    Judge.
    Before HATCHETT, Circuit Judge, HENDERSON, Senior Circuit Judge,

    PER CURIAM:
    This is an interlocutory appeal from the order of the United
    *
    Honorable Richard H. Mills, U.S. District Judge for the
    Central District of Illinois, sitting by designation.
    States District Court for the Northern District of Georgia denying
    the plaintiffs' motion for class certification and dismissing a
    pendent state law claim for lack of jurisdiction.1   We affirm.
    I. BACKGROUND
    The plaintiffs are former employees of Delta Air Lines, Inc.
    ("Delta"), who retired between July 23, 1992 and January 1, 1993.
    On May 16, 1994, they commenced this action against Delta and
    various Delta officials based upon alleged violations of the
    Employment Retirement Income Security Act, 
    29 U.S.C. §§ 1001
          et
    seq. ("ERISA"), and also asserting a state law breach of contract
    cause of action.   On June 3, 1994, they filed an amended complaint
    to add certain defendants.    According to the allegations of the
    complaint,2 the facts giving rise to the lawsuit are as follows.3
    On July 23, 1992, Delta announced impending changes in the
    medical insurance benefits plan provided by the company for its
    employees and retirees.4     Employees were told that those who
    1
    This court granted the plaintiffs' petition for
    interlocutory review pursuant to 
    28 U.S.C. § 1292
    (b), which
    permits appeals to be taken in civil cases from decisions not
    otherwise appealable when the district court certifies that the
    "order involves a controlling question of law as to which there
    is substantial ground for difference of opinion and that an
    immediate appeal from the order may materially advance the
    ultimate termination of the litigation." 
    28 U.S.C. § 1292
    (b).
    2
    We refer to the amended complaint as the complaint.
    3
    At this preliminary stage of the case and for purposes of
    this appeal, we must treat the allegations of the complaint as
    true.
    4
    A notice issued to "All Members of the Delta Family" stated
    that, due to adverse economic forces and to avoid "downsizing,"
    it was necessary for the airline to substantially and permanently
    reduce its costs, which, among other things, would require
    revision of the company-provided medical and dental benefits
    package. (R2-20, Exhibit I).
    retired after January 1, 1993 would receive reduced benefits and be
    required to pay higher premiums than persons who retired prior to
    that date.    In subsequent weeks, the company disseminated further
    information,    both   orally   and   in   writing,   which   stated    that
    individuals who retired on or before January 1, 1993, would be
    "grandfathered" with respect to their current medical benefits,
    meaning, they would be entitled to the same level of coverage
    throughout the course of their retirement and would not be affected
    by any future changes in the medical insurance plan offered by the
    airline.    In addition, Delta assured its employees that it did not
    intend at that time to offer any package of enhanced retirement
    incentives in the future. The latter declarations were made orally
    during retirement planning seminars conducted by the company and
    "in numerous conversations with potential Delta retirees."             (R1-3
    at ¶ 45).
    The complaint further alleged that the plaintiffs chose their
    retirement dates in reliance on Delta's promises that their level
    of medical coverage and premiums would remain constant throughout
    their retirement and that no improved retirement package was in the
    planning stage at the time they made their decision.           After they
    retired, however, the company reduced the level of their medical
    benefits and required them to pay higher premiums for coverage.
    Also, contrary to the statements made denying a plan to offer an
    enhanced benefits package in the future, retirement terms more
    favorable than those extended to the plaintiffs were contemplated
    by the airline prior to January 1, 1993 and in fact were offered to
    certain eligible employees on August 23, 1993 (hereinafter referred
    to as the "Special Retirement Plan").
    These allegations formed the basis for the first four counts
    of the complaint.        Count I urged that, when the plaintiffs retired
    on or before January 1, 1993, they entered into a bilateral
    contract with Delta, enforceable under ERISA, which mandated that
    the company continue to provide the same medical benefits package
    to the plaintiffs throughout their retirement years.                           Count II
    asserted    that    by    making   false      assurances     to    the    plaintiffs
    regarding    the    continuation      of    the   terms     of    their   retirement
    benefits    and    by    denying   the     intention    to   offer       the    Special
    Retirement Plan in the future, Delta breached its fiduciary duty to
    the plaintiffs in violation of ERISA. Count III charged that Delta
    fraudulently induced the plaintiffs to retire on or before January
    1, 1993 for the purpose of preventing their participation in the
    Special    Retirement      Plan.      Count    IV    claimed      that    by    falsely
    informing the plaintiffs that no better retirement package would be
    forthcoming after January 1, 1993, and then extending such a
    package to subsequent retirees, Delta unlawfully discriminated
    against certain benefits plan participants in favor of others,
    contrary to ERISA.
