Il Caravaggio International Airport — Orio al Serio (BG), Italy

Il Caravaggio International Airport, commonly called Orio al Serio after the town where it sits, serves Bergamo in Italy's Lombardy region at an elevation of 782 feet, with two runways supporting a very high volume of low-cost carrier traffic. The airport takes its formal name from the painter Caravaggio, who was born in the nearby town of the same name. Ryanair operates one of its largest Italian bases here, and the airport gets marketed heavily to travelers as a budget-friendly alternative to Milan's Malpensa and Linate airports, despite sitting roughly 30 miles from central Milan itself. That branding occasionally catches first-time visitors off guard when they discover their supposed Milan flight actually lands well outside the city, requiring a shuttle bus into town. Bergamo's own old town, a walled hilltop district known as Città Alta, draws a growing number of visitors who choose to stay in Bergamo rather than push on to Milan at all.
