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

This was an amazing flight. The crew was great. The service was great. The food provided was great.

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

Korean air has a little bit more seating space than Asiana air.

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Unfortunately, there has been a boarding and departure delay. However, as usual, the flight arrived earlier than the scheduled. There has been a turbulence in-between, it’s unavoidable. I couldn’t complain them.

Not many people, so you can lay down on two seats

The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.

The food on this flight from NRT to ICN was average. The staff were very friendly, but the flight took about 60 minutes longer than it should have because the pilot was only flying at 330mph instead of 500-550. Not sure what the reason is for that, but it meant for a much longer flight.

Flight delayed going to Korea. No free WiFi. Other than that everything else is were good. I would love to fly with Korea airline again

Wonderful I would recommend it to fly & ride with ANA.

Flight delayed by one day and everything was so disorganized by the airline.

All the food seemed to have onions. I don't eat onions. Anyway, everything else was great. The biggest downside was the underpricer company that purchased the tickets from ANA. Underpricer never provided the United Airlines booking number. ANA was a code share and all our flights were on United. I finally was able get booking numbers from Ujuted on X. They saved me from the upsales underwriter tried to saddle my wife and me with.

Due to turbulence there was no inflight service, which is very understandable, The flight is very short, and safety is more important. There was a bit of a delay with take off, but was to be expected with the rain.

Overall the experience was ok. My two complaints are that the food is absolutely disgusting. The movies in the flight to Japan were a completely different selection than the ones on the way back. So if you’re looking forward to watching a certain move on the way back, think again.

Hard to explain because we thought we were booking ANA airlines, not ANA operated via United, so we were disappointed, but for what it’s worth, everything went smooth and loved the movie selections. The food was okay, processed and full of preservatives, so vs what we were expecting with ANA it was different

My wife and I liked everything except the cold breakfast

My wife and I liked almost everything about ANA except for the economy seat space and the cold breakfast (croissant which seemed to just come out of the fridge)

The overall experience was ok, though there was certainly room for improvement. My husband was asked to check his carry-on bag at the gate due to claims that the flight was “full.” However, upon boarding, we observed ample overhead space and several empty rows of seats. This made the request appear unnecessary and caused some discomfort, particularly as he was the only passenger singled out for this procedure.

Excellent service and comfortable seats. Friendly and helpful staff. No food for a 3hr flight over lunch time which was surprising (or is that a feature of domestic flights in Japan?)

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.

Nice service. I wish it could provide hot water on the flight.

internet didn't work. No offer of drinks or snacks.

Flight was seamless. Free wifi helped pass the time. Food was okay, just make sure you pre order or pick something up from the airport

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.

I didn’t even fly on it can I get my refund
