The campaign targeted high-value frequent flyers of rival airline loyalty schemes at Heathrow. It put massage areas outside BA's Executive Lounges, supported by posters, leaflets and press ads.
Harrison Troughton Wunderman picked up 17 awards, including six golds.
Other big winners were Tullo Marshall Warren, which won seven awards, and Saatchi & Saatchi with six.
More than 1,000 people attended the awards, held at the Grosvenor House Hotel (see Book of the Night, this issue).
