The first phase was related to Gov. Aluízio Alves International Airport in Natal. On August 22, 2011 its concession was won by the Consortium Inframérica, formed by the Brazilian Engineering Group Engevix (50%) and the Argentinean Group Corporación América (50%), which operates 52 airports in 7 countries. After the signature of the contract of concession, Inframérica Consortium was authorized to commercially explore the facility for 25 years (with one possible 5-year extension). As part of the concession agreement Infraero holds no shares participation in this facility.
