AF Stadler, Sonja AU Stadler, S AB During the last decade, traditional network carriers have been challenged by the rapid growth and rising market share of low-cost carriers. Especially on short-haul routes, network carriers have been forced to alter their strategies in order to remain competitive. Therefore it is vital for airlines to gain knowledge about the needs and preferences of their customers in order not to lose them. By understanding how passengers decide between different flight carriers, airlines are able to customize their product and thus make it more attractive. In order to ascertain passenger characteristics and flight preferences, a survey at Zurich Airport was conducted with both low-cost and SWISS passengers. The questionnaire contains a choice question according to the choice-based-conjoint-analysis with which it is possible to detect the partworths of certain airline attributes. The first part of the paper is dedicated to existing literature and theory about customer value in air transport, passenger choice behaviour and airline pricing models. This is followed by an empirical part as well as an analysis and discussion of the results obtained. ER