    In addition to the ERISA causes of action contained in Counts
    I through IV, Count V of the complaint alleged a suit for breach of
    contract    under   Georgia    law.        This     claim   was    predicated      upon
    allegations that Delta made repeated promises to the plaintiffs
    during their employment that retirees who were at least fifty-two
    years' old and who had worked for the airline for at least ten
    years would be entitled to certain flying privileges throughout
    their retirement.             However, on October 26, 1993, the company
    eliminated flight privileges for any retiree who had accepted
    employment with another airline or affiliate.
    On       August    12,      1994,    the     plaintiffs     moved   for    class
    certification pursuant to Fed.R.Civ.P. 23.                 In a brief in support
    of the motion, the plaintiffs identified the putative class as over
    1,800 "former employees of Delta Air Lines, Inc., who retired from
    employment at Delta Air Lines between the dates of July 23, 1992
    and January 1, 1993, inclusive."                    (R1-11, Brief at 2).          The
    plaintiffs alleged that the causes of action set forth in Counts I
    through V of the complaint could best be pursued in the form of a
    class action because, inter alia, they involved common issues of
    law and fact and the claims of the class representatives were
    typical of those of the class as a whole.
    Thereafter, the defendants moved to dismiss Count V of the
    complaint for lack of subject matter jurisdiction on the ground
    that it was unrelated to the federal ERISA claims asserted in
    Counts    I    through      IV   and     lacked    the   requisite    diversity    of
    citizenship.         The defendants also opposed class certification,
    contending in part that the ERISA claims were not amenable to
    class-wide proof because they turned on each retiree's individual
    reliance on the alleged assurances made by Delta. Furthermore, the
    defendants argued, the requirements of commonality and typicality
    necessary for class certification were not met because the claims
    depended,      all     or   in   part,     upon    a   variety   of   alleged    oral
    representations, thereby necessitating proof of the particular
    statements made to each retiree.5   The defendants conceded that "if
    Plaintiff's claims were based on uniform written documents received
    and relied on by the entire class, commonality and typicality could
    be present."   (R2-16 at 36).   They maintained, however, that the
    plaintiffs failed to carry their burden of proof on this score
    because they offered no evidence that Delta ever issued such
    uniform written assurances.
    The plaintiffs then filed a reply to the motion to dismiss
    Count V and to the defendants' opposition to class certification.
    In support of the latter issue, the plaintiffs submitted, inter
    alia, copies of a newsletter disseminated by Delta to its employees
    and several intracompany memorandums, all of which discussed the
    changes in the medical benefits plan effective January 1, 1993.6
    In an order dated November 4, 1994, the district court granted
    the defendants' motion to dismiss Count V for lack of jurisdiction
    and denied the plaintiffs' motion for class certification.     With
    respect to Count V, the court found that the requirements for
    supplemental jurisdiction under 
    28 U.S.C. § 1367
     were not present
    because the state law claim alleged therein did not sufficiently
    5
    According to the allegations of the complaint, Count I was
    based upon oral and written representations. The claims
    involving the Special Retirement Plan resulted solely from
    alleged oral promises.
    6
    The evidence submitted by the plaintiffs included company
    memorandums dated both before and after January 1, 1993. (See
    generally R2-20, Exhibits). Only the newsletter, which was dated
    August 27, 1992, and those memorandums issued prior to January 1,
    1993 could have affected the timing of the plaintiffs'
    retirement. An affidavit of one of the plaintiffs, Felton E.
