|ASUR Announces Total
Passenger Traffic up 11.8% Year over Year


Mexico City, September 8th, 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 August 2003 increased by 11.8
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 30 through August 26, 2003, and
the equivalent 28-day period last year from July 31 through August 27, 2002. Transit and
general aviation passengers are excluded.
