Operating Highlights:

Terminal Passenger Traffic

During the fourth quarter of 2005, we experienced an increase in terminal passenger traffic of 11.5% over 4Q04. The greatest increase was at our Los Cabos airport, which experienced a 38.4% rise. Our Puerto Vallarta airport saw an increase of 29.8%, which was due in part to the impact of Hurricane Wilma in the southeast region of Mexico in October 2005, which diverted tourist traffic. We experienced growth throughout the year; notably passenger traffic growth during the first nine months of 2005 was 33.9% and 18.3% at our Los Cabos and Puerto Vallarta airports, respectively.

For the full year 2005, terminal passenger traffic increased 9.2% as compared to 2004. The greatest increase in passenger volumes was at our Los Cabos airport (an increase of 639.6 thousand), followed by our Puerto Vallarta airport (479.5 thousand) and our Guadalajara airport (263.9 thousand). These increases were part of overall international passenger growth of 24.7%, which reflected the rising popularity of Puerto Vallarta and Los Cabos, our main tourist destinations, seasonality and, in part, the effects of Hurricane Wilma.

The following tables provide terminal passenger traffic for the periods indicated (terminal passenger traffic information excludes transit and general aviation passengers).

4Q05 Consolidated Results

Revenues for 4Q05 were Ps. 651.6 million, 11.7% higher than the Ps. 583.5 million obtained in 4Q04, reflecting increases in both aeronautical and non-aeronautical services revenues. A major contributor to this increase was the 11.5% rise in the volume of terminal passengers from 4.3 million to 4.8 million.

- Aeronautical services revenues increased 13.0%.

- Non-aeronautical services revenues increased 6.3%.

Total operating costs and expenses increased 10.5%, primarily as a result of the following:

- Cost of services increased 19.8% due to higher maintenance activity in terminals, access roads and platforms necessary to comply with our Master Development Plan. This increase was higher than that exhibited during the first nine months of 2005 and is in line with previous years, reflecting typical seasonal increases in maintenance activities during the fourth quarter.

- As a result of our improved profitability, the technical assistance fee increased 8.7%.

- As a result of the higher revenues for the period, the government concession fees increased 11.4%.

Operating margin was slightly higher than in 4Q04, rising from 38.5% to 39.2% as a result of the above factors.

Net income increased 233.9% in 4Q05, to Ps. 129.3 million from Ps. 38.7 million for 4Q04. This was due to a Ps. 30.5 million increase in operating income and a reduction in the income tax provision of Ps. 56.7 million, principally due to changes in tax amortization rates applicable to our airport concessions, which was partially offset by the increase in pretax income in 4Q05.

Summary of Consolidated Results for 4Q05 (in thousands):

- U.S. dollar figures were converted from pesos to U.S. dollars at a rate of Ps. 10.6275 per U.S. dollar (the U.S. Federal Reserve noon buying rate at December 30, 2005).

- Under Mexican GAAP EBITDA consists of operating income plus depreciation and amortization. EBITDA calculated according to U.S. GAAP differs from that under Mexican GAAP and would amount to Ps. 373.1 million and Ps. 409.3 million for 4Q04 and 4Q05, respectively.

Consolidated Results for Fiscal Year 2005

Total Revenues for the twelve-month period ended December 31, 2005 were Ps. 2,591.3 million, 14.5% higher than the Ps. 2,263.3 million reported for 2004, as a result of increases in both aeronautical (13.3% over 2004) and non-aeronautical revenues (20.2% over 2004).

Aeronautical revenues increased 13.3% from Ps. 1,865.4 million in 2004 to Ps. 2,112.9 million in 2005, principally reflecting the 4.4% increase in our Maximum Rates, the specific prices charged for various aeronautical services, as well as an 8.5% increase in workload units. Aeronautical revenue per workload unit in 2005 increased by 4.4% as compared to 2004, from 98.4 pesos to 102.7 pesos.

Non-aeronautical revenues increased 20.2%, from Ps. 397.9 million in 2004 to Ps. 478.4 million in 2005, due largely to our recovery in June 2004 of the long-term leases to operate commercial spaces at our Guadalajara and Puerto Vallarta airports (which contributed to revenues for 12 months of 2005 compared to only seven months of 2004). This increase was also attributable to a rise in the leasing of commercial space used for the marketing and sale of time-share units. Revenues from these activities were 102.1% higher in 2005 than in 2004, due largely to a one-time fee received at the Los Cabos airport.

Summary of Consolidated Results for the Fiscal Year (in thousands of pesos unless otherwise noted):

- U.S. dollar figures were converted from pesos to U.S. dollars at a rate of Ps. 10.6275 per U.S. dollar (the U.S. Federal Reserve noon buying rate at December 30, 2005).

- Under Mexican GAAP EBITDA consists of operating income plus depreciation and amortization. EBITDA calculated according to U.S. GAAP differs from that under Mexican GAAP and would amount to Ps. 1,465.3 million and Ps. 1,718.7 million for FY04 and FY05, respectively.

Other Important Data for the Fiscal Year (in thousands):

WLU= Workload unit represents passenger traffic plus cargo units (a cargo unit = 100 kilograms of cargo).

Operating Costs / Expenses for the Fiscal Year (in thousands of pesos):

Total Operating Costs and Expenses

Cost of services as a percentage of revenues decreased from 27.8% in 2004 to 25.1% in 2005, while cost of services per workload unit decreased 4.8% in 2005, from Ps. 33.2 in 2004 to Ps. 31.6 in 2005.

