    MURPHY, Circuit Judge.
    I.    Introduction
    Plaintiffs-Appellees, Nazli McDonnell and Eric Verlo, sought a preliminary
    injunction against Defendants, arguing policies and regulations governing protests
    and demonstrations at Denver International Airport (“DIA”) violate their First and
    Fourteenth Amendment rights. The district court granted the injunction in part,
    concluding Plaintiffs made the necessary showing with respect to their claim that
    the challenged regulations are unreasonable because they do not contain a formal
    process for expediting permit applications in exigent circumstances. McDonnell
    v. City & Cty. of Denver, 
    238 F. Supp. 3d 1279
    , 1299-1301 (D. Colo. 2017). The
    district court also enjoined Defendants from enforcing certain regulations
    governing the location of permitted protests and picketing restrictions, including
    the size of signage. 
    Id. at 1301-02
    .
    Exercising jurisdiction under 
    28 U.S.C. § 1292
    (a)(1), we reverse the grant
    of the preliminary injunction.

    II.   Background
    DIA was established and is governed by the City and County of Denver
    Municipal Charter. https://www.flydenver.com/about/administration (last visited
    Dec. 2, 2017). Relevant to the matter before this court, § 5-16(d) of the Denver
    Revised Municipal Code provides as follows:
    The manager of aviation shall have the power and authority, and is
    hereby empowered and authorized, upon the basis of passenger flow
    or where necessitated by the peculiar character of Denver Municipal
    Airport System as an airport, to adopt rules and regulations
    pertaining to the exercise of First Amendment rights, including by
    way of example, but not by way of limitation, solicitation of
    contributions for charitable or religious purposes and the
    dissemination of printed material upon Denver Municipal Airport
    System. Such rules and regulations shall establish reasonable time,
    place and manner guidelines for the exercise of such First
    Amendment rights.
    The rules and regulations governing the management, operation, control, and use
    of DIA include Regulation 50, which regulates “all leafleting, display of signs,
    signature gathering, solicitations of funds and other speech related activity
    conducted at Denver International Airport for religious, charitable, or political
    purposes, or in connection with labor disputes.” Denver Revised Mun. Code
    § 50.01. Regulation 50.03 prohibits any person or organization from engaging in
    speech-related activity at DIA for religious, charitable, or political purposes
    without first obtaining “a permit for such activity issued by the [Chief Executive
    Officer of Aviation] or his or her designee.” Id. § 50.03; McDonnell, 238 F.
    Supp. 3d at 1285-86. An application to obtain the required permit must be
    -3-
    submitted “at least seven (7) days prior to the commencement of the activity for
    which the permit is sought.” McDonnell, 238 F. Supp. 3d at 1286 (quoting
    Denver Revised Mun. Code § 50.04–1).
    On January 28, 2017, an unpermitted protest was held at DIA in an interior
    area of Jeppesen Terminal colloquially known as the “Great Hall.” Id. at 1287-
    88. The protest was in response to Executive Order 13769 which, inter alia,
    temporarily suspended entry into the United States of nationals from seven
    predominantly Muslim countries. Protecting the Nation From Foreign Terrorist
    Entry Into the United States, Exec. Order No. 13769 of January 27, 2017, 
    82 Fed. Reg. 8977
     (Feb. 1, 2017). A second unpermitted protest, which was organized
    and attended by the Plaintiffs, was held in Jeppesen Terminal on January 29,
    2017. McDonnell, 238 F. Supp. 3d at 1289. The January 28th protest was
    allowed to continue without a permit but protestors were eventually moved from
    the Great Hall to an outdoor plaza. Id. at 1289. The January 29th protest took
    place near the international arrival area at the north end of the Great Hall and
    continued for several hours. Id. Although protestors on both days were warned
    they could be arrested for continuing to demonstrate without a permit, no arrests
    were made. Id. The district court’s order contains a comprehensive description
    of both protests. Id. at 1287-89.
