Mexico D.F., October 22, 2003 Grupo Aeroportuario del Sureste, S.A. de C.V.
(NYSE:ASR; BMV:ASUR), (ASUR), the first privatized airport group in Mexico and

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

For the third quarter of 2003, year-over-year total passenger traffic increased
by 10.45%; domestic passenger traffic increased by 7.56%; and international
passenger traffic increased by 12.98%.

The 7.56% increase in domestic passenger traffic reflects a 9.65% growth in
passenger traffic at Cancun airport. This resulted from increased flights by
certain airlines as well as traffic related to the Fifth World Trade
Organization Ministerial Conference held in Cancun in September 2003. Growth in
domestic passenger traffic also reflects a 14.56% increase at the Villahermosa
airport, as a result of additional flights, and a 15.69% increase at the Cozumel
airport, as a result of new flights to Mexico City.

The 12.98% growth in international passenger traffic was mainly due a 13.72%
increase in passenger traffic at Cancun airport. This was the result of
increased flights by certain airlines, as well as the above-mentioned World
Trade Organization Conference. Additionally, passenger traffic at the
Villahermosa airport increased due to a new route to Houston introduced in
January 2003. Passenger traffic at Oaxaca and Huatulco increased due to
additional flights to San Antonio and at Tapachula, as a result of flights to
Ecuador.

Total domestic and international passenger traffic for the nine-month period
ended September 30, 2003 increased year-over-year by 9.61%, 9.64% and 9.58%,
respectively.

Consolidated Results for 3Q03
--------------------------------------------------------------------------------

Total revenues for 3Q03 reached Ps.369.9 million, representing a year-over-year
increase of 12.24%. This was mainly due to:

o    An increase of 10.16% in revenues from aeronautical services, principally
     as a result of the above-mentioned increase in passenger traffic; and,

o    An increase of 20.82% in revenues from non-aeronautical services,
     principally as a result of the 24.24% 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 24.24%, mainly due to:

     o   A 28.48% increase in duty-free revenues, primarily as a result of the
         increase in international passenger traffic.

     o   An increase of 40.61% in food and beverage revenues, primarily the
         result of an improvement in the product availability and pricing, as
         well as the opening of restaurants and bars in the Cancun and Cozumel
         airports. At Cancun airport, Domino's Pizza and Tequileria opened in
         October 2002 and September 2003, respectively. At Cozumel airport,
         Colombian Cafe opened in July 2003. The above mentioned increase also
         resulted from the opening of new food and beverage stores at the
         Veracruz, Oaxaca, Tapachula and Villahermosa airports from April
         through July, 2003.

     o   A 20.86% increase in retail revenues, principally due to increased
         passenger traffic and the opening of new stores. At the Cozumel
         airport, Articulos Selectos de Carlos & Charly's opened in June 2003,
         and Sunglass Island and Hard Rock Cafe opened in July, 2003. At Merida
         airport, Grupo Agroindustrial opened in February of 2003. At Huatulco,
         Irale opened in February 2003, at Oaxaca, Mezcal Beneva opened in June
         2003, and at Veracruz, Amara opened in March 2003.

     o   A 51.69% 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 19.89% increase in revenue from banking and currency exchange,
         resulting from American Express becoming fully operational after the
         completion of the remodeling of Terminal 2. at the Cancun Airport.


On September 25, 2003 ASUR inaugurated the Jose Cuervo Tequileria restaurant
located in the international gate of the satellite building at the International
Airport of Cancun. The restaurant is operated by Controladora Mera, S.A. of
C.V., one of the food and beverages concessionaires of the Cancun, Merida and
Cozumel airports. This addition should make the overall experience of passengers
traveling though the Cancun airports more comfortable and enjoyable.

In addition, ASUR also awarded the 20-year gas station and convenience store
concession to operate in the International Airport of Cancun to Mexico-based
PERC Group. PERC Group has over 23 years of experience in the operation of gas
stations and currently operates 23 service stations located throughout Mexico.

Total operating costs and expenses for the third quarter increased
year-over-year by 4.85%, mainly as a result of:

o    A 3.83% rise in costs of services, mainly due to increases in maintenance
     costs for the quarter resulting from maintenance work not being completed
     in the scheduled time during the first half of the year.

o    A 7.57% increase in administrative expenses as a result of an increase in
     wages granted to non-unionized employees during August 2003.

o    A 16.86% 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 12.24% increase in concession fees due to the year-over-year improvement
     in revenues during the quarter.

o    A 2.21% 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 34.87%, from 30.28%.
This was mainly driven by the 12.24% increase in revenues, primarily by the
20.82% growth in non-aeronautical revenues, more than offsetting the 4.85%
increase in costs and expenses.

