Montreal Convention Passenger Rights: What Injured Airline Passengers Need to Know

If you’ve been hurt on an international flight or your bags went missing, you likely have rights under the Montreal Convention. This international treaty governs airline liability for passenger injury, death, and baggage issues on international flights between member countries. Here’s what you need to know to protect yourself and seek compensation.

Key Takeaways

• The Montreal Convention was established in 1999 and applies to international flights between over 140 countries. It creates a uniform set of rules for airline liability covering bodily injury, death, and baggage problems.
• Airlines are liable for passenger injuries up to 113,100 SDR (approximately $200,000) without passengers needing to prove the airline’s negligence. This simplifies the legal process for injured passengers significantly.
• Current SDR caps also cover delayed baggage (up to approximately $1,950 for lost luggage) and passenger delay (up to approximately $8,200), with periodic adjustments by ICAO.
• For claims exceeding 100,000 SDRs, airlines must prove they were not negligent or that a third party was solely at fault. Below that threshold, the carrier is strictly liable.
• All Montreal Convention claims must be filed within two years of the incident. Early legal advice is critical in serious airline injury cases to avoid missing hard deadlines.

What Is the Montreal Convention and When Does It Apply?

The Montreal Convention (MC99) is an international treaty created by the International Civil Aviation Organization to unify airline liability rules for international air travel. It entered into force on November 4, 2003, replacing the older Warsaw Convention framework with clearer, more consistent protections for airline passengers.

MC99 applies to “international carriage” between two different member states, or within one state with an agreed stop in another. Here are concrete examples:

1. New York to London – covered, as both the U.S. and U.K. are member states.
2. Paris to Tokyo – covered under the same principle.
3. Toronto to Cancún – covered, since Canada and Mexico are both parties.
4. Los Angeles to Chicago – generally not covered, as this is a purely domestic flight.

The convention applies to international flights between approximately 140 countries, but a patchwork of regimes still exists where states have not ratified. For domestic flights, national negligence and consumer laws govern passenger rights. On covered international flights, local laws cannot be used to bypass the rules of the Montreal Convention – it preempts conflicting local tort law in airline injury cases.

Airline Liability for Passenger Injury and Death Under the Montreal Convention

MC99 imposes what legal experts call “virtual strict liability” for bodily injury or death caused by an accident on board or during embarking or disembarking. Airlines are liable for passenger injuries under the Montreal Convention without passengers needing to prove the airline was at fault – up to a set threshold.

Key points about airline liability:

• Airlines are liable for injuries up to 113,100 SDR per passenger under the strict liability tier. No proving liability or airline’s negligence is required.
• Airlines have a duty to ensure passenger safety during flights. This covers common in flight injuries from turbulence, an overhead bin falling, spilled hot beverages, or a service trolley striking a passenger.
• Airlines must prove they were not negligent for claims over 100,000 SDRs. Compensation for damages can exceed 100,000 SDR under certain conditions when the carrier cannot demonstrate absence of fault.
• You can claim for damages up to 200,000 SDRs for injuries in cases involving further liability beyond the strict threshold.

This legal framework applies exclusively to covered international flights and sets the ground rules for personal injury claims, making it the dominant avenue for airline injury claims on international routes. Major airlines are required to carry liability insurance to meet these obligations.

Two‑Tier Liability System and SDR Compensation Limits

The Montreal Convention uses a two-tier system to determine carrier liability. Compensation is calculated in Special Drawing Rights (SDRs), a basket currency maintained by the International Monetary Fund – not in any single national currency. The convention sets maximum limits for airline liability measured in SDRs.

Under the first tier, airlines are strictly liable up to the lower SDR limit for a passenger’s injury or death. Above that amount, the airline faces further liability unless it proves no negligence or sole third-party fault.

ICAO periodically revises these limits to account for inflation. Here are the approximate current caps:

Claim Type	SDR Limit	Approximate USD
Death or bodily injury (strict liability)	151,880 SDR	~$200,000
Passenger delay	6,303 SDR	~$8,200
Baggage loss, damage, or delay	1,519 SDR	~$1,950
Cargo (per kg)	26 SDR/kg	~$35/kg

Damages for passenger delay have a cap of 6,303 SDRs per passenger, meaning compensation for delayed flights can reach up to $8,200. Compensation for lost or damaged luggage is capped at $1,950. Airlines are strictly liable for checked baggage they have in custody.

What Counts as an “Accident” Under the Montreal Convention?

Not every injury on a plane qualifies for Montreal Convention compensation. Case law – starting with Air France v. Saks – defines an “accident” as an unexpected or unusual event external to the passenger. The accident must have occurred on board the aircraft or during embarking or disembarking.

