Passenger Traffic

For the fourth quarter of 2004, total passenger traffic increased year-over-year by 11.95%; domestic passenger traffic increased by 4.20%; and international passenger traffic increased by 18.13%.

The 4.20% growth in domestic passenger traffic mainly reflects the 3.6%, 17.22% and 40.84% increase in traffic at the Cancun, Veracruz and Cozumel airports, respectively.

The 18.13% increase in international passenger traffic resulted mainly from a 41.14% and 16.85% growth in traffic at the Cozumel and Cancun airports, respectively.

Total, domestic and international passenger traffic for the fiscal year ended December 31, 2004 increased by 14.00%, 5.60% and 19.97%, respectively.

Consolidated Results for 4Q04

Total revenues for 4Q04 increased year-over-year by 27.69% to Ps. 465.69 million. This was mainly due to:

•	An increase of 23.23% in revenues from aeronautical services, principally as a result of the above-mentioned increase in passenger traffic, and

•	An increase of 42.55% in revenues from non-aeronautical services, principally as result of the 62.76% increase in commercial revenues.

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

ASUR 4Q04, Page 3 of 18

Commercial revenues improved year-over-year by 62.76%, mainly due to:

•	A 40.22% increase in duty-free revenues, primarily as a result of the growth in international passenger traffic and improved product mix.

•

An increase of 83.12% in food and beverage revenues, primarily resulting from revenues from ASUR’s direct operation of a restaurant and a snack bar which were taken over from a former concession holder in May 2004. The increase in food and beverage revenues also reflects new store openings as listed below:

•	A 259.85% increase in retail revenues, mainly as a result of growth in international passenger traffic during the quarter, revenues from the direct operation of three convenience stores previously operated by a former concessionaire and the new store openings listed below:

ASUR 4Q04, Page 4 of 18

During 2004, the Company initiated an arbitration process with one of the duty free concessionaires (Dufry Mexico S.A. de C.V.) 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 first quarter of 2005.

Total operating costs and expenses for 4Q04 increased year-over-year by 8.01% primarily as a result of:

•

A 21.13% increase in costs of services mainly as a result of the costs related to ASUR’s direct commercial operation of a restaurant, a snack bar and three convenience stores previously operated by a former concessionaire, an increase in maintenance expenses as well as higher payroll resulting from the reallocation of certain functions from ASUR’s corporate headquarters to the airport level, principally at Cancun.

•	A 46.28% increase in the cost of technical assistance, principally due to the increase in EBITDA for the quarter (a basis for the calculation of the fee).

•	A 27.69% increase in concession fees mainly due to higher revenues.

•

An 8.46% increase in depreciation and amortization, resulting from the capitalization of investments in fixed assets, improvements made to concession assets and ASUR’s direct commercial operation of a restaurant, a snack bar and three convenience stores previously operated by a former concessionaire.

•	The increase in costs was partially offset by a 40.86% decline in Administrative expenses reflecting the reorganization in February 2004 of certain functions from the corporate to the airport level.

Operating margin for 4Q04 improved to 37.47% from 26.07% in the fourth quarter of last year. This was mainly driven by the 27.69%, increase in revenues, primarily the result of the 23.23% growth in aeronautical revenues, which more than offset the 8.01% increase in costs and expenses for the quarter.

ASUR 4Q04, Page 5 of 18

Mexican companies are generally required to pay the greater of their income tax liability or their asset tax liability (determined at a rate of 1.8% of the average tax value of virtually all of the company’s assets (including, in ASUR’s case, its concessions), less the average tax value of certain liabilities (essentially liabilities of companies resident in Mexico, excluding those related to financial institutions and their intermediaries)). ASUR made asset tax payments of Ps.39.0 million for 4Q04. Of these payments, Ps.15.0 million was recorded as an expense in the results for the quarter. The difference was recorded as an asset, since the Company expects to recover Ps.24.0 million as a credit against future income tax payments.

