Cancun airport and a 22.54% increase at Villahermosa airport.

The 17.29% year-over-year increase in international passenger traffic in the
fourth quarter of 2003 was principally due to a 17.49% growth in passenger

year 2003 increased by 10.85%, 10.35% and 11.21%, respectively.

Consolidated Results for 4Q03
--------------------------------------------------------------------------------

Total revenues for 4Q03 reached Ps.346.7 million, representing a year-over-year
increase of 18.04%. This was mainly due to:

o    An increase of 14.23% in revenues from aeronautical services, principally
     as a result of the above-mentioned growth in passenger traffic; and,

o    An increase of 32.74% in revenues from non-aeronautical services,
     principally driven by the 39.71% year-over-year improvement in commercial
     revenues.

ASUR classifies revenues from the following activities as commercial revenues:
duty free sales, car rentals, retail sales, banking and currency exchange
services, advertising space rentals, teleservices, non-permanent ground
transportation, food and beverage and parking lot operations.

In 4Q03 commercial revenues improved by 39.71% when compared to 4Q02, mainly due
to:

o    A 27.98% increase in duty-free revenues, primarily as a result of the
     increase in international passenger traffic and an improved product mix;

o    An increase of 62.36% in food and beverage revenues, primarily as a result
     of the growth in passenger traffic and the opening of restaurants and bars
     in Cancun airport, in particular the opening of Margarita Ville in December
     2003. The increase in food and beverage revenues also resulted from the
     opening of new food and beverage stores throughout the year, as detailed
     below:

o    A 34.22% increase in retail revenues, principally due to higher passenger
     traffic and the opening of new stores. During the quarter, the following
     stores were opened: Portafolio, a clothing store at Merida airport on
     October 2003, a convenience store at Cancun airport on November 2003 and a
     jewelry store at Huatulco airport on November 2003. The increase in retail
     revenues for the quarter was also due to the following store openings that
     took place earlier in 2003:

o    A 109.28% increase in advertising revenues, resulting from the creation of
     additional space for advertising and revenues relating to the distribution
     of print advertising at Cancun airport.

o    A 71.62% increase in revenue from banking and currency exchange services,
     primarily resulting from American Express becoming fully operational after
     the completion of the remodeling of Terminal 2 at the Cancun airport.

Total operating costs and expenses for 4Q03 increased year-over-year by 6.50%,
mainly as a result of:

o    A 1.44% decline in costs of services mainly as a result of a reduction in
     travel expenses of ASUR's personnel.

o    A 34.70% increase in administrative expenses primarily as a result of the
     development of the 2004-2018 master development plan and the presentation
     of investment projects for the Cancun airport.

o    A 25.48% increase in the cost of technical assistance, mainly as a result
     of the increase in EBITDA for the period (a basis for the calculation of
     the fee).

o    An 18.04% increase in concession fees mainly due to higher sales by
     concessionaires.

o    A 1.78% increase in depreciation and amortization, mainly due to the
     depreciation of investments in fixed assets and improvements made to assets
     under the concession.

Operating margin for 4Q03 improved year-over-year to 26.07%, from 18.07%. This
was mainly driven by the 18.04% increase in revenues, primarily the 32.74%
growth in non-aeronautical revenues, which more than offset the 6.50% increase
in costs and expenses.

Mexican companies are generally required to pay the greater of their income tax
liability or their asset tax liability (determined at a rate of 1.8% of the
average tax value of virtually all of the company's assets (including, in ASUR's
case, the concessions), less the average tax value of certain liabilities
(essentially liabilities of companies resident in Mexico, excluding those
related to financial institutions and their intermediaries)). ASUR made asset
tax payments of Ps.41.1 million for 4Q03. Of these payments, Ps.10.8 million
were recorded as an expense in the results for the quarter. The difference was
recorded as an asset, since the Company expects to recover Ps.30.3 million in
future income tax payments.

Net income for 4Q03 was Ps.34.76 million, a decrease of 37.75% compared to 4Q02.
As explained in ASUR's previous press releases, net income for 4Q02 experienced
a one-time positive effect from a change in deferred taxes arising out of a
decrease in the Mexican corporate tax rate. This extraordinary effect on net
income in 4Q02, without a similar effect in 4Q03, is the principal reason for
the decrease in net income between the two quarters.

As a result, earnings per share for 4Q03 declined year-over-year by 37.75% to
Ps.0.1159, or earnings per ADS (EPADS) (one ADS represents ten series B common
shares) of US$0.1031, from earnings per common share of Ps.0.1862, or EPADS of
US$0.1657 for the same period last year.

       31, 2003. U.S. dollar figures are calculated at the exchange rate of
       US$1=Ps. 11.2372.

Total revenues for 2003 were Ps.1,466.6, a year-over-year increase of 13.70%
driven by:

o    An increase of 10.97% in revenues from aeronautical services, resulting
     from the rise in international passengers during the period; and,

o    An increase of 25.11% in revenues from non-aeronautical services,
     principally as a result of the 32.93% year-over-year improvement in
     commercial revenues.

