    Ernesto D. SIGMON, individually and on behalf of all others
    similarly situated; William Gregory Hassler, individually and on
    behalf of all others similarly situated, Plaintiffs-Appellants,
    v.
    SOUTHWEST AIRLINES COMPANY, Defendant-Appellee.
    April 28, 1997.
    Appeal from the United States District Court for the Northern
    District of Texas.
    Before DUHÉ, BENAVIDES and STEWART, Circuit Judges.
    BENAVIDES, Circuit Judge:
    This     appeal   requires     us        to   determine     whether   airline
    passengers can bring suit against an airline to obtain refunds of
    amounts erroneously collected by the airline as federal excise
    taxes.    We conclude that they cannot.
    In   late    1995,   Ernesto    Sigmon         and    William   Hassler   each
    purchased    an   airline   ticket   from          Southwest    Airlines   Company
    ("Southwest") for travel in 1996. In addition to the ticket price,
    Southwest included a 10% charge on each ticket.                   Southwest added
    the 10% charge to all tickets sold on or before December 31, 1995,
    including tickets for travel in 1996.                     Southwest charged this
    amount in expectation that Congress would renew a longstanding
    excise tax on domestic airline tickets.1                  See 26 U.S.C. § 4261.
    1
    The parties entered into the following stipulation:
    Throughout the period from July 1995 through January
    1996, Southwest Airlines knew that the ten percent (10%)
    1
    Congress had repeatedly renewed the airline ticket excise tax
    provision at the eleventh hour.       See Pub.L. No. 88-52, § 3(a)(3),
    77 Stat. 72 (1963);     Pub.L. No. 88-348, § 2(a)(3), 78 Stat. 237
    (1964);    Pub.L. No. 89-44, § 303(a), 79 Stat. 136, 148 (1965);
    Pub.L. No. 100-223, § 402(a)(1), 101 Stat. 1486, 1532 (1987);
    Pub.L. No. 101-508, § 11213(d)(1), 104 Stat. 1388-435 (1990).
    Southwest's expectation that the tax once again would be renewed
    was disappointed when President Clinton vetoed the bill containing
    the airline ticket excise tax.        The tax expired on December 31,
    1995.     Although Congress reenacted the tax nearly nine months
    later, the tax was not given retroactive application.      Pub.L. No.
    104-188, § 1609(b), 110 Stat. 1755, 1841 (1996).2
    When the excise tax provision expired at the end of 1995,
    excise tax Southwest Airlines was required by 26 U.S.C.
    § 4261 to collect on tickets sold by Southwest Airlines
    for travel on or before December 31, 1995, had not been
    extended by Congress to apply to tickets sold for travel
    on or after January 1, 1996, and that no statute in force
    at any time in 1995 required an excise tax to be
    collected on tickets sold by Southwest Airlines for
    travel on or after January 1, 1996. Nevertheless, based
    on Southwest Airlines' expectation throughout the second
    half of 1995 that Congress and the President would extend
    the application of 26 U.S.C. § 4261 or otherwise enact a
    statute requiring the collection of a ten percent (10%)
    excise tax on tickets sold by Southwest Airlines for
    travel on or after January 1, 1996, Southwest Airlines
    collected from customers who purchased tickets in 1995
    for travel on or after January 1, 1996, an amount equal
    to the ten percent (10%) excise tax that Southwest
    Airlines was required by 26 U.S.C. § 4261 to collect on
    tickets sold by Southwest Airlines for travel on or
    before December 31, 1995.
    2
    The tax expired again on December 31, 1996, and was reenacted
    on February 28, 1997. Pub.L. No. 105-2, § 2(b)(1), 111 Stat. 4
    (1997).
    2
    Southwest had already collected the tax on tickets sold during 1995
    for travel during 1996.    Ultimately, the taxes collected on these
    tickets,     including    those   purchased   by   putative    class
    representatives Sigmon and Hassler,3 were not owed;   the excise tax
    provision in effect in 1995 imposed the tax based on the date of
    travel rather than the date of purchase.4      The total amount of
    erroneously collected excise taxes at issue is unclear;    Southwest
    remitted approximately $18 million to the IRS in January of 1996
    for all excise taxes collected during December of 1995.
    Sigmon and Hassler allege that they requested refunds from
    Southwest and that Southwest denied their requests.    They brought
    a class action suit in state court, alleging common-law causes of
    action for fraud, "for money had and received," and for conversion.
    Southwest removed the suit to federal district court.     Sigmon and
    Hassler did not move to remand the case to state court.           In
    addition to actual damages, they seek attorneys' fees and costs,
    exemplary damages, and pre- and post-judgment interest.
    Shortly after removal, Southwest filed a motion to dismiss the
