Justice Ginsburg
delivered the opinion of the Court.
Plaintiff-respondent Tsui Yuan Tseng was subjected to an intrusive security search at John P. Kennedy International Airport in New York before she boarded an El A1 Israel Airlines May 22, 1993 flight to Tel Aviv. Tseng seeks tort damages from El A1 for this occurrence. The episode-in-suit, both parties now submit, does not qualify as an “accident” within the meaning of the treaty popularly known as the Warsaw Convention, which governs air carrier liability for “all international transportation.”1 Tseng alleges psychic or psychosomatic injuries, but no “bodily injury,” as that term is used in the Convention. Her case presents a question of the Convention’s exclusivity: When the Convention allows no recovery for the episode-in-suit, does it correspondingly preclude the passenger from maintaining an action for damages under another source of law, in this case, New York tort law?
The exclusivity question before us has been settled prospectively in a Warsaw Convention protocol (Montreal Protocol No. 4) recently ratified by the Senate.2 In accord with the protocol, Tseng concedes, a passenger whose injury is not compensable under the Convention (because it entails no “bodily injury” or was not the result of an “accident”) will [161]*161have no recourse to an alternate remedy. We conclude that the protocol, to which the United States has now subscribed, clarifies, but does not change, the Convention’s exclusivity domain. We therefore hold that recovery for a personal injury suffered “on board [an] aircraft or in the course of any of the operations of embarking or disembarking,” Art. 17, 49 Stat. 3018, if not allowed under the Convention, is not available at all.
The Court of Appeals for the Second Circuit ruled otherwise. In that court’s view, a plaintiff who did not qualify for relief under the Convention could seek relief under local law for an injury sustained in the course of international air travel. 122 F. 3d 99 (1997). We granted certiorari, 523 U. S. 1117 (1998),3 and now reverse the Second Circuit’s judgment. Recourse to local law, we are persuaded, would undermine the uniform regulation of international air carrier liability that the Warsaw Convention was designed to foster.

We have twice reserved decision on the Convention’s exclusivity. In Air France v. Saks, 470 U. S. 392 (1985), we concluded that a passenger’s injury was not caused by an “accident” for which the airline could be held accountable under the Convention, but expressed no view whether that passenger could maintain “a state cause of action for negli[162]*162gence.” Id., at 408. In Eastern Airlines, Inc. v. Floyd, 499 U. S. 530 (1991), we held that mental or psychic injuries unaccompanied by physical injuries are not compensable under Article 17 of the Convention, but declined to reach the question whether the Convention “provides the exclusive cause of action for injuries sustained during international air transportation.” Id., at 558. We resolve in this case the question on which we earlier reserved judgment. the
At the outset, we highlight key provisions of the treaty we are interpreting. Chapter I of the Warsaw Convention, entitled “Scope — DEFINITIONS,” declares in Article 1(1) that the “[Cjonvention shall apply to all international transportation of persons, baggage, or goods performed by aircraft for hire.” 49 Stat. 3014.4 Chapter III, entitled “Liability op the Carrier,” defines in Articles 17, 18, and 19 the three kinds of liability for which the Convention provides. Article 17 establishes the conditions of liability for personal injury to passengers:
“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.” 49 Stat. 3018.
Article 18 establishes the conditions of liability for damage to baggage or goods. Id., at 3019.5 Article 19 establishes [163]*163the conditions of liability for damage caused by delay. Ibid.6 Article 24, referring back to Articles 17,18, and 19, instructs:
eases covered by articles 18 and 19 any action for damages, however founded, can only be brought subject to the conditions and limits set out in this convention.
“(2) In the eases covered by article 17 the provisions of the preceding paragraph shall also apply, without prejudice to the questions as to who are the persons who have the right to bring suit and what are their respective rights.” Id., at 3020.7
i
With the key treaty provisions as the backdrop, we next describe the episode-in-suit. On May 22, 1993, Tsui Yuan Tseng arrived at John F. Kennedy International Airport (hereinafter JFK) to board an El A1 Israel Airlines flight to Tel Aviv. In conformity with standard El A1 preboarding procedures, a security guard questioned Tseng about her destination and travel plans. The guard considered Tseng’s responses “illogical,” and ranked her as a “high risk” passenger. Tseng was taken to a private security room where her baggage and person were searched for explosives and detonating devices. She was told to remove her shoes, jacket, and sweater, and to lower her blue jeans to mid-[164]*164hip. A female security guard then searched Tseng’s body outside her clothes by hand and with an electronic security wand.
