Santiago Metro to Airport: Line A Opening Date, Fares & Station Guide
City of Santiago Launches Metro Line to International Airport, Aiming to Ease Travel Congestion
On June 29, 2026, Santiago, Chile, officially opened its Metro Line A extension to the Arturo Merino Benítez International Airport, marking a pivotal shift in the city’s urban mobility strategy. The project, which includes 10 stations and a fare of 800 Chilean pesos (approximately $1.10 USD), is expected to reduce traffic congestion and improve connectivity for 1.2 million daily commuters, according to El Mostrador.
What’s the Timeline for the Metro Line A Extension?
The Metro Line A extension, which connects the airport to the city center, was initially announced in 2018. Construction faced delays due to funding disputes and environmental reviews, but officials confirmed its completion by the end of 2026. The line will operate from 5:30 AM to 12:30 AM, with trains departing every 10 minutes during peak hours, as reported by the Santiago Metropolitan Transport Company (METRO).
“The completion of this line is a milestone for Santiago’s infrastructure, but we must remain vigilant about long-term maintenance costs,” said María González, a transportation analyst at the University of Chile. “The city’s population is projected to grow by 15% by 2030, and this project alone won’t solve all mobility challenges.”“
How Does the Fare Structure Work?
The fare for the Metro Line A extension is set at 800 pesos, a flat rate for all passengers regardless of distance. This pricing model aims to encourage public transit use over private vehicles, aligning with Chile’s national sustainability goals. However, critics argue that the cost may still be prohibitive for lower-income residents, particularly those traveling from peripheral neighborhoods.
“While the fare is reasonable, we need to ensure that subsidies or discounted passes are available for vulnerable groups,” said Congressman Luis Fernández, who sponsored a 2025 bill to expand public transit affordability. “This project is a step forward, but equity must remain a priority.”“
Which Stations Are Included in the New Line?
The Line A extension features 10 stations, including key hubs such as Terminal Turístico, Plaza de Armas, and Aeropuerto Internacional. These stations are equipped with modern amenities, including escalators, digital signage, and improved accessibility for people with disabilities. The airport station, designed to handle 15,000 passengers per hour, includes direct connections to domestic and international terminals.
The expansion also integrates with Santiago’s existing metro network, allowing seamless transfers to Lines 1, 2, and 6. This integration is expected to reduce travel times between the airport and central Santiago by up to 40%, according to METRO’s internal projections.
What Are the Broader Implications for Santiago’s Economy?
The new metro line is anticipated to boost Santiago’s economy by improving access to the airport, a critical gateway for tourism and business. A 2025 study by the Chilean Economic Development Agency (CORFO) estimated that enhanced airport connectivity could generate $2.3 billion in annual economic activity by 2030. However, local business owners in peripheral areas have expressed concerns about potential gentrification and rising property costs.
“This project benefits the city as a whole, but we must address the risks of displacement for long-time residents,” said Ana Martínez, a community organizer in the La Florida district. “We need policies that protect affordable housing and support small businesses.”“
How Does This Compare to Similar Projects in Other Cities?
Santiago’s metro extension mirrors similar projects in cities like Mexico City and São Paulo, which have also prioritized airport connectivity to stimulate economic growth. However, Santiago’s approach differs in its emphasis on affordability and integration with existing transit systems. For example, Mexico City’s Metrobús system charges higher fares, while São Paulo’s airport links require separate tickets, according to a 2026 report by the International Association of Public Transport (UITP).
The project also aligns with global trends in sustainable urban planning, such as the United Nations’ Sustainable Development Goal 11, which calls for “sustainable cities and communities.” Santiago’s focus on reducing car dependency through public transit reflects this international framework.
What Challenges Remain for the Metro Line A?
Despite its benefits, the project faces ongoing challenges, including the need for regular maintenance and the potential for overcrowding during peak travel periods. METRO has allocated $150 million for initial maintenance over the next five years, but experts warn that long-term funding may be uncertain. Additionally, the line’s reliance on a single route could create bottlenecks if other parts of the metro network fail to expand.
“This is a significant achievement, but it’s only one piece of a larger puzzle,” said Dr. Carlos Ramírez, an urban planner at the Pontifical Catholic University of Chile. “Santiago