Due to recent changes in the Mexican Income Tax Law, effective January 1, 2005 the income tax rate will be reduced gradually by 1% per year beginning in 2005 until 2007, when it will be 28%. As a result of this change, and after consultation with its external auditor, ASUR reversed a portion of its provision for deferred taxes to reflect the change in tax rates and Ps.113.82 million were recorded as an income for the quarter in accordance with Mexican GAAP.

Net income for 4Q04 was Ps.194.59 million, a year-over-year increase of 432.10%. Earnings per common share for the quarter were Ps.0.6487, or earnings per ADS (EPADS) (one ADS represents ten series B common shares) of US$0.5818. This compares with Ps.0.1219, or EPADS of US$0.1093, for the same period last year.

Consolidated Results for Fiscal Year 2004

Total revenues for Fiscal Year 2004 increased year-over-year by 28.08% to Ps.1,975.97 million. This was mainly due to:

•	An increase of 21.87% in revenues from aeronautical services, principally as a result of the above-mentioned increase in international passenger traffic, and

ASUR 4Q04, Page 7 of 18

•	An increase of 51.13% in revenues from non-aeronautical services, principally as result of the 69.35% increase in commercial revenues.

Commercial revenues for 2004 increased year-over-year by 69.35%, mainly due to:

•	A 51.21% rise in duty-free revenues, principally due to the increase in international passenger traffic.

•	A 76.20% increase in food and beverage revenues, reflecting revenues from the restaurant and the snack bar which have been operated by ASUR since May 2004, as well as the concession revenues generated by new stores at the Cancun, Cozumel, Oaxaca, Tapachula, Veracruz and Villahermosa airports.

•

A 193.15% increase in retail revenues, principally resulting from revenue from the three convenience stores that have been operated by ASUR since May 2004. The increase in retail revenues also reflects income from the concessions granted for new convenience stores at the Cancun, Huatulco and Oaxaca airports and other store openings at Cancun airport.

•	A 17.81% increase in revenue from banking and currency exchange services.

•

A 75.74% increase in revenue resulting from new contacts which ASUR has entered into with car rental companies, that provide for payments to ASUR of the greater of either a minimum guaranteed fixed fee or a fixed percentage of each rental car company’s revenues. Prior contracts provided only for a fixed fee.

•	A 56.46% increase in advertising revenues.

		Note:	Figures are shown in thousands of constant Mexican pesos as of December 31, 2004.

Costs and expenses for 2004 increased year-over-year by 12.17%.

•

Costs of services for the period increased year-over-year by 21.59%. This increase was primarily due to the reallocation in February 2004 of certain functions from the corporate to the airport level, particularly at Cancun airport, as well as costs related to the direct operation by ASUR of a restaurant, a snack bar and three convenience stores beginning in May 2004.

•	Technical assistance costs increased by 38.00%, reflecting the corresponding increase in EBITDA during the period.

•	Concession fees increased 28.08% mainly due to higher revenues.

•	Depreciation and amortization rose by 7.11%, mainly due to the capitalization of investments in fixed assets and improvements made to concession assets.

•	The increase in costs was partially offset by a 19.80% decline in Administrative expenses reflecting the reorganization in February 2004 of certain functions from the corporate to the airport level.

Operating margin rose to 42.39%, up from 34.22% for fiscal year 2003. This increase was mainly due to the 28.08% increase in revenues and cost controls.

Net income for fiscal year 2004 increased by 108.93% to Ps.606.99 million. Earnings per common share for the period were Ps.2.0233, or earnings per ADS (EPADS) (one ADS represents ten series B common shares) of US$1.8147. This compares with Ps. 0.9684, or EPADS of US$0.8686, for the same period last year.

ASUR 4Q04, Page 10 of 18

Tariff Regulation

The Mexican Ministry of Communications and Transportation regulates the majority of ASUR’s activities through maximum rates, which represent the rates for the maximum possible revenues allowed per traffic unit at each airport.

ASUR’s regulated revenues for fiscal year 2004 were Ps.1,439.11 million, resulting in an annual average tariff per work load unit of Ps.100.27. ASUR’s regulated revenues accounted for approximately 72.83% of total income for the period.

