Olympic Airways v. Husain
The Supreme Court ruled that an airline can be held liable under the Warsaw Convention when a flight attendant's unusual refusal to help a passenger contributes to his death, even though the attendant's conduct was a failure to act rather than an affirmative act.
The decision confirms that airlines can face liability not just for things that go wrong with the plane itself, but for unreasonable refusals by crew members to accommodate passengers with known medical needs, expanding the practical reach of international air-passenger liability rules.
“an unexpected or unusual event or happening that is external to the passenger”
The Court's core definition of what counts as an 'accident' under the treaty.
How it got here: A federal district court found the airline liable after a bench trial, and the Ninth Circuit affirmed; the airline asked the Supreme Court to review the liability finding.
The Case in Depth
What happened
Dr. Abid Hanson, who had asthma and was sensitive to secondhand smoke, was seated near the smoking section on an Olympic Airways flight from Athens to San Francisco despite requesting a nonsmoking seat. A flight attendant refused three times to move him, saying the plane was full. Cigarette smoke aggravated his asthma during the flight, and he died after suffering a severe reaction despite emergency treatment from fellow passengers.
The question before the Court
When a flight attendant refuses three times to move an asthmatic passenger away from cigarette smoke and he later dies, does that refusal count as an "accident" making the airline liable under international law?
The Court's answer
Yes — the Court ruled that the flight attendant's repeated, unusual refusal to move Dr. Hanson away from cigarette smoke could count as an 'accident' under Article 17 of the Warsaw Convention, even though her conduct was a failure to act rather than something she affirmatively did. The Court explained that any injury results from a chain of causes, and a plaintiff need only show that one link in that chain was an unexpected, unusual event external to the passenger — it doesn't have to be the single event that directly produced the injury.
The Court rejected the airline's argument that only the ordinary presence of cabin smoke mattered, and rejected the claim that inaction can never qualify as an 'accident.' Because the airline had already conceded the attendant's refusal was unusual under its own policies and industry standards, the Court held that refusal was enough to establish liability, and it upheld the lower courts' rulings against the airline.

Why it matters
Airlines flying international routes now have clearer exposure to liability when crew members ignore reasonable requests to protect a passenger's health, even if the crew member merely fails to act rather than doing something affirmatively wrong. Passengers with medical conditions gain a stronger basis to hold airlines accountable when flight staff dismiss their safety requests.
What changes now
This is a final merits decision resolving the liability question under the Warsaw Convention. The Ninth Circuit's judgment finding the airline liable is affirmed, so the case does not return to the lower courts for further fact-finding on this issue. The ruling stands as binding precedent for how courts apply the 'accident' requirement to airline crew conduct, including failures to act, in international air travel cases.
What this does not decide
The Court did not decide whether every failure by airline staff to assist a passenger qualifies as an 'accident' — it relied on the airline's concession that the flight attendant's refusal was unusual and unexpected under industry and company standards, and did not need to independently resolve that question.
Concurrences and dissents
Dissent — Justice Scalia
“I cannot see, however, how inaction itself can ever properly be described as an accident. It is not an event; it is a non-event.”The dissent's central objection, quoting an English appellate court, that inaction cannot be an accident.
Justice Scalia argued the Court should have given serious weight to contrary decisions from English and Australian appellate courts holding that mere inaction cannot be an 'accident' under the Warsaw Convention. He contended the flight attendant's in-flight refusal was pure inaction, not action, and that any earlier insistence she remain seated before takeoff was not a proximate cause of death. He would have remanded to let the district court consider whether the attendant's false statement that the plane was full, rather than the refusal itself, caused the death.
How the Court got there
The legal reasoning, step by step
- The Court applied the definition of 'accident' from its earlier decision in Air France v. Saks: an unexpected or unusual event or happening that is external to the passenger, as opposed to the passenger's own internal reaction to a normal flight condition.
- Because any injury is typically the product of a chain of causes, the Court explained that a plaintiff only needs to show that some link in that chain was unusual or unexpected and external to the passenger — not that the entire injury-producing sequence was itself unusual.
- The Court rejected the airline's argument that the analysis should focus solely on the presence of ordinary cigarette smoke in the cabin, since that approach ignored the flight attendant's repeated refusals to reseat the passenger as a separate contributing event in the causal chain.
- The Court also rejected the airline's claim that only affirmative acts, not failures to act, can qualify as an 'accident,' reasoning that the ordinary meaning of 'event' or 'happening' includes a flight attendant's explicit rejection of a specific request for help, and that other Convention provisions treat action and inaction alike for liability purposes.
- Applying this standard, the Court concluded that the flight attendant's unusual and unexpected refusal to move the passenger was a link in the chain of causation leading to his death, satisfying the 'accident' requirement under Article 17.
