Chachoán Regional Airport (IATA: ATF, ICAO: SEAM) serves Ambato, the capital of Tungurahua Province in the central Andean highlands of Ecuador. Situated at an elevation of approximately 2,581 meters (8,468 feet) above sea level, the airport operates under challenging high-altitude conditions typical of Andean airports. The airport primarily handles domestic flights connecting Ambato with other Ecuadorian cities, serving the regional commercial and agricultural economy of Tungurahua Province. Ambato is known as an important trade and textile center, and the airport supports business and passenger travel in the region. Due to its limited infrastructure and runway capacity, Chachoán handles a relatively modest number of flights compared to major Ecuadorian hubs such as Quito or Guayaquil. Operations have historically been limited, and scheduled commercial service has varied over the years.
