          ASUR Announces Total Passenger Traffic up 9.1% Year over Year

Mexico City, August 5th, 2003, Grupo Aeroportuario del Sureste, S.A. de C.V.
(NYSE: ASR; BMV: ASUR) (ASUR) today announced that total passenger traffic for
the month of July 2003 increased by 9.1 percent from the comparable period last
year.

Due to the current situation following the events of September 11, 2001, in the
U.S. and the start of the armed conflict in the Middle East, ASUR's management
is doing an extraordinary effort to publish passenger traffic figures for the
company's airports on a monthly basis to keep investors well informed. Once the
situation has normalized, ASUR management expects to return to normal quarterly
reporting procedures.

All figures in this announcement reflect comparisons between the 28-day period
from July 2 through July 29, 2003, and the equivalent 28-day period last year
from July 3 through July 30, 2002. Transit and general aviation passengers are
excluded.
