Until 1998 the German Airline Lufthansa flew via Venezuela to Quito. After some years of interruption they offer now a codeshare to Quito with the airline Avianca.

Other recommended airlines flighing from European countries to Quito are

1. KLM >> access homepage
2. IBERIA >> access homepage

Following my own experiences I recommend to fly whenever possible with KLM to Quito. For further information, please contact your travel agency.
