Montreal Convention montreal-1999

Convention for the Unification of Certain Rules for International Carriage by Air (Montreal Convention 1999)

In plain language

A multilateral treaty governing international flights between countries that have signed it. It does not award a fixed sum; it makes the airline liable for your proven loss up to a limit, expressed in Special Drawing Rights (SDR). It covers checked-baggage loss, damage, and delay, and damage caused by passenger delay. Domestic flights are not covered — national law applies instead.
