The airline is set to launch several new international routes in 2025, including connections to Brazil, Chile, and the United States, while also increasing capacity on some existing flights. The resumption of the direct flight between Córdoba and São Paulo on October 26, 2025, is expected to increase accessibility to Argentina’s interior, benefiting both business and leisure travelers.

This new route, which will operate daily, is a direct response to the growing demand for connectivity between Argentina and Brazil. It will provide an essential link for those traveling between these two nations for tourism, trade, or academic purposes. Moreover, LATAM Airlines has announced the restoration of direct flights from Rosario to São Paulo, beginning on December 30, 2025, offering four weekly departures. This development is part of LATAM’s broader strategy to increase its market share in Argentina and South America.

Additionally, LATAM Airlines is expanding its seasonal services to Florianópolis, Brazil. Beginning in January 2026, the Buenos Aires (Ezeiza) to Florianópolis route will operate daily during the summer, catering to both tourists and business travelers looking to explore Brazil’s vibrant coastal city. These routes will provide easy access to South America’s main tourism hubs, contributing to the overall expansion of Argentina’s international tourism sector.

Domestic Aviation Growth

Alongside international growth, Argentina is also focused on bolstering its domestic aviation routes. The government has worked with local airlines to improve connectivity between Buenos Aires and various domestic destinations, ensuring that regions such as Mendoza, Córdoba, Tucumán, and Ushuaia are easily accessible. These steps are designed to facilitate regional tourism while also fostering business opportunities and promoting cultural exchanges across Argentina’s vast landscape.

Rail Infrastructure: High-Speed Projects and Regional Connectivity

Buenos Aires-Rosario-Córdoba High-Speed Railway

In the rail sector, one of Argentina’s most ambitious projects is the construction of a high-speed railway that will connect Buenos Aires, Rosario, and Córdoba. This state-of-the-art railway, set to be operational by late 2025, is expected to reduce the travel time between these major cities by up to 50%. Currently, travel between Buenos Aires and Rosario takes several hours by car, but with the high-speed rail, this journey will be completed in just 85 minutes.

This transformative railway will use electric trains that can travel at speeds of up to 320 kilometers per hour, ensuring a smooth and rapid ride for passengers. The project also includes the construction of 55 kilometers of double-track between Buenos Aires and Rosario, which will facilitate high-speed operations and increase the overall capacity of the network. This high-speed rail is expected to improve economic exchanges between the major cities, boost tourism, and reduce the environmental impact of travel by providing a sustainable and efficient alternative to road transport.

The Córdoba section of the project will allow travelers to continue their journey from Rosario to Córdoba, with the entire trip taking just under three hours. The rail system will be integrated with Argentina’s existing transportation networks, making it easy for passengers to transfer between trains, buses, and planes, thus enhancing overall connectivity across the country.

Belgrano Sur Line: Extension and Regional Connectivity

The Argentine government has also been focused on extending regional rail services, especially in Buenos Aires province. The Belgrano Sur Line, which connects Buenos Aires with various towns in the southern part of the province, is undergoing significant upgrades. This extension includes the reopening of the González Catán to Villars branch and the addition of new services to other towns in the region, including Navarro. This project is aimed at improving mobility for local commuters and supporting regional economies by providing better access to Buenos Aires’ central business districts.

These upgrades are expected to provide a vital transport link for thousands of residents living in the southern suburbs of Buenos Aires, improving their access to employment, healthcare, and education facilities.