    plaintiffs' complaint.    In response, plaintiffs moved for leave to
    amend their complaint; the district court granted the motion. The
    plaintiffs' amended complaint asserted an implied cause of action
    3
    The case was dismissed before any class was certified.
    4
    When Congress reenacted the tax in February of 1997, it
    solved the dilemma faced by Southwest and other airlines in 1995 as
    a result of the previous lapse.           Congress added Section
    4261(g)(1)(B), which applies the excise tax to tickets purchased
    before the expiration of the tax for transportation beginning after
    the expiration date.    Pub.L. No. 105-2, § 2(b)(1), 111 Stat. 4
    (1997).
    3
    under 26 U.S.C. § 6415(c) and alleged that Southwest had failed to
    remit to the IRS the amounts collected as excise taxes.5                   After
    plaintiffs filed their amended complaint, Southwest moved to have
    its motion to dismiss be treated as a motion for summary judgment.
    The district court granted Southwest's motion and allowed the
    parties to submit summary judgment evidence.
    On May 23, 1996, the district court granted summary judgment
    in favor of Southwest on three grounds:            (1) the Internal Revenue
    Code, 26 U.S.C. § 7422, preempts the plaintiffs' claims;             (2) the
    Airline   Deregulation    Act,   49       U.S.C.   §   41713,   preempts    the
    plaintiffs' claims;      and (3) 26 U.S.C. § 6415 does not create an
    implied cause of action in favor of the plaintiffs.
    I.
    On appeal, Sigmon and Hassler assert that the district court
    lacked subject-matter jurisdiction because they asserted only state
    common-law causes of action against Southwest Airlines in their
    state-court petition.     Southwest Airlines removed to federal court
    5
    Although the parties fought long and hard in the district
    court about whether Southwest actually remitted the collected
    amounts to the IRS, the appellants do not pursue this line of
    argument on appeal. Rather, they argue that regardless of whether
    the collected funds were remitted to the IRS, Southwest is not
    entitled to protection from suit under the Internal Revenue Code.
    Even if appellants had raised the issue, however, it appears that
    Southwest did remit the taxes it collected, although it took
    credits and deductions against those amounts and remitted its net
    tax liability.   In support of its motion for summary judgment,
    Southwest submitted the affidavit of Rhonda Heatley, Southwest's
    Senior Tax Accountant, who swore that "all excise tax proceeds
    collected by Southwest Airlines Company on or prior to December 31,
    1995 have been remitted to the United States government" and that
    "Southwest Airlines Company no longer has possession or control of
    any such monies."
    4
    on the ground that plaintiffs stated federal claims under 26 U.S.C.
    §§ 4261 and 6415.      The plaintiffs' state-court petition cites 26
    U.S.C. § 6415(c), which they now claim provides them with an
    implied federal cause of action.           We need not decide whether the
    reference    to   Section   6415(c)   in    the   state-court    petition   is
    sufficient   to   create    a   federal    question,   because   plaintiffs'
    amended federal complaint clearly states an implied cause of action
    under 26 U.S.C. § 6415(c).            This claim constitutes a federal
    question and thus gives the district court original jurisdiction
    under 28 U.S.C. § 1331.
    Although subject-matter jurisdiction is generally assessed as
    of the time of removal, there is an exception if the plaintiff
    voluntarily amends his or her complaint after removal to add a
    federal cause of action, and the case is "tried on the merits
    without objection."     See Kidd v. Southwest Airlines Co., 
    891 F.2d 540
    , 547 (5th Cir.1990).6           In this case, the district court
    acquired jurisdiction, if it did not already exist, when the
    plaintiffs amended their federal complaint to include an implied
    cause of action under federal law.           See 
    id. at 546
    ("[A]lthough
    [plaintiff's] initial complaint was not removable, [plaintiff's]
    decision to "throw in the towel' and amend his complaint to state
    an "unmistakeable federal cause of action' conferred original
    jurisdiction on the federal court.") (quoting Bernstein v. Lind-
    Waldock & Co., 
    738 F.2d 179
    , 185 (7th Cir.1984)).
    6
    Summary judgment is equivalent to a trial on the merits for
    the purpose of this rule. 
    Id. at 546
    (citations omitted).
    5
    The district court had discretion to exercise supplemental
    jurisdiction over plaintiffs' pendent state-law claims.           28 U.S.C.
    § 1367(a), (c)(3);      see also Cinel v. Connick, 
    15 F.3d 1338
    , 1344

