The Montreal Convention is an international treaty that establishes clear, uniform rules for liability in the event of death, injury, delay, or baggage loss during international air travel. According to IATA (2026), the Montreal Convention provides a unified legal framework that allows passengers to claim up to 1,288 SDRs for damages related to flight delays, lost baggage, or injury, regardless of the airline's nationality.
This treaty serves as the backbone for modern passenger protection, ensuring that travelers have a predictable path to recourse when international flights do not go as planned. Whether you are dealing with a significant delay or the frustration of missing belongings, understanding this framework is essential for securing your rights in 2026.
What is the Montreal Convention and why does it matter?
The Montreal Convention is a multilateral treaty adopted in 1999 that replaced the older Warsaw Convention system. It standardizes the liability of air carriers for passengers, baggage, and cargo, ensuring that victims of travel disruptions have consistent legal protections across the vast majority of international routes globally.
Key protections for international travelers
- Strict liability for injury: Airlines are held strictly liable for proven damages up to a certain threshold.
- Delay compensation: Passengers can claim damages for losses caused by flight delays, provided the airline failed to take reasonable measures to avoid them.
- Baggage protection: Clear limits on liability for lost, damaged, or delayed luggage.
The Montreal Convention creates a level playing field for passengers worldwide. By removing the need to navigate complex, varying national laws, it simplifies the process of holding international carriers accountable for their operational failures.
How does the Montreal Convention handle baggage issues?
Under the Montreal Convention, airlines are liable for the destruction, loss, or damage of baggage occurring during the period the airline is in charge of it. If your luggage is delayed, the convention allows you to claim reimbursement for essential items purchased while waiting for your bags to arrive.
Limits and documentation
According to the International Civil Aviation Organization (2025), the liability limit for baggage claims is indexed to inflation, currently capped at 1,288 Special Drawing Rights (SDRs) per passenger. To successfully process a claim, you must maintain meticulous records of your travel and expenses.
Always document every expense incurred due to baggage loss. Keeping receipts and filing a Property Irregularity Report (PIR) at the airport is the first step in building a valid claim. If you need assistance navigating these requirements, our team at Compensall, led by Francisca Albuquerque, founder of Compensall, is ready to help.
What are the limits of liability for flight delays?
When a flight is delayed, the Montreal Convention allows passengers to seek compensation for damages resulting from that delay. Unlike fixed-sum regulations like EU261, the convention focuses on actual financial loss, such as hotel costs, missed connections, or prepaid expenses that were rendered useless by the delay.
Proving your damages
- Financial evidence: Keep all invoices for extra expenses directly caused by the delay.
- Reasonable measures: Airlines can avoid liability if they prove they took all necessary measures to avoid the damage or that it was impossible to do so.
- Time limits: Claims must generally be brought within two years from the date of arrival at the destination.
Documentation is the difference between a successful claim and a rejected one. You must be able to prove that the financial loss was a direct consequence of the airline's failure to operate the flight as scheduled.

Frequently asked questions
Does the Montreal Convention apply to domestic flights?
No, the Montreal Convention primarily applies to international carriage between countries that have ratified the treaty. Domestic flights are governed by national laws, though many countries have adopted similar standards to ensure a consistent level of protection for their passengers regardless of the flight route.
What are Special Drawing Rights (SDRs)?
SDRs are an international reserve asset created by the International Monetary Fund. In the context of aviation law, they serve as a stable unit of account to define liability limits, preventing fluctuations in local currencies from unfairly impacting the compensation amounts available to passengers under the Montreal Convention.
Can I claim for both EU261 and the Montreal Convention?
While you cannot be compensated twice for the same loss, these frameworks often complement each other. EU261 provides fixed-sum compensation for delays, while the Montreal Convention allows you to claim for additional financial damages. It is important to distinguish between these two legal paths when filing your claim.
What is the time limit for filing a claim under the treaty?
Under Article 35 of the Montreal Convention, the right to damages is extinguished if an action is not brought within two years, reckoned from the date of arrival at the destination or from the date on which the aircraft ought to have arrived. Do not delay your legal action.
Does the convention cover airline strikes?
Liability for strikes depends on whether the airline could have reasonably avoided the disruption. While many airlines argue that strikes are extraordinary circumstances, courts have increasingly held that if the airline had the power to prevent or mitigate the impact of the strike, they may still be held liable.
Take control of your travel rights
