An injured passenger may seek economic damages, such as medical expenses and lost earnings, plus non-economic damages for pain and suffering. Availability and value depend on the governing law, the injury evidence, and whether the passenger's failure to wear a seat belt contributed to the harm. Severe turbulence can qualify as an "accident" for a covered international trip when it is an unexpected event external to the passenger. The Montreal Convention then provides the liability framework, while applicable domestic law determines which compensatory losses courts recognize.

When can turbulence support an injury claim?
The claim requires bodily injury caused by an accident aboard the aircraft or during embarking or disembarking. In *Schaefer-Condulmari v. US Airways*, a federal court recognized that turbulence may meet the accident requirement when it constitutes an unexpected external event.
Singapore Airlines Flight SQ321 illustrates the physical mechanism. Investigators reported that rapid vertical-acceleration changes likely sent unbelted occupants airborne and then back down, causing injuries to passengers and crew, according to the Singapore Transport Safety Investigation Bureau's preliminary findings. A claimant must still connect the event to a documented bodily injury. medical records, diagnoses, treatment history, and a clear account of how the passenger moved or struck an object can help establish that connection.
Which economic damages could be available?
economic damages cover measurable financial losses caused by the injury. Depending on the applicable law and proof, they may include: Bills, receipts, wage records, tax documents, work restrictions, and medical opinions can establish the amount. Future losses generally require evidence explaining why additional treatment or reduced earning ability is reasonably connected to the injury.
The Montreal Convention does not itself define every recoverable loss. The U.S. Supreme Court's decision in *Zicherman v. Korean Air Lines* explains that the applicable domestic law identifies legally cognizable harm, including whether particular economic losses can be recovered.
- Past and future medical expenses
- Lost wages during treatment or recovery
- Reduced future earning capacity
- Other documented injury-related financial losses
Which non-economic damages could be available?
Non-economic damages compensate for human consequences that do not come with invoices. Pain and suffering may include physical pain, discomfort, and the effect of the injury on daily life, subject to the law governing the claim. These losses still require proof. Treatment notes, testimony about functional limitations, and consistent descriptions of symptoms can show severity and duration.
A serious diagnosis does not automatically establish a particular award. Punitive or exemplary damages serve a different purpose: punishment rather than compensation. They are unavailable under the Montreal Convention, even when a passenger can recover proven compensatory damages. The treaty also cannot be avoided simply by relabeling a covered claim as tort or contract.
Does not wearing a seat belt defeat the claim?
Not necessarily. Article 20 of the Montreal Convention permits full or partial exoneration only to the extent the passenger's negligent or wrongful conduct caused or contributed to the damage. Timing matters. On SQ321, the crew activated the seat-belt sign only eight seconds before the sharp event.
That evidence could affect whether the passenger had a meaningful opportunity to respond; being unrestrained does not by itself prove that no claim exists. Relevant evidence may include whether the sign was illuminated, what warnings the crew gave, when conditions changed, and whether the passenger was seated or moving through the cabin. Still, the U.S. Department of Transportation's passenger guidance warns that unexpected turbulence has seriously injured and killed unbelted passengers and advises keeping the belt fastened while seated.
Which legal framework and limits apply?
The Montreal Convention applies to covered international carriage. A purely domestic flight instead falls under the applicable domestic liability law, so the available claims, defenses, and damages may differ. For covered international travel, the first liability tier increased to 151,880 Special Drawing Rights per passenger effective December 28, 2024.
Above that amount, the carrier may invoke the Convention's specified defense that the damage was not due to its negligence or wrongful act, or was solely due to a third party, as reflected in ICAO's 2024 revised limits. Passengers should preserve boarding records, their itinerary, photographs, witness details, airline communications, medical records, expense receipts, and employment-loss documents. The itinerary is especially important because it can determine whether the Montreal Convention or domestic law governs the claim.