After the search, which lasted 15 minutes, El A1 personnel decided that Tseng did not pose a security threat and allowed her to board the flight. Tseng later testified that she “was really sick and very upset” during the flight, that she was “emotionally traumatized and disturbed” during her month-long trip in Israel, and that, upon her return, she underwent medical and psychiatric treatment for the lingering effects of the body search. 122 F. 3d 99, 101 (CA2 1997) (internal quotation marks omitted).
Tseng filed suit against El A1 in 1994 in a New York state court of first instance. Her complaint alleged a state-law personal injury claim based on the May 22, 1993 episode at JFK. Tseng’s pleading charged, inter alia, assault and false imprisonment, but alleged no bodily injury. El A1 removed the case to federal court.
The District Court, after a bench trial, dismissed Tseng’s personal injury claim. See 919 F. Supp. 155 (SDNY 1996). That claim, the court concluded, was governed by Article 17 of the Warsaw Convention, which creates a cause of action for personal injuries suffered as a result of an “accident... in the course of any of the operations of embarking or disembarking,” 49 Stat. 3018. See 919 F. Supp., at 157-158. Tseng’s claim was not compensable under Article 17, the District Court stated, because Tseng “sustained no bodily injury” as a result of the search, id., at 158, and the Convention does not permit “recovery for psychic or psychosomatic injury unaccompanied by bodily injury,” ibid, (citing Floyd, 499 U. S., at 552). The District Court further concluded that Tseng could not pursue her claim, alternately, under New York tort law; as that court read the Convention, Article 24 shields the carrier from liability for personal injuries not compensable under Article 17. See 919 F. Supp., at 158.
[165]*165The Court of Appeals reversed in relevant part. See 122 F. 3d 99 (CA2 1997).8 The Second Circuit concluded first that no “accident” within Article 17’s compass had occurred; in the Court of Appeals’ view, the Convention drafters did not “ai[m) to impose close to absolute liability” for an individual’s “personal reaction” to “routine operating procedures,” measures that, although “ineonvenien[t] and embarass[ing],” are the “price passengers pay for ... airline safety.” Id., at 103-104.9 In some tension with that reasoning, the Second [166]*166Circuit next concluded that the Convention does not shield the very same “routine operating procedures” from assessment under the diverse laws of signatory nations (and, in the ease of the United States, States within one Nation) governing assault and false imprisonment. See id., at 104.
Article 24 of the Convention, the Court of Appeals said, “clearly states that resort to local law is precluded only where the incident is ‘covered’ by Article 17, meaning where there has been an accident, either on the plane or in the course of embarking or disembarking, which led to death, wounding or other bodily injury.” Id., at 104-105. The court found support in the drafting history of the Convention, which it construed to “indicate that national law was intended to provide the passenger’s remedy where the Convention did not expressly apply.” Id., at 105. The Second Circuit also rejected the argument that allowance of state-law claims when the Convention does not permit recovery would contravene the treaty’s goal of uniformity. The court read our decision in Zicherman v. Korean Air Lines Co., 516 U. S. 217 (1996), to “instruct specifically that the Convention expresses no compelling interest in uniformity that would warrant . . . supplanting an otherwise applicable body of law.” 122 F. 3d, at 107.

We accept it as given that El Al’s search of Tseng was not an “accident” within the meaning of Article 17, for the parties do not place that Court of Appeals conclusion at issue. See supra, at 165 and this page, n. 9. We also accept, again only for purposes of this decision, that El Al’s actions did not constitute “wilful misconduct”; accordingly, we confront no issue under Article 25 of the Convention, see supra, at 163, [167]*167n. 7.10 The parties do not dispute that the episode-in-suit occurred in international transportation in the course of embarking.
Our inquiry begins with the text of Article 24, which prescribes the exclusivity of the Convention’s provisions for air carrier liability. “[I]t is our responsibility to give the specific words of the treaty a meaning consistent with the shared expectations of the contracting parties.” Saks, 470 U. S., at 399. “Because a treaty ratified by the United States is not only the law of this land, see U. S. Const., Art. II, §2, but also an agreement among sovereign powers, we have traditionally considered as aids to its interpretation the negotiating and drafting history (travaux préparatoires) and the postratification understanding of the contracting parties.” Zicherman, 516 U. S., at 226.
