ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

         The securities were acquired pursuant to Tender Agreements dated as of
February 14, 2001 (the "Tender Agreements") between Travel Services and each of
the stockholders of SierraCities listed on Schedule II hereto (the
"Stockholders"). The Tender Agreements were entered into in connection with and
as a condition to the execution and delivery of the Merger Agreement (as defined
below). Travel Services did not pay additional consideration to the Stockholders
in connection with the execution and delivery of the Tender Agreements.

<PAGE>   5
         References to, and descriptions of, the Offer (as defined below), the
Merger (as defined below), the Merger Agreement and the Tender Agreements as set
forth herein are qualified in their entirety by reference to the copies of the
Merger Agreement and the Tender Agreements, respectively, included as Exhibits
to this Schedule 13D, and are incorporated herein in their entirety where such
references and descriptions appear.

ITEM 4.  PURPOSE OF TRANSACTION

         (a) - (b) Pursuant to an Agreement and Plan of Merger dated as of
February 14, 2001 (the "Merger Agreement"), among Travel Services, AMTRS Corp.,
a newly formed Delaware corporation and wholly owned subsidiary of Travel
Services ("AMTRS"), and SierraCities, and subject to the conditions set forth
therein, AMTRS will commence a tender offer (the "Offer") to purchase all of the
outstanding shares of Common Stock of SierraCities at a purchase price of $5.68
per share (such price, or such higher price as may be paid in the Offer, being
referred to herein as the "Per Share Amount"), net to the seller in cash,
without interest thereon. Following the completion of the Offer, AMTRS will
merge with and into SierraCities and SierraCities will become a wholly owned
subsidiary of Travel Services (such events constituting the "Merger"). Once the
Merger is consummated, AMTRS will cease to exist as a separate corporation and
all of the business, assets, liabilities and obligations of AMTRS will be merged
into SierraCities with SierraCities remaining as the surviving corporation (the
"Surviving Corporation").

                  As a result of the Merger, each outstanding share of Common
Stock, other than shares owned by SierraCities, Travel Services, AMTRS, any
subsidiary of SierraCities or Travel Services and, if applicable, stockholders
exercising appraisal rights, will be converted into the right to receive the Per
Share Amount in cash payable to the holder thereof, without interest (the
"Merger Consideration"). Pursuant to the Merger Agreement, each outstanding
option to purchase Common Stock shall be canceled in exchange for a single lump
sum cash payment (less any applicable tax withholdings) payable by the Surviving
Corporation, equal to the amount, if any, by which the Merger Consideration
exceeds the per share exercise price of such SierraCities stock option,
multiplied by the number of shares then subject to such SierraCities stock
option.

                  The Stockholders have, by executing the Tender Agreements,
agreed to tender in the Offer the 3,817,057 shares of Common Stock beneficially
owned by them (the "Shares"). The Shares constitute approximately 20.1% of the
total outstanding shares of Common Stock as of February 12, 2001. In addition,
as part of the Tender Agreements, each Stockholder has granted to Travel
Services an irrevocable proxy to vote or consent in writing, at every
SierraCities stockholders meeting and on every action or approval by written
consent instead of a meeting, (i) in favor of the approval and adoption of the
Merger Agreement and the approval of the Merger, and in favor of each of the
other actions contemplated by the Merger Agreement, (ii) against any proposal
for any recapitalization, merger, sale of assets or other business combination
between SierraCities and any person or entity (other than the Merger) and
(iii) against any action or agreement that would result in a breach of any
covenant, representation or warranty or would result in any obligation or
agreement of SierraCities under the Merger Agreement not being fulfilled or
would result in SierraCities being required to pay to Parent or Purchaser the
termination fee described in the Merger Agreement.

                   The Tender Agreements terminate upon the earliest of the
following: (i) the date upon which the Merger Agreement is terminated; (ii) the
date upon which the Merger is effected; (iii) the date upon which all of the
Stockholders' now owned or hereafter acquired shares of SierraCities' Common
<PAGE>   6
Stock are purchased by Travel Services or AMTRS pursuant to the Offer and
(iv) the date on which the Offer terminates without the prompt purchase of
Common Stock thereunder.

                   The purpose of the transactions under the Tender Agreements
are to assist Travel Services and SierraCities in consummating the transactions
contemplated under the Merger Agreement.

         (c)      Not applicable.

