This action is brought pursuant to Article 17 of the Convention for the Unification of Certain Rules Relating to International Transportation by Air, Oct. 12, 1929, art. 17, 49 Stat. 3000, T.S. No. 876 (1934), reprinted in note following 49 U.S.C. § 40105 (“Warsaw Convention” or “Convention”). The parties agree, and we concur, that this action is governed exclusively by the Warsaw Convention. The scope of our review is limited to whether appellant Guy Caman (“Caman”) can establish liability against appellee Continental Airlines (“Continental”) under the Convention. 1 We hold that the district court properly granted summary judgment in *1089 favor of Continental on the ground that Continental’s failure to warn Caman of the possibility of developing Deep Vein Thrombosis (“DVT”) during the course of an international flight does not constitute an “accident” under the Warsaw Convention. Accordingly, we affirm.
BACKGROUND
Caman alleges that he developed DVT while on board an international flight operated by Continental. Caman’s axial argument is that Continental’s failure to advise him of the risk of DVT, which can result from immobility, dehydration and being cramped in a small pitch seat over the course of an international flight, constitutes an “accident” for purposes of establishing liability under the Warsaw Convention.
The following facts are uncontested. On May 28, 2002, Caman departed from Los Angeles, California, on a flight bound for Paris, France. The flight was uneventful with no equipment malfunction or other anomaly occurring. Caman did not receive any warning regarding the potential hazard of developing DVT on his international flight. During the course of his air travel, up to and including his disembarkation from the aircraft, Caman did not request any assistance or other accommodation from Continental personnel. Upon his arrival in France, Caman found it difficult to walk on his right leg and immediately sought medical attention. He was diagnosed with DVT and was admitted to a hospital where he remained for three days. He received therapy amounting to injections several times a week for the next month.
STANDARD OF REVIEW
Caman appeals the district court’s grant of summary judgment in favor of Continental. We review the district court’s grant of summary judgment de novo.
Carey v. United Airlines, 255
F.3d 1044, 1047 (9th Cir.2001). Interpretations of treaties, such as the Warsaw Convention, are questions of law that are also reviewed de novo.
Hosaka v. United Airlines, Inc.,
ANALYSIS
Caman seeks review of the lower court’s ruling that an air carrier’s failure to warn passengers of the risk of developing DVT during international air travel is not an “accident” for purposes of Article 17 liability. Article 17 of the Warsaw Convention imposes liability on an air carrier for a passenger’s death or bodily injury caused by an “accident” that occurred in connection with an international flight.
Olympic Airways v. Husain,
It is well settled that the development of DVT as the result of international air travel, without more, does not constitute an “accident” for purposes of Article 17 liability.
See, e.g., Rodriguez v. Ansett Austl. Ltd.,
I.
The seminal case on the issue of what constitutes an accident under Article 17 of the Warsaw Convention is
Air France v. Saks,
Nearly two decades after
Saks
was decided, the Supreme Court revisited the question of what constitutes an Article 17 “accident.”
Husain,
In
Blansett v. Continental Airlines, Inc.,
The Blansett court carefully abstained from creating a per se rule that any departure from an industry standard constitutes an Article 17 “accident.” Id. at 182. Instead, the court pointed to the absence of any Federal Aviation Administration requirement that warnings of DVT be issued on international flights as evidence that a failure to warn of DVT is not “unexpected” and, therefore, outside the scope of Article 17. As the court explained in summation, “[i]t was not an unexpected or unusual decision for Continental merely to cleave to the exclusive list of warnings required of it by the agency that has regulatory jurisdiction over its flights.” Id.
In
Rodriguez
this court addressed circumstances very similar to those presented here. Specifically, we considered first whether developing DVT can constitute an Article 17 “accident,” and second, whether a failure to warn of the risk of DVT can constitute an Article 17 “accident.”
The foregoing decisions have left unresolved certain issues salient to this court’s inquiry. Specifically, whether an air carrier’s departure from either industry standard or its own company policy are the appropriate benchmark for determining whether an event is “unexpected or unusual” conduct under Article 17 4 and, more importantly, whether the inaction alleged here is sufficient to constitute an Article 17 “event.”
II.
The starting point of our analysis is, of course, the text of the Convention and the context in which the written words are used.
Saks,
The carrier shall be liable for damage sustained in the event of the death or wounding of a passenger or any other bodily injury suffered by a passenger, if the accident which caused the damage so sustained took place on board the aircraft or in the course of any of the operations of embarking or disembarking.
Art. 17, 49 Stat. 3018. The foregoing language clearly establishes the liability of international air carriers for accidents resulting in harm to passengers sustained during any operations of the aircraft. Conversely, Article 20(1) provides a defense for air carriers. The language of Article 20(1) is as follows:
*1092 The carrier shall not be liable if he proves that he and his agents have taken all necessary measures to avoid the damage or that it was impossible for him or them to take such measures.
Art. 20, 49 Stat. 3019.
With respect to considering these two Articles, the Supreme Court explained that “[t]he ‘accident’ requirement of Article 17 is distinct from the defenses in Article 20(1), both because it is located in a separate article and because it involves an inquiry into the nature of the event which
caused
the injury rather than the care taken by the airline to avert the injury.”
Saks,
Applying the treaty’s text and Supreme Court precedent to the facts of this case, we hold that Caman cannot establish his DVT was the result of an “accident” because he cannot show that it resulted from an “unexpected or unusual event.”
Saks,
For the foregoing reasons, we conclude that Continental’s failure to warn Caman of the risk of developing DVT is not an Article 17 “accident.” Accordingly, he cannot obtain relief under the Warsaw Convention.
AFFIRMED.
Notes
. A passenger whose injury is not compensa-ble under the Warsaw Convention because it entails no "bodily injury" or was not the result of an "accident” will have no recourse to an alternate remedy.
El Al Isr. Airlines v. Tseng,
. The Supreme Court's discussion of this issue in
Husain
is as follows: “As an initial matter, we note that petitioner did not challenge in the Court of Appeals the District Court's finding that the flight attendant’s conduct in three times refusing to move [the passenger] was unusual or unexpected in light of the relevant industry standard or petitioner's own company policy.... Consequently, we need not dispositively determine whether the flight attendant’s conduct qualified as 'unusual or unexpected' under
Saks,
but may assume that it was for purposes of this opinion.”
Husain,
. This argument is directly drawn from the
Husain
decision. As noted
supra,
the
Husain
Court expressly declined to decide whether the refusal to assist a passenger was "unexpected."
See
n. 2,
supra.
Rather, the Court adopted the district court's reasoning that the departure from industry standard made the air crew’s conduct "unexpected."
Husain,
. We recognize that there are questions as to whether an air carrier’s departure from an industry standard or its own company policy is "unexpected” for the purpose of defining an Article 17 "accident.” We decline to address this question as our holding today does not turn on the resolution of that issue.