Cost of services increased 3.3% during 2005 versus 2004, due primarily to a 21.0% increase in facility maintenance expenses and a 32.2% increase in professional services costs, which were partly offset by a 72.2% decrease in other expenses. The increase in cost of service is in line with previous years (and also reflects the increased investment in facilities’ infrastructure contemplated in the terms of our concessions).

As a result of the revenue increase being proportionately higher than the cost increase, our technical assistance fee increased 18.3% to Ps. 92.4 million in 2005, as compared to Ps. 78.1 million in 2004.

GAP 4Q05 Page 7 of 17

Reflecting the increase in revenues in 2005, government concession fees increased 14.5%, from Ps. 112.4 million in 2004 to Ps. 128.7 million in 2005.

The 7.7% increase in depreciation and amortization, from Ps. 573.1 million for 2004 to Ps. 617.1 million for 2005, was due in large part to a change made in October 2004 to the amortization rates applicable to the value of the concessions for certain airports for accounting purposes. The change in the amortization rates generated an increase of Ps. 32.0 million in amortization expenses during 2005 compared to 2004. The remainder of the increase was attributable to increases in fixed assets during 2005, consistent with the obligations of our Master Development Plan.

Operating margin increased from 38.4% in 2004 to 42.5% in 2005, reflecting the proportionately greater increase in revenues relative to total operating costs. Operating income increased 26.8% to Ps. 1,102.4 million in 2005, as compared to Ps. 869.5 million in 2004. This increase primarily reflected the 14.5% increase in our total revenues in 2005, which was partially offset by the proportionately smaller increase in total operating costs of 6.8%.

On an airport-by-airport basis, the principal contributors to the increase in operating income during 2005 were our Los Cabos, Puerto Vallarta and Guadalajara airports.

Income Taxes, Employees Statutory Profit Sharing and Asset Tax - The provision for income taxes and employee statutory profit sharing and asset tax declined 4.8% in 2005, to Ps. 454.3 million from Ps. 477.2 million in 2004. This decrease was attributable mainly to the change of tax amortization rates for the concessions during 2005, which was offset in part by the increase in pretax income. Our effective tax rate declined 27.1%, from 56.0% in 2004 to 40.8% in 2005.

Net Income increased 64.6% in 2005, to Ps. 658.8 million from Ps. 400.2 million for 2004. In 2004, net income included a credit of Ps. 25.2 million reflecting the cumulative effect on prior years of the application of Bulletin C-10 (regarding embedded derivatives), while in 2005 this one-time credit did not exist.

Tariff Regulation

The Mexican Ministry of Communications and Transportation regulates the majority of our activities through maximum rates, which represent the maximum aeronautical revenues allowed per workload unit at each airport.

Our regulated revenues for 2005 were Ps. 2,112.9 million, resulting in an average rate per workload unit of 102.7 pesos. Our regulated revenues accounted for 81.5% of total revenues in 2005.

The Mexican Ministry of Communications and Transportation annually reviews our compliance with the maximum rates, and we expect the next such review to take place during the first half of 2006.

Balance Sheet

Despite a dividend payment of Ps. 1,052.2 million and CAPEX of Ps. 581.9 million during 2005, we maintained a healthy cash and short-term investment position, with a year-end balance of cash and cash equivalents of approximately Ps. 899.3 million, 26.8% lower than in December 2004.

Our principal assets consist of the concessions and rights to use airport facilities, with year-end balances of Ps. 17,119.9 million and Ps. 2,393.0 million, respectively, or 70.3% and 9.8% of total assets, respectively.

CAPEX

During 2005 we invested Ps. 581.9 million in fixed assets. This investment was 94.5% greater than in 2004, as required under our Master Development Plan.

In June 2004, we paid Ps. 431.2 million for the early termination of operating lease agreements at our Puerto Vallarta and Guadalajara airports, which has allowed us to operate the most lucrative commercial areas in these airports since that date.

Overview January – February 2006

The following tables show terminal passenger traffic volumes during the first two months of 2006, as compared with the same period of 2005. (Terminal passenger information excludes transit and general aviation passengers.)

Domestic Terminal Passengers (in thousands):

International Terminal Passengers (in thousands):

GAP 4Q05 Page 15 of 17

Total Terminal passengers (in thousands):

Passenger traffic for the first two months of 2006 has grown at a similar rate to 2005, with an 8.6% increase in the number of total terminal passengers year-over-year in the first two months of 2006. The main contributor to this increase was international traffic, which grew 14.3% as compared to the same period of 2005.

Our Los Cabos and Puerto Vallarta airports, experienced the highest growth in passenger traffic, as was the case in 2005. This reflects the growth trend that has been prevalent since 2005, mainly from international passenger traffic led by U.S. and Canadian tourists.

Overview 2006

Passenger traffic was 8.4% higher in January 2005 than in January 2004, while such traffic was only 6.4% higher in February 2005 than in February 2004. Thus, growth slowed in February 2005 by 200 basis points, as compared with the previous month. The full year 2005, however, showed 9.2% growth.

Passenger traffic in January 2006 was 9.2% higher than in January 2005. February 2006 passenger traffic was 7.9% above that in February 2005. Thus, there was some slowing of growth in February 2006, just as in February 2005, but the decline in the growth rate was smaller.

It is difficult to predict the effects that low-cost carriers will have on our results of operations. If these airlines perform well during 2006, the rate of growth of domestic traffic in 2006 could surpass that experienced in 2005.
