In August 1970, Ransome Airlines started one of its first branding partnerships with Allegheny Airlines, which would last until June 1, 1982. During that period, Ransome was branding its flights as "Allegheny Commuter", feeding into Allegheny's hub at Pittsburgh International Airport, though the point-to-point network in the north-eastern United States was also kept. This airline co-operation is seen as one of the earliest examples for a true codeshare agreement (Henson Airlines had been the first carrier to operate as "Allegheny Commuter" in 1967). Following the Airline Deregulation Act, Allegheny Airlines was renamed USAir in 1979. The "Allegheny Commuter" name was kept for some years, though, so that Ransome Airlines never operated as USAir Express.