    , 
    115 S. Ct. 189
    , 
    130 L. Ed. 2d 122
    (1994).    The district court's decision to retain jurisdiction
    in this case was far from an abuse of discretion, especially given
    that the court disposed of the plaintiffs' pendent state-law claims
    based on federal preemption.      Cf. Statland v. American Airlines,
    Inc., 
    998 F.2d 539
    , 541 (7th Cir.) (after affirming the district
    court's conclusion that the Federal Aviation Act did not create an
    implied cause of action in favor of plaintiffs, the court of
    appeals     exercised   supplemental     jurisdiction   to   dispose    of
    plaintiffs'     remaining    state-law     claims   based    on    federal
    preemption), cert. denied,

    (1993).
    II.
    The Internal Revenue Code governs tax refund suits.          Under
    Section 7422(a) of the Code, a taxpayer7 who seeks a refund of
    federal taxes must first make an administrative refund claim with
    the Secretary of the Treasury.         "No suit or proceeding shall be
    maintained in any court for the recovery of any internal revenue
    tax alleged to have been erroneously or illegally assessed or
    collected ... until a claim for refund or credit has been duly
    filed with the Secretary...."      26 U.S.C. § 7422(a).       Failing an
    7
    Airline ticket purchasers, not airlines, are the taxpayers of
    the airline ticket excise tax. See 26 U.S.C. § 4261(d).
    6
    administrative resolution, the taxpayer's remedy is to file suit
    against the government.        26 U.S.C. § 7422(f)(1)("A suit [for
    erroneously or illegally assessed or collected taxes] may be
    maintained only against the United States ....")(emphasis added);
    Kaucky    v.   Southwest   Airlines       Co.,   
    109 F.3d 365
    ,    370   (7th
    Cir.1997)("Money collected in error by a lawful agent, public or
    private, of the [IRS] can be recovered only from the government,
    because a claim or suit to collect such money is a claim or suit
    for a tax refund.").
    Southwest acts as the government's agent in collecting
    airline ticket excise taxes.     26 U.S.C. § 4291;            see also 
    Kaucky, 109 F.3d at 368
    .       Section 7422 protects from lawsuits private
    entities, like Southwest, that are required by statute to collect
    taxes for the government under threat of criminal penalty for
    failure to do so.    DuPont Glore Forgan Inc. v. AT & T, 
    428 F. Supp. 1297
    , 1306 (S.D.N.Y.1977), aff'd, 
    578 F.2d 1366
    (2d Cir.), cert.

    (1978).8
    Although appellants seek the return of amounts collected by
    Southwest to pay anticipated excise taxes, they argue that the
    Internal Revenue Code's refund scheme does not apply.                The amounts
    collected, they argue, were not "taxes" because the excise tax
    8
    Other courts in other contexts have likewise held that if
    taxpayers seek to compel a refund, they must proceed against the
    United States rather than against a private tax collector. See,
    e.g., Burda v. M. Ecker Co., 
    954 F.2d 434
    , 439 (7th Cir.1992)
    (employment tax);    Econ, Inc. v. Illinois Bell Tel. Co., 
    351 F. Supp. 1087
    , 1089 (N.D.Ill.1972) (communications excise tax); see
    also Columbia Marine Servs., Inc. v. Reffet Ltd., 
    861 F.2d 18
    , 22
    (2d Cir.1988).
    7
    statute was not reenacted.           It is literally true that the amounts
    collected ultimately were not taxes.                  For the reasons that follow,
    however, "we do not think the literal sense is the right sense."
    
    Kaucky, 109 F.3d at 368
    .
    Appellants advance two hypotheticals in support of their
    position.    Suppose, they posit, a law firm added a 10% surcharge to
    its fees and called it a "federal excise tax," when no such tax
    existed.    Or what if an airline dreamed up a 5% "carry on luggage
    tax"? The government would have no interest in the collected funds
    because they are not really "taxes."                   The culpable tax collectors
    would not deserve the protection of Section 7422 because they were
    not really acting as agents for the government.                      Southwest, they
    argue, is no different from their hypothetical tax collectors.
    Unlike    the     defendants     in       these     hypotheticals,        however,
    Southwest was not imposing a make-believe tax, nor did it dream up
    a surcharge and pocket the money for itself.                          Southwest was
    collecting     an   excise    tax    that       has    been   part   of   the    airline
    passenger ticket sales landscape for nearly four decades. Here, it
    was stipulated that Southwest "expect[ed] throughout the second
    half of 1995 that Congress and the President would extend the
    application of 26 U.S.C. § 4261 or otherwise enact a statute
    requiring the collection of a ten percent (10%) excise tax on
    tickets sold by Southwest Airlines for travel on or after January
    1, 1996."    Thus, Southwest was acting as an agent of the government
    in   collecting     a   tax   that   it     had       every   expectation       would    be
    reenacted, as it had been on several previous occasions.                                See
    8
    
