Termas de Río Hondo international Airport guide

The airport sits beside the Río Hondo Reservoir in Santiago del Estero Province, about 6 km west of the spa town of Termas de Río Hondo. It was built between 2010 and 2012 and opened on 24 July 2012. The first flight from Buenos Aires landed a month later.

A single asphalt runway, 01/19, is 2,500 m long. Runway 19 has a 350 m blast pad, and aircraft approaching or leaving to the south pass over the water. Aerolíneas Argentinas has flown the route to Buenos Aires–Aeroparque, with twice-weekly Embraer 190 service reported before the 2023 works.

The airport closed for 106 days in 2023 for expansion and reopened on 26 September 2023. The terminal grew from 1,700 m² to 4,350 m². Aeropuertos Argentina 2000 reported 78% more passengers in the first five months of 2023 than in the same period of 2019. Visitors mostly come for the thermal baths and for motorsport events at the nearby circuit.
