Traffic in Brazil is heavily concentrated: São Paulo/Guarulhos International Airport (GRU) alone handles about 43.0 million passengers a year, roughly 49% of the 88 million across the 4 airports listed here. That pattern is typical of a country with one dominant hub carrier feeding a single gateway.
Between them these airports operate 8 runways serving 3 cities, all on a single national clock. The highest field is Brasília - Presidente Juscelino Kubitschek International Airport at 3,497 ft, where thinner air lengthens the takeoff run. Every airport below links to a live map of aircraft observed within available ADS-B coverage around the field.
The next airport in the ranking is São Paulo/Congonhas Airport (CGH) at about 21.0 million passengers. The gap to GRU is 22 million, while the three busiest airports account for roughly 91% of traffic represented by this list. Most listed traffic is therefore concentrated at the top of the network.
The airports are spread across roughly 8 degrees of latitude and 5 degrees of longitude. The network is geographically compact enough that most domestic sectors remain comparatively short. Field elevations span 3,486 ft, so crews can move between very different takeoff-performance conditions. The average across this selected set is 2.0 runways per airport.
Read airport by airport, the selected Brazil network is not interchangeable: São Paulo/Guarulhos International Airport (GRU) has 2 runways and about 43.0 million annual passengers, São Paulo/Congonhas Airport (CGH) has 2 runways and about 21.0 million annual passengers, Brasília - Presidente Juscelino Kubitschek International Airport (BSB) has 2 runways and about 16.0 million annual passengers and Santos Dumont Airport (SDU) has 2 runways and about 8.0 million annual passengers. Those differences matter when comparing a live map. A larger passenger total indicates schedule scale, while runway count describes physical layout; neither number by itself proves how delayed, connected or operationally efficient an airport will be on a particular day.
