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.

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.
