Edu Chaves Field — Guaratinguetá, Brazil

GUJ identifies Edu Chaves Field, the airport serving Guaratinguetá, a historic city in the Paraíba Valley region of São Paulo state, Brazil. The airport is named after Edu Chaves, a pioneering Brazilian aviator, reflecting Brazil's tradition of naming regional airfields after aviation figures. GUJ primarily supports general aviation, flight training, and small charter operations rather than scheduled commercial airline service. Guaratinguetá itself is known as the birthplace of Saint Frei Galvão, Brazil's first native-born saint, drawing religious pilgrimage tourism to the area. GUJ's modest scale mirrors many regional Brazilian airports that serve local aviation needs without significant scheduled passenger traffic.
