Guadalajara, Jalisco, Mexico, July 23, 2007 - Grupo Aeroportuario del Pacífico, S.A.B. de C.V. (NYSE:PAC; BMV:GAP) (“the Company” or “GAP”) today reported unaudited results for the quarter ended June 30, 2007. Figures are unaudited and have been prepared in accordance with Financial Reporting Standards in Mexico (NIF). Except as otherwise indicated, all peso amounts are presented herein in constant pesos with purchasing power as of June 30, 2007.

•

Revenues increased 16.1% (by Ps. 117.6 million), due to a Ps. 86.6 million (14.6%) increase in revenues from aeronautical services and a Ps. 31.1 million (22.9%) increase in revenues from non-aeronautical services, representing 73.6% and 26.4% of the total increase in revenues, respectively.

•

Revenues from aeronautical services mostly increased due to passenger tariffs, which rose 24.5% from Ps. 474.4 million in 2Q06 to Ps. 590.4 million in 2Q07 (representing a higher Ps. 116 million, or 24.5%), as compared to 2Q06, while non-aeronautical revenues rose due to an increase in revenues from parking and the leasing of space to the following: time-share developers, airlines (not related to their operations) and to bars and restaurants.

•

As a result of the increase in revenues, the cost of government concession fees increased 16.3%. The technical assistance fee increased 20.7%, also as a result of the increase in revenues, which was partially offset by a 5.9% increase in the cost of services (excluding payment for technical assistance, depreciation and amortization).

•

Net income increased Ps. 99.3 million, or 55.2%, mainly due to the aforementioned factors, as well as a decrease in the effective tax rate for the quarter by 12.5 percentage points, from 45.0% to 32.5%.

¹Workload units represent passenger traffic plus cargo units (1 cargo unit = 100 kilograms of cargo).

During the second quarter of 2007, the Company reported an increase in the number of total terminal passengers by 18.6%, driven by a 36.9% increase in the number of domestic passengers.

Domestic Passenger Traffic, during the second quarter of 2007, experienced a net increase of 1.0675 million passengers, a 36.9% increase, as compared to the second quarter of 2006. This was the result of a combined increase of 1.0685 million passengers at all of the Company’s airports except the Manzanillo airport, which was slightly offset by a 1,000-passenger decrease.

Of the 1.0685 million passenger increase, it is important to note that terminal passenger traffic rose by 358.1 thousand at the Tijuana airport, 304.5 thousand at the Guadalajara airport, 74.8 thousand at the La Paz airport, 67.2 thousand at the Bajio airport, 50.9 thousand at the Hermosillo airport, 46.5 thousand at the Los Cabos airport, 43.7 thousand at the Puerto Vallarta airport, 36.8 thousand at the Los Mochis airport, 33.0 thousand at the Mexicali airport, 32.7 thousand at the Aguascalientes airport and 20.3 thousand at the Morelia airport.

In the cases of the Guadalajara, Tijuana, Los Mochis, La Paz, Hermosillo, Mexicali, Aguascalientes, Morelia and Bajio airports, the growth resulted primarily from the increase in the number of seats available due to the initiation of new routes and greater flight frequencies by low-cost carriers. In the case of Los Cabos and Puerto Vallarta, the increase was caused by the initiation of operations by low-cost carriers at these airports as well as the growing popularity of these cities as tourist destinations among domestic travelers.

We are still experiencing the effects of the suspension of Aerocalifornia that took place in April of 2006. However, when we compare results year on year, the figures are higher than expected since this airline was not operating during this period in 2006.

International passenger traffic declined by 164.3 thousand terminal passengers, as compared to the second quarter of 2006. This was the result of a combined decrease in international terminal passengers of Ps. 150.8 million at the Guadalajara, Los Cabos, Puerto Vallarta, Morelia, Bajio, Aguascalientes, Hermosillo, Manzanillo and Mexicali airports. This was partially offset by a combined increase of 13.5 thousand passengers at the La Paz, Tijuana and Los Mochis airports.

