ABOUT THE FUNDS
- --------------------------------------------------------------------------------
Overview
- ---------------
The American AAdvantage Funds (the "AAdvantage Funds") and the American
AAdvantage Money Market Mileage Fund (the "Mileage Fund") are managed by AMR
Investment Services, Inc. (the "Manager"), a wholly owned subsidiary of AMR
Corporation.
The AAdvantage Funds and the Mileage Fund (collectively, the "Funds") operate
under a master-feeder structure. This means that each Fund seeks its investment
objective by investing all of its investable assets in a corresponding Portfolio
of the AMR Investment Services Trust ("AMR Trust") that has a similar name and
identical investment objective. Throughout this Prospectus, statements regarding
investments by a Fund refer to investments made by its corresponding Portfolio.
For easier reading, the term "Fund" is used throughout the Prospectus to refer
to either a Fund or its Portfolio, unless stated otherwise. See "Master-Feeder
Structure".
Each shareholder of the Money Market Mileage Fund will receive American
Airlines(R) AAdvantage(R) travel awards program ("AAdvantage") miles(1).
AAdvantage miles will be posted monthly to each Shareholder's AAdvantage account
at an annual rate of one mile for every $10 invested in the Fund. See
"AAdvantage Miles".

MONEY MARKET FUND(SM)
- --------------------------------------------------------------------------------
Investment Objective
- -------------------------------
Current income, liquidity and the maintenance of a stable price of $1.00 per
share.
Principal Strategies
- ------------------------------
The Fund invests exclusively in high quality variable or fixed rate, U.S.
dollar-denominated short-term money market instruments. These securities may
include obligations of the U.S. Government, its agencies and instrumentalities;
corporate debt securities, such as commercial paper, master demand notes, loan
participation interests, medium-term notes and funding agreements; Yankeedollar
and Eurodollar bank certificates of deposit, time deposits, and bankers'
acceptances; asset-backed securities; and repurchase agreements involving the
foregoing obligations.
The Fund will only buy securities with the following credit qualities:
- - rated in the highest short-term categories by two rating organizations, such
as "A-1" by Standard & Poor's Corporation and "P-1" by Moody's Investors
Service, Inc.,
- - rated in the highest short-term category by one rating organization if the
securities are rated only by one rating organization, or
- - unrated securities that are determined to be of equivalent quality by the
Manager.
The Fund invests more than 25% of its total assets in obligations issued by the
banking industry. However, for temporary defensive purposes when the Manager
believes that maintaining this concentration may be inconsistent with the best
interests of shareholders, the Fund may not maintain this concentration.
Securities purchased by the Fund generally have remaining maturities of 397 days
or less, although instruments subject to repurchase agreements and certain
variable and floating rate obligations may bear longer final maturities. The
average dollar-weighted maturity of the Fund will not exceed 90 days.

Risk Factors
- -------------------
- - The yield paid by the Fund is subject to changes in interest rates. As a
result, there is risk that a decline in short-term interest rates would lower
its yield and the overall return on your investment.
- - Although the Fund seeks to preserve the value of your investment at $1.00 per
share, it is possible to lose money by investing in the Fund.
- - As with any money market fund, there is the risk that the issuers or
guarantors of securities owned by the Fund will default on the payment of
principal or interest or the obligation to repurchase securities from the
Fund.
Your investment in the Fund is not insured or guaranteed by the U.S. Government
or any financial or government institution.
Investor Profile
- -----------------------
This Fund may be suitable for investors who:
- - seek the preservation of capital and to avoid fluctuations in principal
- - desire regular, monthly income from a highly liquid investment
- - require a short-term vehicle for cash when making long-term investment
decisions
- - seek a rate of return that is potentially higher than certificates of deposit
or savings accounts
Historical Performance
- -----------------------------------
The bar chart below provides an indication of risk by showing how the Fund's
performance has varied from year to year. The Platinum Class of the Fund began
offering its shares on November 7, 1995. However, another class of shares of the
Fund not offered in this prospectus has been offered since September 1, 1987. In
the chart and table below, performance results before November 7, 1995 are for
the older class. Because the other class had lower expenses, its performance was
better than the Platinum Class of the Fund would have realized in the same
period. Past performance is not necessarily

