Usiminas Airport — Ipatinga, Brazil

IPN is the code for Usiminas Airport, serving Ipatinga in Brazil's Minas Gerais state, a city built largely around the massive Usiminas steel plant that gives the airport its name. The airport supports business travel tied to the steel industry, one of Brazil's largest, connecting Ipatinga to São Paulo, Belo Horizonte, and other major commercial centers. Ipatinga developed rapidly in the mid-20th century as a planned industrial city in the Rio Doce valley, and IPN reflects that industrial heritage as a corporate and cargo-oriented airport more than a tourist gateway. Flight schedules at IPN are shaped largely by demand from steel executives, suppliers, and industrial logistics rather than leisure travel.
