The purpose of Air Transportation: Foundations for the 21st Century, and its companion, Airline Management: Strategies for the 21st Century, is to acquaint the reader with the principal elements of air transportation history, airline economics, business, finance, marketing, regulation, and management--to bring all the essential elements of commercial aviation within these two books. Together, they take readers through the dark ages and monumental losses suffered collectively by the airlines since deregulation, and into the possibility of an economic reformation and the return of profitability. Suggested are trends and stategies that if followed by all stakeholders might lead to a renaisance of consistent profitability for the airlines, stable employment for labor, and continuous, reliable and fairly priced air services for consumers.