Principal Strategies
- ------------------------------
The Fund invests exclusively in obligations issued or guaranteed by the U.S.
Government, its agencies or instrumentalities and repurchase agreements that are
collateralized by such obligations. Some of these securities are not backed by
the full faith and credit of the U.S. Government. U.S. Government securities
include direct obligations of the U.S. Treasury (such as Treasury bills,
Treasury notes and Treasury bonds).
Securities purchased by the Fund generally have remaining maturities of 397 days
or less, although instruments subject to repurchase agreements and certain
variable and floating rate obligations may bear longer final maturities. The
average dollar-weighted maturity of the Fund will not exceed 90 days.
Risk Factors
- -------------------
- - The yield paid by the Fund is subject to changes in interest rates. As a
result, there is risk that a decline in short-term interest rates would lower
its yield and the overall return on your investment.
- - Although the Fund seeks to preserve the value of your investment at $1.00 per

Airlines, Inc. The Manager was organized in 1986 to provide investment
management, advisory, administrative and asset management consulting services.
As of December 31, 1998, the Manager had approximately $20.4 billion of assets
under management, including approximately $7.2 billion under active management
and $13.2 billion as named fiduciary or financial adviser. Of the total,
approximately $14.5 billion of assets are related to AMR Corporation.
The Manager provides or oversees the provision of all administrative, investment
advisory and portfolio management services to the Funds. The Manager develops
the investment programs for each Fund and serves as the sole investment adviser
to the Funds. As compensation for providing management services, each Fund pays
the Manager an annualized advisory fee that is calculated and accrued daily,
equal to the sum of 0.10% of the net assets of the Fund.
Valuation of Shares
- -------------------------------
The price of each Fund's shares is based on its net asset value ("NAV") per
share. Each Fund's NAV is computed by adding total assets, subtracting all of
the Fund's liabilities, and dividing the result by the total number of shares
outstanding. Securities held by the Funds are valued in accordance with the
amortized cost method, which is designed to enable the Funds to maintain a
stable NAV of $1.00 per share. Debt securities (other than short-term
securities) usually are valued on the basis of prices provided by a pricing
service. In some cases, the price of debt securities is determined using quotes
obtained from brokers.
The NAV of Platinum Class shares will be determined based on a pro rata
allocation of investment income, expenses and total capital gains and losses.
Each Fund's NAV per share is determined as of the close of the New York Stock
Exchange ("Exchange"), generally 4:00 p.m. Eastern time, on each day on which
the Exchange is open for business, with the exception of Columbus Day and
Veteran's Day. The Funds are closed and no NAV is calculated on these days.

Purchase and Redemption of Shares
- ----------------------------------------------------------
Eligibility
- ---------------
Platinum Class shares are offered on a continuous basis at net asset value
through selected financial institutions (such as banks and broker-dealers).
Money Market Mileage Fund shares are offered only to individuals and certain
grantor trusts. Qualified retirement plans (i.e. IRAs, Keogh, profit sharing
plans) and institutional investors are not eligible to invest in the Money
Market Mileage Fund.
Purchase Policies
- --------------------------
No sales charges are assessed on the purchase or sale of Fund shares. Shares
purchased through financial institutions may be subject to transaction fees.
Shares of the Funds are offered and purchase orders accepted until 10:30 a.m.
Central Time (or if earlier, the close of the Exchange) on each day on which the
Exchange is open for trading. In addition, shares are not offered and orders are
not accepted on Columbus Day and Veteran's Day.
If a purchase order is received in good order prior to the Fund's deadline, the
purchase price will be the NAV per share next determined on that day. If a
purchase order is received in good order after the deadline, the purchase price
will be the NAV of the following day that the Fund is open for business. Each
financial institution is responsible for the prompt transmission of purchase
orders for its clients. Checks to purchase shares are accepted subject to
collection at full face value in U.S. funds and must be drawn in U.S. dollars on
a U.S. bank.
Opening an Account
- -------------------------------
A completed, signed application is required to open an account. Financial
institutions may have different procedures for opening an account. Eligible
investors in the Money Market Mileage Fund can enroll in the American Airlines
AAdvantage(R) Program by calling (800) 433-7300. You may request a Fund
application form by calling (800) 973-7977.

Redemption Policies
- ------------------------------
Shares of any Fund may be redeemed by telephone or by mail on any day that the
Fund is open for business by contacting the financial institution through which
Fund shares were purchased. The redemption price will be the NAV next determined
after a redemption order is received in good order. Any questions regarding what
constitutes good order should be directed to the financial institution through
which Fund shares were purchased. Each financial institution is responsible for
the prompt transmission of redemption orders for its clients. Proceeds from
redemptions requested by the following deadlines will generally be wired to
shareholders on the same day.
<TABLE>

