The author proposes and tests a model for assigning passenger traffic in a multiple-airport system. The supply side of the system is treated as endogenous and is based on the principle that as traffic using an airport increases, the airport gains popularity. This positive feedback effect and the preference of air travelers for airports near their trip terminus are key factors in determining the distribution of passengers in a multiple-airport system. For demonstration, the model is applied to the San Francisco Bay Area, which is served by airports in Oakland, San Francisco, and San Jose. A disaggregate logit airport-choice model is used to estimate airport utility as a function of travel time to trip origin, airport traffic in the origin-and-destination market, and airport enplanements. The calibrated choice model, combined with estimates of the distribution of trip origins, is used to calculate equilibrium market shares. For the San Francisco and Oakland airports, comparisons of equilibria with observed shares reveals high correlation. The model is particularly effective for larger markets.
