Traffic in Chile is heavily concentrated: Arturo Merino Benítez International Airport (SCL) alone handles about 26.2 million passengers a year, roughly 101% of the 26 million across the 3 airports listed here. That pattern is typical of a country with one dominant hub carrier feeding a single gateway.
Between them these airports operate 4 runways serving 3 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 next airport in the ranking is Mataveri International Airport (IPC) at about 0.2 million passengers. The gap to SCL is 26 million, while the three busiest airports account for roughly 100% of traffic represented by this list. Most listed traffic is therefore concentrated at the top of the network.
The airports are spread across roughly 13 degrees of latitude and 39 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 1.3 runways per airport.
Read airport by airport, the selected Chile network is not interchangeable: Arturo Merino Benítez International Airport (SCL) has 2 runways and about 26.2 million annual passengers, Mataveri International Airport (IPC) has 1 runway and about 0.2 million annual passengers and Diego Aracena International Airport (IQQ) 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 3 gateways in this data cut, the Chile hierarchy is readable directly: SCL contributes 101% of the represented passenger total, IPC contributes 1% of the represented passenger total and IQQ contributes 0% of the represented passenger total. That makes SCL the first gateway here without reducing IPC to a minor field, since its traffic is about 1% of SCL's.
The physical ranking differs from the traffic ranking: SCL has 2 listed runways, IPC has 1 listed runway and IQQ has 1 listed runway. SCL is the highest of the group at 1,555 ft, against 155 ft at IQQ. 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.