    Hudson, was also proffered. It states that "[s]uch memos were
    posted on company bulletin boards." (Id. at Exhibit B, ¶ 6). No
    objections to the inclusion of this evidence in the record were
    made by Delta. We presume that it is properly before us.
    involve the same facts, occurrences, witnesses or evidence as the
    federal ERISA claims and it was separately maintainable from the
    ERISA counts.     On the issue of class certification of the ERISA
    causes of action, the court found that the plaintiffs failed to
    furnish proof rising to the level imposed by federal law which
    would demonstrate commonality and typicality.       In particular, the
    court stated that the plaintiffs
    have not shown that the questions of fact in each affected
    retiree's case are common to any other retiree's case.
    According to the plaintiffs, Delta made the representations
    that are at issue in this case orally, during several
    retirement planning seminars, and in writing, in various
    mailouts and fliers posted on bulletin boards.     Plaintiffs
    must show not only whether each retiree was aware of these
    representations, but more importantly, the extent to which
    each retiree relied on the alleged representations in making
    his or her retirement decision. These are factual issues that
    must be resolved independently for each retiree.
    (R2-24 at 8).
    On November 21, 1994, the plaintiffs moved for reconsideration
    of the district court's order, or in the alternative, for the
    certification    necessary   to   seek   an   interlocutory   appeal   in
    accordance with 
    28 U.S.C. § 1292
    (b).      See supra note 2.    The court
    denied the request for reconsideration, but did issue the § 1292(b)
    certification.    This court subsequently permitted the appeal.7
    II. STANDARD OF REVIEW
    The district court's dismissal of Count V of the complaint
    for lack of subject matter jurisdiction is a question of law which
    7
    When the district court certifies that interlocutory review
    of an order is warranted, the court of appeals may, in its
    discretion, permit an appeal to be taken if application is made
    to it within ten days after entry of the district court's
    certification.

    certification under an abuse of discretion standard. Washington v.

    , 1566
    (11th Cir.1987).
    III. DISCUSSION
    A. Dismissal of Count V.
    We first address the district court's dismissal of Count V
    for lack of subject matter jurisdiction.             There is no question in
    this case that diversity of citizenship does not exist, thus,
    subject matter jurisdiction over the state law allegations in Count
    V   depends   upon   the   existence   of     that   aspect    of     supplemental
    jurisdiction formerly known as pendent claim jurisdiction.                      See
    Palmer v. Hospital Auth. of Randolph County, 
    22 F.3d 1559
    , 1566
    (11th Cir.1994).       The presence of supplemental jurisdiction is
    governed by 
    28 U.S.C. § 1367
    .           Subsection (a) of that statute
    defines the power of the federal courts to hear supplemental
    claims.     Palmer, 
    22 F.3d at 1566
    .          It provides in relevant part
    that
    in any civil action of which the district courts have original
    jurisdiction, the district courts shall have supplemental
    jurisdiction over all other claims that are so related to
    claims in the action within such original jurisdiction that
    they form part of the same case or controversy under Article
    III of the United States Constitution.
    
    28 U.S.C. § 1367
    (a).       The district court had original jurisdiction
    (in this case, federal question jurisdiction) over the ERISA
    counts. The court's power to adjudicate Count V therefore turns on
    whether the state law cause of action alleged therein is so related
    to an ERISA ground that they form part of the same case or
    controversy.     In deciding whether a state law claim is part of the
    same case or controversy as a federal issue, we look to whether the
    claims arise from the same facts, or involve similar occurrences,
    witnesses or evidence.     Palmer, 
    22 F.3d at 1566
    .
    We agree with the district court that Count V of the
    complaint does not arise from the same case or controversy as the
    ERISA   causes   of   action.   The   record   shows   that   the   flight
    privileges at issue in Count V were not part of an ERISA benefits
    plan and were administered by a different department of Delta.
    Moreover, the alleged facts underlying Count V are completely
    unrelated to the allegations in support of the ERISA claims.          The
    only factor they share in common is that the airline's decisions
    with respect to ERISA benefits and flight benefits affected certain
    retirees.    This does not provide a sufficient nexus between the
    federal and state causes to support supplemental jurisdiction.          We
    consequently affirm the dismissal of Count V.          In so doing, we
    necessarily find that the issue of class certification as to Count
    V is moot.
