Santos Dumont Airport (SDU) is one of the airports serving the Brazilian city of Rio de Janeiro. The airport is conveniently located about 2km from the city’s main business area and is the second serving airport behind Galeao International Airport. The airport handles around 3.2 million passengers a year (design capacity 1.8 million) and was originally the first airport of the city and used for international flights.

The airport has become increasingly congested over the years since it was first built 1937 by the architect MMM Roberto Doria-Baptista. The airport was constructed using reclaimed land on the coast (Guanabaro Bay) and has no room for further expansion, being surrounded on three sides with water.
