Though the flights to and from Tokyo were the longest (and some foods I found a little bit unappetising, but some I liked), and Osaka to Tokyo was very short (therefore no food or entertainment), I kinda enjoyed them and might use them again if I go to Japan again at some point in the future

Very nice staff and very good choices for food and drinks.

The flight took off at 10pm in Singapore (which is not an issue). However, the breakfast was served at 2:00am Singapore time to ETA of 5am SG time. Hence, it was difficult to get much of rest or sleep during the flight.

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.

The stewardesses were excellent! The food and service were great. I will definitely fly ANA in the future.

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.

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.