         (d)      Upon the acceptance for payment of any shares of Common Stock
pursuant to the Offer, Travel Services will be entitled to designate a number of
directors of SierraCities, rounded up to the next whole number, that equals the
product of (i) the total number of directors on SierraCities' board of directors
multiplied by (ii) the percentage that the number of shares beneficially owned
by Travel Services or AMTRS following the acceptance for payment of shares
pursuant to the offer bears to the total number of shares outstanding. Until the
Merger has become effective, SierraCities' board of directors will consist of at
least two members who were directors of SierraCities prior to the consummation
of the Offer. Upon consummation of the Merger, the directors of AMTRS shall
become the directors of the Surviving Corporation. The initial officers of the
Surviving Corporation shall be the officers of AMTRS, until their respective
successors are duly elected or appointed and qualified.

         (e)      Neither of the Reporting Persons currently has any plan or
proposal which relates to, or may result in, any of the matters listed in Item
4(e) of Schedule 13D other than (i) the cancellation and payment of SierraCities
options as contemplated by the Merger Agreement and (ii) the change in the
number of outstanding shares of Common Stock as contemplated by the Merger
Agreement.

         (f)      Not applicable.

         (g)      Upon consummation of the Merger, the Certificate of
Incorporation of AMTRS, as in effect immediately prior to the Merger, shall
become the Certificate of Incorporation of the Surviving Corporation until
thereafter amended as provided by Delaware corporate law and such Certificate of
Incorporation. The name of the Surviving Corporation will be SierraCities.com
Inc. Upon consummation of the Merger, the Bylaws of AMTRS, as in effect
immediately prior to the Merger, shall be the Bylaws of the Surviving
Corporation until thereafter amended.

         (h)      The shares are currently traded on the Nasdaq National Market.
Following the consummation of the Merger, the shares will no longer be listed on
Nasdaq.

         (i)      Upon consummation of the Merger, the Common Stock will become
eligible for termination of registration pursuant to Section 12(g)(4) of the
Exchange Act.

         (j)      Other than as described above, neither of the Reporting
Persons currently has any plan or proposal which relates to, or may result in,
any of the matters listed in Items 4(a) - (i) of Schedule 13D. However, the
Reporting Persons will continue to review the business of SierraCities and may
in the future propose that SierraCities take one or more of such actions.

         References to, and descriptions of, the Merger Agreement and the Tender
Agreements as set forth above in this Item 4 are qualified in their entirety by
reference to the copies of the Merger Agreement and the Tender Agreements
included as Exhibits to this Schedule 13D, and incorporated in this Item 4 in
their entirety where such references and descriptions appear.
<PAGE>   7
ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

         (a) - (b) As a result of the Tender Agreements, Travel Services may be
deemed to be the beneficial owner of 3,817,057 shares of Common Stock. Those
shares of Common Stock constitute approximately 20.1% of the issued and
outstanding shares of Common Stock, based on the number of shares of Common
Stock outstanding as of February 12, 2001 (as represented by SierraCities in the
Merger Agreement discussed in Items 3 and 4). Travel Services may be deemed to
have the shared power to vote the shares of Common Stock with respect to those
matters described above. However, Travel Services (i) is not entitled to any
rights as a stockholder of SierraCities as to the shares of Common Stock and
(ii) disclaims any beneficial ownership of the shares of Common Stock. Travel
Services does not have the power to dispose of the shares of Common Stock.
Pursuant to the Tender Agreements, Travel Services has the right to vote, with
respect to those matters discussed above, any additional shares of Common Stock
acquired by any Stockholder (whether by purchase, upon conversion of options or
convertible securities or otherwise) after the date of the Tender Agreements.

         (c)      Except as described above, neither of the Reporting Persons
nor, to the best of their knowledge, any of the persons listed in Schedule I
hereto, effected any transactions in the class of securities reported during the
past 60 days.

         (d)      To the knowledge of the Reporting Persons, no other person has
the right to receive or the power to direct the receipt of dividends from, or
the proceeds from the sale of, the securities of SierraCities.

         (e)      Not applicable.

ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
         TO SECURITIES OF THE ISSUER

         Other than the Merger Agreement and the exhibits thereto, and the
Tender Agreements, to the knowledge of the Reporting Persons, there are no
contracts, arrangements, understandings or relationships among the persons named
in Item 2 and between such persons and any person with respect to any securities
of SierraCities, including but not limited to transfer or voting of any of the
securities, finder's fees, joint ventures, loan or option arrangement, puts or
calls, guarantees of profits, division of profits or loss, or the giving or
withholding of proxies.