    Kaucky, 109 F.3d at 368
    .
    Citing    Enochs     v.     Williams       Packing    &   Navigation    Co.,
    appellants contend that, Section 7422 notwithstanding, they may sue
    Southwest     because     Southwest         lacked     a    "colorable   basis"   for
    collecting the anticipated excise tax.                 
    370 U.S. 1
    , 
    82 S. Ct. 1125
    ,
    
    8 L. Ed. 2d 292
    (1962).          The Supreme Court in Enochs acknowledged a
    limited exception to 26 U.S.C. § 7421, which prohibits the courts
    from issuing injunctions against the collection of taxes.                         See
    Miller v. Standard Nut Margarine Co., 
    284 U.S. 498
    , 509, 
    52 S. Ct. 260
    , 263, 
    76 L. Ed. 422
    (1932).                    Under the Enochs exception, a
    taxpayer can obtain an injunction against the collection of taxes
    if it is "clear that under no circumstances could the Government
    ultimately prevail ..." and equity jurisdiction otherwise exists.
    
    Enochs, 370 U.S. at 6-7
    ,    82    S.Ct.     at   1128-29.     The   Enochs
    exception, however, has never been applied to allow a taxpayer to
    sue a private tax collector for the refund of erroneously collected
    taxes.9    We need not decide whether the Enochs exception loosens
    the strictures of Section 7422;                  Enochs is not satisifed in this
    case because Southwest was acting with colorable authority when it
    collected the tax.        See 
    Kaucky, 109 F.3d at 369
    .              Appellants argue
    that "[n]either the IRS nor Southwest Airlines could conceivably
    9
    To allow an exception to Section 7422 based on a lack of a
    colorable basis, especially if evaluated at the time suit is filed,
    would open Pandora's box.    Plaintiffs, in search of common-law
    damages in addition to a tax refund, would have strong incentives
    to attempt to bypass the normal administrative tax refund process.
    Such an exception would allow taxpayers to seek a judicial
    resolution of whether a collected tax was colorable before
    challenging the tax through the administrative process provided by
    the IRS.
    9
    prove that Southwest Airlines properly collected the "excise taxes'
    in issue."      Although it is now apparent that passengers who paid
    the excise tax in 1995 for travel in 1996 are entitled to a refund
    from the IRS, that ex post knowledge does not establish that
    Southwest lacked a colorable basis for collecting the tax.                 The
    issue is whether Southwest had a colorable basis to collect the tax
    at the time.
    Although the collection may ultimately have been erroneous,
    the Internal Revenue Code provides the exclusive remedy for the
    erroneous or illegal collection of taxes: The taxpayer may file an
    administrative claim for a refund with the IRS. If the IRS does not
    return the erroneously or illegally collected tax, the taxpayer may
    then resort to the courts.          But under Section 7422, the proper
    defendant in such a suit is the United States, not Southwest.              The
    exclusive     remedy   provided   by    the   Internal   Revenue   Code   thus
    preempts     the   appellants'    state-law    claims    against   a   private
    entity.10
    III.
    Appellants also ask this court to hold that 26 U.S.C. §
    6415(c) creates a private cause of action for the return of the
    erroneously collected amounts.           That section provides that if a
    private collector of excise taxes "make[s] an overcollection of
    such tax, such person shall, upon proper application, refund such
    10
    Because we conclude that appellants' claims are precluded by
    26 U.S.C. § 7422, we need not determine the propriety of the
    district court's conclusion that these claims are preempted by the
    Airline Deregulation Act.
    10
    overcollection to the person entitled thereto."                26 U.S.C. §
    6415(c).    Appellants claim that the plain language of this statute
    creates a federal right for their benefit, which they are entitled
    to enforce in a private cause of action in state or federal court
    against Southwest.    We disagree.
    As an initial matter, Section 6415(c) may not even apply to
    the sort of refund sought by the appellants in this case.                See
    
