On April 26, 2011 it was confirmed that in order to speed-up much needed renovation and up-grade works, private companies would be granted a concession to commercially explore some Infraero airports in exchange for the implementation of those works. Listed airports included São Paulo/Guarulhos – Governador André Franco Montoro International Airport, Brasília – Presidente Juscelino Kubitschek International Airport, Campinas – Viracopos International Airport, and later Belo Horizonte – Tancredo Neves International Airport and Rio de Janeiro – Galeão/Antonio Carlos Jobim International Airport. The plan was confirmed on May 31, 2011 and it was added that Infraero would retain 49% of the shares of each privatized airport.
