Traffic in Cuba is heavily concentrated: José Martí International Airport (HAV) alone handles about 4.0 million passengers a year, roughly 100% of the 4 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 6 runways serving 4 cities, all on a single national clock. Every airport below links to a live map of aircraft observed within available ADS-B coverage around the field.
The airports are spread across roughly 3 degrees of latitude and 7 degrees of longitude. The network is geographically compact enough that most domestic sectors remain comparatively short. Field elevations vary less dramatically than they do in the world's mountain-airport networks. The average across this selected set is 1.5 runways per airport.
Read airport by airport, the selected Cuba network is not interchangeable: José Martí International Airport (HAV) has 2 runways and about 4.0 million annual passengers, Antonio Maceo International Airport (SCU) has 2 runways and no comparable traffic figure, Juan Gualberto Gomez International Airport (VRA) has 1 runway and no comparable traffic figure and Frank Pais International Airport (HOG) has 1 runway and no comparable traffic figure. 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.
With 4 gateways in this data cut, the Cuba hierarchy is readable directly: HAV contributes 100% of the represented passenger total, SCU contributes 0% of the represented passenger total, VRA contributes 0% of the represented passenger total and HOG contributes 0% of the represented passenger total. That makes HAV the first gateway here without reducing SCU to a minor field, since its traffic is about 0% of HAV's.
The physical ranking differs from the traffic ranking: HAV has 2 listed runways, SCU has 2 listed runways, VRA has 1 listed runway and HOG has 1 listed runway. HOG is the highest of the group at 361 ft, against 210 ft at VRA. Those facts describe layout and setting, not a live capacity forecast; weather, active runway configuration and traffic flow still decide what a viewer sees on the map at a given hour.
