Why Airport Size and Traffic Matter
Big airports offer more than space. They support stronger connections. Large airports have more runways, terminals, and services. They make it easier for airlines to add new routes. More flights mean better options for travelers.
Some airports are built to serve millions of passengers. Others are spread out across huge areas of land. Either way, size helps improve airport flow, reduce delays, and boost comfort.
