SAO PAULO (AP) – The Brazilian government privatized operations at three of the nation's main airports on Monday, awarding $14 billion in contracts to three consortiums that will expand and run terminals amid booming demand and ahead of the 2014 World Cup.

Improving airports plagued with bottlenecks, long lines and poor infrastructure was a key promise the government made in its winning bid to host soccer's premiere event in 2014. Hundreds of thousands of fans will fly between the 12 host cities for matches.

Brazil's airports have buckled under demand that tripled in the past decade. In 2002, airlines flew 34.3 million passengers on flights originating in Brazil. That rose to 107.8 million last year, Brazil's civil aviation agency reported.

Top officials from FIFA, soccer's governing body, have consistently criticized Brazil for the lack of upgrades to the ailing air system. But the privatizations are aimed at quick improvements. The government is expected to soon auction the rights to run other airports, including Rio de Janeiro's international airport.

Some analysts see this as the first push by the pragmatic President Dilma Rousseff to address Brazil's infrastructure woes with the help of private capital, despite resistance from the base of her leftist Workers Party.

"The auctions should be seen as part of a broader, multifaceted effort to attract private capital to infrastructure in order to overcome acute bottlenecks in rail, roads, ports and civil aviation,'' the US-based Eurasia Group consulting firm wrote in a research note Monday. "If successful, the airport auctions could reinvigorate the push for concessions on other transport infrastructure sectors.''

Infraero, the state-run agency that has long operated airports, retains a 49 percent stake in the privatized airports, which include the nation's busiest airport in Sao Paulo, along with those in the capital Brasilia and in the city of Campinas in Sao Paulo state.

Together, the three airports are responsible for 30 percent of Brazil's passenger traffic.
