Airfrance and GOL Linhas Aéreas or LATAM Airlines and are currently selling pretty cheap tickets from Germany, Berlin, Hamburg, Stuttgart, Nuremberg etc., to Santiago (Chile). I found availability during October and November.
Flight times are quite ok, maximum layover is 3,5 hours. You’ll connect only in Paris CDG on the outbound and in South America (e.g. Lima) and Paris on the inbound journey.