In the case of Guadalajara, Bajio, Aguascalientes and Morelia, the decrease in international passenger traffic was possibly partially a result of the substitution effect as several low-cost carriers have increased the number of flights to and from Tijuana. This has resulted in numerous passengers choosing to travel to the United States via Tijuana due to lower fares, therefore decreasing traffic on flights to and from California. It is important to note that the decline in international terminal passenger traffic at the Los Cabos and Puerto Vallarta airports is related to the fact that the effects of Hurricane Wilma, which, in 2006, caused damage to the airports and tourist destinations of the Gulf of Mexico region - i.e. Cancun and Cozumel – and affected the second quarter of 2006 results but were no longer a factor in the 2Q07 results. In the case of Hermosillo, the decrease occurred mostly on the Hermosillo-Phoenix route.

The offsetting increase of 13.5 thousand passengers at other airports was due to the rise in traffic at the La Paz (9.9 thousand), Tijuana (3.4 thousand) and Los Mochis (0.2 thousand) airports, representing increases of 191.0%, 96.4% and 15.5%, respectively, compared to the second quarter of 2006.

In the case of the La Paz airport, the increase in passenger traffic was due to the growth in routes to and from the United States; in the case of Tijuana, traffic growth was driven by the introduction of the Tijuana-Tokyo route by Aeromexico, and in the case of Los Mochis, it was driven by the Los Mochis–Los Angeles route operated by Delta Airlines.

During the second quarter of 2007, the low-cost carriers (Alma, Interjet, Volaris, Click, A Volar and VivaAerobus) transported a total of 1,405.5 thousand domestic passengers (35.5% of GAP’s domestic traffic) to and from the airports of Aguascalientes, Bajio, Guadalajara, Hermosillo, La Paz, Los Mochis, Morelia, Mexicali, Puerto Vallarta, Los Cabos and Tijuana. As of June 30, 2007, these six airlines offered a total of 833 weekly frequencies and 49 routes at GAP’s airports, which represents 11 more routes than in the first quarter of 2007.

Total passenger traffic for the first half of 2007, as compared with the same period of 2006, increased 13.2% by 1.3428 million passengers. This was driven by an increase in domestic passenger traffic of 1.6528 million passengers, or 28.7%, and a decrease in international passenger traffic of 309.9 thousand passengers, a 7.0% decline. The most notable increases in domestic passenger traffic took place at the airports in Tijuana and Guadalajara with 572.1 thousand and 518.2 thousand additional passengers, respectively, representing increases of 34.2% and 28.3%, respectively. This was due largely to the higher number of available seats on low-cost carrier flights to and from those airports.

The decline in international passenger traffic during the first half of 2007 was most notable at the airports in Guadalajara, Los Cabos and Puerto Vallarta, which experienced declines of 115.6 thousand passengers (-9.9%), 89.3 thousand passengers (-7.2%) and 56.3 thousand passengers (-4.0%), respectively. The decrease in Guadalajara was due to customer preference of traveling to the United States via Tijuana and in the case of the other two, it was in part due to the effects of Hurricane Wilma, which made Los Cabos and Puerto Vallarta attractive alternatives to Cancun and Cozumel during 2006.

Revenues for the second quarter of 2007 increased Ps. 117.6 million, or 16.1%, as compared to the second quarter of 2006. This increase, from Ps. 729.5 million to Ps. 847.1 million, was mainly due to:

- Aeronautical services revenues, which increased by Ps. 86.6 million, or 14.6% compared to the second quarter of 2006, due primarily to increased revenues from passenger charges, which rose by Ps. 116.0 million, and represented 134.0% of the increase in aeronautical services revenues and 98.6% of the total revenue increase. This increase was partially offset by a decline in revenues from airplane landing and parking fees by Ps. 31.8 million, a reduction of 46.4% when compared to the second quarter of 2006. This decline was mainly attributable to the suspension of Aerocalifornia’s operations that took place during the second quarter of 2006. As a result of the suspension in 2006, Aerocalifornia parked its airplanes at several of the Company’s airports, and was charged long-term parking fees, which was not the case during the second quarter of 2007. With respect to airplane landing revenues, the decline was a result of the decrease in international operations at certain airports.