    On February 6, 2017, Plaintiffs filed a complaint in the United States
    District Court for the District of Colorado challenging the permitting process set
    -4-
    out in Regulation 50. Plaintiffs alleged violations of their First and Fourteenth
    Amendment rights and sought, inter alia, compensatory damages, injunctive
    relief, and a declaration that Regulation 50 is unconstitutional on its face. On the
    same day, Plaintiffs filed a Motion for Preliminary Injunction, seeking “an
    injunction prohibiting their arrest for standing in peaceful protest within Jeppesen
    Terminal.” Plaintiffs asserted they were likely to succeed on the merits of their
    claim that Regulation 50 is a prior restraint that prohibits them from engaging in
    speech protected by the First Amendment. Arguing DIA is a public forum, they
    claimed Regulation 50 is facially unconstitutional because it is content-based and
    not narrowly tailored to serve a compelling government interest. Cf. Cornelius v.
    NAACP Legal Def. & Educ. Fund, Inc., 
    473 U.S. 788
    , 800 (1985) (holding
    “speakers can be excluded from a public forum only when the exclusion is
    necessary to serve a compelling state interest and the exclusion is narrowly drawn
    to achieve that interest”); cf. also Verlo v. Martinez, 
    820 F.3d 1113
    , 1129 (10th
    Cir. 2016) (discussing the three speech forums: the traditional public forum, the
    designated public forum, and the nonpublic forum). In the alternative, Plaintiffs
    argued they were likely to succeed on the merits of their claim even if DIA is
    determined to be a nonpublic forum because the restrictions on speech imposed
    by Regulation 50 are not reasonable. Cf. Cornelius, 
    473 U.S. at 800
     (“Access to a
    nonpublic forum . . . can be restricted as long as the restrictions are reasonable
    and are not an effort to suppress expression merely because public officials
    -5-
    oppose the speaker’s view.” (quotation and alteration omitted)). Plaintiffs’
    argument included an assertion the seven-day advance notice requirement for
    obtaining a permit is not a reasonable restriction on First Amendment rights.
    Plaintiffs’ briefing did not include any argument on signage restrictions.
    The district court held a full-day hearing at which Plaintiffs and Defendants
    presented testimony. At the beginning of the hearing, the district court informed
    the parties it had determined DIA is a nonpublic forum and intended to apply a
    reasonableness standard to its analysis of Regulation 50. Plaintiffs and
    Defendants then presented the testimony of several individuals, including the
    Plaintiffs, a legal observer who attended the January 28th protest, the chief
    operating officer of DIA, the assistant director for terminal operations at DIA, and
    the law enforcement officer responsible for all police services at DIA. At the
    conclusion of the hearing, the district court asked Plaintiffs’ counsel to state what
    Plaintiffs would include in the preliminary injunction if one was granted. In
    response, counsel stated:
    I would enjoin defendants from . . . arresting people for engaging in
    behavior that the plaintiffs or people similarly situated are engaging
    in. I would enjoin 50.09 of Regulation 50 as being overbroad. And I
    think the permit requirement[] is also overbroad.
    I don’t—I don’t know if there is necessarily a need for no permit
    requirement, I don’t—I wouldn’t say that DIA can’t implement a
    permit requirement of some nature, but certainly having no exigent
    circumstances exception is not acceptable under the First
    Amendment. And the length of the—the notice requirement is
    unconstitutional.
    -6-
    On February 22, 2017, the district court entered an order granting the
    injunction in part, and denying it in part. As to Plaintiffs’ argument that DIA is a
    public forum, the court noted the Supreme Court has definitively held that airport
    terminals are nonpublic forums. Int’l Soc’y for Krishna Consciousness, Inc. v.
    Lee, 
    505 U.S. 672
    , 678-81 (1992); see also Mocek v. City of Albuquerque, 
    813 F.3d 912
    , 930 (10th Cir. 2015) (recognizing the Supreme Court’s ruling that
    airports are nonpublic forums). The district court further concluded that DIA is
    not a designated public forum. See Cornelius, 
    473 U.S. at 802
     (holding a
    government entity may create a designated public forum by intentionally
    designating “a place not traditionally open to assembly and debate as a public
    forum”). Accordingly, it analyzed whether Plaintiffs had a likelihood of success
    on the merits of their claim that Regulation 50 is not reasonable in light of the
    purposes served by DIA. 1 See Lee, 
    505 U.S. at 687
     (O’Connor, J., concurring)
    (stating that any restriction on speech in a nonpublic forum must be reasonable in
    light of the purpose of the forum and all the surrounding circumstances).