Article 24 provides that “eases covered by article 17” — or in the governing French text, “les cas prévus á (’article 17”11 — may “only be brought subject to the conditions and [168]*168limits set out in th[e] [Convention.” 49 Stat. 3020. That prescription is not a model of the clear drafter’s art. We recognize that the words lend themselves to divergent interpretation.
In Tseng’s view, and in the view of the Court of Appeals, “les cas prévus á l’article 17” means those cases in which a passenger could actually maintain a claim for relief under Article 17. So read, Article 24 would permit any passenger whose personal injury suit did not satisfy the liability conditions of Article 17 to pursue the claim under local law.
In El Al’s view, on the other hand, and in the view of the United States as amicus curiae, “les cas prévus á l’article 17” refers generically to all personal injury eases stemming from occurrences on board an aircraft or in embarking or disembarking, and simply distinguishes that class of cases (Article 17 cases) from cases involving damaged luggage or goods, or delay (which Articles 18 and 19 address). So read, Article 24 would preclude a passenger from asserting any air transit personal injury claims under local law, including claims that failed to satisfy Article 17’s liability conditions, notably, because the injury did not result from an “accident,” see Saks, 470 U. S., at 405, or because the “accident” did not result in physical injury or physical manifestation of injury, see Floyd, 499 U. S., at 552.
Respect is ordinarily due the reasonable views of the Executive Branch concerning the meaning of an international treaty. See Sumitomo Shoji America, Inc. v. Avagliano, 457 U. S. 176, 184-185 (1982) (“Although not conclusive, the meaning attributed to treaty provisions by the Government agencies charged with their negotiation and enforcement is entitled to great weight.”). We conclude that the Govern[169]*169ment’s construction of Article 24 is most faithful to the Convention’s text, purpose, and overall structure.
A
The cardinal purpose of the Warsaw Convention, we have observed, is to “achiev[e] uniformity of rules governing claims arising from international air transportation.” Floyd, 499 U. S., at 552; see Zicherman, 516 U. S., at 230. The Convention signatories, in the treaty’s preamble, specifically "recognized the advantage of regulating in a uniform manner the conditions of... the liability of the carrier.” 49 Stat. 3014. To provide the desired uniformity, Chapter III of the Convention sets out an array of liability rules which, the treaty declares, "apply to all international transportation of persons, baggage, or goods performed by aircraft.” Ibid. In that Chapter, the Convention describes and defines the three areas of air carrier liability (personal injuries in Article 17, baggage or goods loss, destruction, or damage in Article 18, and damage occasioned by delay in Article 19), the conditions exempting air carriers from liability (Article 20), the monetary limits of liability (Article 22), and the circumstances in which air carriers may not limit liability (Articles 23 and 25). See supra, at 162-163, and n. 7. Given the Convention’s comprehensive scheme of liability rules and its textual emphasis on uniformity, we would be hard put to conclude that the delegates at Warsaw meant to subject air carriers to the distinct, nonuniform liability rules of the individual signatory nations.
The Court of Appeals looked to our precedent for guidance on this point, but it mispereeived our meaning. It misread our decision in Zicherman to say that the Warsaw Convention expresses no compelling interest in uniformity that would warrant preempting an otherwise applicable body of law, here New York tort law. See 122 F. 3d, at 107; supra, at 166. Zicherman acknowledges that the Convention een-[170]*170trally endeavors “to foster uniformity in the law of international air travel.” 516 U. S., at 230. It further recognizes that the Convention addresses the question whether there is airline liability vel non. See id., at 231. The Zicherman case itself involved auxiliary issues: who may seek recovery in lieu of passengers, and for what harms they may be compensated. See id., at 221,227. Looking to the Convention’s text, negotiating and drafting history, contracting states’ postratification understanding of the Convention, and scholarly commentary, the Court in Zicherman determined that Warsaw drafters intended to resolve whether there is liability, but to leave to domestic law (the local law identified by the forum under its choice-of-law rules or approaches) determination of the compensatory damages available to the suitor. See id., at 231.
