The first commercial flight by Silver City departed London Heathrow for Sydney via Johannesburg in late 1946. The following year, Silver City leased its first Bristol Freighter, moved its base to Blackbushe and participated in the airlift of Hindu and Muslim refugees between Pakistan and India. In 1948, control of Silver City passed from the Zinc Corporation to British Aviation Services. In July of that year, the airline inaugurated the world's first air ferry service across the English Channel between Lympne Airport and Le Touquet Airport. In 1948–49, Silver City participated in the Berlin Airlift. In 1949, it established a French sister airline.