</TABLE>
In any event, proceeds from a redemption order for any Fund will be transmitted
to a shareholder by no later than seven days after the receipt of a redemption
request in good order. Delivery of proceeds from shares purchased by check may
be delayed until the check has cleared, which may take up to 15 days. Shares
redeemed through financial intermediaries may be subject to transaction fees.
The Funds reserve the right to suspend redemptions or postpone the date of
payment (i) when the Exchange is closed (other than for customary weekend and
holiday closings); (ii) when trading on the Exchange is restricted; (iii) when
the SEC determines that an emergency exists so that disposal of a Fund's
investments or determination of its NAV is not reasonably practicable; or (iv)
by order of the SEC for protection of the Funds' shareholders.
Although the Funds intend to redeem shares in cash, each Fund reserves the right
to pay the redemption price in whole or in part by a distribution of readily
marketable securities held by the applicable Fund's corresponding Portfolio.
Unpaid dividends credited to an account up to the date of redemption of all
shares generally will be paid at the time of redemption.

General Policies
- ------------------------
The following policies apply to instructions you may provide to the Funds by
telephone:
- - The Funds, their officers, trustees, directors, employees, or agents are not
responsible for the authenticity of instructions provided by telephone, nor
for any loss, liability, cost or expense incurred for acting on them.
- - The Funds employ procedures reasonably designed to confirm that instructions
communicated by telephone are genuine.
- - Due to the volume of calls or other unusual circumstances, telephone
redemptions may be difficult to implement during certain time periods.
The Funds reserve the right to:
- - reject any order for the purchase of shares and to limit or suspend, without
prior notice, the offering of shares,
- - modify or terminate the exchange privilege at any time,
- - limit the number of exchanges between Funds an investor may exercise, and
- - seek reimbursement from you for any related loss incurred if your payment for
the purchase of Fund shares by check does not clear your bank.
Financial institutions may provide varying arrangements for their clients with
respect to the purchase and redemption of Platinum Class shares. Financial
institutions offering Platinum Class shares may impose fees on investors for
checkwriting privileges or, if approved by the Funds, establish variations on
minimum check amounts. Some institutions may arrange for additional privileges
associated with Platinum Class shares, such as a debit card, which may only be
available subject to certain conditions or limitations.
Distribution and Taxes
- -------------------------------------
The Funds distribute most or all of their net earnings in the form of dividends
from net investment income and distributions of realized net capital gains that
are paid to shareholders monthly on the first business day after the month ends.
Unless the account application instructs otherwise, distributions will be
reinvested in additional Fund shares. Usually, dividends (except those paid by
the Municipal Money Market Fund) and distributions of net realized gains are
taxable events.
The Municipal Money Market Fund designates most of its distributions as
"exempt-interest dividends," which may be excluded from gross income. If the
Fund earns taxable income from any of its investments, that income will be
- --------------------------------------------------------------------------------
Prospectus 21 About Your Investment
<PAGE> 22
distributed as a taxable dividend. If the Fund invests in private activity
obligations, shareholders will be required to treat a portion of the interest-
exempt dividends they receive as a "tax preference item" in determining their
liability for federal alternative minimum tax (AMT). Some states exempt from
income tax the interest on their own obligations and on obligations of
governmental agencies and municipalities in the state; accordingly, each year
shareholders will receive tax information on the Fund's exempt-interest income
by state.
This is only a summary of some of the important income tax considerations that
may affect Fund shareholders. Shareholders should consult their tax adviser
regarding specific questions as to the effect of federal, state or local income
taxes on an investment in the Funds.
AAdvantage(R) Miles
- --------------------------------
The AAdvantage program offers its members the opportunity to obtain free
upgrades and travel awards on American Airlines and other AAdvantage airline
participants, as well as upgrades and discounts on car rental and hotel
accommodations. For more information about the AAdvantage program, call American
Airlines at (800) 433-7300.
AAdvantage travel awards ("miles") will be posted monthly in arrears to each
shareholder's AAdvantage account based on the shareholder's average daily
account balance during the previous month. Miles are posted at an annual rate of
one mile per $10 maintained in the Money Market Mileage Fund. Mileage is
calculated on the average daily balance and posted monthly. The average daily
balance is calculated by adding each day's balance and dividing by the number of
days in the month. For example, the average daily balance on an $50,000 account
funded on the 16th day of a month having 30 days (and maintained at that balance
through the end of the month) would be $25,000. Mileage received for that month
would be 208 miles. If the same balance were maintained through the next month,
the average daily balance would be $50,000, and the mileage would be 417 miles
that month and every month the $50,000 investment was maintained in the Money