A complementary purpose of the Convention is to accommodate or balance the interests of passengers seeking recovery for personal injuries, and the interests of air carriers seeking to limit potential liability. Before the Warsaw accord, injured passengers could file suits for damages, subject only to the limitations of the forum’s laws, including the forum’s choice-of-law regime. This exposure inhibited the growth of the then-fledgling international airline industry. See Floyd, 499 U. S., at 546; Lowenfeld & Mendelsohn, The United States and the Warsaw Convention, 80 Harv. L. Rev. 497, 499-500 (1967). Many international air carriers at that time endeavored to require passengers, as a condition of air travel, to relieve or reduce the carrier’s liability in case of injury. See Second International Conference on Private Aeronautical Law, October 4-12, 1929, Warsaw, Minutes 47 (R. Horner & D. Legrez transís. 1975) (hereinafter Minutes). The Convention drafters designed Articles 17, 22, and 24 of the Convention as a compromise between the interests of air carriers and their customers worldwide. In Article 17 of the Convention, carriers are denied the contractual prerogative to exclude or limit their liability for personal injury. In [171]*171Articles 22 and 24, passengers are limited in the amount of damages they may recover, and are restricted in the claims they may pursue by the conditions and limits set out in the Convention.
Construing the Convention, as did the Court of Appeals, to allow passengers to pursue claims under local law when the Convention does not permit recovery could produce several anomalies. Carriers might be exposed to unlimited liability under diverse legal regimes, but would be prevented, under the treaty, from contracting out of such liability. Passengers injured physically in an emergency landing might be subject to the liability caps of the Convention, while those merely traumatized in the same mishap would be free to sue outside of the Convention for potentially unlimited damages. The Court of Appeals’ construction of the Convention would encourage artful pleading by plaintiffs seeking to opt out of the Convention’s liability scheme when local law promised recovery in excess of that prescribed by the treaty. See Potter v. Delta Air Lines, Inc., 98 F. 3d 881, 886 (CA5 1996). Such a reading would scarcely advance the predictability that adherence to the treaty has achieved worldwide.12
The Second Circuit feared that if Article 17 were read to exclude relief outside the Convention for Tseng, then a passenger injured by a malfunctioning escalator in the airline’s terminal would have no recourse against the airline, even if the airline recklessly disregarded its duty to keep the escalator in proper repair. See 122 F. 3d, at 107. As the United States pointed out in its amicus curiae submission, however, the Convention addresses and concerns, only and exclusively, [172]*172the airline’s liability for passenger injuries occurring “on board the aircraft or in the course of any of the operations of embarking or disembarking.” Art. 17, 49 Stat. 3018; see Brief for United States as Amicus Curiae 16. “[T]he Convention’s preemptive effect on local law extends no further than the Convention’s own substantive scope.” Ibid. A carrier, therefore, “is indisputably subject to liability under local law for injuries arising outside of that scope: e. g., for passenger injuries occurring before ‘any of the operations of embarking’” or disembarking. Ibid, (quoting Article 17).
Tseng raises a different concern. She argues that air carriers will escape liability for their intentional torts if passengers are not permitted to pursue personal injury claims outside of the terms of the Convention. See Brief for Respondent 15-16. But we have already cautioned that the definition of “accident” under Article 17 is an “unusual event . . . external to the passenger,” and that “[tjhis definition should be flexibly applied.” Saks, 470 U. S., at 405 (emphasis added). In Saks, the Court concluded that no “accident” occurred because the injury there — a hearing loss — “indisputably resulted] from the passenger’s own internal reaction to the usual, normal, and expected operation of the aircraft.” Id., at 406 (emphasis added). As we earlier noted, see supra, at 165-166, n. 9, Tseng and El A1 chose not to pursue in this Court the question whether an “accident” occurred, for an affirmative answer would still leave Tseng unable to recover under the treaty; she sustained no “bodily injury” and could not gain compensation under Article 17 for her solely psychic or psychosomatic injuries.
