Apache Bohai Corporation, LDC (“Apache Bohai”) appeals an order staying proceedings in the district court and compelling arbitration of its dispute with Texa-eo China, B.V. (“Texaco”). Because this court’s jurisdiction is contested, Apache Bohai filed a conditional petition for writ of mandamus directing the district court to vacate its order and enter an appealable final judgment. Concluding that we lack jurisdiction, we dismiss the appeal. Finding no abuse of discretion, we deny mandamus relief.
I.
On April 2, 1998, Texaco entered into two written farmin agreements1 with Apache China Corporation (“Apache China”), according to which Apache China agreed to drill and pay for three wells on two of Texaco’s acreage blocks in the Bo-hai Bay area of the People’s Republic of China. In December 1998, Apache China assigned its interests in the farmin agreements to Apache Bohai, its affiliate. By June 1999, however, Apache Bohai lost interest in the project and sent documents re-assigning all of its interests under the agreement to Texaco. Texaco signed and returned the relevant documents in January 2000.
These events gave rise to a dispute over the parties’ respective obligations under the contract, and in January 2001, Texaco initiated an arbitration proceeding against Apache China. Apache Bohai was not named in the arbitration proceeding but took action anyway, filing suit in Texas state court requesting a declaratory judgment that the dispute was not arbitrable and that it had no liability to Texaco. Texaco removed the state court proceeding to federal district court and moved to dismiss or stay the litigation and to compel arbitration. The district court granted both motions, issuing an order to compel *309arbitration and choosing to stay rather than dismiss the litigation.

Section 16 of the Federal Arbitration Act (“FAA”), 9 U.S.C. § 16, governs appellate review of arbitration orders. Congress’s intent in enacting § 16 was to favor arbitration,2 and it did so by authorizing immediate appeals from orders disfavoring arbitration and forbidding immediate appeals from orders favoring arbitration. Adams v. Ga. Gulf Corp., 237 F.3d 538, 540 (5th Cir.2001) (citing Forsythe Int’l, S.A. v. Gibbs Oil Co., 915 F.2d 1017, 1020 (5th Cir.1990)). The provisions relevant to this dispute vest the courts of appeals with jurisdiction over “final decision[s] with respect to an arbitration ...,” § 16(a)(3), while specifically denying appellate jurisdiction over nonfinal orders staying proceedings pending arbitration, § 16(b)(1). Therefore, our jurisdiction turns on whether the district court’s order constitutes a final decision.
A final decision is one that “ends the litigation on the merits and leaves nothing more for the court to do but execute the judgment.” Green Tree Fin. Corp.-Alabama v. Randolph, 531 U.S. 79, 86, 121 S.Ct. 513, 148 L.Ed.2d 373 (2000) (citations and internal quotation marks omitted). Under this definition, a dismissal is a final decision. Id. at 89, 121 S.Ct. 513. The district court, however, did not dismiss the claims, but entered a stay pending arbitration. An arbitration order entering a stay, as opposed to a dismissal, is not an appealable final order.3
Apache Bohai contends that when a district court enters an order staying an action and referring all disputed matters to arbitration, leaving no live issues before the district court, this court should consider the order to be, in effect, a de facto dismissal and thus a final decision appeal-able under § 16(a)(3). Unlike a dismissal, however, a stay, by definition, constitutes a postponement of proceedings, not a termination, and thus lacks finality. Further, as other courts have noted, entry of a stay rather than a dismissal “suggests that the district court perceives that it might have more to do than execute the judgment once arbitration has been completed.” ATAC Corp. v. Arthur Treacher’s, Inc., 280 F.3d 1091, 1099 (6th Cir.2002). Consequently, although it may be true that in some instances the entry of a stay disposes of most or all issues, that fact alone does not render it the functional equivalent of a dismissal.4
Apache Bohai cites two cases in which we found appellate jurisdiction despite the plain absence of a dismissal; neither contradicts our conclusion that a stay is not a *310final decision. In Am. Heritage Life Ins. Co. v. Orr, 294 F.3d 702 (5th Cir.2002), we held that an order compelling arbitration and “closing” the case was a renewable final decision.5 The district court in that case had issued an order staying state court proceedings, compelling arbitration, and closing the case, leaving nothing to do but execute the judgment. Id. In that context, we held that “closing” the case was functionally indistinguishable from dismissal.6 In this case, by contrast, the court did not purport to close the case administratively, nor did it attempt in any other way to terminate its involvement in the proceedings.
Apache Bohai also cites Gulf Guar. Life Ins. Co. v. Conn. Gen. Life Ins. Co., 304 F.3d 476 (5th Cir.2002), as an example of this court’s willingness to find the existence of an appealable final decision despite the lack of an explicit dismissal. In Gulf Guaranty, id. at 480-81, the district court reopened a suit for the express purpose of consolidating it with a later action. The order forming the basis for the appeal in Gulf Guaranty explicitly dismissed the later action but failed to mention the claims from the earlier suit. Id. We concluded, in light of the various indications that the court intended to dismiss both suits, that the order was a final decision.
Far from expanding the definition of final decision for purposes of § 16(a)(3), we merely recognized that “the intention, as well as the effect [of the order], was to dismiss [the action].” Id. at 483.7 Here, there is no indication that the district court intended to dismiss the case but failed to do so through an oversight. Rather, it entered an order expressly granting a stay of the proceedings pending arbitration.
III.
In the alternative, Apache Bohai seeks a writ of mandamus directing the district court to vacate its order and enter an appealable final judgment. Mandamus is a drastic remedy reserved only for truly extraordinary situations. Will v. United States, 389 U.S. 90, 106, 88 S.Ct. 269, 19 L.Ed.2d 305 (1967). The district court must have committed a “clear abuse of discretion” or engaged in “conduct amounting to the usurpation of power.” Mallard v. United States Dist. Ct. for the Southern Dist. of Iowa, 490 U.S. 296, 309, 109 S.Ct. 1814, 104 L.Ed.2d 318 (1989) (citations and internal quotation marks omitted). This burden is particularly heavy in the context of mandamus review of a decision to enter a stay pending arbitration, “because Congress has expressly limited interlocutory review of a district court decision on arbitration.” McDermott Int% Inc. v. Underwriters at Lloyds, 981 F.2d 744, 748 (5th Cir.1993). “Moreover, it is more than well settled that a writ of mandamus is not to be used as a substitute for appeal[.]” Id.
To establish its entitlement to mandamus relief, Apache Bohai is required to show clearly and indisputably that the district court did not have the discretion to stay the proceedings pending arbitration.8 *311It has not made this showing. Apache Bohai is unable to cite a single case in which we held that a district court abused its discretion by staying rather than dismissing proceedings pending arbitration.9 Indeed, we have held that a decision, under similar circumstances, to issue a stay rather than a dismissal was not an abuse of discretion warranting mandamus.10
The appeal in No. 02-20489 is DISMISSED, and the petition for writ of mandamus in No. 02-21158 is DENIED.
