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

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

Awful. They cancelled my flight from Osaka to Tokyo and did not communicate this with United so my flight was never rescheduled. I had to call United myself who, after being on hold with them for an entire hour, did not believe that my flight had been canceled because ANA never reported this. ANA themselves refused to rebook my flight. United then said they would only rebook my flight for $600. After three hours of calling I was able to rebook my flight. My total trip was delayed 7 hours.

Flights got canceled due to weather and rebooked; however, were rebooked for the latest times and I was unable to move anything up.

Overall great. For improvement: early online check-in with seat choice.

The food was really good and healthy. Hopefully, next time final confirmation before the flight is earlier with complete information such as the Seat and Terminal Numbers.

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.

Jain veg meal I opted was super in taste but there was no sweet/desserts with it. I was a big missing in the meal...Please add some sweets to end the meal with 😊

The meat-and-rice combination was a good idea, but the food could use some improvement. The meat looked a bit mushy and almost like ground meat, which wasn’t very appetizing, and the flavor was just average. Other than that, everything else was great.

Weather delayed arriving flight and even though I made the connection, my luggage did not.

Great! Internet is below its competition. Poor connectivity quality and speed.

It is too long a flight to not have free access to internet. Should not charge. Should be some hours free.

My boarding experience was so bad. While traveling from LA to HYD, the boarding was smooth. But the boarding experience from Hyderabad to LA was utterly poor and unprofessional and caused lot of anxiety and stress. Even though we were at the airport Boarding well in advance to accommodate for Immigration and Security Check, Cathay Pacific Boarding On Ground Crew has done a very unprofessional job. It is one thing to follow rules, but being inconsistent and not being able to communicate this clearly is wrong. I was not aware that my laptops weight in my backpacks is also counted against the cabin baggage. While coming from LA to HYD, the ground boarding crew didnt ask for this. They just checked the Cabin bags weight. But at HYD, not for everyone, but for some people they enforced this. Our Checkin Luggage was carefully weighed at home and was accurately measured to 23 kg, Now they asked to move all the weight in our Backpacks where most of the weight is from Laptops and tablets for each family member, I need to accommodate this ~10kg from 6 laptops in to one of the suit cases and pay extra for excess baggage at the airport boarding place. Without a weighing scale how can I accurately move all the items from cabin baggage to one of the suitcase. D Venkatesh is the guy who enforced this. But I dont have a problem with the rule enforcement, but the way he guided us in solving the problem. I was willing to pay the extra money for the extra weight. He told me that the 32 kg excess baggage is allowed with 150 USD. I understood that 32 kg is extra on top of the 23 kg chickin baggage. SO I pushed all of them to one suit case and then when I took this suitcase, I was sent back saying that he meant the total as 32kg but not the excess should be 32 kg, I had to go out of the line make these changes without a scale thrice like this. They literally harassed me. Noushad his manager was sneering at us. When I said, I am going to complain about this, my wife heard him saying some bad words in Hindi. You get one chance to harass your customer. I will never board Cathay Pacific again.

I’ve flown 2 better Asian airlines in the past year.

Good experience and I would fly again with CP. Disappointed that they ran out of the dinner option that I preferred. Other than that, the trip was quite enjoyable.

Great entertainment system, the seat is a bit old style needs refurbishment

Boarding at the airport was not well managed. Otherwise, had a good flight sitting in the first row (which I paid for). Crew was pretty friendly, and flight was smooth.

Between being the only jetstar flight delayed to changing gates at the last moment and starting boarding late, jetstar dropped the ball on this one. we had to run for last train. Never again

The seats are very uncomfortable just was not a pleasant experience

my flight was cancelled an hour before departure and i have not received a refund yet.

A child behind me was kicking my seat and the cabin attendant noticed and kindly asked me if I’d like to switch to a different available seat. Really nice.

The flight crew was very nice. Had a bit of a hiccup on my end when I checked in flying from Tokyo to Sapporo but the staff was very helpful. Definitely enjoyed both flights.

Captain smooth landing, Crew efficient and helpful. We saw Mt Fuji from the plane. Thanks.

On time and smooth flight from San Juan direct to Sint Maarten.

Just to be expected on a budget airline. Since all the flights were either late on the evening it would help to offer some food for purchase Since you tourists cannot buy decent food withoit local vaccination record in hong Kong this would really to help Using phone to submit electronic data is great but for the elderly this is a hassle

Flight cancelled without notidication, had to book an emergency replacement flight at the counter

Thanks to the kind staff for locating my lost onamori.

Quite ordinary, as might be expected of a budget flight. It was difficult to understand the instructions unless one speaks Japanese, and the seats were quite basic.

Very easy process overall. The staff communicated well and everything was efficient.

Very affordable, smooth check in process, flight attendants were safe and kind, lots of flight availability within Japan.

The seat is so bad Can’t recline the chair

For Travelers with babies, if they can be supported by allowing to carry the Baby stroller upto the Airplane gate, and not submit at the Check-In counter. it will be very convenient. Thankyou.
