ABSTRACT
Airline managers may well perceive a certain condition denoted as a difficulty by logic, but may then find ways to overcome the obstacle. The chapter discusses the value of a positive definition of entry barriers for assessing the effect of predatory measures on entry. It identifies knowledge gaps regarding entry barriers and describes a methodology that may address some of these gaps. The approach should be affordable and manageable with respect to time constraints. In view of this set of requirements, the use of a questionnaire-based survey seems appropriate. The chapter presents the findings of two research projects using this new methodology. The two projects investigated entry difficulties in the aviation markets in Australia/New Zealand, Canada, the European Union and the USA. The findings show that entry into a market is rendered more difficult by predatory behaviour compared to a scenario in which only a single incumbent serves the route.
