Arturo Merino Benítez International Airport

The demands of the growing metropolitan area of Santiago and the need for modern, jet-era airport facilities, which could safely accommodate both domestic and intercontinental flights, drove the need to relocate the Chilean capital's principal airport from Los Cerrillos Airport (ICAO: SCTI; IATA: ULC) in the denser southwest metropolitan region of Santiago to the more rural northwest metropolitan area.

Construction of the original terminal building, the eastern runway (17L/35R), control tower, east apron and cargo facilities commenced in 1961. On February 2, 1967, the airport was commissioned Aeropuerto Internacional de Pudahuel, due to its location in the municipality of Pudahuel. On March 19, 1980, the airport was rechristened Arturo Merino Benítez International Airport in honour of the founder of the Chilean Air Force and Chilean carrier LATAM Chile.

The facility was expanded in 1994 with a new international terminal that covered 90,000 square meters, inspired by the architecture of Marseille Provence Airport in France. The building is located between the two parallel runways. This expansion added a new control tower, jetways, a duty-free zone, hotel, and greater parking area. The old terminal was used for domestic flights until 2001, when all passenger operations were merged into the same building.

In 2000, Lan Chile joined Oneworld, making of Arturo Merino Benitez Airport a main hub for the alliance, its first one in Latin America and its second in the Southern Hemisphere (after Qantas' Sydney Kingsford Smith International Airport in Australia). As of April 2014, 71% of international and 75% of domestic passengers were carried by Oneworld member airlines. During the 2010 Chile earthquake, the passenger terminal building suffered internal damages and the collapse of a pedestrian bridge between the vehicle ramp and the departures area. Nevertheless, both runways and control tower were unharmed, allowing the realization of a massive humanitarian air-bridge held by the Chilean Air Force to Concepción, Chile (Carriel Sur International Airport), close to the most damaged area by this earthquake and subsequent tsunami. The airport authority had closed off all commercial flight operations after around 1200 UTC on February 27, resuming full operations on March 3, 2010.[8][9]

In 2011, IATA recognized the DGAC (Chile's provider of air navigation services) and SCL (Santiago Airport) with the Exceptional Recognition Award to the cooperative efforts of SCL and DGAC Chile that facilitated a quick recovery from the devastation that followed the Chilean earthquake on 27 February 2010. "Both airport and air navigation services were restored quickly with no impact on rates or charges for passengers or airlines. DGAC Chile and SCL are widely regarded as leaders in Latin America for efficiency, quality, and customer focus.[10]

Departure gates

In June 2011, Santiago International Airport received the Air Cargo Excellence Award, as the best Latin American Cargo Airport.[11]

Construction on Runway 17R/35L began in 2004 and opened to traffic in September 2005. However, within months defects were discovered and the runway required repairing, completed in January 2006. Unfortunately further study of the problem discovered that the initial repairs were insufficient, needing additional work. Finally, 17R/35L reopened for traffic in March 2007.

In 2008, the airport terminal reached its maximum design capacity of 9.5 million annual passengers, two years earlier than forecast, and with the repairs needed after the 2010 Chile earthquake, the Ministry of Public Works announced in 2012 that it would call for proposals for the expansion and administration of the airport, two years prior to the end of the contract with the current operator.

The ministry decided to investigate a new airport master plan instead of an expansion of the single passenger terminal building, as initially proposed by the current operator. The feasibility studies for this master plan cost 4,560 million Chilean pesos (US$9.4 million) considered in the 2011 fiscal budget.

For this new master plan, the Government hired the consultancy services of Aéroports de Paris Ingeniérie (ADP-I), the architecture, engineering and technical branch of the French airport corporation.[12]

The master plan took into account a capacity growth to 14 million annual passengers by 2014, thirty-four million by year 2034 and 50 million passengers by 2045. New detached passenger terminal buildings for international and domestic flights, additional commercial areas and the construction of a light railway connecting the airport with the Santiago Metro network were considered.[13]

In June 2013, the Chilean Ministry of Public Works started Phase 1 of the airport expansion.[14]

