Mexico City, July 23, 2003 - Grupo Aeroportuario del Sureste, S.A. de C.V.
(NYSE: ASR; BMV: ASUR) (ASUR), the first privatized airport group in Mexico and
operator of Cancun Airport and eight others in the southeast of Mexico, today

Passenger Traffic
--------------------------------------------------------------------------------

For the second quarter of 2003, year-over-year total passenger traffic increased
by 10.19%; domestic passenger traffic increased by 16.37%; and international
passenger traffic increased by 6.09%.

The 16.37% increase in domestic passenger traffic reflects among other elements,
the fact that Holy Week - one of the main vacation periods in Mexico -- was in
April this year, whereas last year Holy Week was in March, and therefore
reflected in the first quarter figures for 2002.

The 6.09% growth in international passenger traffic was mainly due to an
increase in passenger traffic at the Cancun airport. This was the result of
increased flights on the Cancun-Panama route by the airline Mexicana de
Aviacion; the June opening by America West of the Phoenix-Cancun route, which is
operating at 85% capacity; as well as larger planes flown by Delta Airlines in
response to increased demand. In addition, in January 2003 a new route to
Houston was opened at the Villahermosa airport, which has increased demand.

Total, domestic and international passenger traffic for the first half of the
year increased year-over-year by 9.19%, 10.93% and 8.13%, respectively.

Consolidated Results for 2Q03
--------------------------------------------------------------------------------

Total revenues for 2Q03 reached Ps.357.9 million, representing a year-over-year
increase of 13.31%. This was mainly due to:

     o    An increase of 11.50% in revenues from aeronautical services,
          principally as a result of the above-mentioned increase in passenger
          traffic; and,

     o    An increase of 21.00% in revenues from non-aeronautical services,
          principally as a result of the 29.51% year-over-year improvement in
          commercial revenues.

ASUR classifies revenues from the following activities as commercial revenues:
duty free, car rental, retail, banking and currency exchange, advertising,
teleservices, non-permanent ground transportation, food and beverage and parking
lots.

Commercial revenues improved year-over-year by 29.51%, mainly due to:

     o    A 12.76% increase in duty-free revenues, primarily as a result of the
          increase in international passenger traffic as well as an increase in
          the variety of products offered by the duty-free operators.

     o    An increase of 30.85% in food and beverage revenues, primarily as a
          result of the opening of restaurants and bars in the Veracruz, Oaxaca,
          Huatulco, and Merida airports as well as the increase in passenger
          traffic during the quarter.

     o    A 65.92% increase in retail revenues, as a result of the opening of
          new convenience stores at the Veracruz, Huatulco, Tapachula and
          Villahermosa airports, as well as the increase in passenger traffic
          during the quarter.

     o    A 70.16% increase in advertising revenues, resulting from the
          dedication of additional space for advertising and the distribution of
          print advertising at the Cancun airport.

     o    A 92.93% increase in revenue from banking and currency exchange,
          resulting from American Express being fully operational after the
          completion of the remodeling of Terminal 2, and increased demand for
          currency exchange resulting from higher passenger traffic during the
          quarter.

Total operating costs and expenses for the second quarter increased
year-over-year by 5.17%, mainly as a result of:

     o    A 5.55% rise in costs of services, mainly due to a 40.53% increase in
          the cost of energy resulting from the rate increase.

     o    A 0.72% increase in administrative expenses.

     o    A 16.91% 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    A 13.33% increase in concession fees due to the year-over-year
          improvement in revenues during the quarter.

     o    A 3.47% increase in depreciation and amortization, mainly due to the
          capitalization of investments in fixed assets and improvements made to
          assets under the concession.

Operating margin for the quarter improved year-over-year to 33.96%, from 28.84%.
This was mainly due by the above-mentioned increase in revenues, primarily from
aeronautical revenues, as well as cost controls.

Mexican companies are required to pay the greater of either income tax liability
or asset tax liability (determined at a rate of 1.8% of the average fiscal value
of virtually all of the company's assets (including, in ASUR's case, the
concessions), less the average fiscal 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 the second quarter. Of these payments, Ps. 24.3 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. 16.8 million in
income tax payments.

During the quarter, the Company recorded an extraordinary expense of Ps.12.64
million incurred in connection with the termination of certain lease agreements
in anticipation of the remodeling of the satellite building at Cancun airport.

