We consider whether an appeal by an aircraft lessor is moot if the lessor seeks modification of post-petition lenders’ bargained-for collateral but has failed to seek *1194 a stay of the relevant post-petition financing order pursuant to 11 U.S.C. § 364(e). For the reasons set forth below, we conclude that these appeals are moot and dismiss. Solely because of case-specific, equitable considerations, we do not vacate the decisions below.
I
These appeals arise from bankruptcy proceedings regarding Western Pacific Airlines, Inc. (“WestPac”). In appeal No. 98-1018 (“the lease assignment appeal”), Boullioun Aircraft Holding Co. and Boul-lioun Portfolio Finance I, Inc. (“Boullioun”) challenge the bankruptcy court’s December 10, 1997, decision that WestPac could assign its interest in three planes that it leased from Boullioun as collateral to providers of post-petition financing, despite provisions in the leases prohibiting such assignment.

In appeal No. 98-1214 (“the repossession appeal”), Boullioun challenges the district court’s interpretation of another aspect of 11 U.S.C. . § 1110. The district court, in

At the threshold, we consider ap-pelleés’ assertion that these appeals are moot. “We review the issue of mootness de novo.”
Anderson v. United States Dep’t of Health & Human Services,
A
We first address appellees’ mootness claim with respect to appeal No. 98-1018, the lease assignment appeal. The district court concluded that Boullioun’s challenge to the bankruptcy court decision permitting assignment of Boullioun’s leases as collateral for the post-petition financing is moot because of Boullioun’s failure to seek a stay of the financing order pursuant to 11 U.S.C. § .364(e).
See In re Western Pacific Airlines, Inc.,
[t]he reversal or modification on appeal of an authorization under this section to obtain credit or incur debt, or of a grant under this section of a priority or a lien, does not affect the validity of any debt so incurred, or any priority or lien so granted, to an entity that extended such credit in good faith, whether or riot such entity knew of the pendency of the appeal, unless such authorization and the incurring of such debt or the granting of such priority or lien, were stayed pending appeal.
11 NS.C. § 364(e). 2
Although § 364(e) facially provides for the “reversal or modification on appeal” of an authorization to incur debt and the grant of a priority lien, it limits the effect of such modification if the challenging party has failed to seek a stay. Accordingly, § 364(e) renders some financing order challenges effectively moot.
See, e.g., In re Adams Apple, Inc.,
We agree with the conclusion reached in
In. re Clinton Street Food Corp.,
We reject Boullioun’s argument that the reasoning of the Third Circuit’s decision in
In re Swedeland Dev. Group,
We also reject Boullioun’s argument that an unresolved issue regarding a sanction of $4,000 in attorney fees saves this case from mootness.

The $4,000 sanction represents an award of attorney fees to the estate for expenses arising from issues relating to one of three aircraft leases. Precedent clearly indicates that “an interest in attorney’s fees is insufficient to create an Article III case or controversy where a case or controversy does not exist on the merits of the underlying claim.”
Cox v. Phelps Dodge Corp.,
In its reply brief, Boullioun also argues that our resolution of the lease
*1197
assignment issue will have legal consequences in pending bankruptcy court litigation regarding certain tax claims. Although its argument is unclear, Boullioun apparently contends that reversal of the order holding § 1110 inapplicable would shield its security deposits from the property tax claims at issue in the pending adversary proceeding. This possible consequence 'does not save this case from mootness. Potential collateral consequences in a separate adversary proceeding do not obviate our inability, under § 364(e), to fashion meaningful relief on Boullioun’s underlying claim regarding § 1110. The only way to grant Boullioun the relief it seeks in the lease assignment appeal, and thereby the collateral relief it seeks in the tax proceeding, is for us to invalidate the district court’s unstayed decision in the financing order permitting assignment of the leases to Boullioun’s aircraft. This, as stated above, is relief we cannot grant under § 364(e). Boullioun fails to point us to any other provision of the Bankruptcy Code or state law that would permit us to fashion a remedy that would not disturb the validity of the financing and terms of its collateralization.

We turn to appellees’ claim that the repossession appeal, No. 98-1214, is moot. At issue here is the district court’s March 10, 1998, decision that Boullioun was not entitled, pursuant to its lease agreements and 11 U.S.C. § 1110, to repossess its aircraft despite WestPac’s lease default following its' prior cure of defaults and entry into a § 1110(a) agreement.

