This handbook is the result of four years of teaching European Union Transport Law to the law students of the University of Roma Tre. The handbook is divided into four modules, reflecting areas where the intervention of EU law has been most significant: air transport, rail transport, port services and passengers’ rights. With the evolution of transport regulation in the EU in these last years and thanks to the success of the first edition (over 2000 downloads in 18 months), we have considered it useful to expand the topics presented in this primer. In particular we have added in this second edition a specific module on the painstaking process of opening port services to competition. Furthermore a paragraph has been added on the Single European Sky (SES) programme. The second part of the handbook includes the most relevant judgments and decisions by the EU Courts and Commission which we found particularly useful to illustrate, from a practical point of view, the policies underlying EU transport law and the conflicting interests of the various stakeholders.
