If you look at the KFA website under "minimum requirements" it already states that you have to be fluent in the Dutch language. It is funny that the website of KFA is only available in Dutch without the option to read it in English (
KLM FLIGHT ACADEMY) So basically, KLM expects you to learn Dutch before you can even read their training website, very clever!!!! If you go to for example Lufthansa Flight Training the website is in English with the option to read it in German (
www.lufthansa-flight-training.com).
I am Dutch, non KFA trained and one of many foreign nationalities flying for BA........and HAPPY. It is nice to have colleagues with a different background like ab-initios, regionals, low cost and military. No need to be painted in the colours of the Union Flag!!
