The Aseana Air ground crew & in-flight staff were very professional & efficient yet pleasantly helpful & accommodating. Although it is no Changi airport, Narita has so many shops & restaurants to help kill lay over time .Bring power banks as the charging ports are far few & constantly clogged.

Maybe don’t sit in the center aisles for such a long flight. No way to lay your head to the side when sleeping

I like the landing which is nice and safe, seats are also comfortable

Staff on board were good - food was fine tasted good - tv was old 1970ts in seat back but hey it was a 2 out flight so no drama

Punctuality is a great factor. Boarding, departing and landing in timely fashion. No hazles and very profesional service in land and during the flight. Great experience.

Wifi never really worked. Flight attendants were generally fine except when they were not very helpful when my wife accidentally spilled a soda (they chastised her to apologize to the people sitting behind when it was dark and we couldn't see anything and they brought one tiny napkin to help clean it up). Seats were uncomfortable for all four of us. Otherwise a typical flight.

Seats in economy might too narrow. people sitting next to each other is always hitting shoulders.

Easy to board and fly, no frills. Yummy ramen on board.

It was for the most part a 10/10 they said they had entertainment options but all they had was old movies for streaming from the mid 2010’s so like 10 years ago

all good for a very budget flight - well priced and excellent service. Will fly again

Couple of the crew members were really nice and the rest are really rude and didn't help when we needed help, food was not worth it at all and most importantly there's no even entertainment system other than a very interruptive and slow internet and some movies.

I appreciate the economy price of the tickets. The long flight made the comfort level on the lower average side. Wi-Fi connection was not consistent but working. Overall, I would fly again with zip air but next time get the flat, premium seats with the amount of money I would save otherwise.

Comfortable seats and lucky no one was in middle seat. No water on the plane. Plane was on time and staff was fast.

You get what you pay for and nothing more. Wanted a cheap flight and that’s exactly what I got, though it’s human nature to wanting to feel like you got a good deal as well. There was none of that here. I was cheap and they were too. Got to my destination safely and that’s all that really matters.
