Condorito, just checked the website and called Chile. The ATP written and flight test at atps iss 1195 US. As regards to LanChile...the best thing to do is go to Chile, convert your license, then go knock on doors. I assume you speak Spanish, if you dont, forget it. They are happy to hire foreign pilots, but your spanish must be spoken like a native for them to consider you.
Good luck Mate!!!!
