The flight from Montevideo's Carrasco International Airport to Buenos Aires Ezeiza International Airport is one of the shortest international routes in South America, yet it connects two of the continent's most captivating capital cities. Covering roughly 200 kilometers across the wide mouth of the Río de la Plata, this journey takes just under an hour in the air, making it a convenient option for travelers who want to experience both sides of the river without committing to a lengthy ferry crossing. The route between Montevideo and Buenos Aires is served by several carriers, including Aerolíneas Argentinas and LATAM Airlines, with multiple daily departures offering flexibility for both business travelers and tourists. Some passengers opt for the Buquebus ferry service instead, but flying saves considerable time, especially when heading to destinations beyond Buenos Aires that require a connection through Ezeiza. Despite the short flight duration, the experience is pleasant. Aircraft on this route tend to be smaller regional jets, and window seat passengers on clear days can enjoy sweeping views of the estuary below, one of the widest rivers in the world. There is no significant turbulence to worry about, and the brief cruising altitude means the flight barely levels off before beginning its descent. Buenos Aires is a rewarding destination year-round, but the most comfortable months to visit fall between March and May or September and November, when temperatures are mild and the city's parks and outdoor cafés are at their most inviting. Summer months from December through February bring intense heat and humidity, while winter in July and August can be gray and chilly, though still manageable. One practical tip for travelers flying from Montevideo to Buenos Aires Ezeiza: remember that Ezeiza is located about 35 kilometers southwest of the city center. If your final destination is downtown Buenos Aires, factor in at least an hour for the ground transfer, depending on traffic. Some travelers find it more convenient to fly into Aeroparque Jorge Newbery, the city's domestic airport located much closer to the center, when that option is available on connecting itineraries. Booking in advance is advisable during peak travel periods, particularly around holiday weekends and major events like Buenos Aires Fashion Week or the annual tango festivals. Prices on this route can fluctuate significantly, and midweek flights tend to offer better availability. Whether you are crossing the river for a weekend of steak and tango or connecting onward to Patagonia, this short flight opens the door to one of South America's most dynamic cities with minimal effort.