- Non-aeronautical services revenues increased by 22.9%, or Ps. 31.1 million, when compared to the second quarter of 2006. The line items that drove this growth were revenues from the leasing of space to time-share developers, revenues from parking and revenues from leasing of commercial spaces, food and beverage spaces, advertising and car rentals. These led the overall increase in commercial revenues by Ps. 27.5 million, representing 88.6% of the increase in non-aeronautical services (representing 23.4% of the total revenue increase). Non-aeronautical services revenues per passenger during 2Q07 were Ps. 28.5, as compared to Ps. 27.5 in 2Q06, an increase of 3.7%.

Total operating costs and expenses increased by Ps. 18.4 million, an increase of 7.1%, primarily due to the following:

• Employee costs decreased by 0.4%. This was due to a 62.5% decline in severance payments.

• Maintenance costs increased by Ps. 3.5 million, an increase of 10.2%, due to several maintenance projects that took place prior to the rainy season, mainly on the taxiways and runways of the airports, as well as maintenance performed on buildings and installations.

• Service costs increased by Ps. 1.5 million, or 7.0%, mainly as a result of higher electricity consumption due to additional infrastructure necessary to comply with the Company’s master development programs.

• Other operating costs increased by Ps. 2.5 million, or 9.4% as compared to the second quarter of 2006. This was mainly the result of the leasing costs paid to Shared Counter Spaces (CUTE), which was hired at the beginning of 2007, to provide counters used by various airlines in our airports. This cost also includes employee profit sharing amounting to Ps. 0.3 million in the second quarter of 2007, which in 2006 was reported as a tax expense.

The Company’s operating margin increased by 4.8 percentage points, from 41.1% in 2Q06 to 45.9% in 2Q07. This increase was mainly the result of the increase in revenues and controlled operating costs, while the EBITDA margin increased 2.7 percentage points, from 64.6% in 2Q06 to 67.3% in 2Q07.

Net income for the quarter rose by Ps. 99.3 million, or 55.2% compared to 2Q06. Due to the aforementioned factors, net income before taxes increased 26.7%. In addition, there was a tax benefit of Ps. 12.0 million in 2Q07 (reducing tax from Ps. 146.6 million in 2Q06 to Ps. 134.6 million in 2Q07, lowering the effective tax rate from 44.9% in 2Q06 to 32.5% in 2Q07). This tax reduction was a result of the favorable ruling the Company received in 4Q06 regarding the asset tax treatment of the airports in Aguascalientes, Hermosillo, La Paz, Los Mochis, Manzanillo and Morelia, as well as changes in the asset tax law for 2007.

- U.S. dollar figures were converted from pesos to U.S. dollars at a rate of Ps. 10.7901 per U.S. dollar (the U.S. Federal Reserve noon buying rate at June 29, 2007).

Workload units represent passenger traffic plus cargo units (1 cargo unit = 100 kilograms of cargo).

Revenues for the first half of 2007 increased by Ps. 203.3 million, or 13.9% as compared to the first half of 2006. This increase from Ps. 1,458.1 million to Ps. 1,661.4 million, was mainly due to the following:

- Aeronautical services revenues, which increased by Ps. 144.4 million, or 12.0%, with respect to the first half of 2006. The increase was mainly a result of increased revenues from passenger tariffs, which increased by Ps. 168.2 million (representing 116.6% of the increase in aeronautical services revenues and 82.8% of the increase in total revenues). However, this increase was affected, in part, by a decrease in revenues from airplane landing and parking fees by Ps. 30.5 million, a reduction of 46.7% with respect to the first half of 2006. The higher landing and parking fees during the second quarter of 2006 resulted from the suspension of Aerocalifornia’s operations, which took place during the first half of 2006. As a result, of that suspension, Aerocalifornia parked its airplanes at several of the Company’s airports, and was charged long-term parking fees, which was not the case during the first half of 2007. With respect to airplane landing revenues, the decline was a result of the decrease in international operations at certain airports.