    The district court ruled that Plaintiffs were unable to show they are likely
    to succeed on the merits of their claims that Regulation 50’s advance permitting
    requirement, including Regulation 50.03’s seven-day advance notice requirement,
    1
    Noting that the primary purpose of DIA “is to facilitate safe and efficient
    air travel,” the district court recognized that every arriving and departing
    passenger at DIA must pass through the Great Hall. McDonnell v. City & Cty. of
    Denver, 
    238 F. Supp. 3d 1279
    , 1297 (D. Colo. 2017).
    -7-
    is overbroad because it is unreasonable in all circumstances. McDonnell, 238 F.
    Supp. 3d at 1298-99. The district court, however, granted Plaintiffs’ motion, in
    part, concluding Plaintiffs showed a strong likelihood of success on the merits of
    their claim that Regulation 50.03’s lack of a formal process for expediting permit
    applications in exigent circumstances is unreasonable. Id. at 1299-1301. The
    district court further concluded Plaintiffs are likely to succeed on their challenge
    to Defendants’ unfettered discretion to designate the location of permitted
    activity. Id. at 1301. The district court also granted a preliminary injunction as
    to the picketing restriction in Regulation 50.02-8 which prohibits picketing in the
    Jeppesen Terminal unless it is part of a labor protest. Id. at 1301-02. The court
    concluded Plaintiffs showed a likelihood of success on the merits of that claim
    because a ban on picketing “is foreclosed by Justice O’Connor’s analysis of the
    leafleting ban[] at issue in Lee.” Id. at 1301. Finally, the court concluded
    Plaintiffs can likely show Regulation 50.08-12, which restricts the size of signage
    to “one foot by one foot,” is unreasonable. Id. at 1301-02.
    Defendants appeal from the partial grant of the preliminary injunction.
    III.   Discussion
    A. Standard of Review
    A movant is not entitled to a preliminary injunction unless he can show: (1)
    he is likely to succeed on the merits of his claim; (2) he will suffer irreparable
    harm if the injunction is denied; (3) his threatened injury outweighs the harm the
    -8-
    grant of the injunction will cause the opposing party; and (4) if issued, the
    injunction will not adversely affect the public interest. Fish v. Kobach, 
    840 F.3d 710
    , 723 (10th Cir. 2016). Because the grant of a preliminary injunction is “an
    extraordinary remedy,” the movant must make a “clear showing” that he is
    entitled to the injunction. Winter v. Nat. Res. Def. Council, Inc., 
    555 U.S. 7
    , 22
    (2008). Further, the movant must meet a heightened burden if he seeks a
    preliminary injunction, like the one requested by Plaintiffs, that will alter the
    status quo. Fish, 840 F.3d at 723-24. When “seeking such an injunction [the
    movant] must make a strong showing both with regard to the likelihood of success
    on the merits and with regard to the balance of the harms.” O Centro Espirita
    Beneficiente Uniao Do Vegetal v. Ashcroft, 
    389 F.3d 973
    , 976 (10th Cir. 2004)
    (en banc).
    This court reviews the grant of a preliminary injunction for abuse of
    discretion. Westar Energy, Inc. v. Lake, 
    552 F.3d 1215
    , 1224 (10th Cir. 2009). A
    district court abuses its discretion when it “commits an error of law or relies upon
    a clearly erroneous factual finding.” 
    Id.
    B. Likelihood of Success On the Merits
    1. Spontaneous Expression
    The district court concluded Plaintiffs showed a strong likelihood of
    success on the merits of their claim that Regulation 50.03 is facially unreasonable
    because it does not contain a formal written process to obtain a permit in less than
    -9-
    seven days. McDonnell, 238 F. Supp. 3d at 1299-1301. The district court arrived
    at this conclusion notwithstanding its acknowledgment that “serious and
    substantial purposes [are] served by an advance notice requirement.” Id. at 1299.
    The district court abused its discretion when it granted the preliminary injunction
    on this claim.
    Under the “unreasonableness” standard applicable to nonpublic forums,
    Lee, 
    505 U.S. at 687
     (O’Connor, J., concurring), a movant must show a strong
    likelihood of success on the merits. O Centro Espirita, 
    389 F.3d at 976
     (en banc).
    Here, the district court acknowledged “[t]he parties have not cited, nor has the
    Court located, any case specifically discussing the need for a nonpublic forum to
    accommodate short-notice demonstrations.” McDonnell, 238 F. Supp. 3d at 1299.