Compensable accidents include:

• Luggage falling from an overhead bin onto a passenger
• Being struck by a service trolley pushed by airline personnel
• Serious burns from spilled hot beverages when airline staff failed to secure lids
• Slipping on icy airstairs while boarding due to faulty equipment or conditions the airline failed to address
• Failure to provide adequate medical attention when the situation clearly demanded it

Non-compensable scenarios typically include deep-vein thrombosis from prolonged sitting (no external event), ordinary ear pressure changes when cabin systems worked as designed, and physical pain from pre-existing conditions unrelated to any airline action.

Purely psychiatric or mental injuries without any accompanying physical injury are generally excluded. Emotional distress alone – such as fear experienced during severe turbulence – does not qualify unless tied to a documented bodily injury. Bystander claims from fellow passengers watching someone else get hurt are also usually rejected.

Baggage, Delayed Baggage, and Mobility Equipment Rights

MC99 governs airline liability for lost luggage, damaged baggage, and delayed baggage on international flights. Airlines are strictly liable for checked baggage in their custody, and passengers can seek compensation for proven losses up to the SDR cap.

If baggage is delayed, the airline must reimburse passengers for essential replacement items – think emergency purchases like toiletries and clothing. Baggage is officially deemed lost if it is not received within 21 days of the expected delivery date.

Critical reporting deadlines:

• Damaged baggage must be reported within 7 days of receipt
• Delayed baggage must be reported within 21 days of receiving the bag
• A written report must be submitted directly to the airline in all cases

For disabled passengers, mobility equipment like wheelchairs or scooters is treated as baggage under MC99 caps, which often undervalues high-cost aids. However, some jurisdictions – including the European Union under Regulation 1107/2006 and U.S. federal regulations – require airlines to provide full replacement value outside MC99 limits.

Steps to start a baggage claim at the airport:

1. Visit the Lost Luggage desk immediately upon arrival
2. File a Property Irregularity Report (PIR) with airport employees
3. Retain your boarding passes and baggage tags
4. Keep all receipts for emergency purchases
5. Send a written complaint to the airline within the MC99 deadlines above

Domestic Flights vs. International Flights: Which Rules Apply?

On domestic flights, passengers generally must prove airline negligence to recover damages for an airline injury. National tort law, federal regulations, and consumer protection statutes – including those enforced by bodies like the Federal Aviation Administration – apply instead of MC99.

On international flights between member states, the Montreal Convention makes proving carrier liability much simpler up to the strict-liability threshold.

Common scenarios at a glance:

• Domestic U.S. flight: State tort law plus federal regulations; must show the airline failed to exercise reasonable care
• EU-only route: EU passenger rights regulations plus internal national law
• Cross-border EU–non-EU route: MC99 applies as the primary legal framework, potentially supplemented by local regimes

The same turbulence accident occurred on two different routes can produce entirely different rights depending on whether the ticketed journey qualifies as international carriage. Multi-segment itineraries are assessed as a whole – if the origin and final destination are in two different states on a single ticket, the entire international trip is covered by MC99, even when one leg is domestic.

How to Make a Claim Under the Montreal Convention

Injured passengers should act quickly. Documentation and compliance with notice deadlines can make or break compensation claims.

For airline injury claims:

1. Report the incident to airline staff and flight attendants immediately
2. Complete an in-flight incident report before landing
3. Seek immediate medical attention and retain all medical records
4. Document all expenses related to the injury for claims – medical expenses, lost wages, and receipts
5. Contact the airline in writing within 60 days of injury
6. File a formal claim under the Montreal Convention within two years

Airlines must keep a record of customer complaints, so always communicate in writing.

For delayed or damaged baggage:

1. File a Property Irregularity Report at the airport
2. Keep boarding passes, baggage tags, and all receipts
3. Send written complaints within 7 days (damage) or 21 days (delay)

If the airline denies or minimizes your claim, consult an aviation law attorney experienced in airline injury cases and international airline liability. Claims for personal injury must be filed within two years of the incident – courts treat this as a hard cutoff.

Special Issues: Disabled Passengers, Medical Attention, and Psychiatric Injuries

MC99 does not itself create a full disability-access regime, but it interacts with disability rights laws. Failure to provide requested wheelchair assistance during embarking or disembarking can be treated as an “accident” if it leads to bodily injury, making a claim under the Montreal Convention possible.

Damage to mobility equipment is treated as damaged baggage under MC99, but regional laws may give disabled passengers broader protection, including full replacement value regardless of the liability limit.

Failure to provide reasonable in-flight medical attention – or to divert when clearly required – can itself qualify as an unexpected external event, potentially triggering airline liability. If airline staff failed to warn passengers about known risks or provide adequate assistance, this strengthens the case.

