ABSTRACT
This article takes stock of the regulatory convergence between US antitrust law and EU competition law in the field of international air transport. The analysis draws a distinction between domestic aviation and international aviation and sets the boundaries of regulatory convergence in international air transportation. Through a comparative analysis of the decisional practice of the U.S. Department of Transportation and the European Commission, it identifies instances of regulatory convergence in: (i) the definition of the relevant market in international airline alliance cases, (ii) the remedies imposed to immunize international airline alliances, and (iii) the duration of the antitrust immunity. It further identifies an instance of legislative convergence in the area of fair competition in international air transport. The analysis addresses the future of regulatory convergence in the post-Covid 19 era and emphasizes the role of the competition authorities in safeguarding consumer welfare.