    The fact that Plaintiffs were unable to locate precedent supporting their position
    on spontaneous speech in a nonpublic forum led the district court to evaluate their
    claims based on case law addressing spontaneous speech in public forums.
    Relying on those cases, the district court concluded Plaintiffs made a strong
    showing that Regulation 50’s lack of a formal exigency policy is unreasonable
    because it “does not account for the possibility of . . . short-notice demonstrations
    regarding suddenly relevant issues.” Id. Analogizing to the twenty-four-hour
    notice the City of Denver requires to prepare for a spontaneous, topical parade on
    a public street, the district court concluded Plaintiffs would likely succeed on
    their claim that Defendants can accommodate a protest at DIA with twenty-four
    -10-
    hours notice in exigent circumstances. Id. The district court’s analysis on this
    issue conflicts with the standard applicable to nonpublic forums and fails to apply
    the standard relevant to a preliminary injunction that disrupts the status quo.
    A ruling that a plaintiff has a strong likelihood of success on the merits is
    based on the evidence plaintiff intends to present at trial, particularly when, as in
    this matter, plaintiffs cannot identify any case law supporting their position. Cf.
    Port City Props. v. Union Pac. R.R. Co., 
    518 F.3d 1186
    , 1190-91 (10th Cir. 2008)
    (“[T]he district court held that [movant] failed to show a likelihood of success on
    the merits because it offered no evidence of a contract requiring Union Pacific to
    provide rail service to it.”); Hawkins v. City & Cty. of Denver, 
    170 F.3d 1281
    ,
    1290 (10th Cir. 1999) (“Lee describes the reasonableness test as a
    factually-intensive, individualized inquiry.”); see also McNeilly v. Land, 
    684 F.3d 611
    , 620 (6th Cir. 2012) (affirming denial of a preliminary injunction because
    movant failed to present sufficient evidence to show a likelihood of success on
    the merits). Here, the district court referenced the testimony of three airport
    administrators as support for its conclusion Plaintiffs could not show a strong
    likelihood of success on the merits of their claim that the seven-day advance
    notice requirement is unreasonable in all circumstances. McDonnell, 238 F.
    Supp. 3d at 1297-99 (summarizing testimony on the need for Defendants to have
    advance notice of a protest so they can instruct demonstrators on permissible
    activities, determine whether additional security is needed, understand the subject
    -11-
    matter of the protest as it relates to the need for additional security, and determine
    an appropriate location for the protest). The court, however, ignored that same
    testimony when it concluded Plaintiffs will likely prevail on their claim
    Regulation 50 is unreasonable because it does not allow speakers to obtain a
    permit with only twenty-four hours notice in exigent circumstances. Instead, the
    district court’s conclusion was, by the court’s own admission, not based on any
    record evidence but was, instead, based on “cases regarding public fora (streets
    and parks) [that] have held or strongly suggested that an advance notice
    requirement is unconstitutional if it does not account for the possibility of
    spontaneous or short-notice demonstrations regarding suddenly relevant issues.” 2
    Id. at 1291-92, 1299 (referencing American–Arab Anti–Discrimination Comm. v.
    2
    As already noted, Plaintiffs have not identified any cases so holding in
    situations involving nonpublic forums. The absence of such precedent is
    unsurprising. Because public forums occupy a “special position in terms of First
    Amendment protection due to their historic role as sites for discussion and
    debate,” the government’s power to restrict speech in a traditional public forum is
    “very limited.” McCullen v. Coakley, 
    134 S. Ct. 2518
    , 2529 (2014) (quotation
    omitted). The government may impose time, place, and manner restrictions only
    if they serve a significant government interest, are narrowly tailored, and provide
    alternative channels of communication. 
    Id.
     Nonpublic forums do not have the
    same “traditionally open character of public streets and sidewalks.” 
    Id.
    Accordingly, “[a]ccess to a nonpublic forum . . . can be restricted as long as the
    restrictions are reasonable and are not an effort to suppress expression merely
    because public officials oppose the speaker’s view.” Cornelius v. NAACP Legal
    Def. & Educ. Fund, Inc., 
    473 U.S. 788
    , 800 (1985) (quotation and alternation
    omitted); see also PeTA, People for the Ethical Treatment of Animals v.
