Opinion for the Court filed by Circuit Judge TATEL.
Undеr the Foreign Sovereign Immunities Act, foreign states enjoy immunity from suit in federal court unless the plaintiffs claim falls within one of several enu *290 merated exceptions. This case involves the “commercial activity” exception, which applies to any action “based upon a commercial activity carried on in the United States by the foreign state.” 28 U.S.C. § 1605(a)(2). Appellee, an American citizen who injured her foot in a Paris airport, argues that her negligence suit against Air France fits within this exception becаuse the airline’s duty of care arose from her purchase of a plane ticket in the United States. The district court agreed. Because we find the ticket sale necessary to establish Kirkham’s claim and thus sufficient to trigger the commercial activity еxception, we affirm.
I.
In 2000, appellee, Elisabeth Kirkham, purchased airline tickets through a Washington, D.C. travel agency for a trip from the United States to Paris and then on to Bastía. As scheduled, Kirkham took a United Airlines flight to Paris and then, four days later, went to Orly Airpоrt for her Air France flight to Bastía. Placing her bags on a luggage cart, she asked for directions to her gate. After receiving conflicting information from several airport employees, Kirkham approached a blue-uniformed man whom she believеd to be an Air France employee. The man examined Kirkham’s plane ticket and offered to take her to her gate. Struggling to keep up as she pushed her luggage cart, Kirkham followed him into a highly congested area, where either a persоn or a luggage cart struck her foot. Kirkham fell to the ground, and the blue-uniformed man called security, which took her to the airport’s medical center. Kirkham then spent nine days in the hospital before returning to the United States in a wheelchair. She has sincе had several foot surgeries and continues to suffer complications from her injury.
Kirkham filed suit in the United States District Court for the District of Columbia against Air France, alleging that the blue-uniformed man worked for the airline and that her injury resulted from his negligence. Air France thеn filed a motion for summary judgment, asserting that because the Republic of France owned a majority of Air France’s shares at the time of Kirk-ham’s injury, the Foreign Sovereign Immunities Act (FSIA) deprived the district court of subject matter jurisdiction. Kirk-ham responded that her claim falls undеr the FSIA’s commercial activity exception, which provides:
A foreign state shall not be immune from the jurisdiction of courts of the United States or of the States in any case ... in which the action is based upon a commercial activity carried on in the United States by the foreign state
28 U.S.C. § 1605(a)(2). According to Kirkham, this exception applies because the ticket sale, which forms the basis of the “duty” element of her claim, occurred in the United States. Specifically, Kirk-ham claimed that the ticket sale estаblished a passenger-carrier relationship, which imposed a duty on Air France to provide Kirkham “safe passage” between Paris and Bastía. Acknowledging it owes a duty of care towards its passengers, Air France nevertheless asserted that because the accident occurred in a public area of the airport before Kirkham checked in for her flight, she was at most a “prospective passenger” at the time of her injury. Given that no duty of care had arisen at that point, Air Francе argued, Kirkham failed to establish any link between her cause of action and the ticket sale, thus rendering the commercial activity exception inapplicable. Air France neither admitted nor denied that the blue-uniformed man was an employee, but referred to him as “un *291 identified” in its statement of uncontested facts.
The district court found, as the airline argued, that “[i]f Air France did not owe plaintiff a duty of care of safe passage at the time of the accident, then plaintiff cannot show that her claim was based on Air France’s commerсial activity.”
Kirkham v. Société Air France,
No. 03-1083, slip op. at 10,
Air France now appeals, arguing that the district court erred in (1) relying on Kirkham’s speculation that the blue-uniformed man worked for Air France, and (2) finding that if the blue-uniformed man was in fact an Air France employee, Air France owed Kirkham a duty of care at the time of her injury.
II.
We start by noting that Air France raised sovereign immunity through a Rule 56 motion for summary judgment.
See
Fed.R.Civ.P. 56(e). Summary judgment, however, represents a decision on the merits, which courts may render only after jurisdiction has been established.
See, e.g., Winslow v. Walters,
That established, we have jurisdiction to hear Air France’s interlocutory appeal under the collateral order doctrine.
See El-Hadad v. United Arab Emirates,
The sole question before us is whether Kirkham’s negligence claim is “based upon” her ticket purchase within
*292
the meaning of the FSIA’s commercial activity exception. Interpreting this exception, the Supreme Court held in
Saudi Arabia v. Nelson,
Nelson makes clear that the commercial activity exception has no applicаbility where the alleged commercial activity is unnecessary to the plaintiffs claim. As the Court explained, even if the employee’s allegations about the hospital’s recruiting efforts proved true, those facts did nothing to further his intentional tort claims. In оther words, because the employee had no need to demonstrate the hospital recruited him in order to prevail on the merits, the hospital’s recruiting activities provided no basis for his suit. This case is very different. Because, as Air France concedes, Kirkham must show she purchased a plane ticket in order to establish a passenger-carrier relationship with the airline, Oral Arg. at 5:40, 22:25, the ticket sale is necessary to the “duty of care” element of her negligence claim.
Of course, Kirkham’s purchase of the ticket is not
sufficient
to establish that element, for she must also demonstrate that she had acquired passenger status at the time of her injury. For this reason, the district court treated the blue-uniformed man’s employment status and the extent of his control over Kirkham as jurisdictional facts: Without sufficient evidence that the blue-uniformed man had “initiate[d][the] duty of care” created by the ticket sale, the district court reasoned, Kirkham would be unable to rely on that sale to establish her claim.
Kirkham,
slip op. at 8-10,
Although we agree with the district court that Kirkham cannot prevail on the merits of her claim without first demonstrating that she acquired passenger status prior to her injury, we think that issue irrelevant to the jurisdictional question before us. Under the commercial activity exception as interpreted by
Nelson,
we must determine whether the ticket sale is one of “those elements of a claim that, if proven, would entitle [Kirkham] to relief under [her] theory of the case.”
Again, we agree that Kirkham will lose if she fails to show that Air France owed her a duty of care at the time of the accident. But she will also lose if she fails to show that the blue-uniformed man acted negligently or that his negligence proximately caused her injury. The problem with the district court’s approach is that it ties sovereign immunity to the merits of the plaintiffs claim, expanding the category of jurisdictional facts to include aсtions and events other than the actual commercial activity which triggers the exception. Nothing in Nelson suggests such an expansive overlap between the question of sovereign immunity and the substance of the plaintiffs claim.
Equally important, the FSIA gives no indication that the exception’s applicability depends on any aspect of the plaintiffs claim other than the defendant’s commercial activity in the United States. Although the legislative history is “relatively sparse,”
Nelson,
Accordingly, Kirkham’s uncontested ticket purchase is the only jurisdictional fact in this case. Bеcause Air France concedes the ticket sale constituted a commercial activity in the United States, and because Kirkham must establish that sale in order to prevail on the merits, the commercial activity exception applies. We therefore affirm the district court’s finding of subject matter jurisdiction under the FSIA.
So ordered.