Net income for the quarter increased year-over-year by 19.82% to Ps.72.52
million. This was principally due to:

     o    The above-mentioned increase in revenues for the period.

     o    The decline in the deferred tax provision derived from the recognition
          of the decline in the corporate tax rate to 32% from 35%, in line with
          Generally Accepted Accounting Principles in Mexico and local tax law.

     o    The decline in the asset tax provision, which in line with the results
          for the airports of Cozumel, Merida, Oaxaca, Veracruz and
          Villahermosa, was adjusted to reflect the amount that exceeded the
          provision for deferred taxes recorded for the corresponding period.

     This adjustment was made in accordance with Bulletin D-4 of the Generally
     Accepted Accounting Principles in Mexico.

Earnings per common share for the quarter were Ps.0.2417, or earnings per ADS
(EPADS) (one ADS represents ten series B common shares) of US$0.2316, compared
with earnings per common share of Ps.0.2017, or EPADS of US$0.1933 for the same
period last year.

Consolidated Results for Six-Month Period
--------------------------------------------------------------------------------

Total revenues for the six-month period were Ps.722.7 million, reflecting a
year-over-year increase of 12.53%. This was mainly due to:

     o    An increase of 9.99% in revenues from aeronautical services, resulting
          from the increase in domestic and international passengers during the
          period; and,

     o    An increase of 23.65% in revenues from non-aeronautical services,
          principally as a result of the 34.30% year-over-year improvement in
          commercial revenues.

The Mexican airlines Aeromexico, Mexicana de Aviacion, Aerolitoral, Aeromar and
Aerovias Caribe oppose the adjustment in ASUR's rates implemented in June 2001
following approval by Mexico's Ministry of Communications and Transportation.
The five airlines suspended this payment in June of 2001 and initiated a lawsuit
against the Ministry of Communications and Transportation to challenge the rate
adjustment. To date, the incremental sum that the five airlines have not paid is
Ps.12.1 million. Legal proceedings regarding this matter are currently on-going.

Similarly, the same airlines informed ASUR in May of 2002 of their desire to
extend the payment deadline for passenger charges to 115 days, from the current
term of 60 days. As a result, starting in June 1, 2002 the five airlines did not
make payments that should have been made according to the original 60-day
payment schedule. As of June 30, 2003 Ps.65.8 million was overdue from these
airlines, as calculated on the original 60-day term.

Commercial revenues for the six-month period increased year-over-year by 34.30%,
mainly due to:

     o    An 11.52% rise in duty-free revenues, principally due to the increase
          in international passengers at the Cancun and Cozumel airports.

     o    A 44.13% increase in food and beverage revenues due to the opening of
          restaurants and bars in Cancun, Merida and Cozumel airports during the
          first half of the year.

     o    A 57.45% increase in retail revenues, reflecting the opening of new
          convenience stores at the Huatulco, Tapachula, Villahermosa and
          Veracruz airports, the increase in average spending per passenger at
          the stores at the check-in areas, particularly at the Cancun airport,
          and the increase in international passenger traffic during the period.

     o    o A 104.34% increase in banking and currency revenues.

     o    o A 139.64% increase in advertising revenues.

</TABLE>

Operating costs and expenses for the six-month period increased year-over-year
by 4.59%.

The cost of services for the six months rose by 2.80% from the same period of
last year, due to increases in the costs of energy and maintenance.

Administrative expenses increased by 4.24%, mainly as a result of a wage
increase granted to non-unionized staff employees during the second quarter of
2002.

Technical assistance costs for the period increased by 16.66%, due to the
corresponding increase in EBITDA during the period.

The 12.55% increase in concession fees was due to the year-to-date increase in
overall revenues.

Depreciation and amortization for the period rose by 3.47%, mainly due to the
above-mentioned capitalization of investments in fixed assets and improvements
made to concession assets.

Operating margin for the six-month period increased to 37.02% from 32.24% for
the equivalent period last year, primarily due to the increase in revenue and
cost controls.

Net income for the six-month period increased year-over-year by 38.87% to
Ps.160.12 million. Earnings per common share for the period were Ps.0.5338, or
EPADS of US$0.5114, compared with earnings per common share of Ps.0.3843, or
EPADS of US$0.3683 for the same period last year.

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

The Mexican Ministry of Communications and Transport regulates the majority of
ASUR's activities through maximum rates, which represent the rates for the
maximum possible revenues allowed per traffic unit at each airport.

ASUR's regulated revenues for the six-month period were Ps.615.00 million,
resulting in a year-to-date average tariff per traffic unit of Ps.95.78.

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