    Rasmussen, 
    298 F.3d 1198
    , 1204 (10th Cir. 2002) (“Content-neutral speech
    restrictions in a public forum are subject to strict scrutiny, while content-neutral
    restrictions in a nonpublic forum are subject to a reasonableness test.”).
    -12-
    City of Dearborn, 
    418 F.3d 600
    , 605 (6th Cir. 2005) (“Any notice period is a
    substantial inhibition on speech.”); Church of Am. Knights of Ku Klux Klan v.
    City of Gary, 
    334 F.3d 676
    , 682 (7th Cir. 2003) (“[G]iven that . . . political
    demonstrations are often engendered by topical events, a very long period of
    advance notice with no exception for spontaneous demonstrations unreasonably
    limits free speech.”); Douglas v. Brownell, 
    88 F.3d 1511
    , 1524 (8th Cir. 1996)
    (“The five-day notice requirement restricts a substantial amount of speech that
    does not interfere with the city’s asserted goals of protecting pedestrian and
    vehicle traffic, and minimizing inconvenience to the public.”)). The substantial
    difference between the legal standard applicable to a public forum and the
    standard applicable to a nonpublic forum renders the comparison inappropriate
    and legally erroneous.
    Because it erroneously relied on principles applicable only to public
    forums, the district court failed to engage in the inquiry actually applicable to
    nonpublic forums when it resolved the exigency issue. Regulations governing
    speech in a nonpublic forum are evaluated by analyzing the reasonableness of the
    restriction in light of the purpose of the forum. Reasonableness is measured by
    evaluating the government’s interest in “preserving the property for the use to
    which it is lawfully dedicated.” Lee, 
    505 U.S. at 688
     (O’Connor, J., concurring)
    (quotations and alterations omitted); Cornelius, 
    473 U.S. at
    799-800 . Any
    restriction “need only be reasonable; it need not be the most reasonable or the
    -13-
    only reasonable limitation.” Cornelius, 
    473 U.S. at 808
    . In Lee, the Supreme
    Court upheld a ban on face-to-face solicitation at an airport as reasonable because
    such solicitation was “incompatible with the airport’s functioning.” 
    505 U.S. at 690
     (O’Connor, J., concurring) (interacting with or avoiding solicitors would
    cause congestion because travelers are carrying baggage and frequently facing
    time constraints); Hawkins, 
    170 F.3d at 1291
     (upholding restrictions on picketing
    and leafleting at the entrance to a performance venue because such activities were
    inconsistent with nonpublic forum’s “limited purpose as an entertainment
    venue”). Accordingly, restrictions on speech in a nonpublic forum are not
    categorically unreasonable because they prevent near-spontaneous protests in the
    location “most obviously relevant” to the speaker. McDonnell, 238 F. Supp. 3d
    at 1299-1301. Because the district court engrafted public forum considerations
    onto the reasonableness standard applicable in cases involving a nonpublic forum,
    it erred in its analysis of the exigency issue.
    The district court further erred by relying on its own belief that Defendants
    could shorten the permit period to twenty-four hours in exigent circumstances,
    choosing the twenty-four-hour period because that “is all the notice Denver needs
    to prepare for a street parade.” Id. at 1300 n.5. The court’s finding that
    Defendants are able to process permit applications and adequately prepare for a
    protest within twenty-four hours finds no support in the record and the court
    failed to engage in any evidence-based comparison of the differences between
    -14-
    street parades and airport protests. 3 Id. (“At the Preliminary Injunction Hearing,
    Defendants’ counsel argued that preparing for a street parade is actually easier
    than preparing for demonstrations at the airport. The Court cannot fathom how
    this could possibly be the case, at least when comparing a typical street parade
    request to the typical Airport demonstration request.”). To the contrary, the
    district court’s finding is incompatible with testimony presented at the hearing.
    In response to questioning from the district court, Commander Lopez testified
    that five days is required to adequately prepare for a protest at DIA.
    [Commander Lopez]: . . . [F]ive days would have given me enough
    time to get help from downtown and get enough resources in place.
    The Court: Is there any reason why that couldn’t—putting aside
    budget, that couldn’t be done in three days?
    [Commander Lopez]: That’s kind of tight.
    The Court: Why is that?
