What document defines the rights and obligations of air shippers and carriers?

The Warsaw Convention is the correct answer because it specifically addresses the rights and obligations of air shippers and carriers in international air transport. Established in 1929, it provides a legal framework that governs issues such as liability for cargo loss, damage, and delay, as well as regulations regarding ticketing and the transportation of passengers. The purpose of the Warsaw Convention is to create a uniform set of rules that ensure that carriers and passengers know their rights and responsibilities, thereby facilitating international air travel and trade.

Other conventions, while important in their own right, serve different purposes. The Montreal Protocol updated some aspects of the Warsaw Convention, particularly regarding liability but does not redefine the core rights and obligations established by the Warsaw Convention. The Hague Convention primarily deals with the transportation of goods by sea and not specific to air transport, while the Chicago Convention focuses on the regulation of international aviation standards, air navigation, and the rights of states regarding air traffic. Therefore, the Warsaw Convention stands out as the foundational document for air transport rights and obligations.
