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.
TanyaFlew with Asiana Airlines-Jul 2024
Maybe don’t sit in the center aisles for such a long flight. No way to lay your head to the side when sleeping
MichaelFlew with Asiana Airlines-Jun 2024
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.

Tightest knee space ever experienced on any budget airline. Crew polite and efficient, take off and arrival on time. Surprised that they did not offer water on flight except as sales product. Questions about Food and entertainment not applicable since neither are offered.

At the boarding gate, Jeju airline accepted "carry on" bags for checking in for free due to the "limited cabin space". This is because most passengers were carrying multiple bags that exceed the size and weight limit for carry on items. Rather than inspecting carry-on bags at the counter and requiring excess bags to be checked in for a fee, they allowed freeloading at the boarding gate to to the detriment of those who paid the fee for checked bags. This is totally unfair.

As posred earlier the crew was very accommodating & professional. Thank You Allen

All though you can not help it the kids was loud and unruly, The crew was very accommodating and professional. Thank You Allen.

No priority counter check in for families with young children.

The flight was delayed from GUM to ICN, there was no notification on how delayed the flight would be. Although we received notice, there was no specified time given. The flight was also very uncomfortable.

It was a good experience - too many times checking at the airport - every time had to remove shoes , belt , laptop etc. that was a bit of exaggerated. The seat had a sharp metal plate -- which torn into my jeans.

The crew was not helping us in the airports ..Very bad experience..the washrooms are not meeting the expectations..need more good service... The hotel service was good but there is a very long wait time which wasted time to go through..

I had a comfortable seat that makes my trip wonderful. I appreciate the Ethiopia crew, they were very helpful

Needs improvement because some of the tvs and charging ports weren’t working

Like: It arrived, Dislike: Boarding was a separate corridor with no counter announcements at the passenger waiting area. Very dirty airplane and toilets, food options were terrible - everything even the vegetarian option was a curry spice. Many other passengers using the toilets would not lock the door and kept door partially open during use - flight attendants would not enforce or direct them to lock it and light turns on, no entertainment options at all, other passengers would be singing and not peaceful. Atrocious flight experience.

I have been flew with ET since 2013 and I wish the service can be reach standard airlines as Star Alliance member please ET you need to improve many thing on the services learn from SQ and other member

Lost our bags. They didn’t make it to Lilongwe

I still cannot find my luggage. I need my luggage.

The food could be better, the beef was quite tough. The crew were friendly and helpful on this flight, which has not being my experience on other Ethiopian flights.

Flight was smooth but unnecessary long because we had to refuel at FCO Rome. Air hostesses service and response to call light could be better. Both planes were old with broken seat arms and toilets. Why Africans had to be given the farthest Gates is what baffles me and why we have to pay for Aisle seats I found really strange. Is there ever an end to ripping people off even after paying over $2300 for one seat.
