Monte Caseros Airport — Monte Caseros, Argentina

MCS is Monte Caseros Airport, serving the town of Monte Caseros in Corrientes province, northeastern Argentina, near the border with Uruguay along the Uruguay River. This is a small regional airport primarily used for general aviation, agricultural flying, and occasional government or charter flights, reflecting the town's modest size and rural surroundings dominated by rice, citrus, and cattle farming. Monte Caseros has historical significance in Argentine history, having given its name to an important nineteenth-century battle, though the modern airport itself has no connection to that era. Scheduled commercial service to MCS has historically been limited or nonexistent, with most regional travelers instead relying on road connections to larger Corrientes or Entre Ríos cities for onward air travel.
