Nombre Total d'Aéroports dans le Monde
41,000
airports
There are approximately 41,000 airports worldwide, though fewer than 4,000 have scheduled commercial airline service.
Explication
The vast majority of airports serve general aviation, military operations, or private use. Only about 10% have commercial airline service with ticketed passengers. The United States alone accounts for nearly half the total with over 19,700 airports. Many developing countries have relatively few airports despite large populations, creating significant air connectivity gaps.
