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

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

Korean are so racist and when I ask question or directions they totally ignore me and say racist. Also they give me an rude attitude.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I normally love Korean Air, but this trip was not great. We boarded the plan and were settling into our seats. My son and I use these leg swings and we used it on the trip over to Cambodia, but on the way back the flight attendant very rudely told us we could not use it and that it was against regulations. I asked to see the regulation, but never saw it. The food on this trip was horrible as well, Even my son's kids meal was disgusting so we didn't eat anything on the flight. Thankfully we brought snacks. Entertainment - what happened to the games?

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

I’d have rated Asiana good except an unfortunate incident in which I felt one of your employee didn’t really help us. During the first leg of the trip, the flight from LAX to ICN, I left my backpack on the plane. When I realized, I reported to one of your employee who promised me that it’d be taken care of, that my backpack will be there at HCM city. When we arrived there, HCM people had no idea and my backpack was still at Incheon airport who denied any knowledge whatsoever. I was left in the cold and felt helpless. I was very disappointed. I’d like someone to look into this and let me know.

It was my first time flying Asiana but i was very pleased with how professional and understanding the flight crew is with little kids. One flight attendant held my 3 year old daughter’s hand guiding her to the exit after landing while i had my hands full with luggage and my infant. She was very helpful.

The customer service was excellent. They noticed that our connecting flight was scheduled too closely for us to complete customs, so they changed the flight. Our initial flight was delayed, and they were able to get us on another flight, all without charging us any additional fees. I would fly them again anytime!

2nd major delay due to maintenance issues. 1st delay missed my connecting flight.

It was great, but my bag was not loaded onto the connecting flight. I'm currently getting it resolved. If this isn't a problem, everything else was excellent.

The aircraft was massive (A-380) and became crowded with 400+ passengers on board.

The plane hasnt left im stuck in seatle still my flight has been grounded for almost 5 hours

My luggage didn’t arrive with my flight. Flight was delayed by nearly 2 hours while we sat on the plane and I almost missed my connecting flight and subsequently missed the last train from the airport so it took me another 2 hours to get to my destination after arriving, Crew skipped me several times when offering beverages, and I couldn’t get their attention at times because they wouldn’t even make eye contact with me. They didn’t give me a form for disembarking so I had to go to the back of the line after waiting an eternity for immigration. Paid for on flight wi- fi that didn’t work for most of the flight.

Love flying Asiana. Been using it for over a decade now.

I had a bad experience coming from America to Thailand. On my connecting flight my check in suitcase was not put on the departing aircraft, I received my suitcase 24 hours after arriving in Bangkok and when I open my luggage my hand swelled up. The next morning when I put on an outfit from my suitcase my face swelled up and became numb. My entire vacation was ruined it seems that some kind of chemical was sprayed into suitcase and ruined my clothes and got me sick. The staff at my hotel called the airline and spoke to someone and they told me to file a complaint and gave my a website to do so. I did not file a complaint I felt like it would have fell on death ears. I had to throw away my brand new vacation clothes and suitcase and I had the worst vacation ever due to this happening to me.

My seat 3G did not go down fully and the buttons were not working properly

Food has been disappointing in both legs of flight to india

Great staff great experience, made a 2 hour delay very bearable

Great staff, great experience, made a 2 hour delay very bearable

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Great crew - old style upper class seats on the older fleet now feels dated

On time. Friendly and helpful flight attendants. The plane was clean. Having a wine available would have been nice.

Your staff was exceptional. Could teach the other airlines-rules on etiquette, and service. Excellent landings on flights, carried out by your pilots. Only complaint is long delay on return flight in Beijing, onto Vancouver.

Worst than I expected, crew was not attentive, meal was as disgusting , they didn’t even drink selections as they would to other passengers. I felt discriminated

cannot get seat information for LAX to IAH when check in in XI,AN

UA is ok. But check in was a very bad experience

I hate that you cannot check in online and when you are at the airport, there aren't any aisle seats left. Also, they could work a little on subtitles for their movies (not everyone is a native English speaker).

Nothing to complain of, the only reason I am not giving better marks is that I am used to flying with ANA and they are the top.

It's terrible that we can't do online check in because we didn't buy the tickets directly from Air china. It was not explained until I contacted Chatdeal and we could not sit together.

Communication between the captain/crew and the passengers needs to be improved.

Food and service are good. Bathroom was lack of lotions and cleaning. That should be improved.

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

Ground staff and cabin crew were excellent. Flight was perfectly on time. Zero issues.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

Efficiency of staff, and comfort and cleanliness of aircraft was all great. Maybe a hot drink without payment at that time in the morning would be good!

Flight was late arriving. So, we left 25 min late. Pilot made some time up during the flight. Therefore, we arrived alittle past original time.

The plane was late (as was my flight out from Birmingham the day before)

Very good experience. All of the details made this experience very positive.

Never happened. Flight was delayed. Had to be re rojyed

Very small and uncomfortable seats, Hard to hear entertainment system sound. Horrible food. Staff doesn't care much about the passengers. 2nd time they didn't give me my vegetarian meal. They asked me regular food with meat. The airline and staff was from United airlines.

Small plane, only two bathrooms, no screen for videos. Not wide enough seats
