Airline Injury Claims and the Montreal Convention

Injuries on aircraft are mostly mundane — turbulence, a bag from an overhead bin, a service cart, scalding coffee. What is not mundane is the legal framework. On an international flight, a treaty displaces the law you would otherwise expect, sets its own liability rules, limits where you can sue, and imposes a two-year deadline that is far harder to escape than an ordinary statute of limitations.

Quick answer: International carriage is governed by the Montreal Convention. It creates two-tier liability: strict liability up to a threshold in Special Drawing Rights (no need to prove negligence), and above it unlimited liability unless the carrier proves it was not negligent. The deadline is two years under Article 35 and is treated as a condition of the right rather than a tolling-friendly limitation period. Article 33 restricts where you may sue. Article 29 excludes punitive damages. Purely psychological injury is generally not recoverable. A domestic US flight is outside the Convention entirely.

Which Regime Applies

International carriage — broadly, carriage between two states that are parties, or a round trip beginning and ending in one party state — is governed by the Montreal Convention of 1999, in force for the United States since 2003. It applies to death and bodily injury of passengers, and separately to baggage and cargo.

Purely domestic US carriage is not governed by the Convention. Those claims proceed largely under state negligence law, with a heightened common carrier duty in many states — the doctrine our guides to bus accident claims and train accident claims describe. Two federal overlays matter: the Airline Deregulation Act, 49 U.S.C. § 41713, preempts state law claims relating to a carrier’s rates, routes or services, and federal aviation regulation broadly occupies the field of aviation safety standards, which can shape the applicable standard of care even where a personal injury claim itself survives.

A connecting itinerary sold as a single international journey is generally treated as international carriage throughout — including the domestic leg. Which regime governs your flight is therefore not always obvious from where the injury happened.

The Two-Tier Liability Structure

This is the Convention’s most claimant-friendly feature, and it is genuinely favourable.

Tier one — strict liability. For passenger death or bodily injury, the carrier is liable up to a threshold expressed in Special Drawing Rights, the IMF unit of account, without any need to prove negligence. Proving the accident and the injury is enough.

Tier two — above the threshold. The carrier’s liability is not capped, but it can avoid liability for the excess by proving that the damage was not due to its negligence or was solely due to a third party’s act.

The SDR figure is revised periodically under the Convention’s own review mechanism, and it is expressed in SDR rather than dollars, so its dollar value moves with exchange rates as well. Any specific number printed in an article has a shelf life — the current figure should be confirmed rather than assumed.

What the Convention takes away in exchange:

• Exclusivity. Article 29 makes the Convention the exclusive route for covered claims — you cannot plead around it into a more favourable state law theory.
• No punitive damages. Article 29 confines recovery to compensatory damages, so the analysis in our guide to punitive damages does not apply here.
• No recovery for purely mental injury, generally, absent bodily injury.

The “Accident” Requirement

Liability attaches to death or bodily injury caused by an accident on board or in the course of embarking or disembarking.

In Air France v. Saks, 470 U.S. 392 (1985), the Supreme Court defined an accident as an unexpected or unusual event or happening external to the passenger. That excludes an injury flowing purely from the passenger’s own internal reaction to the normal operation of the aircraft — a distinction that matters most in medical-event cases.

But Olympic Airways v. Husain, 540 U.S. 644 (2004) established that crew inaction in the face of a known risk can itself be the accident. That is a significant extension: a failure to respond appropriately to a passenger’s evident distress, or to a known hazard, is not merely an omission outside the framework.

Events that ordinarily satisfy the requirement:

• Turbulence injuries, by far the most common in-flight injury category
• Baggage falling from an overhead bin
• Service cart contact
• Scalding liquid spilled by crew
• Slips in the aisle or lavatory
• Jet bridge, stairway and boarding incidents, which fall within embarking and disembarking
• Crew failure to respond to a medical emergency or a known danger
• Evacuation injuries

And on the other side, Eastern Airlines v. Floyd, 499 U.S. 530 (1991) held purely mental injury unaccompanied by physical injury not recoverable under the Warsaw regime, a limitation generally understood to carry forward.

Where You Are Allowed to Sue

Article 33 restricts the forum to a closed list:

• The carrier’s domicile or principal place of business
• Where the contract was made
• The place of destination
• For death or bodily injury only: the passenger’s principal and permanent residence, provided the carrier operates services there

Filing outside that list generally means dismissal — and because the two-year clock is unforgiving, a dismissal obtained late in the period can effectively end the claim. Forum selection is therefore a threshold decision rather than a matter of convenience.

The Two-Year Deadline

Article 35 sets two years from the date of arrival at destination, the date the aircraft should have arrived, or the date carriage stopped.

The critical distinction: this is generally treated as a condition of the right to damages rather than a statute of limitations of the sort our state-by-state filing deadline reference describes. The consequence is that the tolling, discovery and equitable extension doctrines which sometimes rescue a late state law claim may be unavailable. Treat two years as absolute.

Crashes, Investigations and General Aviation

A commercial crash brings an NTSB investigation, and a rule that surprises people: under 49 U.S.C. § 1154(b), no part of an NTSB accident report may be admitted into evidence in a civil damages action arising from a matter mentioned in the report. Underlying factual material may be reachable by other means, but the investigation’s conclusions are not simply handed to a jury — which is a large part of why these cases require independent expert work.

General aviation — private and small aircraft — sits outside the Convention. Claims run under state law against the pilot, owner, operator, charter company or maintenance provider, plus product liability theories against manufacturers, on the framework in our guide to defective product claims. One federal statute dominates the product side: the General Aviation Revitalization Act of 1994 imposes an eighteen-year statute of repose on claims against manufacturers of general aviation aircraft and component parts. Like any statute of repose, it can bar a claim over an older aircraft regardless of when the crash happened — the same absolute-cutoff mechanism described in our defective product claims guide.

Crew and airline employees injured at work are generally within the ordinary workers’ compensation framework rather than this one — see our guide to workers’ comp settlement amounts by injury type.

Practical Steps

1. Establish whether the carriage was international or domestic, treating a single international itinerary as international throughout — this determines everything else.
2. Report the injury to the crew before leaving the aircraft and ask that an incident report be made; get the report reference.
3. Keep the boarding pass, booking confirmation and full itinerary, which establish the carriage and the contract’s place of making.
4. Photograph the scene and the cause where you can — the bin, the spill, the cart, the obstruction.
5. Get names and seat numbers of witnesses, who disperse internationally within hours.
6. Seek medical care promptly and describe the mechanism precisely, since bodily injury is a precondition to recovery.
7. Calendar the two-year Article 35 deadline immediately and treat it as absolute.
8. Get advice on the permitted forum before filing, not after, and from a lawyer who handles Convention claims specifically.
