The book describes the history of many of the airlines that flew from North America up until '85. It is divided in seven parts: Aircraft Design/Airline Usage, Major Airlines, Large Regional Airlines, Regional And Third Level Commuters, Other Carriers, Cargo Carriers and Airport And Airline Operations.
Strangely, although the book contains information about Canadian airline companies, it does not include any information on Mexican airlines, even though Mexico is, geographically speaking, the southernmost part of North America.