    B. Denial of Class Certification.
    Next, we consider the district court's denial of class
    treatment of Counts I, II, III and IV, the ERISA grounds.            Class
    certification is governed by Fed.R.Civ.P. 23.      Rule 23 permits the
    maintenance of a class action when (1) the class is so numerous
    that joinder of all of its members is impracticable, (2) questions
    of law or fact common to the class are present, (3) the claims or
    defenses of the representative parties are typical of the claims or
    defenses of the class and (4) the representative parties will
    sufficiently protect the interests of the class.            Fed.R.Civ.P.
    23(a).8     The burden of proving these prerequisites is on the
    representative    party   or   parties   seeking   class   certification.
    Gilchrist v. Bolger, 
    733 F.2d 1551
    , 1556 (11th Cir.1984);          Nelson
    v. United States Steel Corp., 
    709 F.2d 675
    , 678-79 (11th Cir.1983).
    As stated earlier, the district court's decision to deny
    class certification was based upon the absence of commonality and
    typicality.    These factors provide the necessary link between the
    class representatives and the class members.        Washington, 959 F.2d
    at 1569 n. 8.    Although the issues of commonality and typicality
    are separate inquiries, proof of each also "tend[s] to merge." Id.
    The plaintiffs contend that commonality and typicality are
    present with respect to Count I because, although they and the
    putative class members received the alleged assurances through
    different media and from different sources, the airline issued a
    8
    If the requirements of Fed.R.Civ.P. 23(a) are met, the
    district court must go further and determine whether the facts
    before the court satisfy Fed.R.Civ.P. 23(b). That subsection
    provides that class actions are appropriate only when (1) the
    prosecution of separate actions would create a risk of
    inconsistent verdicts or where individual adjudications would, as
    a practical matter, be dispositive of the interests of class
    members who are nonparties; or (2) the party opposing the class
    has acted or refused to act on grounds generally applicable to
    the putative class such that declaratory or injunctive relief
    with respect to the class as a whole would be appropriate; or
    (3) questions of law or fact common to members of the class
    predominate over issues affecting individual members and class
    adjudication is preferable to other methods of litigation for
    purposes of a fair and efficient resolution of the controversy.
    Because the district court found that the Rule 23(a)
    prerequisites of commonality and typicality were not present, it
    did not reach the Rule 23(b) issue. Our review on appeal is
    therefore confined to the district court's subsection (a)
    determination.
    uniform message to all employees concerning the terms of their
    future medical benefits plan, which depended on their retirement on
    or before January 1, 1993.        Likewise, they claim, Delta issued
    identical   information    to   all   members   of   the   putative   class
    concerning the Special Retirement Plan, that is, that no such plan
    was contemplated for a later date.
    In response, the defendants essentially argue that the ERISA
    claims have no merit.     They maintain that Delta reserved the right
    to amend or discontinue the plaintiffs' medical benefits at any
    time.9   Thus, the defendants insist that the plaintiffs cannot
    prove, class-wide or otherwise, the formation of the purported
    bilateral contract alleged in Count I. In addition, the defendants
    reiterate that evidence of individual reliance on a variety of
    purported oral representations is necessary with respect to all of
    the ERISA counts and state that, consequently, each plaintiff's
    claims must be determined on a case-by-case basis.
    We stress initially that the merits of the plaintiffs' claims
    are not before us.      See Eisen v. Carlisle & Jacquelin, 
    417 U.S. 156
    , 178, 
    94 S.Ct. 2140
    , 2153, 
    40 L.Ed.2d 732
    , 749 (1974) (quoting
    Miller v. Mackey Int'l, 
    452 F.2d 424
    , 427 (5th Cir.1971) (" "In
    determining the propriety of a class action, the question is not
    9
    In support of this assertion the defendants refer to a
    statement contained in a supplement to Delta's benefits handbook,
    which described changes in post-retirement medical and dental
    benefits effective January 1, 1992. The supplement states, "[a]s
    always, Delta reserves the right to change, modify, amend or
    discontinue the benefits described in this supplement of the
    Benefits Handbook at any time." (Appendix of Appellees, Tab A,
    Exhibit 2; see also 
    id.
     at Tab J, Exhibit 77). This evidence
    was not made a part of the record in the district court.