Non-aeronautical services revenues increased by 22.9%, or Ps. 58.9 million, as compared to the first half of 2006. The line items that drove this growth were revenues from the leasing of space to time-share developers (an increase of Ps. 17.1 million, or 96.1%, from 2006), revenues from parking (an increase of Ps. 11.7 million, or 23.1%), leasing of commericial spaces (an increase of Ps. 8.14 million, or 21.8%), duty-free shops (an increase of Ps. 6 million, or 22.6%), leasing of food and beverage spaces (an increase of Ps. 5.7 million, or 23.1%)and car rentals (an increase of Ps. 5.2 million, or 20.3%). These items represented a total increase of 29.5% (Ps. 53.9 million) with respect to the first half of 2006 and represented 91.5% of the increase in non-aeronautical revenues and 26.5% of the increase in total revenues. Non-aeronautical revenues per passenger reached Ps. 27.5 in the first half of 2007, while in the first half of 2006 they totaled Ps. 25.3 per passenger, representing an increase of 8.5%.

Total operating costs and expenses increased by Ps. 30.3 million during the first half of 2007, an increase of 6.3%, primarily as a result of the following:

• Employee costs decreased by 1.5%, mainly due to a 61.7% reduction in severance payments.

• Maintenance costs increased by Ps. 4.9 million, or 8.8%, due to several maintenance projects that took place in airport installations in order to comply with security and customer service requirements.

• Service costs increased by Ps. 3.6 million, or 9.9%, mainly as a result of higher electricity consumption due to expansions to our infrastructure, as per our master development programs.

• Other operating costs increased by Ps. 2.3 million, or 4.2%, as compared to the first half of 2006. This was mainly the result of the leasing costs paid to Shared Counter Spaces (CUTE).

The Company’s operating margin increased 3.7 percentage points, from 43.8% in the first half of 2006 to 47.5% in the first half of 2007. This increase was primarily a result of the increase in revenues and controlled operating costs. The EBITDA margin increased 2.2 percentage points, from 66.9% in the first half of 2006 to 69.1% in the first half of 2007.

Net income increased by Ps. 172.4 million, an increase of 44.9% when compared to the first half of 2006. Due to the aforementioned factors, net income before taxes rose by 22.9%. We also experienced a tax benefit of Ps. 19.0 million during the first half of 2007 due to a decline in our effective tax rate for the semester from 42.6% to 32.3%. This tax reduction was a result of the favorable ruling the Company received in 4Q06 regarding the asset tax treatment of the airports in Aguascalientes, Hermosillo, La Paz, Los Mochis, Manzanillo and Morelia as well as changes in the asset tax law for 2007.

- U.S. dollar figures were converted from pesos to U.S. dollars at a rate of Ps. 10.7901 per U.S. dollar (the U.S. Federal Reserve noon buying rate at June 29, 2007).

Workload units represent passenger traffic plus cargo units (1 cargo unit = 100 kilograms of cargo).

The Mexican Ministry of Communications and Transportation (SCT) regulates the majority of the Company’s activities through maximum rates, which represent the maximum aeronautical revenues allowed per WLU at each airport.

Regulated revenues for the second quarter of 2007 were Ps. 680.3 million, resulting in an average rate per WLU of Ps. 108.8. Regulated revenues accounted for 80.3% of total revenues for the quarter.

The Mexican Ministry of Communications and Transportation annually reviews our compliance with the maximum rates; to date, they have notified the Company that it complied for 2005, and while the review for 2006 compliance has already been initiated, the final notification of compliance for 2006 remains pending.

At the close of the second quarter of 2007, the Company maintained a balance of cash and cash equivalents of approximately Ps. 815.4 million; this amount already reflected the dividend payment to shareholders in May 2007 for Ps. 815.0 million (historical pesos). The remaining balance will be used for the operation of the airports, as well as to enable us to fulfill our investments under our master development programs in 2007.

Other current assets at the close of the second quarter 2007 included the benefit from the final resolution of the manner of calculating asset tax at some of our airports, which amounted to Ps. 209.6 million.

At the close of the second quarter 2007, the Company’s principal assets consisted of the concessions, with a balance of Ps. 17,289.1 million, rights to use airport facilities, with a balance of Ps. 2,359.0 million and fixed assets of Ps. 2,460.6 million. These represented approximately 68.0%, 9.3% and 9.7% of total assets, respectively.

