wanted a drink (and I was awake at all times) and I had to walk to the back of the plane to ask for a cup of water to take with my medication. Also, there was a charge for ear adapters for the movie screen which were given out free on the flight from Vancouver to SFO. The flight from Vancouver to SFO had pleasant crew members. What a difference in the flight back.

Announcements were to loud, too insistent and too often. The same messages can be made in a nice relaxed, yet efficient manner. There is no need to "talk down" as if on a mild power trip. It's immature and unnecessary. This is a constant irritant especially with Air Canada. Learn from your European competitors to have a bit of class.

New Airbus 220 with all the amenities. Not sure why hot beverages were not served as flight turned out to be very smooth…

My flight was cancelled. The flight they booked me on was delayed over 2 hours with mechanical problems so I missed my connection and they ran out of hotel rooms, so I had to book and pay for it on my own. I also had to pay for food out of pocket. It was a terrible experience.

Flight delayed by 3 hours because of lack of available plane. So why were we notified on the morning of our departure? Is your scheduling that bad? We, in zone 4, were told to check in our 2 carry-ons because of lack of storage space in the plane. When we boarded the luggage spaces directly above us were empty and so were others. In fact there were many empty seats. If each passenger is allowed one carry-on why is that right revoked at the last minute at air Canada's whim? The AC app doesn't work. It refused to show our boarding passes, and track our luggage. In fact it indicated that the flight was on time even though it was delayed by over 3 1/2 hours

The cabin crew were really good!! Check in etc. was very good. We enjoyed the aisle seats as the plane was small! Couldn’t comment on the food as we didn’t order anything!
