Oh, give me a break.
I've just been through the Korean Airlines training... yes it can be a bit of a slog, but they're still paying you. I found the LCP's (Line Check Pilots) who do the OE (operating experience- they don't consider it to be 'line training') to be helpful and knowledgeable. I even asked them questions and had reasonable answers. Yes, some people have been given a hard time, but that can happen in any airline.
As for the so-called overt racism, if you take the trouble to learn a bit about the people, the country, learn a bit of Korean, they will bend over backwards to help you.
As with any job, it's what you make of it........