    Kaucky, 109 F.3d at 370
    (citing AT & 
    T, 428 F. Supp. at 1304-05
    and
    Lehman v. USAIR Group, Inc., 
    930 F. Supp. 912
    , 915 (S.D.N.Y.1996)).
    Section 6415(c) on its face is limited to "overcollection" of
    excise   taxes,   which    has    historically   been   distinguished    from
    "illegal" or "erroneous" collection under Section 7422.                 Early
    Treasury regulations explained that "overcollection" referred only
    to cases in which "an excess amount [was] collected or paid" "as a
    result of some clerical or mechanical error."           See Treas.   Reg. 43,
    art.   65   (1921).       The    traditional   distinction   between    taxes
    collected as the result of a mechanical or clerical error and taxes
    collected because of an error of law makes sense.            The IRS has no
    interest in taxes collected purely as a result of mechanical or
    clerical error and hence need not be involved in the refund
    decision.    If excise taxes are collected as the result of a legal
    error, however, the IRS's interest in being involved in the refund
    decision is apparent.       In the case of a legal error, the private
    tax collector would also risk being unable to recover the amounts
    refunded if the IRS determined the amount in fact was owed.            See AT
    & 
    T, 428 F. Supp. at 1306
    .

    Of course, in this case, there is no dispute that the taxes
    were not ultimately owed.              But if Section 6415(c) creates a right
    of action and applies to collections due to an error of law, as the
    appellants suggest, there is no principle by which the right would
    be limited to cases in which the tax was clearly not owed.                        Under
    appellants'        interpretation,        Section     6415(c)    would     allow     any
    taxpayer to        challenge     any     excise   tax    in   court    without     first
    complaining to the IRS. If, for example, the appellants alleged
    that Southwest had misinterpreted the statute and as a result
    collected        taxes   erroneously,       nothing     would   prevent    them     from
    seeking      a    refund   in    court     before     seeking   an     administrative
    resolution through the IRS. No rational basis exists for giving
    excise taxpayers special access to the courts that is denied all
    other taxpayers under Section 7422.                 See AT & 
    T, 428 F. Supp. at 1304
    .
    Even if Section 6415(c) does apply in this case, it does not
    create a private right of action enforceable in federal district
    court.    No court appears to have recognized an implied private
    cause of action under Section 6415(c), and with good reason.                         See
    
    Kaucky, 109 F.3d at 370
    ;              AT &

    ;        
    Lehman, 930 F. Supp. at 915
    . In evaluating whether a federal statute creates an
    implied cause of action, this circuit has applied the four factors
    set forth by the Supreme Court in Cort v. Ash:                        (1) whether the
    statute creates a federal right or "especial benefit" for a class
    of   which       plaintiffs     are    members;       (2)   whether    there   is    any
    indication of legislative intent, explicit or implicit, to create
    12
    a private cause of action;    (3) whether implying a private cause of
    action would be consistent with the purpose of the legislative
    scheme; and (4) whether the cause of action urged by the plaintiff
    is one traditionally relegated to state law.

    95 S. Ct. 2080
    , 2088, 
    45 L. Ed. 2d 26
    (1975).      In Touche Ross & Co. v.
    Redington, the Supreme Court explained that congressional intent is
    the touchstone for determining whether a federal statute creates a
    private right of action.     
    442 U.S. 560
    , 578, 
    99 S. Ct. 2479
    , 2490,
    
    61 L. Ed. 2d 82
    (1979);   see also Louisiana Landmarks Soc'y, Inc. v.
    City of New Orleans, 
    85 F.3d 1119
    , 1123 (5th Cir.1996) (citations
    omitted). This circuit has recognized a "presumption that Congress
    did not intend to create a private right of action."             Louisiana
    