During 2Q07, the Company invested Ps. 102.5 million, 29.7% more than what was invested in the same period of 2006.

These investments allow GAP to maintain airport facilities in excellent operating condition, while also complying with our obligations under the master development programs.

On April 20, 2007, the Company announced that Mr. Carlos Del Rio, the Company's chief executive officer, tendered his resignation as CEO of GAP in order to pursue other projects for ACS in his native Spain. His resignation became effective July 1, 2007, and Mr. del Rio continued to fulfill his duties as chief executive officer until that time. Mr. Jorge Sales Martinez assumed the role of Chief Executive Officer on the above-mentioned date.

In April 2007, at the annual general shareholders’ meeting, the Company agreed to pay a dividend in the amount of Ps. 1,140.0 million, of which Ps. 815.0 million was paid on May 18, 2007, while the remaining Ps. 325.0 million will be paid in October 2007.

On March 27, 2007, the Company announced that the Mexican Ministry of Communications and Transportation (SCT) suspended the commercial operations of Lineas Aereas Azteca and granted the airline 90 days to correct its deficiencies prior to resuming its operations. Of the routes operated by Lineas Aereas Azteca at GAP’s airports, none were operated exclusively, or dominated by this airline. As a result, most of the impact from the suspension will be quickly absorbed by the existing flights of other airlines that currently operate such routes.

	-	On December 14, 2006 the Company announced the favorable court decision and final notice reached by the appellate court of Mexico for the airports of Aguascalientes, Hermosillo, La Paz, Los Mochis, Manzanillo and Morelia. The Company obtained approval for our method of calculating the asset tax base taking into account only the strategic partner’s 15% ownership interest in the Company.

		To date the Company has requested a refund for the amounts paid from 2002-2006 for the airports of Aguascalientes, Hermosillo, La Paz, Manzanillo, Los Mochis and Morelia. As per April 18, 2007, the Aguascalientes’ local tax office turned down the Company’s request for this time period. Currently, the Company is appealing this ruling and expects that there will be a delay the recovery of this payment. The amount of the refund for the Aguascalientes airport is Ps. 27.1 million. In July 2007, the La Paz Airport received on behalf of the SHCP a Ps. 30.3 million refund for IMPAC’s miscalculation of the asset tax for the period of July 2003 to December 2006 period.

		On July 4, 2007, the local tax authorities of La Paz denied the refund of the amounts corresponding to the period of 2002 to June 2003. The Company will follow the applicable legal procedures in order to obtain these refunds, which will delay the payment of these amounts. The amount for this period is Ps. 10.4 million. The procedures in the remainder of the airports continue normally.

		With respect to the legal proceeding that is still in the Ninth Appellate Court of the Second Circuit, with regards to the airports of Guadalajara, Tijuana, Puerto Vallarta, Los Cabos, Bajio and Mexicali, the Company is still awaiting this decision.

	•	On July 19, the airports of Los Cabos, Puerto Vallarta, Hermosillo and Bajio signed mandate agreements with the financial institution that will grant the loans in 2007 of Ps. 330 million, Ps. 193 million, Ps. 44 million and Ps. 33 million, respectively; for 2008 of Ps. 273 million, Ps. 26 million, Ps. 17 million and Ps. 28 million, respectively, and for 2009 of Ps. 202 million, 8 million, Ps. 41 million and Ps.19 million, respectively. These loans will be used to finance the execution of its master development programs for those years. The above mentioned financial institution will commence its due diligence process so that this process can be concluded, the credit contracts can be signed and the resources can be made available by August 31, 2007. Once the Company has signed the contracts, we will notify the markets of the general conditions of these loans.

The Company anticipates the growth trend in domestic passenger traffic in 2007 to be above the historical average, driven mainly by a greater coverage of low-cost carriers within its airport network as well as a greater number of routes and frequencies by these airlines. This growth depends, however, among many other factors, including these airlines achieving their business plans and receiving delivery of new aircraft they have ordered, which, according to Mexican media, they expect to receive over the course of 2007.

We expect that total passenger traffic for the remainder of 2007 will increase between 8 and 10%; we expect domestic traffic to increase between 13 and15% and we expect international traffic to decrease between 2 to 4%.
