Traffic in Indonesia is heavily concentrated: Soekarno - Hatta International Airport (CGK) alone handles about 55.0 million passengers a year, roughly 100% of the 55 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, and the country spans 2 time zones, so a domestic flight here can change your watch. 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 12 degrees of latitude and 17 degrees of longitude. That geographic spread makes weather, daylight and local operating conditions materially different across the same national network. 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 Indonesia network is not interchangeable: Soekarno - Hatta International Airport (CGK) has 3 runways and about 55.0 million annual passengers, Hang Nadim International Airport (BTH) has 1 runway and no comparable traffic figure, Kualanamu International Airport (KNO) has 1 runway and no comparable traffic figure and Lombok International Airport (LOP) 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 Indonesia hierarchy is readable directly: CGK contributes 100% of the represented passenger total, BTH contributes 0% of the represented passenger total, KNO contributes 0% of the represented passenger total and LOP contributes 0% of the represented passenger total. That makes CGK the first gateway here without reducing BTH to a minor field, since its traffic is about 0% of CGK's.
The physical ranking differs from the traffic ranking: CGK has 3 listed runways, BTH has 1 listed runway, KNO has 1 listed runway and LOP has 1 listed runway. LOP is the highest of the group at 319 ft, against 23 ft at KNO. 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.
