Santorini International Airport — Santorini Island, Greece

Santorini International Airport, coded JTR, occupies a narrow stretch of land on the eastern side of Santorini, one of the most photographed islands in the Aegean Sea. A single runway handles a startling volume of seasonal traffic, as the island's caldera views, whitewashed villages of Oia and Fira, and volcanic beaches draw enormous crowds each summer. Capacity at JTR becomes a genuine bottleneck during peak months, with flight delays and packed terminals a familiar complaint among travelers arriving from Athens and dozens of European cities via charter and low-cost carriers. Santorini itself sits atop the caldera of a massive volcanic eruption that reshaped the island roughly 3,600 years ago, an event some scholars connect to ancient legends. Winter traffic drops off dramatically, leaving the airport comparatively quiet outside the tourist season.
