WHAT?

Formally known as the Convention for the Unification of Certain Rules for International Carriage by Air, the Montreal Convention (MC99) is an international treaty adopted in 1999 and in force since 2003. It replaced older frameworks such as the Warsaw Convention, aiming to modernize and harmonize rules on airline liability across borders.

The treaty applies to international air carriage of passengers, baggage, and cargo, where the countries involved are signatories to the Convention. Over 130 countries, including the US, UK, EU, and India, are parties to this agreement.

When and Where Does It Apply?

The Montreal Convention applies to any international flight where:

1. The journey takes place between two member countries, or
2. Even a stopover is scheduled in a different member state, and
3. The transport is for reward (i.e., commercial air travel)

Passengers can file claims not only in the country of departure or destination but also in the country where they normally reside, offering much greater access to justice.

Airline Liability for Injury or Death

The Convention sets out a two-tier system for airline liability in cases of death or bodily injury of passengers

 Tier 1: Strict Liability : Airlines are automatically liable for proven injury or death up to 128,821 Special Drawing Rights (SDRs) — equivalent to around USD 175,000–200,000, depending on current exchange rates. There is also no need to prove fault or negligence.
 

Tier 2: Additional Compensation : For claims above 128,821 SDR, airlines can avoid further liability only if they prove that the damage was not due to their negligence, or It was solely caused by a third party

Compensation Limits Under the Montreal Convention

These limits are designed to ensure that passengers and shippers are compensated fairly for damages — while also protecting airlines from limitless liability.

Advance Payments in Case of Death or Injury

Airlines are obligated to make advance payments to passengers or their families in the case of death or serious injury. The amount is typically no less than 16,000 SDR and must be made within 15 days of identifying the eligible claimant. This ensures immediate financial support for grieving or injured families.

 

Passenger Rights and Time Limits to File Claims

The Montreal Convention grants passengers significant legal protection — even without proving airline negligence (up to the SDR limit). However, strict deadlines apply:

1. Damaged baggage: Report within 7 days

2. Delayed baggage: Claim within 21 days

3. Other claims (injury, death, etc.): File within 2 years

4. Failing to meet these timelines can lead to automatic dismissal of the claim.

Why the Montreal Convention Matters

1. It creates a unified legal standard for air travel liability worldwide.

2. It offers better compensation and legal clarity compared to previous treaties like the Warsaw Convention.

3. It enables passengers to file claims in their home country, improving access to justice.

4. It has built-in mechanisms to update compensation limits with inflation and global economic changes.

The Montreal Convention is the cornerstone of modern aviation law. It brings clarity, fairness, and predictability to air travel — ensuring that passengers, airlines, and cargo operators understand their rights and responsibilities in case of an incident. With rising international air traffic, this treaty continues to play a critical role in global travel protections.
