The only reason I gave comfort a good and not an excellent is over something Korean Air has no control. I choose an aisle seat so I can easily stand and walk to the lavatory and so I have only one seat mate to contend with. In my case, I had someone who chose to horn in on my space. At its worst, she laid her head on her companion’s lap with her feet close to me. She made sure her feet were covered with her blanket and scrunched up so she wasn’t exactly in my face. That was good enough for me not to complain to the fight attendants.
