His love for the aviation industry was also evident in his lifelong commitment to Cathay Pacific, which his father Jock had bought in 1948. Adrian was on the Board of Cathay Pacific for 40 years, 1965-2005, and he was closely involved in the 1980s traffic rights battle that eventually won Cathay the London route – a watershed moment for the airline – as well as in the negotiations that secured Cathay's position as Hong Kong's international home-carrier post-1997. He later said that he regretted that he had never flown for Cathay as a pilot, though he helped fly "Betsy" – the original DC3 that founded the airline – back to Hong Kong from Australia in 1983.

Adrian's Chairmanship saw the re-establishment of the group's interests in Mainland China after an absence of more than 30 years, as the country began to open up in the late 70s and early 80s. This began with Coca-Cola bottling franchises and was followed by very significant investments in aircraft engineering and property development. He also followed the lead set by his brother John in urging an environmentally and socially responsible approach to operations group-wide.
In retirement, Adrian Swire became Honorary President of the group, "not interfering", as he liked to stress – though, like his father before him, he considered that a week without a visit to Swire's London office was a week wasted.
Outside of the business, he was an Elder Brother of Trinity House in London. He was Chairman of the RAF Benevolent Fund, a trustee of the RAF Museum, President of the Spitfire Society, and served as an Honorary Air Commodore in the Royal Auxiliary Air Force from 1987 to 2000. He was a Visiting Fellow of Nuffield College, Oxford 1981-89 and Pro-Chancellor of Southampton University 1995-2004. He was a Deputy Lieutenant of Oxfordshire, a church warden, and a keen countryman.
The address at Adrian's funeral spoke of Adrian's generosity, his self-deprecation, his sense of fun, and most of all his unerring sense of right and wrong. Adrian's life was "the living embodiment" of the Swire family (and Swire group) motto
Esse Quam Videri, which means
to be, rather than to seem to be. For Adrian himself, it underlined his personal integrity, his modesty and his strong work ethic.
In 1970 he married Lady Judith Compton, who supported him wholeheartedly throughout his career. They had three children: Martha, who lives in England with her family; Merlin, who is Chairman of Swire Pacific in Hong Kong; and Sam, who is an Executive Director in the London office of John Swire & Sons. He had seven grandchildren to whom he was devoted, and they in turn to him.
He would no doubt have been thrilled that at his funeral on 18th September, the beloved spitfire he had once owned and flown flew overhead in tribute. Meanwhile, all over the world, the 128 vessels in the Swire fleet flew their flags at half-mast.
