To provide a comprehensive account of the EU’s role in the travel sector, this chapter describes the specifics of the common transport policy. The key competence norm in Article 91 TFEU is analysed and its considerable potential is discussed. Ultimately, the conclusion is similar to that reached in the previous chapters: despite a wide range of passenger protection measures, users of online travel platforms remain out of the picture. At the same time, existing legislation can be a valuable reference moving forward.
