Crew and flight were professional and courteous.

Passengers from Beijing were rude, and consistently snorting and spitting throughout the entire flight. Not just one person but everyone around us. Very disgusting and nauseating listening to that for 6+hours. I had earbuds in the entire flight and could still hear the spitting...

Boarding process was really quick. In half an hour they boarded a complete flight.

There was a very rude person sitting behind me. He kept hitting my seat every time I reclined it. I brought up to the flight attendant but she had no intention of getting involved or helping out.

Boarding time was supposed to be 19:10, we did not start to board until passed 20:00. Needless to say we were delayed. There was a woman at the counter,but there was no explanation given about the delay. Luckily it was the last leg of my journey and did not miss a connection flight,but being on an 11 hours flight just before, I was a little cranky. Overall I had a great experience.

they should really do something about tight connections. If your first airline is only barely late, it becomes a frantic haste from hell to get thru security again and to your next airline. Security needs to inspect every element of your carryon in spite of the fact you were already screened on your previous flight. They will dump out your entire bag to inspect all contents. Extremely easy to lose important things. They confiscate all spare batteries if they only appear to be high power range regardless of what the actual voltage is.

Same exception experience with the flight attendants, boarding was smooth, food is good and along with entertainment selection.

The plane aisle is a bit tight and cramp and it is hard to move around. The chair in economy is not very comfortable very sturdy lack of cushion and back support. Leg room is ok, not as roomy as the flight from SFO to South Korea. When we boarded there was a strong smell burning fumes from the A.C. (air condition) that trigger my asthma and landed in Cebu very ill with asthma and allergy.

I like the Korean Bibimpap on the plane, taste was good.

Old style business seating, quite uncomfortable, not a full recline, very uncomfortable when fully reclined compared to other business planes, TV was small, not good quality, selection of movies was only ok, not great, service was ok, not great, they cater more to Korean customers then other guests, if you are on the upper deck de-planning is difficult and awkward as you have to go through the economy section and staff doesn't keep them seated, so no extra bonus for business in de-planing. washroom items not replaced (toothbrush / mouthwash), overall very average

I bought a ticket for three persons: my wife, my daughtet and me. I am Nigerian, my daughter American, and my wife's Turkish. However, because of the diplomatic row between Turkey and the U.S., my daughter was refused entry into Turkey. Turkish airlines' policy was to refund the ticket of any American caught in this row. They said they will refund my one month old daughter's ticket. However, my wife and i will not receive a refund. We bought the three tickets together. Our ticket numbers ended in 235...51, 235...52, and 235...53. However, they will not refund our whole money by cancelling the ticket but only that of my daughter. So this is the question: Does Turkish airline want me to leave my one-month old baby in the U.S. and tavel with my wife to Turkey? What kind of parents will we be if we were to abandon our daughter to take a trip to Turkey. Even, the people in Turkish airlines will judge us evil parents, yet that was exactly the only option they gave us. Lose your daughter or lose your ticket money. They will not even just change our iternary or give us another destination we suggested without penalties which are almost 3/4 of our initial ticket price. They just made away with our money. You cannot say, 'We are cancelling tickets for American citizens' but make no exception for parents of infant citizens. This is the height of criminality. So, me and my family couldn't take the flight and lost $1500. We had to buy another ticket by airfloat to get to Georgia. But Turkish airlines refused to even contact us on the refund for my daughter. A truly criminal enterprise.

They had a vague refund policy for Americans, forgetting that American infants can also have none-American parents who are as much victims in this as the American infant. For them to be myopic and keep repeating talking points of their refund policy is unfortunate to say the least.

My first time to fly with Korean Air and I would not hesitate to fly with Korean Air again. The plane has a lot of leg room, aisle is not cramp to move around. It was a long flight, but the flight attendants made it worthwhile. They were very attentive to your needs with exceptional service. The food selection was good. Overall the best flight I've ever had flying overseas.

Maybe the chair in economy can be a lot more comfortable. Chair is sturdy lack of cushion and back support. People like me who has mobility limitation and bad lower back is difficult coz it adds more discomfort on my end. Hopefully, one day the chair can be more comfortable.
