In the 19th episode of The Persuaders! called “The Morning After”, Brett wakes up in his suite at Grand Hôtel in Stockholm, covered earlier. He discovers that he has married a woman during what appears to have been a very wet previous night. When Brett takes a flight back to London, he leaves Stockholm from Bromma Airport, Stockholm’s city airport.
Bromma Airport is located only 7 kilometers from the city centre and is closest to the city compared to all the other commercial airports in Stockholm. It was opened in 1936, by King Gustav V, when Stockholm urgently needed a proper airport and it was the first airport in Europe to have paved runways from the start. During World War II Swedish and British aircraft flew to the United Kingdom from Bromma Airport.
However the runway of Bromma was too short for the jet age and for intercontinental traffic in the 1960’s (e.g. DC-8), and the capacity limit of Bromma could be foreseen. Therefore Stockholm Arlanda Airport was built. The flight between Stockholm and London in 1972, at the time of filming of The Persuaders! would most likely have taken off from Arlanda. Even though there are several international flights from Bromma today, there are no flights to London.
It is unlikely that any of the principle cast ever were in Stockholm for the filming, since neither Sir Roger nor Curtis are seen outdoors. The interior scenes in the episode were most likely shot in Pinewood with a back projection from various Stockholm locations. Interestingly enough, the back projection from the airport shows airplane hangars from Stockholm’s largest airport, Arlanda instead of Bromma. A DC-9 airplane from Scandinavian Airlines is briefly seen in the background.
We do not learn which airline Lord Brett is using, although a billboard from SAS is visible in the terminal in one scene as well as the DC-9 from SAS.
At present there is a political campaign run by the environmental party, presently in power, to close down the airport, although there is a strong resistance against it. Hopefully the airport will remain open for many many years to come, because where else would Lord Sinclair land the next time?