Purely psychiatric injuries generally fall outside MC99. However, mental injuries linked to physical harm – such as PTSD after a burn or fracture – may be compensable as part of overall damages in many jurisdictions.

Compensation Types and How Courts Calculate Damages

MC99 allows recovery for “damage sustained” – not fixed, automatic payouts. Montreal Convention compensation depends on documented evidence of actual loss.

Typical recoverable items include:

• Medical expenses and rehabilitation costs
• Lost wages and loss of future earning capacity
• Pain and suffering (where permitted by local law)
• Funeral costs and loss of support in fatal airline accidents

Passengers can claim compensation for economic harm caused by flight delays or cancellations, subject to the SDR caps. An airline is liable for damages caused by a flight delay unless they prove reasonable measures were taken to avoid it. Airlines can be exempted from paying damages if they prove that the loss was due to passenger negligence or the passenger’s own negligence.

Courts convert the SDR limits into local currency at the date of judgment, then assess documented losses within that cap. For example, if a passenger suffered burns requiring $150,000 in treatment, that falls within the strict liability tier – no need to prove airline’s negligence. Air carriers cannot invoke defenses below the threshold.

Jurisdiction, Deadlines, and Litigation Strategy

MC99 strictly limits where and when passengers can sue. For serious international airline injury claims, forum selection directly affects outcomes.

Passengers can generally sue in one of several places: the carrier’s domicile, its principal place of business, the place of ticket purchase, or the passenger’s final destination. Some jurisdictions also allow suits where the passenger resides.

Claims under the Montreal Convention must be filed within two years of the date of arrival or expected arrival. Many courts treat this as a hard cutoff – not subject to ordinary extensions. It protects passengers by standardizing compensation for delays and baggage issues, but it also requires airlines and passengers alike to act within firm boundaries.

Early consultation with a lawyer experienced in aviation law is essential. MC99 preempts most state-law personal injury claims for covered international flights, so lawsuits must be framed as Montreal Convention claims. Other airlines or air traffic control entities involved may require separate proceedings.

The Montreal Convention gives passengers important legal protections when injuries, baggage loss, or flight delays occur on international flights. By establishing uniform airline liability rules and clear compensation standards, it makes it easier for injured passengers and grieving families to pursue financial recovery. However, strict reporting requirements, two-year filing deadlines, and complex international legal rules mean that acting quickly is essential to protecting your rights.

FAQs About Montreal Convention Passenger Rights

Below are answers to common follow-up questions about Montreal Convention passenger rights.

Can I claim compensation for missed connections and extra expenses?

MC99 allows recovery of actual, provable financial losses from delay – hotels, meals, replacement clothing – subject to SDR caps. Compensation for delayed flights can reach up to $8,200 per passenger. However, the Convention does not provide automatically set compensation amounts for delays. You must keep all receipts, and airlines may argue that extraordinary circumstances justify reduced liability. The Montreal Convention does not mandate specific amenities for delayed passengers; recovery depends on proven, reasonable expenses.

Does the Montreal Convention cover only the international leg of my trip?

When tickets are issued as a single contract with origin and final destination in two different states, the entire itinerary is treated as one international carriage. A domestic segment like Dallas to New York connecting to New York to Paris on one ticket is fully covered by MC99. Separate tickets bought independently for a canceled flight or rerouting mean the purely domestic part may fall under national law.

Do I need a lawyer for a Montreal Convention claim?

For straightforward delayed baggage or minor expense claims, passengers often negotiate directly with the airline using MC99 rules. For serious bodily injury, long-term disability, or death, legal representation is strongly recommended due to complex jurisdiction and the need for proving liability above the strict threshold. Early legal advice prevents missed deadlines and helps secure the compensation you deserve for medical expenses, lost wages, and pain and suffering.

Can airlines reduce my rights through their contract of carriage?

MC99 is an international treaty that generally overrides conflicting airline contract terms for covered international flights. Air carriers cannot legally contract out of core Montreal Convention passenger rights. However, some airlines voluntarily offer higher baggage limits or additional adequate assistance beyond what requires airlines to provide under MC99. Review both the Convention rules and the carrier’s conditions of carriage.

Are purely emotional or psychiatric injuries ever compensated?

MC99 is limited to bodily injury, so purely psychiatric conditions without physical harm – like fear of flying after a severe scare – are usually not compensable. Where a passenger suffers both physical injury and mental harm (for example, a fracture plus PTSD), courts in many jurisdictions allow recovery for the psychiatric component as part of overall damages. National courts differ in how broadly they interpret “bodily injury,” so outcomes vary by country even under the same Convention framework.