Having concluded that Boul-lioun’s appeals are moot, we must decide whether to vacate the decisions below. When a case becomes moot while on appeal, we generally vacate the judgment below and remand with a direction to dismiss.
See United States v. Munsingwear, Inc.,
Boullioun urges us to vacate the bankruptcy court’s December 4, 1997 order 8 and the district court’s January 12, 1998 order 9 should we conclude, as we have, *1198 that Boullioun’s assignment appeal, No. 98-1018, is moot. Boullioun argues that vacatur would free it from the preclusive effect of the lower court decisions regarding future assignment of Boullioun’s aircraft leases. Appellees urge us not to vacate the decisions at issue in this appeal, based on their concern that such a decision could create unforseen problems by complicating repayment issues, and could undermine actions taken in reliance on the financing order by parties who are not involved with this suit.

While we decline to vacate the decisions below, our opinion should not be read as an affirmance of the underlying decisions on the merits. We note, moreover, that many of these issues remain unresolved at the circuit level. They must await a live, redressable controversy for resolution by this court. These appeals are DISMISSED.
Notes
. Section 1110 provides, in relevanL part, as follows:
(a)(1) The right of a secured party with a security interest in equipment described in paragraph (2) or of a lessor or conditional vendor of such equipment to take possession of such equipment in compliance with a security agreement, lease, or conditional sale contract is not affected by section 362, 363 or 1129 or by any power of the court to enjoin the taking of possession unless—
(A) before the date that is 60 days after the date of the order for relief under this chapter, the trustee, subject to the court's approval, agrees to perform all obligations of the debtor that become due on or after the date of the order under such security agreement, lease, or conditional sale contract; and
(B) any default, other than a default of a kind specified in section 365(b)(2) under such security agreement, lease, or conditional sale contract—
(i) that occurs before the date of the order is cured before the expiration of such 60-day period; and
(ii) that occurs after the date of the order is cured before the later of—
(I) the date that is 30 days after the date of the default; or
(II) the expiration of such 60-day period.
. There is no contention that the providers of post-petition financing to WestPac did not extend credit in good faith.
. "[E]ven though [§ ] 364(e) standing alone does not require dismissal of an appeal when a slay is not granted, it might establish circumstances which under law 'other than [§ ] 364(e) require dismissal of the appeal”

. This sanction stems from proceedings involving the third of Boullioun’s aircraft, eventually leased to Olympic Airways of Greece. When, on March 10, 1998, the district court ruled that § 1110 ceases to apply once a debtor in possession agrees to perform aircraft lease obligations and cures initial defaults, Boullioun had already sold two of its aircraft in reliance on a prior lease rejection order by the bankruptcy court. Boullioun was in the process of leasing the third aircraft to Olympic Airways. Following the district court's March 10 order, on April 30, 1998, the bankruptcy court upheld the earlier rejection order as to the two aircraft already sold, but vacated its earlier rejection order as to the third aircraft.
Subsequently, on August 24, 1998, the bankruptcy court again deemed WestPac’s lease of the third aircraft rejected, and validated the lease to Olympic Airways. However, the bankruptcy court ruled that Boullioun had violated the automatic stay by obtaining the replacement lease of the third aircraft following the April 30 order, and that the Estate was entitled to compensation for the attorney fees incurred by WestPac relating to the third aircraft. This amount was subsequently fixed at $4,000.
By order dated February 16, 1999, the bankruptcy court approved a settlement between Boullioun and the trustee regarding the amount and priority of Boullioun's claims. The settlement provided "that Boullion shall pay the Trustee the sum of $4,000 in accordance with the August 24, 1998 Order, subject to refund if the Tenth Circuit rules there was no stay violation.” In re Western Pacific Airlines, Inc., Case No. 97-24701 SBB at 2 (Bankr.D.Colo. Feb. 16, 1999).
.As noted above, the bankruptcy court ruled in February of 1998 that WestPac’s lease defaults entitled Boullioun to repossess its aircraft pursuant to § 1110.
. In this order the bankruptcy court denied Boullioun's motion for relief under §.1110.
. This decision dismisses as moot Boullioun’s appeal of the bankruptcy court’s order authorizing the DIP financing. ;