In May 2002, certain airlines informed ASUR of their desire to extend their
payment deadline for passenger charges to 115 days, from the previously
agreed-upon term of 60 days. On November 14, 2003 ASUR signed an agreement with
the airlines which effectively resolved the disputes between the parties. This
agreement grants the airlines the option to pay in 115 days or 60 days. If the
airlines pay in 60 days, they will benefit from prompt payment discounts.

Commercial revenues for 2003 increased year-over-year by 32.93%, mainly due to
the improvement in customer service and commercial offering as follows:

o    A 19.24% rise in duty-free revenues, principally due to the increase in
     international passengers.

o    A 47.28% increase in food and beverage revenues due to the increase in
     passenger traffic and the opening of restaurants and bars in the Cancun,
     Cozumel, Veracruz, Oaxaca, Tapachula and Villahermosa airports.

o    A 40.33% increase in retail revenues, reflecting the growth in passenger
     traffic as well as store openings in the Cancun, Cozumel, Huatulco, Merida,
     Minatitlan, Oaxaca and Veracruz airports.

o    A 66.11% increase in banking and currency exchange revenues as a result of
     two American Express offices becoming fully operational at the Cancun
     Airport.

o    A 99.78% increase in advertising revenues, mainly resulting from the
     dedication of additional space for advertising at the Cancun airport and
     rental space for car exhibits, at the Merida and Villahermosa airports.

Operating costs and expenses for 2003 rose year-over-year by 4.80%, due to the
following:

o    Cost of services for 2003 rose by 1.88% due to increases in insurance and
     maintenance.

o    Administrative expenses increased by 13.64%, mainly as a result of the wage
     increase granted to non-unionized employees during the third quarter of
     2003. Higher administrative expenses were also due to the preparation and
     presentation of investment projects for the Cancun airport and the
     development, design and preparation of the 2004-2008 Master Development
     Plan.

o    Technical assistance costs increased by 18.53%, due to the corresponding
     year-over-year increase in EBITDA.

o    The 13.72% increase in concession fees reflects the year-to-date increase
     in overall revenues.

o    Depreciation and amortization for 2003 rose 1.78%, mainly due to the
     above-mentioned capitalization of investments in fixed assets and
     improvements made to concession assets.

o    Operating margin for 2003 improved to 34.22% from 28.63% in 2002, mainly
     due to the increase in revenue and cost controls.

Net income for 2003 increased 20.58% form 2002 to Ps.276.19 million. Earnings
per common share for 2003 were Ps.0.9206, or EPADS of US$0.8193, compared with
earnings per common share of Ps. 0.7635, or EPADS of US$0.6794 for 2002.

Tariff Regulation
--------------------------------------------------------------------------------

The Mexican Ministry of Communications and Transportation regulates the majority
of ASUR's activities through maximum rates, which represent the maximum annual
amount of revenues per work load unit that may be earned at each airport for
services subject to price regulation.

ASUR's regulated revenues for 2003 were Ps. 1,170.29 million, resulting in a
year-to-date average tariff per traffic unit of Ps. 99.31.

The Mexican Ministry of Communications and Transportation reviews compliance
with the maximum rates on an annual basis at the close of each year.

Under the terms of our concessions, each of ASUR's subsidiary concession holders
is required to submit an updated master development plan for approval by the
Ministry of Communications and Transportation every five years. Each master
development plan covers a fifteen-year period and includes investment
commitments (including capital expenditures and improvements) of the concession
holder for the succeeding five-year period and investment projections (including
capital expenditures and improvements) for the remaining ten years. Once
approved by the Ministry of Communications and Transportation, these commitments
become binding obligations under the terms of our concessions.

ASUR's maximum rates are subject to annual efficiency adjustments, which have
the effect of reducing the maximum rates for each year to reflect projected
efficiency improvements. For the five-year period ending December 31, 2008, the
maximum rates applicable to ASUR's airports will be reduced by an annual
efficiency factor of 0.75% in real terms.

Key Corporate Developments
--------------------------------------------------------------------------------

As a result of the settlement reached by Tribasa with its creditors, it was
decided that Tribasa transfer its ownership stake in Inversiones y Tecnicas
Aeroportuarias, S.A. de C.V. (ITA) in favor of Nacional Financiera S.N.C.
(NAFIN). As determined under the terms of the Participation Agreement among ITA,
the Mexican government and ASUR, the required authorizations were obtained and
the mandatory procedure was followed, including obtaining authorization at
ASUR's shareholder's meeting.

On December 30, 2003 Tribasa transferred its stake in ITA to NAFIN. As a result,
NAFIN has temporarily replaced Tribasa as ITA's Mexican partner until it finds a
party, which meets the original bidding terms for the acquisition of share
capital in ASUR, to purchase the stake.
