I really enjoyed my flight. The crew was friendly and accommodating without seeming fake about it. The food was good and in a sufficient quantity. My biggest highlight is the leg room. I am only 64 inches tall and I have been on other flight where my knees touch the seat in front of me. On this flight, I had plenty of room even when the seat in front of me was reclined. This makes me feel that Korean Air cares about the comfort and health of their economy class passengers and not just their bottom line. I did not feel like I was getting an embolism in my legs as I have on other airlines. The seats were comfortable, the blankets were clean and smelled fresh, there was a water bottle at my seat upon boarding, there was a package with a toothbrush and toothpaste, and the bathrooms were serviced and cleaned regularly. I watched 3 recently released movies and played games as part of the in-flight entertainment. My only minor complaint would be that my meal tray had coffee stains from the previous traveler. Although everything else appeared to have been thoroughly cleaned such as (thing I notice that others may not) my seat belt buckle, the button for reclining, and my touch screen and remote control, I think the cleaning crew may have forgotten to unfold the tray. I will let that slide since everything else was top notch. Plus I always bring disinfecting wipes with me when I fly because I have seen unpleasant behavior from other passengers in the past so I always wipe everything down anyway. Overall, I was very satisfied with the flight and I would certainly choose this airline again.
