In December 1993 Conair of Scandinavia, owned by the Danish Spies Group and Scanair of the Swedish SLG Leisure Group merged to form a combined charter airline and Premiair was formed on the 01 January 1994.
By the time that Conair and Scanair merged in 1994 to form Premiair the Sunday Scandinavian visitor's had totally declined and I believe that the few charters from Premiair were the final flights. With the changes in aviation and the advent of cheap flights the low cost era had already made an impact on these familiar charter flights by around 1990/91.
In 1992 Braathens SAFE started flying scheduled flights between Norway and London Gatwick Airport and Linjeflyg had moved their charter flights to London Gatwick Airport during the mid eighties although they didn't last long as the airline retrenched into being a domestic airline again before being taken over by SAS Scandinavian Airlines in 1993.
Braathens had bought Transwede Airways in 1996 who had bought Transair Sweden in 1980.
In 1990 Mearsk Air commenced scheduled flights to London Gatwick Airport, ceasing all charters into London Stansted Airport.
Braathens SAFE on the other hand briefly moved their London Gatwick Airport flights to London Stansted Airport in 2001 but returned back to London Gatwick Airport in 2003. Braathens merged with SAS Scandinavian Airlines on the 01 June 2007.
Not many photos of Premiair aircraft at London Stansted Airport but here is one of their DC10-10's just about to land at London Stansted Airport.
