Flying Officer Gordon Percy Olley MM was a World War I flying ace who later formed his own airline, Olley Air Services. He was the first pilot to fly one million miles in total.

Morton Air Services was one of the earliest post-World War II private, independent British airlines formed in 1945. It mainly operated regional short-haul scheduled services within the British Isles and between the United Kingdom and Continental Europe. In 1953, Morton took over rival independent UK airline Olley Air Service. In 1958, Morton became part of the Airwork group. Morton retained its identity following the 1960 Airwork — Hunting-Clan merger that led to the creation of British United Airways (BUA). The reorganisation of the BUA group of companies during 1967/8 resulted in Morton being absorbed into British United Island Airways (BUIA) in 1968.
