ESTIMATING THE MARKET SHARE OF INTERNATIONAL AIR CARRIERS

United States flag carriers and aviation authorities are currently participating in a large number of activities that promise to alter the structure of the international air-transport network. There is a pressing need to develop methods for estimating the share of traffic that U.S. carriers can expect to attract under the various alternatives being considered. To meet these needs, a new method called the international quality-of-service index (IQSI) has been developed. It is derived from the quality-of-service index (QSI) method developed by the staff of the Civil Aeronautics Board for domestic-route cases and augments the old QSI method by considering (in addition to frequency, aircraft type, and number of stops) the impact on market share of citizenship loyalty to flag carriers. Use of IQSI essentially eliminates the biases inherent in the old QSI method and reduces the average prediction error by more than 25 percent. (Author)
