Dear condorito:
If you want to get into LanChile all you have to do is convalidate your licence to the chilean one, no need to get the FAA licence. Entry requirements vary according to need. But growth has been steady for the last few years. Best bet is to go get your Chilean licence an apply. They have taken two hundred hour pilots and trained them themselves in the last couple of years. And now LanChile Cargo is expanding rapidly. Be advised that if you want to get rich better go elsewhere. GodSpeed Condorito!
