Cagliari Elmas Airport — Cagliari, Italy

Cagliari Elmas Airport serves Cagliari, the capital of the Italian island of Sardinia. A single runway does the work here, just 13 feet above the water, covering the island's southern air traffic. As one of Sardinia's three main airports alongside Olbia and Alghero, Cagliari Elmas focuses on connections to mainland Italy and other European cities, particularly during the busy summer tourist season when visitors head to Sardinia's beaches. Coded CAG, the airport also serves as the primary year-round gateway for southern Sardinia, handling steadier business and resident travel compared with the more seasonally driven traffic at the island's northern airports. Cagliari itself ranks as Sardinia's largest city, sitting on the island's southern coast facing the Mediterranean, and the airport's single runway manages a mix of domestic Italian routes and a growing number of international connections despite a modest physical footprint compared with major continental hubs, a reminder that classification as a large airport rests on passenger volume rather than sheer runway count.
