Yes, really loved Korean: they also have great airports. I have also flown in Russia. You are very right. 

All my years of business flying has shown me the following: European airlines are good and in the middle to upper of the pack; in North America, Canadian airlines are the best, but not globally: globally they are the middle. Things get crazy once you start flying in the former Soviet Union and also in Africa. By far the best I have experienced have been Asian for food, flight attendents and overall service.
