only 1/3rd or so can be expect to get a job with KLM
That's BS. 92% of the KLS graduated got hirred last year. A few of the rest 8% already got a job elsewhere. KoKo??? It is CoCo in Co Co Pilot (Second Officer).
You can join KLM Flight Academy as an English guy. However, the Groundschool is given in Dutch, by Dutch teachers. But all the Lecture is English also the Exams. I say, just go for it.
If you don't finish the school a found will pay for your debts. So no problem.
