Globalization and modern society have imposed a standard whereby most citizens are granted the opportunity to afford a certain journey during their vacation, often more of aforementioned. Passenger transport has advanced over time, especially air transport, which has reached undreamed-of proportions in a very short time, and has enabled it to visit distant destinations with much shorter travel time. Therefore, as with other types of transport, it was necessary to define the directives and conventions so the contracting parties can rely on them in the event of doubtful situations. Certain types of transport are defined through international conventions that apply to them, regulating the relations of the contracting parties. For air transport, this role is played by the Montreal convention, the Bernese convention for railway, and the Athens convention for maritime relations. Numerous examples are present in which the aforementioned conventions have been applied and served as a basis for legal disputes around the world. For the transport of passengers they play an immeasurable role. As time went by, they were upgraded and changed, and will certainly be further improved with regard to technological and infrastructure changes so that carriers and passengers have a clear basis for their rights and obligations.
