Copterline operated with two S76 between Helsinki Hernesaari heliport (EFHE) and Tallin Linnahall Heliport (EECL) from spring 2000. Operations included daily flights between cities, taking around 18 minutes one way. Before October 2005, flights had 1300-1500 passengers every week. Flights were stopped in 2006 due to low passenger loads after loss of OH-HCI in a fatal accident in October 2005. A couple of attempts have been made to restart services, like 2008, but they have turned out to be rather short-lived due to passengers numbers too low to keep service economically viable. Later registrations SE-HAJ and N9483.
