Prior to the Deregulation Act of 1978, the US airline industry was high regulated with licences and routes being approved by the Civil Aeronautics Board. From the 1950s, a number of supplemental air carriers were formed to provide specialized airlift services that catered to markets beyond the point to point services provided by the scheduled airlines.

Transocean L-749 Constellation N9812F possibly at San Francisco or Oakland, circa 1950s.

These supplemental air carriers provided contract services to the US military, as well as specialized charter and cargo services and passenger charters services, both within the US home market and to points outside of the Continental United States. Sometimes there airlines provided wet lease aircraft operations for the mainline scheduled carriers. Typically these small airliners operated the second hand and military surplus transport aircraft and their operations were focused within certain niche markets in which they built up specializations over their years of operations.

Through my many years of collecting 35mm aircraft slides, I am pleased to present an extensive photo collection of many of these supplemental carriers, including the following (all of which provided US and International passenger and cargo charter services unless otherwise noted):

Seaboard World – using C-46, CL-44, DC-8 and 747 aircraft
