The emphasis in this paper is on the development of a suitable conceptual and operational framework within which a policy-sensitive empirical travel choice model could be estimated. Functional Measurement and Discrete Choice Theory provide the theoretical base from which models of individuals' choices can be derived. The aim of this paper is to outline a method which is capable of identifying international air fare structures to various destinations that accord with the likely choices of individuals (both current and potential travellers). The information obtained will permit the determination of a reduced-set of feasible air fare structures which represent a compromise with the full range of possible alternatives. Particular emphasis is given to identifying the variation in frequency of choice of international air travel to various destinations as a result of changes in air fare structures.
