Research about the consequences of air transport liberalisation in the European Union is already substantial in amount and scope. Nevertheless, spatial implications of this liberalisation have not been fully addressed yet. By analysing information from the OAG database, this paper measures the geographic concentration of air routes and seating offers supplied under competition conditions among European airports. Our analysis demonstrates that competition is mainly restricted to European World Cities, the ones which concentrate high‐rank functions in the capitalist world‐economy.