Market Mileage Fund. These miles appear on subsequent AAdvantage program
statements.
For trust accounts, AAdvantage miles will be posted only in a trustee's
individual name, and not in the name of the trust account. Before investing in
the Money Market Mileage Fund, trustees of the trust account should consult
their own legal and tax advisers as to the tax effect of this arrangement and
whether the arrangement is consistent with their duties as trustees. American
Airlines
- --------------------------------------------------------------------------------
About Your Investment 22 Prospectus
<PAGE> 23
has informed the Money Market Mileage Fund that in administering an AAdvantage
member's AAdvantage account, it shall not be required to distinguish between
AAdvantage miles accumulated by the individual in his/her capacity as trustee to
a trust account from AAdvantage miles accumulated in an individual capacity from
other sources.
The Manager reserves the right to discontinue posting AAdvantage miles or to
change the mileage calculation at any time upon notice to shareholders. American
Airlines may find it necessary to change AAdvantage program rules, regulations,
travel awards and special offers at any time. This means that American Airlines
may initiate changes impacting, for example, participant affiliations, rules for
earning mileage credit, mileage levels and rules for the use of travel awards,
continued availability of travel awards, blackout dates and limited seating for
travel awards, and the features of special offers. American Airlines reserves
the right to end the AAdvantage program with six months' notice. AAdvantage
travel awards, mileage accrual and special offers are subject to governmental
regulations.
ADDITIONAL INFORMATION
- --------------------------------------------------------------------------------
Distribution of Trust Shares
- ----------------------------------------------
The AAdvantage Funds and Mileage Funds have each adopted a Distribution Plan for
the Platinum Class (the "Plans") in accordance with Rule 12b-1 under the
Investment Company Act of 1940 ("1940 Act"), which allow the Funds to pay
distribution and other fees for the sale of Fund shares and for other services
provided to shareholders. In addition, the Mileage Funds' Plan authorizes
expenses incurred in connection with participation in the AAdvantage program.
The Plans provide that each Platinum Class will pay 0.25% per annum of its
average daily net assets to the Manager (or another entity approved by the
applicable Board). Because these fees are paid out of each Fund's assets on an
on-going basis, over time these fees will increase the cost of your investment
and may cost you more than paying other types of sales charges.
- --------------------------------------------------------------------------------
Prospectus 23 Additional Information
<PAGE> 24
Master-Feeder Structure
- --------------------------------------
The Funds operate under a master-feeder structure. This means that each Fund is
a "feeder" fund that invests all of its investable assets in a "master" fund
with the same investment objective. The "master" fund purchases securities for
investment. The master-feeder structure works as follows:
[MASTER-FEEDER STRUCTURE GRAPH]
(graphic follows)
Each Fund can withdraw its investment in its corresponding Portfolio at any time
if the Board determines that it is in the best interest of the Fund and its
shareholders to do so. If this happens, the Fund's assets will be invested
according to the investment policies and restrictions described in this
Prospectus.
Year 2000
- -----------------
The Funds could be affected adversely if the computer systems used by the
Manager, the Funds' other service providers, or companies in which the Funds
invest do not properly process and calculate information that relates to dates
beginning on January 1, 2000 and beyond. Due to the Funds' reliance on various
service providers to perform essential functions, each of the Funds could have
difficulty calculating its NAV, processing orders for share redemptions and
delivering account statements and other information to shareholders. The Manager
has taken steps that it believes are reasonably designed to address the
potential failure of computer systems used by the Manager and the Funds' service
providers to address the Year 2000 issue. There can be no assurance that the
steps taken by the Manager will be sufficient to avoid any adverse impact.
In evaluating current and potential portfolio positions, Year 2000 is one of the
factors that the Manager takes into consideration. The Manager will rely upon
public filings and other statements made by companies regarding their Year 2000
readiness. Issuers in countries outside of the U.S. may not be required to
- --------------------------------------------------------------------------------
Additional Information 24 Prospectus
<PAGE> 25
make the level of disclosure regarding Year 2000 readiness that is required in
the U.S. If the value of a Fund's investment is adversely affected by a Year
2000 problem, the NAV of the Fund may be affected as well.
Financial Highlights
- ---------------------------------
The financial highlights tables are intended to help you understand each Fund's
financial performance for the past five years (or, if shorter, the period of the
Fund's operations). Certain information reflects financial results for a single
share of the Fund's Platinum Class. The total returns in the table represent the
rate that an investor would have earned (or lost) on an investment in the Fund
(assuming reinvestment of all dividends and distributions). Each Fund's
highlights were audited by Ernst & Young LLP, independent auditors. More
financial information about the Funds is found in their Annual Report, which you
may obtain upon request.
