Gains of Mexico´s ASUR Climbed a Whopping 57 Percent in First Quarter of 2005

Grupo Aeroportuario del Sureste, S.A. de C.V. (ASUR), the first privatized airport group in Mexico and operator of Cancun Airport and eight others in the southeast of Mexico, today announced results for the three-month period ended March 31, 2005.

For the first quarter of 2005, total passenger traffic increased year- over-year by 11.5 percent; domestic passenger traffic increased by 4.4 percent; and international passenger traffic increased by 15 percent.

The 4.4 percent growth in domestic passenger traffic mainly reflects the 4.1 percent increase in traffic at the Cancun airport.

ASUR classifies revenues from the following activities as commercial revenues: duty free, car rental, retail, banking and currency exchange, advertising, services, non-permanent ground transportation, food and beverage and parking lots.

During 2004, the Company initiated an arbitration process with one of the duty free concessionaires that operates in the Cancun airport. The dispute relates to the amount paid in rent by this concessionaire for the units it occupies in Terminal 1 of this airport. Arbitration proceedings are at an advanced stage, and a final decision is expected during the second quarter of 2005
