I flew economy class so of course it’s not as roomy as business and first class. But overall it was ok and the seat had an interesting way to recline — the seat itself extended forward instead of the backrest. This way the person sitting behind me would not lose space by my reclining—excellent concept. I wish all airlines used these seats.

I flew economy class so of course it’s not as roomy as business and first class. But overall it was ok and the seat had an interesting way to recline — the seat itself extended forward instead of the backrest. This way the person sitting behind me would not lose space by my reclining—excellent concept. I wish all airlines used these seats.

Flying with ANA is always a breeze. Seats are very comfortable.

First I will say this was really NOT an ANA flight. ANA used a UNITED jet to perform this flight. I specifically booked with ANA because I did NOT WANT TO FLY UNITED FOR INTERNATIONAL FLIGHTS. So to spend $1800.00 and then discover after booking that it was going to be handled by United was very disappointing. I will be more careful next time when I book. The interior was very cramped in economy class; the dinner meal was terrible and also had extremely small portions for an international flight - the bread roll was ice cold and stale - that salad was very wilted; I’ve never had a “snack” that was so salty that it was difficult to eat; the breakfast “waffle” was practically unrecognizable. Really horrible meals for a very expensive international flight. Bathroom floor was also pretty dirty. I’m hoping my return flight is a real ANA airplane that is cleaned and serviced by ANA personnel with ANA meals. I will never book with ANA again if they continue to use UNITED airline jets. Yuck!!!🤢

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.

It was ok I thought because my flight was 1pm i was expecting to have lunch but it didn’t and after 7 hr finally dinner time was only chicken sandwich and next breakfast was an hour before plane land in Tokyo. so I should bring some food with me. Japanese flight attend was nice but the other was chewing gum and how she ask and respond to customers was not professional I felt. Maybe because Japan flight attendant is highly train and everyone looked very dress and professional so I was kind disappointed. I like that the bathroom was very clean .

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!

They did not get my request for veg food that i made a month ago. Also did not have any backup veg food on board or fruit plate or simething. Very disappointing as i had hward about how grwat ANA was supossed to be. Alsio entertainment was lacking and screen and tech was subpar. Overall just mid to low tie. They are living off reputation and are being passed up by most other carriers.

The ANA Staff were great and the plane was comfortable.

Ana is absolute world class They should not work with united

Good flight. The food was served a bit late, hence a hurry to finish before landing. Excellent crew and service

Excellent meal served with real utensils, cardboard served hot meals instead of plastic utensils and plastic covers. Quick service, friendly and accommodating stewards.

All in all the flight was good. Love the fact that for airline food it was piping hot

I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

Awesome as always. I wish though the cabin for premium was upgraded.... Same old sane old :(

Seating cramped; close to toilet, foul smelling and noisy, very unhygienic and disease risk Free and paid Wi-Fi NOT accessible at all - misleading advertising Very expensive sunglasses disappeared from back seat pouch. Coffee disgusting and cold

Wonderful service, planes and interior in great condition, very pleasant experience

Every thing was fine. Some ild classical Hindi movies should be add

The premium economy seats were not that great. It could have been more premium than economy seats.

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

Hated every minute of it. This flight should have only taken 1.5hrs but was delayed over 10hours. Now I am being told I cannot be compensated or refunded my ticket price or extra leg room, which I purchased but did not receive, because the airline is throwing the blame on the 3rd party I purchased tickets through and 3rd party putting the blame on airline. No one wants to help. They received their money and that's all they care about. Im going on 3 days of still trying to get to my final destination, had to cancel car rental, car insurance and hotel. Currently staying in airport until hotels open up. Thank you Lufthansa, Kayak, Underpricer and United for making this trip the worst ever.

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Awful. I got stuck next to a person carrying a dog and behind someone with a dog. People need to board these dogs downstairs. The cabin is crowded enough with your pets

Packed in like sardines, very uncomfortable. Sitting the aisle my shoulder was rammed into numerous times by rushing flight attendants. Also flight was very cold.

Beverage and food services are excellent. We enjoy paying the extra for economy plus for the 3 inches more leg room to be exact.

Flight was delayed by 3 hours. The pilot made up 1 hour during the flight, but that made the wait at the airport 5 hours once you factor getting there 2 hours early.

Airline did not explain reasons why flight was delayed two hours. Explanations were badly needed and rarely provided. Problem seemed to clearly be the airline’s fault and not the fault of the weather or airport.

Very uncomfortable seats and seat backs, and I am only 5’9”. Delayed due to crew issues, spent a long time with no ventilation. Teeny overhead bins. Wifi worked well. Arrived safely.

I was delighted that we were able to get on the 4:40 pm flight rather than our original booking at 6:55 pm!! Other than that, the flight was comfortable and landed early😊
