A PR Week/OnePoll survey of the public this week revealed that the airline's activities, which included a 'Don't Fly' advertising campaign, were cited by 16 per cent of respondents as having the most impact.
EDF came second with 14 per cent, while Adidas - whose 'Take the Stage' integrated campaign featured pictures of athletes in unconventional poses - was ranked third with 12 per cent.
Adidas retained its crown as the brand most associated with the Games, with a quarter ranking it top. This was an increase of four per cent on its position in PRWeek's pre-Games survey.
However, the Government's post-Olympics plans fared less well.
Fifty-one per cent said they did not trust the Government to bring about a legacy of sport - a key shift in PR strategy after the Games - compared with 26 per cent who did.
Paralympics broadcaster Channel 4 has a tough act to follow after 78 per cent of people said the BBC's coverage of the Games was 'good' or 'very good'.
