Definition & Explanation

When cargo fails to arrive at its destination – or arrives in a condition that leaves no residual economic value – the claim is assessed as a Montreal loss under the Montreal Convention 1999 (MC99). MC99 replaced the Warsaw system in most major aviation jurisdictions and provides a uniform liability regime for international air carriage. The air carrier's exposure is capped at a weight-based limit per kilogram; to benefit from a partial exoneration, the carrier must show that the loss was not caused by its own negligence or that of its servants. Shippers and consignees should act quickly: notice requirements are strict, and failure to meet them may bar recovery. Montreal loss is distinct from Montreal damage, where the goods retain some value despite being harmed.
