ASUR Announces Total Passenger Traffic for

November 2006 Up 109.5% Year over Year

Mexico City, December 7, 2006 - Grupo Aeroportuario del Sureste, S.A.B. de C.V. (NYSE: ASR; BMV: ASUR) (ASUR), today announced that total passenger traffic for November 2006 increased by 109.5% when compared to November 2005.

All figures in this announcement reflect comparisons between November 1 through November 30 2005 and 2006. Transit and general aviation passengers are excluded.

The large rise in the year-over-year comparison at Cancun and Cozumel airports was mainly due to sharply reduced passenger traffic in November 2005 as a result of damage inflicted by Hurricane Wilma, which hit the Yucatan Peninsula in October 2005. Although there has since been a substantial recovery, passenger traffic at these airports continues to be affected by the impact of Hurricane Wilma.

Ongoing public demonstrations in the city of Oaxaca have adversely affected tourism in the area and caused the cancellation of 68 flights to Oaxaca airport originally scheduled for November. The protests began in May as a teachers’ strike but have grown into more widespread unrest against the Oaxaca state government. The US State Department recently issued an advisory regarding travel to Oaxaca. At this time we are unable to predict whether or how the conflict will be resolved, or how the ongoing demonstrations may affect our operations.