    Consequently, we do not consider it on appeal.
    whether the plaintiff or plaintiffs have stated a cause of action
    or will prevail on the merits, but rather whether the requirements
    of Rule 23 are met.' ").   Nevertheless, "evidence relevant to the
    commonality requirement is often intertwined with the merits."
    Nelson, 709 F.2d at 679. Accordingly, it sometimes is necessary to
    "to probe behind the pleadings before coming to rest on the
    certification question."    General Tel. Co. of the Southwest v.
    Falcon, 
    457 U.S. 147
    , 160, 
    102 S.Ct. 2364
    , 2372, 
    72 L.Ed.2d 740
    ,
    752 (1982).
    The issue of commonality with respect to the Count I contract
    claim is fundamentally different than the commonality that must be
    shown to support class certification of the Special Retirement Plan
    allegations described in Counts II through IV.     We find that the
    claims relating to the Special Retirement Plan are not susceptible
    to class-wide proof.   Even if the plaintiffs are able to prove that
    Delta disseminated a false and uniform message to all potential
    retirees that no such plan was in the works at the time they made
    their decision to retire, they would also have to show that all
    members of the class would have deferred their retirement in the
    hope that they would be eligible for the Special Retirement Plan to
    be offered in the future.10 This sort of decision would necessarily
    10
    The evidence contained in the record regarding the Special
    Retirement Plan discloses that it was offered only to a select
    group of employees who were at least fifty-two years' old on
    November 1, 1993 and who worked in particular departments of the
    airline targeted for downsizing. Participation was also limited
    to a certain number of persons in those departments to fit the
    business needs of the airline. (R2-20, Exhibits E, F). There
    was no guarantee that persons eligible for the program would be
    allowed to enroll. If requests to retire under the plan exceeded
    availability, acceptance was based upon seniority. (Id. at
    Exhibit F). It is most unlikely that all members of the putative
    have been highly individualized for each potential retiree.
    On the other hand, the merits of the Count I contract cause
    depend    simply   on   evidence   of    the     formation   of   the   bilateral
    contract alleged therein.        This will require proof of written plan
    documents which notified the putative class that the terms of their
    medical    benefits     plan   would    remain    constant   throughout    their
    retirement if they retired on or before January 1, 1993.
    ERISA requires that welfare benefit plans be governed by
    written plan documents which are to be prepared and filed in
    compliance   with    ERISA's    reporting   and    disclosure
    requirements.... Accordingly, any retiree's right to lifetime
    medical benefits at a particular cost can only be found if it
    is established by contract under the terms of the
    ERISA-governed benefit plan document.

     (1991).             This type of claim seems, on
    the surface, to be amenable to class-wide proof.              So far, however,
    the plaintiffs have failed to demonstrate the existence of such
    written plan documents.11       The plaintiffs' reliance on the alleged
    uniform oral statements guaranteeing the same level of medical
    benefits throughout their retirement is of no help because "there
    [is] no federal common law right to promissory estoppel under ERISA
    in cases involving oral amendments to or modifications of employee
    class were eligible to participate in the program or would have
    delayed their retirement on the chance that they might be
    selected. In any event, the plaintiffs made no showing on this
    issue.

    plans governed by ERISA."12

    .
    In Alday, this court stated in dicta that ERISA fiduciaries
    might not be insulated from liability on the basis of the formal
    written plan documents where contradictory and fraudulent promises
    are made in informal communications for the purpose of deceiving
    employees with respect to their benefits.   
    Id.
     at 666 n. 15.   We
    voice no opinion as to whether the plaintiffs could state a claim
    under such circumstances. Even if they could, none of the evidence
    of record to date, which consists solely of informal company
    communications, supports the plaintiffs' allegations that they were
    assured that the terms of their medical coverage would never
    change.13   With this record as our only source of information, we
    can find no abuse of discretion by the district court in denying

    A federal common law claim of equitable estoppel may come
    into play based upon oral interpretations of ambiguous ERISA plan
    documents. Alday, 906 F.2d at 666; Kane v. Aetna Life Ins., 
    893 F.2d 1283
    , 1285-86 (11th Cir.), cert. denied, 
    498 U.S. 890
    , 
    111 S.Ct. 232
    , 
    112 L.Ed.2d 192
     (1990). "However, estoppel is not
    available either for oral modifications (as opposed to
    interpretations) or when the written plan is unambiguous." Glass
    v. United of Omaha Life Ins. Co., 
    33 F.3d 1341
    , 1347 (11th
    Cir.1994). The plaintiffs do not allege in this case that the
    controlling ERISA plan documents were ambiguous.

