Marche Airport — Falconara Marittima (AN), Italy

Marche Airport, carrying the code AOI, sits 49 feet above sea level in Falconara Marittima, a coastal town in Italy's Ancona province, just northwest of the city of Ancona itself. Traffic here runs over one runway, blending scheduled passenger routes with general aviation and occasional cargo movements. Because Falconara Marittima sits so close to Ancona, the airport is commonly referred to simply as Ancona Airport by travelers and airlines alike, even though its official name reflects the wider Marche region it serves. AOI functions as that region's principal air gateway, well ahead of any of the smaller airfields scattered around it.
