Santiago is set to become the first South American capital with an integrated underground train service connecting directly to airport terminals. According to transport authorities, the Línea A Metro extension to Arturo Merino Benítez Airport is scheduled for official inauguration in 2032.
How will the new airport Metro line operate?
The project consists of a 6.5-kilometer underground route that will utilize light trains to connect the urban network to the airport. The service will feature two terminal stations, Huelén and Aeropuerto, along with two construction shafts and dedicated mechanical workshops.

Passengers will access the extension by transferring at the future Huelén Station on Line 7, which is currently under construction in the Cerro Navia commune near the Hospital Félix Bulnes. Once on the line, the trains will travel directly to the airport terminal without intermediate surface stops.
- Speed: Trains are expected to reach speeds of up to 80 kilometers per hour.
- Technology: The convoys will feature 100% autonomous driving, air conditioning, and universal accessibility.
- Safety: The stations will include platform doors to prevent passengers from falling onto the tracks.
What are the projected costs and travel times?
The complete journey between the urban Metro network and the airport is expected to take only 7 minutes. This offers a significant alternative to current transit methods, such as taxis or ride-sharing applications, which can cost between $15,000 and $25,000.
The estimated fare for this special segment is approximately $3,000 pesos. This service will be fully integrated into the existing Metro de Santiago and RED Movilidad systems, allowing passengers to use current digital and physical validation methods.
What is the scale of the project?
Originally conceived as a private concession through the Ministerio de Obras Públicas (MOP), the project is expected to handle a projected flow of 9.5 million passengers annually. This expansion is intended to change how travelers plan transit for both business and leisure.
