I also heard some strange stories from KAL but one the other hand according to my experience during the interview they were very nice, friendly, helpful and professional especially during the Sim (I had to fly the A300).
And also some good fiends are flying there (some already for a long time) without having any problems there. But - of course - you always have to stick to their rules (but itīs same where do I come from).
But in fact: right in the moment it seems to be the best commuting contract on a excellent equipment.
