Well ... I have to agree with Wasila in most of the issues.. some like english and ATC still have to be addressed, but then again that counts for mostly all of non english asia...
I got more than 11.000 hours on 747-400 alone and I can tell you that working with KAL will be ease or hard ...all depends in where you come from and what would be your attitude for training... after been in Asia for 14 year... I can say that KAL is one of the good companies.. yes, it has it bad things... but also good ones. If you are looking to come to asia is because you need the job or the experience..... come and see for yourself... try to get a leave of absent at work while you finnish training in KAL.... then decide..
747-400 is $13.070 after paying for the insurance plus perdiem around 800 to 1000 depends on your flights 65 to 75 hours... but is more because only counts stick time..
Good luck
