Copterline OÜ (Estonia) was the flight operator, and FastClass Oy (Finland, former Line Support Oy) was the parent company, which was responsible for maintenance. The predecessor of Line Support was the Finnish company Copterline Oy (1990–2010).
Copterline has not been operating on the Helsinki-Tallinn route recently. The airline was planning to open the route again in August 2013, but these plans were postponed and later cancelled. Instead the company currently provides helicopter services to the oil and energy sector on the North Sea.
In March 2016, Copterline OÜ filed for bankruptcy for the second time.
