While the benefits and privileges of IATA as a trade association are significant and cannot be underrated, its massive foray into the domain of economic regulation has given rise to serious questions. Disputes relating to the structure and its quasi international regulatory power have already been addressed by national courts and regulatory authorities but no common or uniform guiding principles have emerged whereby IATA rules and their legitimacy could be evaluated on a universal scale.This book comprises an in-depth study of this conflict and its relevance for the airline consumer. It also discusses and proposes solutions on an international scale. It is thereby intended to serve as a valuable source of information that will inspire further deliberations on the subject and as a useful working tool for scholars and practitioners alike.
