The Convention for International Carriage by Air, commonly known as the Montreal Convention, is the primary international treaty governing airline liability for passengers injured during international flights.[1] Enacted in 1999 to modernize and replace the Warsaw Convention, the Montreal Convention seeks to create uniformity and predictability in international aviation law.[2] Despite its modernizing intent, the Montreal Convention leaves unresolved a persistent issue in tort recovery: whether—and under what circumstances—may passengers recover damages for emotional distress.[3]
The Montreal Convention allows for the recovery of damages resulting from bodily injuries; however, courts narrowly interpret its scope, often rejecting claims for standalone emotional distress.[4] Courts have consistently held that the Montreal Convention does not permit recovery for standalone emotional injuries. However, ambiguity remains where emotional harm accompanies physical injury.[5]
The Montreal Convention governs the liability of air carriers in international travel.[6]It applies to all international carriage of persons, baggage, and cargo performed by aircraft for reward between signatory states.[7]Article 17(1) provides that a carrier is liable for “the death or bodily injury of a passenger caused by an accident on board the aircraft or in the course of embarking or disembarking.”[8] Absent from Article 17 is any reference to emotional distress or psychological injury.[9] As a result, courts have interpreted “bodily injury” narrowly to exclude emotional distress that is not accompanied by a physical injury.[10]
In the landmark case Eastern Airlines, Inc. v. Floyd, the Supreme Court of the United States held that, under the Warsaw Convention, passengers cannot recover damages for emotional distress when not accompanied by physical injury.[11] The Court emphasized that “bodily injury” is not a term that includes purely mental or emotional harm, especially in the absence of clear textual support in the treaty.[12]Notably, the Court in Floyd discussed that the original French text of the Convention uses the phrase “lesion corporelle,” which translates specifically to physical or bodily harm, further underscoring the exclusion of standalone emotional injuries.[13] Although Floyd was decided under the Warsaw Convention, the Court’s holding was extended to the Montreal Convention due to nearly identical language in Article 17.[14]
The Court reaffirmed the Floyd narrow treaty framework in El Al Israel Airlines, Ltd. v. Tseng, where it held that the Warsaw Convention preempted state-law claims for emotional distress.[15] The logic from Tseng also extends to the Montreal Convention, preventing passengers from circumventing the treaty’s limits by pleading alternative theories under domestic law.[16]
Although standalone emotional distress is not compensable, courts have permitted recovery for emotional damages where they stem directly from or occur alongside a bodily injury.[17] In Doe v. Etihad Airways, the Sixth Circuit allowed a claim under the Montreal Convention to proceed where a hypodermic needle left in the airplane seat pricked a plaintiff, causing emotional trauma.[18] The court reasoned that the plaintiff’s emotional distress damages were recoverable because they were the “consequence of a bodily injury,” satisfying Article 17.[19] Similarly, the Eighth Circuit in In re Air Crash at Little Rock held that damages for mental anguish were permissible where the plaintiff had sustained physical injuries and post-traumatic stress disorder following an onboard accident.[20] Doe and In re Air Crash at Little Rock illustrate the narrow path plaintiffs must tread to recover for emotional harm. The emotional distress must be linked to a physical injury.
Still, courts often struggle to delineate the threshold for what constitutes a bodily injury. Plaintiffs who allege physical symptoms of emotional trauma—such as insomnia, nausea, or anxiety—face an uphill battle if they cannot demonstrate that the symptoms themselves amount to a physical injury. Plaintiffs have argued, with expert testimony, that PTSD may cause chemical changes in the brain, which can be found to be a physical injury. However, courts have not yet adopted such creative arguments.
Defenders of the current interpretive approach argue that allowing recovery for emotional distress would “open the floodgates” to litigation, undermining the Convention’s goal of predictability for international carriers.[21]Airline incidents often involve emotional discomfort, ranging from turbulence to crash dynamics, and recognizing such claims could lead to overcompensation and legal uncertainty.[22]
Critics argue that the Convention’s restrictive interpretation of “bodily injury” is out of step with modern science, which increasingly recognizes the debilitating effects of psychological trauma.[23]Legal scholar Erica Clark Jones contends that courts should recognize emotional injury as a legitimate harm, particularly in cases involving traumatic onboard events such as crashes, clear air turbulence, hijackings, or other severe incidents that medical science increasingly acknowledges can cause psychological injuries that are comparably serious and as impairing as physical injuries.[24]
Courts continue to grapple with how to address emotional distress claims under the Montreal Convention. In Bobian v. CSA Czech Airlines, passengers brought claims after experiencing extreme turbulence during a transatlantic flight that flew through Hurricane Floyd, claiming harms of emotional distress and physical manifestations of that distress.[25]One plaintiff, who suffered a heart attack, was permitted to proceed with their claim. However, the court rejected the remaining plaintiffs’ claims based solely on emotional trauma or related symptoms, such as PTSD, holding that such injuries did not meet the Convention’s requirement of “bodily injury.”[26] Bobian poses the scenario of passengers overcome with fear during a flight, convinced that the aircraft is about to crash and fearing death. In such cases, critics ask: where should courts draw the line between physical emotional harm? Should such an event not be compensable? Cases like Bobian highlight the tension between evolving scientific understanding and the Convention’s restrictive legal framework, raising difficult questions about justice and the limits of legal redress in the face of modern air travel risks.
The Montreal Convention offers clear protection for passengers injured during international air travel, but only up to a point. While emotional distress damages are generally unavailable on their own, they may be compensable when linked to bodily injury. To date, most courts have interpreted this standard strictly, maintaining consistency with treaty language and international uniformity. As air travel continues to grow and as a legal understanding of mental health evolves, courts and policymakers may face increasing pressure to reevaluate the scope of “injury” under Article 17. Certainly, international airlines have outgrown the fledgling initial stages where the Warsaw protections were needed. Until then, passengers must demonstrate physical harm as a gateway to recovering for emotional trauma under the Montreal Convention.
