Putumayo Airport (IATA: PYO, ICAO: SEPT) is a small regional airport serving Puerto Putumayo, a remote town in the Sucumbíos Province of Ecuador, near the border with Colombia and Peru. The airport provides essential air connectivity to a region where road access is extremely limited, making aviation a critical link for residents and government services. The facility handles light aircraft and small regional turboprops, supporting local communities, oil industry personnel, and occasional government operations. Given the remote and frontier nature of the area, the airport sees limited scheduled commercial traffic and primarily serves charter and general aviation flights. Puerto Putumayo sits within Ecuador's Amazon basin, and the airport reflects the infrastructure challenges typical of remote Amazonian settlements. Connectivity to larger hubs such as Quito or Lago Agrio is the primary purpose of operations at this facility.
