Teniente Benjamín Matienzo International Airport — San Miguel de Tucumán, Argentina

Teniente Benjamín Matienzo International Airport commemorates an Argentine military aviator who died in 1919 attempting a pioneering flight across the Andes, and the facility bearing his name now serves San Miguel de Tucumán, capital of Argentina's smallest and most densely populated province. TUC functions as the principal air gateway to the country's fertile northwest, a region historically built on sugarcane cultivation and citrus agriculture that shaped Tucumán's identity as an early industrial center outside Buenos Aires. The city holds symbolic importance as the site where Argentina's declaration of independence was signed in 1816, commemorated today at the Casa Histórica museum. Domestic flights link Tucumán with Buenos Aires and other interior cities, supporting both business travel tied to agribusiness and visitors drawn to the nearby Calchaquí valleys.
