Montreal Convention
The Montreal Convention (formally, the Convention for the Unification of Certain Rules for International Carriage by Air) is a multilateral treaty adopted on 28 May 1999 by member states of the International Civil Aviation Organization (ICAO) and entered into force on 4 November 2003. It updated and replaced parts of the earlier Warsaw Convention and Hague Protocol, which had governed international air travel since the early 20th century.