The Mexican Ministry of Communications and Transportation reviews compliance with the maximum rates on an annual basis at the close of each year.

Balance Sheet

On December 31, 2004, Airport Facility Usage Rights and Airport Concessions represented 87.64% of the Company’s total assets, with current assets representing 10.64% and other assets representing 1.72%.

On December 31, 2004 cash and marketable securities were Ps.1,146.05 million. On the same date, shareholder’s equity was Ps.12,326.31 million and total liabilities were Ps. 728.22 million, representing 94.42% and 5.58% of total assets, respectively. Total deferred liabilities represented 73.67% of the Company’s total liabilities.

Capex

During the quarter, ASUR made investments of Ps.204.42 million as part of the Company’s ongoing plan to modernize its airports. Capital investment for fiscal year 2004 totaled Ps.421.52 million.

ASUR 4Q04, Page 11 of 18

Corporate Headquarters

During December 2004, ASUR moved its corporate headquarters to:

Bosque de Alisos 47-A
Bosque de las Lomas
C.P. 05120 México D.F.

ASUR’s phone number remains unchanged:

Te: (52) 55-52-84-04-00

Potential Competition at the Cancun Airport

In accordance with Airport Law, the Ministry may grant concessions for the administration, operation, use, and in some cases, construction of airports, without public bidding when the following entities are involved:

•	Entities of the Federal Public Administration.

•	Companies whose majority interest is owned by the governments of the federal or municipal entities formed for the administration, operation, use, and in some cases, construction of airports.

ASUR has learned that in October 2004, the Mexican state of Quintana Roo formed a majority state-owned company named Aeropuerto Internacional de la Riviera Maya, SA de C.V. to seek a concession from the Mexican federal government to build and operate a new international airport in the Mayan Riviera region of the state.

ASUR has no further details on the construction or projected opening of the airport and is unable to predict the effect that it may have on ASUR’s passenger traffic or operating results if the project is successfully carried out.

In addition, there can be no assurance that the Ministry will not grant concessions for the administration, operation, use, and construction of airports that could compete with ASUR’s airports, nor that a state government will not seek to do so, in which case ASUR’s business, operating results, forecasts and financial situation could be adversely affected.

ASUR 4Q04, Page 12 of 18

Subsequent Events

1.	On January 17, 2005 ASUR held a General Ordinary Shareholders' Meeting. The resolutions approved by the shareholders at the meeting were as follows:

Nacional Financiera, S.N.C. (“Nafin”) was authorized to transfer its 25.5% equity interest in Inversiones y Técnicas Aeroportuarias, S.A. de C.V. (“ITA”), Asur’s strategic partner, to Mr. Fernando Chico Pardo. As a result, Mr. Chico Pardo was authorized to replace Nafin as the Mexican Partner in ITA, pursuant to the Participation Agreement among ITA, the Mexican government and ASUR.

II.	Special delegates of the General Ordinary Shareholders’ Meeting were appointed to appear before a Mexican notary public to legalize the minutes of the Meeting.

Following the transfer of Nafin’s shares to Mr. Chico Pardo, ITA’s shareholders will be:

NAFIN acquired the abovementioned 25.5% stake in ITA on December 30, 2003 as part of a settlement by Triturados Basálticos y Derivados, S.A. de C.V.’s (Tribasa) with its creditors. As a result, NAFIN became ITA’s temporary Mexican partner until its ownership stake was sold to another shareholder who met the requirements to be part of ITA as its Mexican partner.

ITA became ASUR's strategic partner in 1998 when it acquired a 15% interest in ASUR as part of the privatization of the airport system in Mexico. According to the original agreements signed by ASUR and the Mexican Federal Government, Copenhagen Airports, acting as ITA’s operating partner, and Tribasa, acting as the Mexican partner, were

required to maintain their ownership stake in ITA for 15 years (except for transfers permitted under certain conditions provided in such agreements).
