ABSTRACT
The identification of the determinants of airport hub demand, unavoidable in the recent context of the Air France-KLM integration treaty, is clearly of a general interest because competition among airports is widespread and measurable, as the detailed studies by Mandel (e.g. 1999a, 1999b) have shown for Germany. As our focus cannot be that of a survey of the literature on airport competition, we simply ask to what extent key features of current air demand modelling practice and its trends can be useful in understanding the general question of air market development simultaneously with that of the competition among airports.
