Sauce Viejo International Airport () is an international airport in Santa Fe Province, Argentina serving the city of Santa Fe. The airport is southwest of Santa Fe.
The new airport was built in 2005. It has a terminal and parking space for 150 cars. The Sauce Viejo non-directional beacon (Ident: SVO) is located on the field.
The aerodrome is located 17 km southwest of the city of Santa Fe, alongside National Route 11 and the Rosario â Santa Fe Highway. It regularly operates domestic commercial flights to and from Aeroparque Buenos Aires, as well as private flights to various cities across the country. The airport was recently certified as an international airport.
Initially called Aeródromo Sauce Viejo, construction began in May 1954, with the main runway completed in December of that year and the terminal in June 1955. It was inaugurated on 9 December 1955, with AerolÃÂneas Argentinas flight 526, which connected Mendoza with Buenos Aires, making a stopover in Santa Fe. Years later, in 1975, the airport's only runway was expanded. At that time, seven weekly flights were scheduled, and there was the possibility of connections to Córdoba, Mendoza, and other destinations.
The passenger terminal covers an area of 3000 m<sup>2</sup> and has separate entrances for arrivals and departures, facilitating passenger traffic. It has a total of 3 gates, all with direct access to the runway.
A building is under construction within the premises for the Fire Extinction Service (SEI), which will make it the first airport in Argentina to have its own fire station.
It has a Federal Security Force, the Airport Security Police, known as the Sauce Viejo Operational Unit. In 2021, as part of a provincial infrastructure plan launched by the Santa Fe government under Omar Perotti, a renovation of the airport terminal began.
