A methodology for determining the relationship between air transportation demand and the level of service

PREFACE This report represents the results of an exploratory research study investigating the development of a methodology for determining the relationship between the supply of and the demand for air transportation services. Based upon the initial results of this exploratory research, an attempt will now be made to develop more sophisticated models to first analyze the impact of changing technology on the demand for air transportation and second to forecast the fleet requirements for the U.S. air transportation industry in the next fifteen years.
