Rosario Islas Malvinas International Airport — Rosario, Argentina

Carrying the Malvinas Islands in its official name, a reference to Argentina's enduring claim over the Falkland Islands, ROS serves Rosario, the country's third-largest city and a major inland port along the Parana River. Rosario holds particular significance in Argentine history as the birthplace of revolutionary Che Guevara and, more centrally to national identity, as the site where General Manuel Belgrano first raised the Argentine flag in 1812, an event commemorated by the towering Monumento a la Bandera overlooking the river. The airport supports a mix of domestic routes connecting Rosario with Buenos Aires and other Argentine cities, along with a smaller number of regional international flights. Santa Fe Province's agricultural wealth, particularly soybean and grain exports moving through Rosario's river terminals, underpins much of the region's economic activity. ROS provides an important alternative to Buenos Aires's more congested airports for travelers focused on central Argentina.
