Copterline Oy was Finland's largest helicopter airline established on 15 October 1990 as Copter Action and renamed to Copterline in 2000. In 2004 the company ferried over 75,000 passengers. On December 19, 2008, Copterline confirmed that it had ceased its scheduled service between Helsinki and Tallinn. On 15 February 2010, Copterline filed for bankruptcy, citing inability to keep the company profitable. Its head office was located on the grounds of Helsinki-Malmi Airport in Helsinki. In 2011, Line Support Oy, founded by mostly the same group as Copterline Oy, announced a resumption of service from September, operated by its Estonian subsidiary Copterline OÜ. On 9 September 2011, the first commercial flights were undertaken. History Copterline acquired Helikopteripalvelu in 1999, the oldest Finnish company in the business, and began offering services in 2000. Copterline used to maintain hourly passenger flights across the Gulf of Finland between Helsinki, Finland (Helsinki Hernesaari Heliport) and Tallinn, Estonia (Tallinn Linnahall Heliport) between 07:00–20:00 (14 round trips), 9:00–17:00 on Saturdays (9 round trips) and 10:00–16:00 on Sundays (7 round trips). The trip took 18 minutes, and the helicopters could carry 12 passengers on each flight. On 10 August 2005, Copterline Flight 103 crashed while flying between Tallinn and Helsinki, three kilometers south of Aegna island. All 14 people on board died. After that tragic accident, the company closed the route. In August 2006, Copterline sold its last remaining S-76 and focused on charter flights resuming the route between Helsinki and Tallinn on April 9, 2008, with a new AgustaWestland AW139 helicopter. The company was planning a new terminal in Helsinki. In August 2008, a second AW139 entered into the fleet, and started operating in the same route. Kaj Takolander became CEO of the company. On 19 December 2008, Copterline confirmed that it had ceased its scheduled service between Helsinki and Tallinn and was now looking at the possibility of alternative uses for its helicopters, otherwise, it will sell or lease its aircraft. As of September 2011 the Copterline website was back in service with a flight schedule advertising flights up until the Christmas period. The new service was operated by the Estonian company Copterline OÜ with an AgustaWestland AW139 helicopter owned and operated by the Finnish company FirstClass Oy.