    Landmarks, 85 F.3d at 1123
    (citation and internal quotation marks
    omitted).   Appellants "bear[ ] the relatively heavy burden of
    demonstrating that Congress affirmatively contemplated private
    enforcement when it passed the relevant statute."            
    Id. (citations and
    internal quotation marks omitted).         They have not met that
    burden.
    Nothing indicates that Congress intended Section 6415(c) to
    create an   exception   to   Section   7422   that   would    allow   excise
    taxpayers to seek relief from the courts in the first instance.
    Congress's failure even to hint that it intended to allow excise
    taxpayers to sue private tax collectors directly for refunds,
    combined with Section 7422's express bar on tax refund suits
    against a defendant other than the United States, compels the
    conclusion that Congress did not intend to provide a private
    13
    remedy. See 
    Kaucky, 109 F.3d at 370
    ("[T]here is ... no indication
    that Congress would have wanted the courts to entertain such suits
    despite the absence of express authorization.").
    The third Cort v. Ash factor is particularly salient on the
    issue of congressional intent.             The structure of the Internal
    Revenue Code shows that Congress intended the courts to play a role
    only after the IRS has been given an opportunity to resolve the
    taxpayer's claims.        We have held that the "existence of [an]
    administrative    scheme    of   enforcement      is   strong    evidence   that
    Congress intended the administrative remedy to be exclusive." Till
    v. Unifirst Federal Sav. & Loan Ass'n, 
    653 F.2d 152
    , 160 (5th
    Cir.1981).   "Indeed, it is clear under the maxim—expressio unius
    est exclusio alterius—that a pervasive remedial scheme provided by
    Congress is an indication there was no intent to provide an
    additional private remedy."        
    Id. Section 6415(c)
    is part of a scheme set up by Congress by
    which taxpayers can obtain refunds from the IRS.                See AT & 
    T, 428 F. Supp. at 1305
    ("[T]he overall structure of the refund provisions
    of the Code negates plaintiffs' efforts to seek a tax refund from
    defendants.").    To recognize a private cause of action against a
    nongovernmental    tax    collector      under   Section   6415(c)    would   be
    inconsistent with that scheme.
    Appellants rely heavily on the word "shall" in 26 U.S.C. §
    6415(c), which provides that a private tax collector "shall, upon
    proper   application,     refund   such    overcollection       to   the   person
    entitled thereto."       They argue that "shall" is a mandatory rather
    14
    than a permissive term and that this fact alone indicates that
    Congress intended to make refunds by private tax collecting agents
    mandatory. But courts do not always construe "shall" as mandatory.
    See, e.g., Board of Governors of the Federal Reserve Sys. v. DLG
    Fin. Corp., 
    29 F.3d 993
    , 1001 (5th Cir.1994), cert. dismissed, ---
    U.S. ----, 
    115 S. Ct. 1085
    , 
    130 L. Ed. 2d 1055
    (1995).            Moreover, we
    are especially reluctant to infer a private cause of action from
    Congress's use of "shall" in Section 6415(c) when another component
    of   the   legislative   scheme,    Section      7422,   indicates    that   an
    aggrieved taxpayer's remedy lies solely in a proceeding against the
    United States.     See 3 NORMAN J. SINGER, SUTHERLAND STATUTORY CONSTRUCTION
    § 57.06, at 20 (5th ed.       1992) ("[I]f the particular provision in
    question is a part of a general legislative scheme, a consideration
    of the entire scheme together may make the particular provision
    clear.     If the construction, mandatory or directory, would produce
    conflict with other statutes, the opposite ruling would ordinarily
    be adopted.").
    Other than their heavy reliance on the statute's use of the
    phrase "shall ... refund," appellants merely point to the absence
    of evidence that Congress did not intend to create a private right
    of   action.     This   is   insufficient   to    overcome   this    circuit's
    presumption against implying causes of action.
    IV.
    Holding that appellants' state-law claims are precluded by
    Section 7422 does not leave consumers at the mercy of the airlines.
    Consumers can seek a refund of any erroneously collected excise
    15
    taxes from the IRS. We recognize that this may inconvenience
    taxpayers.   As a practical matter, however, many taxpayers would
    have been far more inconvenienced if Southwest had failed to
    collect the tax and it had been renewed as expected, especially
    those taxpayers who learned about their tax deficiencies at the
    departure gate.
    Federal law provides an additional protection to consumers.
    The Airline Deregulation Act gives the Secretary of Transportation
    authority to investigate an airline's unfair or deceptive acts or
    practices or unfair methods of competition. See 49 U.S.C. § 41713.
    Upon discovering such an act or practice, the Secretary may issue
    cease-and-desist    orders    or   levy    civil   sanctions   against     an
    offending airline.     Id.;     see also American Airlines, Inc. v.
    Wolens, 
    513 U.S. 219
    , 228 n. 4, 
    115 S. Ct. 817
    , 823 n. 4, 
    130 L. Ed. 2d 715
    (1995) (citations omitted).            We do not suggest that
    such an action would be appropriate against Southwest in this case,
    only that the law provides another protection against the airlines
    engaging in the mischief prophesied by the appellants.
    For   the   foregoing    reasons,    the   summary   judgment   of   the
    district court is AFFIRMED.
