Business Editors

MEXICO CITY--(BUSINESS WIRE)--June 5, 2001

Grupo Aeroportuario del Sureste, S.A. de C.V. (NYSE: ASR) (BMV: ASUR) (ASUR), the Mexican operator of nine airports in the southeast region of Mexico, today announced details of the impact on the Company's operations

Between 12:00 AM on Friday, June 1, 2001, and midnight on Saturday, June 2, a total of 106 Aeromexico operations to and from ASUR's airports were cancelled. Of these, 53 were inbound flights and 53 outbound flights.

In a statement, the Company indicated that nearly all the outbound passengers scheduled to leave ASUR airports on cancelled Aeromexico flights were able to find seats on other airlines. The Company is unable to estimate the exact impact of the strike on inbound passenger traffic, because figures of Aeromexico's passengers transported by other airlines into ASUR's airports cannot accurately be estimated and some other passengers might have simply postponed traveling.

Aeromexico is one of the main airlines operating at the ASUR airports. In fiscal 2000 and the first quarter of 2001, Aeromexico transported 1.41 million and 316,000 passengers, respectively, representing 12 percent and 10 percent, respectively, of ASUR's total passenger traffic during those periods.

Aeromexico has operations at the airports of Cancun, Cozumel, Merida, Oaxaca, Tapachula, Villahermosa and Veracruz.
