ENPLANED PASSENGER FLIGHT FREQUENCY FUNCTIONS FOR SHORT HAUL AIR TRANSPORT PASSENGER FLOWS

This research investigates the hypothesis that the function relating e nplaned pass angers to flight frequency differs for non-stop vs. conne cting flights. Two short haul models far air transportation era estima ted. each with five levels of service. The first model employs a singl e function relating enplaned passengers to flight frequency for all fi ve service levels. while the second model employs two flight frequency functions. one flight frequency function for each of two levels of no nstop service and a second flight frequency function for each of three levels of connecting service. The explanatory power of the two-flight frequency model exceeds that of the single flight frequency model.
