KE is a world class airline that has mainly Korean customer base.
That is why KE is still very exotic to many foreigners.
The Koreans are STILL willing to pay a bit more for KE's good inflight services,
at the same time without knowing how bad it's frequent programme is.
As a flyer who have flown over 40 airlines in the past 25 years, I can think of only few airlines which offer better inflight service in Y than KE.
KE HAD a bad safety record, but it has been many years since the last accident occurred. Just like you do not call Germany a Nazi country after some 60 years. KE now deserves better image and verdict.

The same is true of Aeroflot, I would like to add my personal opinion.
I have flown SVO-FRA, SVO-AMS, SVO-HKG several times.
I was treat like a king in modern Y cabin with decent meals, and a big smile
from the most beautiful flight attendant I have ever seen in the sky.
When I told my colleague that I would fly SU.
They just laughed at me.
Ignorance will not help to broaden one's own insight.
When was the last time SU was involved in an accident?
