I was expecting to fly in a Japanese airline because that what I bought, very disappointed finding out the change of airline without any explanation.

Excellent. There were setbacks, but it had nothing to do with the crew. Mostly, mechanical which delayed our flight.

It was so disappointed trip by unexpected company's fault delay. It had taken 3 hours delay for mechanical maintenance plus another 3 hours for bad weather.

SEA HND sector internet only worked for the last 2.5hrs of flight….. never had this kind of incident with other airlines

12 of the 14 hours were in the dark, all during daylight. Didn’t use my light because it disturbed other people it was illuminating. 14 hours sitting upright in a cramped space was horrible.

I’ve always had pleasant experiences with ANA and that has made me a loyal customer.

UA discouraged people to choose seat on economy class by charging about three times of another airlines. For example, ANA will charge USD60 to choose an aisle seat but UA is charging USD 219.

Roomy airlines. Friendly staff. Timely service. Temp was warm during the flight.

The food was terrible and totally inedible. If you are flying with ANA/United bring your own food it was a long flight to be hingry

I thought I bought the ticket directly through Kayak not a 3rd party

Delta staff was exceptionally helpful and considerate. However, the first two of three flight legs were delayed making connections tentative and stressful.

This wasn't my experience with Delta. It was just the Pegasus flight. Seats were very hard. Staff was kinda rough. Not very nice. Charged me for snacks. For a 4 hour flight I would've expected more.

I had a flight cancel and had it rerouted. When the rerouted they put me at a window seat instead of an isle. It was hard sitting by the window because the couple with masks on were making out. I get motion sickness which is why I need to have the isle seat.

They ended up paying for the bag twice, but the counter wouldn't take my baggage receipt. Left it to me to resolve. Not sure how to resolve the issue.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

Crew was great. Friendly, calm, interesting, happy to be there. That makes a huge difference. Plane was very quiet. Also quite empty so I had three seats to sleep across

I just can’t understand why are you sell to many tickets ???? We had to wait 2 hours before 13 people from our flight take money and go to next day flight!

The only real hiccups in the flight were things beyond Delta’s control - turbulence which delayed food service and a departure delay caused by some VIP plane which stopped all departures and landings for 30 minutes - and was never explained to us by the crew. Otherwise good flight. I would fly Delta again.

The plane was frigid, and leaked water from the ceiling all over me and my seat.

I’ve been on this flight 4 times in the last year for work and the food never changes and always has my stomach upset by the end of the flight. The cold salad with dinner is never a fan favorite with my traveling team.

Flight delayed and then cancelled (due to mechanical issues + weather). Poor communication. No one there to help with rebooking and accommodations for the night we had to stay in Newark. Our luggage was taken off the original flight and apparently left on the tarmac in the rain. Items were soaking rain. The following day, the flight was also delayed due to mechanical issues. The second year in a row that I had to sleep in an airport flying from Tokyo to Newark due to mechanical issues compounded by bad weather. Partly bad luck and partly just poor service.

Polaris seat is plush and conducive to sleep. Cabin crew was experienced, highly attentive and helpful when any need arose, such as finding a lost phone in the seat mechanism. Food was a disappointment, especially the Japanese items coming out of Newark all seemed a bit overcooked, though the empanada snacks served midway were a hit.

I was promised by United Airline (operated by ANA) that I will be seated together with my kids as I am the only adult flying with two minors. We did not get seats together in our 11 hours flight from LA to Tokyo. When asked at the gate, ANA representative said United Airline should have informed them that there is a parent flying with two minors. He said they can’t do anything in the system as the flight is full. He ask me to ask passengers next to me and the kids if they are willing to change seats. This is ridiculous! However, I went in the flight and asked other passages but no one willing to change seats. 11 hours and we were seating separately. I was very disappointed with this. It made things super inconvenient for me.

I paid for a confirmed upgraded aisle seat and was moved to a center seat in the back of the plane at the last minute.

Smooth travel. Immediate update prior flight delay so I can arrange myself properly without too rush.

Even through the flight was delayed due to storms near IAH The flight was great! The crew was so hospitable and professional

United Airlines is my preferred airlines and I am thankful for Gary who also help support me on the phone to switch my flight literally last min.

The flight was on time. I generally don’t drink or eat on short flights and the seats were good and the flight attendants were friendly. That’s all I expect

The attendant were friendly. I suggest you have a medical attendant on board every flight so that in case someone is sick , he/she will help them.

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

I paid extra for a seat up front and at last minute was moved to the 2nd to last row - which I could have had for free. No reason and no refund. Really great customer service American

The first flight was delayed by an hour and a half, so we missed the second flight. They rebooked us on the later flight and I have to sit in the middle for more than 5 hours. Terrible experience. No more American Airlines.

Flight was fine, but not having WiFi was a major negative

I was trying to take 2 one and a half hour one way trips and I experienced almost 20 delays over the course of those two trips. Only a few of them were due to weather the rest was disorganization

Would have thought that they would gas up plane before everyone got on board

The flights were terribly delayed and then cancelled which forced us booking another night at the hotel. Very poor management from American Airlines

American switched my flight to a 5 hour layover then cancelled my whole reservation with no notice and refused refund. Won’t fly with them again.

We sat on runway for an 1 hour because they were short handed at key west airport was not fun

The WiFi and app don’t work as easily as other airlines

Late. Then next flight was an hour late due to mx.

Flight attendants had an attitude with everyone, not sure they should be working with customer service if they cannot show a pleasant attitude. Underwhelming, to say the least. The food was awful, and nothing could be purchased from Toronto to Tokyo. Do better, Air Canada.

Thai Airways was exceptional in all ways. Business class was very comfortable. Service by the staff was very genuine and caring. Every need address quickly.

From Tokyo to Toronto, the entertainment system in my seat was malfunction. I could not watch any movies nor knowing the map of the trip.

The meal options were ok but the actual food was terrible. On my return journey, they simply said that there was no vegetarian option and somehow struggled to give me dinner and did not give me any breakfast at all which in my opinion was terrible. Not having ANY vegetarian meal was surprising and never had such an experience in the recent years.

Didnt make it on flight. Flight was delayed. Then had to get rebooked for a flight that was 8 hours later. Guess who had to wait for 8 hours at the airport?

The Air Canada AC1 flight from Toronto to Tokyo on May 16 was great overall. Service, crew, food and entertainment were all excellent and everything ran smoothly. We had emergency exit seats so legroom was amazing, but the seats themselves weren’t very comfortable and the plane feels like it could use an upgrade for a long-haul flight. Aside from that, everything else was perfect.

The plane was very cramped to point there was no way not to touch person beside you and a stewardess screamed at my son when I touched her arm to get her attention to let her know she forgot to give him his dinner when she passed him and gave a dinner to passenger behind him. Very inappropriate response and She never came back to apologize and other stewardess said she was sorry “if I felt” she was inappropriate. Horrible experience and she should be reprimanded for her behavior

Everything went smoothly — on-time departure and very organized boarding. We pre-ordered vegan meals, which were fine but not especially memorable. We may have had slightly higher expectations given it was a Japanese airline. It felt like a dinner meal than a breakfast. Overall, it was a good flight experience and we would recommend it.

This flight with a lot empty place , and I have more room, feeling comfortable.

My flight was overbooked and they would not let me board. I had to book another flight and pay the full amount of that flight. I did not get any help at all from Air Canada or United Airlines.
