Question: What is this Danish charter airline headquartered in Copenhagen which resulted from merging of two airlines and operates at Copenhagen Kastrup Airport?
Context: Conair of Scandinavia A/S was a Danish charter airline which operated between 1965 and 1993.  Established by Simon Spies, it originally had a fleet of Douglas DC-7 aircraft, taken over from Flying Enterprise.  From about 1970, the airline replaced its fleet with Boeing 720 aircraft, bought from Eastern.  From around 1979 these were replaced by the engine stronger version Boeing 720B.  It bought second-hand Airbus A300 in 1987 and in 1991 six new Airbus A320.  The airline was based at Copenhagen Airport.  In 1993, it merged with Scanair to establish Premiair, today Thomas Cook Airlines Scandinavia which still has its base at Copenhagen Kastrup Airport, EKCH/CPH.

It was opened in 1973 as the first of three planned relief airports around Copenhagen.  These plans were shelved shortly after, and the two other relief airports never made it past the planning stage.