    The newsletter defined "grandfathered" persons as
    "includ[ing] those individuals who were Delta employees as of
    August 31, 1991 and were age 52 or older as of January 1, 1992."
    (R2-20, Exhibit H). It also stated that "[i]f you elect to
    retire early prior to age 62 on January 1, 1993, the early
    retirement medical and dental contribution will not apply.
    However, the service related contribution may apply if you were
    not part of the grandfathered group." 
    Id.
     It is not clear from
    this language exactly what it meant to be "grandfathered."
    Moreover, although the evidence indicates that Delta told
    potential retirees that certain employee contributions would be
    waived for persons in the "grandfathered" group who retired on or
    before January 1, 1993, nothing in the record supports the
    plaintiffs' claims that they were also told that the particular
    type of medical benefits included in the ERISA plan would be
    provided in perpetuity.
    class certification as to Count I of the complaint.
    Of course, if, through further proceedings, the plaintiffs are
    able        to    clarify   and   better   support   the   need   for   class
    certification, the district court remains free to revisit the
    issue.14         The determination of whether a class should be certified
    should be made "[a]s soon as practicable after the commencement of
    an action."          Fed.R.Civ.P. 23(c)(1).   Additional discovery on the
    issue and a hearing may be helpful.15          See Washington, 959 F.2d at
    1570-71.         We leave any further development of the class treatment
    issue with respect to Count I to the sound discretion of the
    district court.16           We simply hold that, at this stage of the
    14
    For example, the plaintiffs may yet be able to produce
    written plan documents in support of Count I. We caution,
    however, that the documentation currently in the record indicates
    that Delta made certain differentiations among various groups of
    retirees depending upon an employee's age at retirement, years of
    service and whether some of that service was with another
    airline. Thus, even if class certification were appropriate, it
    might be necessary to define and provide for various subclasses.
    But, we also note that at this point the plaintiffs' case appears
    to be based solely upon a theory of promissory estoppel, which is
    not cognizable under ERISA. Alday, 906 F.2d at 666. If the
    plaintiffs are unable to state a claim for relief, any question
    as to class certification will be moot. See id. at 667.

    Although a hearing is not required prior to           granting or
    denying a motion for class certification, Grayson           v. K Mart
    Corp., 
    79 F.3d 1086
    , 1099 (11th Cir.1996), such a           procedure may,
    in an appropriate case, aid the court in deciding           the issue.
    16
    Although the issue of class certification should be
    resolved in the early stages of a case if possible, prior
    discovery is often necessary to sufficiently define the proper
    scope of an alleged class or subclass. Here, the plaintiffs
    moved for class treatment prior to conducting any discovery,
    traveling solely on the broad allegations of the complaint. Such
    an approach may be acceptable in some cases, but this is not one
    of them. Because the entitlement to ERISA benefits is controlled
    by formal plan documents, the analysis of any claim arising from
    the alleged failure to comply with an ERISA plan must begin with
    an examination of those documents, which will also define the
    class or classes of persons governed thereby. The record in the
    proceedings, the district court did not abuse its discretion in
    denying class certification on the record before us.
    IV. CONCLUSION
    In accordance with the foregoing, we AFFIRM the dismissal of
    Count V for lack of subject matter jurisdiction, we AFFIRM the
    denial of class certification with respect to Counts I, II, III and
    IV and we REMAND the case to the district court for further
    proceedings.
    present case shows that discovery began on August 17, 1994 and
    continued until March 22, 1995, when it was stayed by the
    district court pending the resolution of this appeal. The
    plaintiffs failed to make the pertinent ERISA plan documents a
    part of the record during this time. By suggesting that the
    district court may, in its discretion, reopen the class
    certification issue after further development of the case, we do
    not mean to imply that the court should do so.
