Traffic in Turkey is heavily concentrated: Istanbul Airport (IST) alone handles about 80.1 million passengers a year, roughly 100% of the 80 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 10 runways serving 4 cities, all on a single national clock. The highest field is Esenboğa International Airport at 3,125 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 airports are spread across roughly 4 degrees of latitude and 10 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 2.5 runways per airport.
Read airport by airport, the selected Turkey network is not interchangeable: Istanbul Airport (IST) has 5 runways and about 80.1 million annual passengers, Şanlıurfa GAP Airport (GNY) has 1 runway and no comparable traffic figure, Esenboğa International Airport (ESB) has 2 runways and no comparable traffic figure and Istanbul Sabiha Gökçen International Airport (SAW) has 2 runways 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 Turkey hierarchy is readable directly: IST contributes 100% of the represented passenger total, GNY contributes 0% of the represented passenger total, ESB contributes 0% of the represented passenger total and SAW contributes 0% of the represented passenger total. That makes IST the first gateway here without reducing GNY to a minor field, since its traffic is about 0% of IST's.
The physical ranking differs from the traffic ranking: IST has 5 listed runways, ESB has 2 listed runways, SAW has 2 listed runways and GNY has 1 listed runway. ESB is the highest of the group at 3,125 ft, against 312 ft at SAW. 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.
