What to Do If an Airline Loses Your Luggage

The moment you realize your luggage did not arrive, go directly to the airline's baggage service desk — do not leave the airport without filing a claim. Get a Property Irregularity Report with a reference number before you walk out that door. This document is your proof and your ticket to compensation.

For international flights, the Montreal Convention entitles you to compensation for delayed or lost baggage. Keep all receipts for essential items you purchase while waiting — toiletries, a change of clothes — as these are typically reimbursable. Follow up with the airline in writing every few days. If the bag is not found within 21 days, it is officially considered lost, and you can file for full compensation.