    [Commander Lopez]: Depending on what other events are being
    held downtown, then trying to coordinate the movement of personnel
    3
    For example, DIA’s chief operating officer, Kenric Greene, testified that
    the Great Hall is a “controlled area” and there are numerous “constraints” on the
    public’s ability to access areas accessible from the Great Hall. Mr. Greene also
    testified that the creation of TSA has “made the terminal a more crowded space”
    because passengers are now required to congregate in security areas. The district
    court noted that “every arriving and departing passenger at the Airport . . . must
    pass through some portion of the Great Hall.” The Airport served 58.3 million
    passengers in 2016 and 36,000 people worked there. McDonnell, 238 F. Supp. 3d
    at 1288. Commander Lopez testified that routine security activities at DIA
    include foot patrols, car patrols, assistance at TSA screening points, and escorting
    bomb dogs through the airport.
    -15-
    with three days’ notice might be harder to do. I mean, anything is
    doable; if we have to do it, we have to do it. As we demonstrated on
    the 28th and the 29th, we threw people together in a hurry to try to
    accommodate public safety, but preferably five days would be okay.
    Three days would, I think, be a stretch given vacations, days off, and
    we’re having a lot of First Amendment activity downtown, and
    resources are being drawn into that. So in light of the current times,
    three days is really tight for us.
    The Court: All right. Thank you.
    Unlike the district court’s unsupported analogy between street parades and airport
    protests, Commander Lopez’s testimony is relevant to the governing standard,
    i.e., whether “the restriction on speech is reasonable in light of the purpose
    served by the forum.” Hawkins, 
    170 F.3d at 1287
    ; see also 
    id.
     (“[F]or a court to
    uphold a speech restriction as reasonable, it need not be the most reasonable or
    the only reasonable limitation.” (quotation omitted)). Yet, the district court
    disregarded his testimony without explanation, choosing instead to base its ruling
    on its own beliefs. Because there is no record support for the district court’s
    finding that Defendants can adequately 4 prepare for a protest at DIA with only
    twenty-four hours advance notice every time an exigent circumstance arises, the
    finding is clearly erroneous.
    4
    It is true that Commander Lopez testified that “anything is doable; if we
    have to do it, we have to do it.” But that testimony does not speak to the question
    of whether twenty-four hours provides Defendants with adequate time to
    coordinate an optimal level of security at a busy international airport. The
    reasonableness of Regulation 50 must be evaluated in light of current
    circumstances, including heightened airport security in the wake of the September
    11, 2001 airliner attacks on the World Trade Center and the Pentagon.

    The district court’s flawed analysis and clearly erroneous factual finding
    led it to conclude that Plaintiffs demonstrated a strong likelihood of succeeding
    in their challenge to the lack of an exigency provision in Regulation 50. The
    court abused its discretion in so concluding.
    2. Location
    For the same reasons discussed above, the district court also erred when it
    concluded Plaintiffs showed a strong likelihood of success on their challenge to
    Defendants’ discretion to control the location of permitted speech. Once again,
    the court erroneously injected public forum standards into its analysis.
    McDonnell, 238 F. Supp. 3d at 1301 (referencing public forum cases involving
    “the power of location when conveying a message”).
    3. Signage
    The district court also enjoined Defendants from enforcing restrictions on
    picketing. Regulation 50.02-8 defines picketing as “one or more persons
    marching or stationing themselves in an area in order to communicate their
    position on a political, charitable, or religious issue, or a labor dispute, by
    displaying one or more signs, posters or similar devices.” Id. at 1286.
    Regulation 50.09 prohibits picketing “in all interior areas of the Terminal and
    concourses, in the Restricted Area, and on all vehicular roadways” and further
    states that picketing “shall not be conducted by more than two (2) persons at any
    one location upon the Airport.” Id. Unlike its analysis of the permit process, the
    -17-
    district court did not evaluate this argument by applying standards applicable to
    public forums. Instead, the court concluded Plaintiffs are likely to prevail on a
    challenge to the picketing regulation because “[a]ny argument that the picketing
    ban is reasonable in the context of the Airport is foreclosed by” the Supreme
    Court’s holding in Lee. 5 Id. at 1301. In Lee, the Court upheld a ban on
    solicitation at JFK International Airport but struck down a ban on leafleting,6
    concluding “leafleting does not entail the same kinds of problems presented by
    face-to-face solicitation.” Lee, 
    505 U.S. at 690
     (O’Connor, J., concurring)
    (quotations omitted). Here, the district court stated that picketing is “usually less
    obtrusive” than leafleting and, thus, cannot be banned under Lee. McDonnell,
    238 F. Supp. 3d at 1301.
    The district court’s conclusion that Plaintiffs demonstrate a strong
    likelihood of prevailing on their challenge to the picketing regulation must be
    reversed because it finds no support in the record. When the district court
    compared picketing with leafleting, it found that “[s]ignholding is usually less
    5
    Regulation 50.09 prohibits picketing “in all interior areas of the Terminal
    and concourses, in the Restricted Area, and on all vehicular roadways.”
