Verified travelerFlew with Asiana Airlines-Mar 2025
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

Pre book a taxi. The lines are insane.

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

Excellent. All well and accommodating. Clean and very good food. Peaceful travel experience

The food wasn't to good but the crews were great, clean plan clean bathrooms always

Aircraft is pretty old. Seat is not comfortable. Meal quality is disappointing. Entertainment system is not impressive at all.

Always on time and flight crew were great. Boarding in Manila was a bit chaotic and disorganized compared to Incheon.

Never had a flight delay issue with Korean Air, that's why I always go with this airline.

Flight crew were very attentive and made this trip a pleasure. Plus the fact that this our first time flying business class.

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

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.

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.

I enjoyed flying on Korean Air. The service was great and the food was yummy, especially the bibimbap and cold spicy noodles. The only thing that bummed me out on this red-eye flight was that my seat did not properly recline so I was not able to sleep.

Seat bottoms were not good, hard to sit so long. Food this time was bad. Crew were absolutely excellent. Plane was good and clean. 30kg checked bag weight limit is very convenient. Price is very good but seems to be rising lately. I'd would like a value plan (check bag and seat selection) but without meal. Is also like better upgrade options, once I purchased my tickets there was no option until boarding gate or after take off, but price of upgrade was still high.

Good budget airline. Disappointed zipair membership program doesn't let you transfer your 30% discount to your family members.

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.

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.

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

Internet connection very poor, means you can not even order items through their own shop.

Een prijsvechter, dus dat moet je ook verwachten. Voor alles moet je betalen. We hebben vooraf een maaltijd en een amenitiesset besteld. Die kregen we netjes uitgereikt aan boord. Het is BYOD voor het amusement tijdens de vlucht en dit werkte uitstekend. Geen trage wifi, helemaal niet. Alles kost geld, zelfs een flesje water. Misschien op langere vluchten wel gratis water, thee, koffie. Maar daarentegen mag je na de security je lege drinkflessen gewoon vullen en mee aan boord nemen
