The subject of this master's thesis is the analysis of international jurisdiction within the framework of contracts for air passenger transport. The thesis examines the development of the case law of the Court of Justice of the European Union in determining the competent court in disputes between airlines and passengers. The relevant instruments are Regulation Brussels I bis and Regulation 261/2004. Regulation 261/2004 contains provisions under which passengers initiate proceedings, while Brussels I bis Regulation contains provisions regarding which court will have jurisdiction in case of disputes. The aim is to determine, based on the general terms and conditions of airlines within the European Union, whether the general terms and conditions of airlines contain a provision specifying the competent court in case of disputes, i.e., a jurisdiction clause. Through the analysis of this topic, it was determined that the airlines Ryanair, Wizz Air, and Austrian Airlines include a jurisdiction clause in their general terms and conditions, while other analysed airlines in the European Union do not include such clauses and international jurisdiction is subject to provisions on special jurisdiction for matters relating to contracts. Additionally, it is analysed which court will be competent based on the provision on special jurisdiction for contracts in the case of direct flights, as well as in cases of two or more connected flights.