On February 4, 2015, the consortium "Nuevo Pudahuel", formed by French companies Aéroports de Paris (45%), Vinci Airports (40%) and Italian infrastructure company Astaldi (15%) won the bidding process to manage and develop the airport for 20 years since October 1, 2015. The main missions of the new administration will be "the renovation of existing installations with the redesign and extension of the current terminal; the funding, design and construction of a new 175,000-square-meter terminal which will increase the airport's capacity to 30 million passengers, with potential for expansion beyond 45 million; the operation and commercial development for the duration of the concession (20 years) of the main infrastructures: existing terminal and new terminals, car parks and future property developments. Building works will be executed by Astaldi (50% of conception-construction pool) and Vinci Construction Grands Projets (50%)".[15]

View of the domestic terminal

The terminal building, originally built for both domestic and international operations until 2021, has four levels:

• Ground floor: Arrivals, duty-free shop, baggage claim, transport services, parking areas, hotel access.
• First floor: Administrative offices, VIP lounges (access through the second floor).
• Second floor: Departures, check-in & baggage drop off hall, shops, restaurants, boarding gates.
• Third floor: Restaurants and VIP check-in areas (LATAM).

Terminal 1 hosts a bank office, Chilean Automobile Club, telecommunication companies (Claro, Movistar and Entel PCS), pharmacy, travel agencies, airlines offices, insurance offices and a police station (Carabineros de Chile).

The new international terminal covers more than 200,000 square meters. It involved an investment of $900 million USD. Construction started in August 2016 and ended in March 2021, increasing the total airport capacity from 16 to 30 million passengers per year. The core of the new terminal consists of a central processor (T2M) where passengers undertake arrivals and departures procedures as well as four piers where the departure lounges are located.

Pier C is a structure that has 10 boarding bridges, on a surface of more than 23,700 square metres of serviceable area, and 27,600 square metres of constructed area. It opened its doors in December 2018. Its internal design and green colour are inspired by Easter Island (Rapa Nui). The pier has more than 1,900 square metres dedicated to retail space, of which 250 square metres are allocated to Duty Free areas. The structure also has PRM assistance zones.

Pier D features 10 loading bridges covering an area of over 22,000 square meters and opened its doors in July 2021. Passengers are able to reach Pier D directly from the "Main Unit" (T2M) and it is a place for both domestic and international flights. The building also features commercial and gastronomic premises, a playground, an area for art and culture and aid stations for passengers with reduced mobility. The space is inspired by the Atacama region, mirrored in its range of warm colors and panels inspired by the light, energy and strength of northern Chile.

Pier E has 12 passenger boarding bridges on a surface of more than 26,700 square metres and opened during the second half of 2019. The pier has more than 1,600 square metres dedicated to retail space, of which 250 square metres are allocated to Duty Free areas. The structure will also have PRM assistance zones. It has been inspired by the region of Los Lagos (Lake District), and this is reflected in the structure's blue palette and decorative panels.

Pier F has 10 loading bridges in an area of over 21,000 square meters and was opened in July 2021. Passengers reach pier F directly from the "Main Unit" (T2M) and it is entirely used for international flights. The building also features commercial and gastronomic premises, a playground, an art and culture area and aid stations for passengers with reduced mobility. The space is based on Patagonia, mirrored in its range of cold colors and panels inspired by the freshness, cleanliness and calm of southern Chile.

Costanera Norte Expressway

Arturo Merino Benitez is about 17 kilometres (11 mi) by car from Santiago's city center. The airport is well served by the six-lane expressway Costanera Norte (Exit # 31), which crosses through the city from West to East bordering the Mapocho river, while it is also well connected to the West, North and North-East of Santiago by the Vespucio Norte Express Ring motorway (Exit # 18).

There are two official airport taxi services: Taxi Oficial and Taxi Vip. TransVip shuttle services reach most of Santiago's hotels, business and residential districts.

Buses at the Departures Level

Centropuerto buses connect the airport with Los Héroes station of Santiago Metro. Their frequency is every 10 minutes during weekdays and 15 minutes during weekends. Turbus offers a similar service to its Alameda terminal. Both these services stop at the Pajaritos metro station/bus terminal on the way.

Car rental services are available from the airport.[26]