Operating profit and EBITDA at the Merida airport declined by 47.47% and 12.89%,
respectively during the quarter, mainly due to increases in maintenance costs.

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 third quarter. Of these payments, Ps. 9.5 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.31.6 million in
future income tax payments.

ASUR has reclassified a portion of taxes paid in previous years, reflecting a
higher certainty of recovering these taxes in the future.

Net income for the quarter increased year-over-year by 39.86% to Ps.73.09
million. This was principally due to:

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

o    The decline in ASUR's provision for deferred taxes resulting from the
     decrease in the corporate tax rate to 32% from 35%, in line with Generally
     Accepted Accounting Principles in Mexico and the amendment to the Mexican
     Income Tax Law effective January 1, 2002.

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 deferred taxes provision

Consolidated Results for the Nine-Month Period
--------------------------------------------------------------------------------

Total revenues for the nine-month period were Ps.1,102.1 million, reflecting a
year-over-year increase of 12.43%. This was mainly due to:

      o  An increase of 10.04% in revenues from aeronautical services, resulting
         from the increase in international passengers during the period; and,

      o  An increase of 22.66% in revenues from non-aeronautical services,
         principally as a result of the 30.70% year-over-year improvement in
         commercial revenues.

While the June 2001 suspension of the rate adjustment payment to ASUR by the
Mexican airlines Aeromexico, Mexicana de Aviacion, Aerolitoral, Aeromar and
Aerovias Caribe has still to be resolved, all parties involved have maintained
conversations aimed at achieving a mutually beneficial agreement. To date, the
incremental sum that the five airlines have not paid is Ps.13.4 million.

The same airlines informed ASUR in May of 2002 of their desire to extend their
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 to ASUR that should have been made according to the original 60-day
payment schedule. As of September 30, 2003 Ps.97.1 million was overdue from
these airlines, as calculated based on the original 60-day term.

Commercial revenues for the nine-month period increased year-over-year by
30.70%, mainly due to the improvement in customer service and commercial
offering as follows:

      o  A 16.42% rise in duty-free revenues, principally due to the increase in
         international passengers.

      o  A 42.93% 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
         during the nine-month period.

      o  A 42.27% increase in retail revenues, reflecting the growth in
         passenger traffic as well as the opening of new convenience stores at
         the Huatulco, Tapachula, Villahermosa and Veracruz airports.

      o  A 64.16% increase in banking and currency exchange revenues.

      o  A 96.01% increase in advertising revenues.

   ----------------------------------------------------------------------------

Note:    Figures are shown in thousands of constant Mexican pesos as of
         September 30, 2003.


Operating costs and expenses for the nine-month period increased year-over-year
by 4.35%.

The cost of services for the nine months rose by 3.16% from the same period last
year, due to increases in the costs of energy and maintenance.

Administrative expenses increased by 5.42%, mainly as a result of a wage
increase granted to non-unionized employees during the third quarter of 2003.

Technical assistance costs increased by 16.73%, due to the corresponding
increase in EBITDA during the period.

The 12.45% increase in concession fees was due to the year-to-date increase in
overall revenues.

Depreciation and amortization for the period rose by 2.21%, mainly due to the
above-mentioned capitalization of investments in fixed assets and improvements
made to concession assets.

Operating margin for the nine-month period increased to 36.51% from 31.60% for
the equivalent period last year, primarily due to the increase in revenue and
cost controls.

Net income for the nine-month period increased year-over-year by 40.09% to
Ps.235.94 million. Earnings per common share for the period were Ps.0.7865, or
EPADS of US$0.7140, compared with earnings per common share of Ps.0.5614, or
EPADS of US$0.5097 for the same period last year.


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

The Mexican Ministry of Communications and Transportation 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 nine-month period were Ps.919.3 million,
resulting in a year-to-date average tariff per traffic unit of Ps.95.08. The

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

We are currently in the process of the maximum tariff review for the period of
2004 - 2008.


Balance Sheet
--------------------------------------------------------------------------------

On September 30, 2003, Airport Facility Usage Rights and Airport Concessions
represented 87.84% of the Company's total assets, with current assets
representing 8.78% and other assets representing 3.47%.

On September 30, 2003, cash and marketable securities were Ps.702.79. On the
same date, shareholders' equity represented 94.90% and total liabilities
represented 5.10% of ASUR's total assets. Total deferred liabilities represented
75.17% of the Company's total liabilities.

Capex
--------------------------------------------------------------------------------

During the quarter ASUR made investments of Ps.68.9 million as part of the
Company's ongoing plan to modernize the airports of the group. Management
estimates that an additional Ps.152 million will be invested during the
remainder of this year.

Labor Relations
--------------------------------------------------------------------------------

During the month of October, ASUR reached a mutually satisfactory agreement on
the revision of wages with the Mexican National Union of Airport Workers.