B
The drafting history of Article 17 is consistent with our understanding of the preemptive effect of the Convention. The preliminary draft of the Convention submitted to the conference at Warsaw made air carriers liable “in the ease of death, wounding, or any other bodily injury suffered by a [173]*173traveler.” Minutes 264; see Saks, 470 U. S., at 401. In the later draft that prescribed what is now Article 17, airline liability was narrowed to encompass only bodily injury caused by an “accident.” See Minutes 205. It is improbable that, at the same time the drafters narrowed the conditions of air carrier liability in Article 17, they intended, in Article 24, to permit passengers to skirt those conditions by pursuing claims under local law.13
Inspecting the drafting history, the Court of Appeals stressed a proposal made by the Czechoslovak delegation to state in the treaty that, in the absence of a stipulation in the Convention itself, “'the provisions of laws and national rules relative to carriage in each [signatory] State shall apply.’” 122 F. 3d, at 105 (quoting Minutes 176). That proposal was withdrawn upon amendment of the Convention’s title to read: “Convention For The Unification Of Certain Rules Relating To International Transportation By Air.” 49 Stat. 3014 (emphasis added); see 122 F. 3d, at 105. The Second Circuit saw in this history an indication “that national law was intended to provide the passenger’s remedy where the Convention did not expressly apply.” 122 F. 3d, at 105.
The British House of Lords, in Sidhu v. British Airways plc, [1997] 1 All E. R. 193, considered the same history, but found it inconclusive. Inclusion of the word “certain” in the Convention’s title, the Lords reasoned, accurately indicated that “the [Convention is concerned with certain rules only, not with all the rules relating to international carriage by air.” Id., at 204. For example, the Convention does not say “anything . . . about the carrier’s obligations of insurance, and in particular about compulsory insurance against third party risks.” Ibid. The Convention, in other words, is “a [174]*174partial harmonisation, directed to the particular issues with which it deals,” ibid., among them, a carrier’s liability to passengers for personal injury. As to those issues, the Lords concluded, “the aim of the [Cjonvention is to unify.” Ibid. Pointing to the overall understanding that the Convention’s objective was to “ensure uniformity,” id., at 209, the Lords suggested that the Czechoslovak delegation may have meant only to underscore that national law controlled “chapters of law relating to international carriage by air with which the [Cjonvention was not attempting to deal.” Ibid. In light of the Lords’ exposition, we are satisfied that the withdrawn Czechoslovak proposal will hot bear the weight the Court of Appeals placed on it.
C
Montreal Protocol No. 4, ratified by the Senate on September 28, 1998,14 amends Article 24 to read, in relevant part: “In the carriage of passengers and baggage, any action for damages, however founded, can only be brought subject to the conditions and limits set out in this Convention ....”15 Both parties agree that, under the amended Article 24, the [175]*175Convention’s preemptive effect is clear: The treaty precludes passengers from bringing actions under local law when they cannot establish air carrier liability under the treaty. Revised Article 24, El A1 urges and we agree, merely clarifies, it does not alter, the Convention’s rule of exclusivity.
Supporting the position that revised Article 24 provides for preemption not earlier established, Tseng urges that federal preemption of state law is disfavored generally, and particularly when matters of health and safety are at stake. See Brief for Respondent 31-33. See also post, at 181 (Stevens, J., dissenting) (“[A] treaty, like an Act of Congress, should not be construed to preempt state law unless its intent to do so is clear.”). Tseng overlooks in this regard that the nation-state, not subdivisions within one nation, is the focus of the Convention and the perspective of our treaty partners. Our home-centered preemption analysis, therefore, should not be applied, mechanically, in construing our international obligations.
Decisions of the courts of other Convention signatories corroborate our understanding of the Convention’s preemptive effect. In Sidhu, the British House of Lords considered and decided the very question we now face concerning the Convention’s exclusivity when a passenger alleges psychological damages, but no physical injury, resulting from an occurrence that is not an “accident” under Article 17. See 1 All E. R., at 201, 207. Reviewing the text, structure, and drafting history of the Convention, the Lords concluded that the Convention was designed to “ensure that, in all questions relating to the carrier’s liability, it is the provisions of the [Convention which apply and that the passenger does not have access to any other remedies, whether under the common law or otherwise, which may be available within the particular country where he chooses to raise his action.” Ibid. Courts of other nations bound by the Convention have also recognized the treaty’s encompassing preemptive ef-[176]*176feet.16 The "opinions of our sister signatories,” we have observed, are “entitled to considerable weight.” Saks, 470 U. S., at 404 (internal quotation marks omitted). The text, drafting history, and underlying purpose of the Convention, in sum, counsel us to adhere to a view of the treaty’s exclusivity shared by our treaty partners.
* * *
For the reasons stated, we hold that the Warsaw Convention precludes a passenger from maintaining an action for personal injury damages under local law when her claim does not satisfy the conditions for liability under the Convention. Accordingly, we reverse the judgment of the Second Circuit.
It is so ordered.