    McDonnell, 238 F. Supp. 3d at 1286. Thus, it does not completely ban picketing
    at DIA, but it restricts the number and location of picketers in a permitted protest.
    The January 28th protest, which included protestors holding signs, was allowed to
    continue on a plaza outside Jeppesen Terminal that leads to a hotel and a light rail
    station. Id. at 1289.

    In Lee, Justice O’Connor described leafleting as “the repetitive distribution
    of printed or written material.” Int’l Soc’y for Krishna Consciousness, Inc., v.
    Lee, 
    505 U.S. 672
    , 685-86 (1992) (O’Connor, J., concurring).
    -18-
    obtrusive [than leafleting], given that the signholder often stays within an even
    smaller area and conveys his or her message passively to those who walk by and
    notice the sign.” Id. at 1301. Even assuming the district court is correct that
    picketing resembles leafleting because the picketer’s message is conveyed
    passively, picketing is different from leafleting because a passerby is not “free to
    read the message at a later time.” Lee, 
    505 U.S. at 690
     (O’Connor, J.,
    concurring) (quotations omitted) (describing one of the “problems presented by
    face-to-face solicitation” inside an airport terminal as the fact “the recipient
    [must] stop in order to receive the message the speaker wishes to convey”).
    Because of the lack of evidence on the issue, the district court failed to properly
    evaluate whether the restrictions on picketing inside Jeppesen Terminal are
    “reasonable in light of the purpose served by the forum.” Cornelius, 
    473 U.S. at 808
    ; see also Hawkins, 
    170 F.3d at 1290
     (noting the reasonableness inquiry is
    fact-intensive). Accordingly, the court abused its discretion when it concluded
    Plaintiffs met their burden of demonstrating a strong likelihood of prevailing on
    their challenge to the picketing regulation. Kiowa Indian Tribe of Okla. v.
    Hoover, 
    150 F.3d 1163
    , 1165 (10th Cir. 1998) (“An abuse of discretion occurs
    when the district court bases its ruling on an erroneous conclusion of law or relies
    on clearly erroneous fact findings.”).
    On a related issue, the district court enjoined Defendants from enforcing
    the one-foot-by-one-foot signage restriction under Regulation 50.08-12. This
    -19-
    ruling is also reversed because the issue was not addressed in the briefing or
    during the hearing and neither party presented evidence on the matter.
    McDonnell, 238 F. Supp. 3d at 1301-02.
    4. Irreparable Harm, Balance of Harms, and Public Interest
    The district court’s analysis of the three remaining preliminary injunction
    factors of irreparable harm, balance of the harms, and the public interest is
    cursory, but reviewable. Id. at 1305-06. The district court’s analysis was based
    entirely on its conclusion Plaintiffs were likely to prevail on the merits of some
    of their claims. Id. (analyzing the remaining preliminary injunction factors by
    assuming a First Amendment violation). Because we have reversed that ruling,
    the court’s analysis of irreparable harm, balance of harms, and the public interest
    is necessarily flawed and provides no support for the court’s grant of the
    preliminary injunction.
    IV.   Conclusion
    “A preliminary injunction is an extraordinary remedy that is granted only
    when the movant’s right to relief is clear and unequivocal.” First W. Capital
    Mgmt. Co. v. Malamed, 
    874 F.3d 1136
    , 1145 (10th Cir. 2017) (quotations and
    alternations omitted). For the reasons detailed above, we reverse the district
    court’s grant of a preliminary injunction in favor of Plaintiffs on their challenge
    to Regulation 50’s lack of an exigency provision. We also reverse the district
    court’s ruling enjoining Defendants from enforcing Regulation 50’s restrictions
    -20-
    on picketing, including the size of signage, and its ruling enjoining Defendants
    from exercising their discretion to select the location of a permitted protest within
    the airport grounds.
