ASUR Announces Total Passenger Traffic for
September 2005 Up 0.3% Year over Year

Mexico City, October 6, 2005, Grupo Aeroportuario del Sureste, S.A. de C.V. (NYSE: ASR; BMV: ASUR) (ASUR) today announced that total passenger traffic for the month of September 2005 increased by 0.3% percent when compared to September 2004, reflecting the impact of Hurricane Emily.

All figures in this announcement reflect comparisons between the 30-day period starting September 1 through September 30, 2005 and 2004. Transit and general aviation passengers are excluded.

Hurricane Emily, which hit the region in July 2005, forced the closure of 5,153 and 500 hotel rooms in Cancun and Cozumel respectively. These numbers represent 9.98% and 13.40% of the hotel rooms which were available in these cities prior to the hurricane. As of the last day of the month of September, 2,918 rooms were out of service from the original 5,153. Asur’s management believes that the lower passenger traffic numbers to these resorts during September were largely the result of the reduction in available accommodation.

The region’s Municipal Tourism Authority currently estimates that 1,561 rooms are expected to open in October; 797 are expected to open in November; and 497 are expected to open in December. There is as yet no opening date for the remaining 63 rooms in Cancun.

In Cozumel, the owners of two hotels which closed a total of 500 rooms estimate that these rooms will be reopened in November 2005.
