Turin Airport — Caselle Torinese (TO), Italy

Turin Airport, officially named Sandro Pertini after the Italian president who championed regional development, sits in Caselle Torinese a short drive north of the Piedmont capital. TRN grew alongside the city's automotive industry, historically linked to Fiat, and gained international attention when it handled the surge of visitors during the 2006 Winter Olympics hosted in Turin and the surrounding mountains. Today the single-terminal facility manages mostly domestic and European traffic, with low-cost carriers offering seasonal links to Mediterranean and ski destinations. Ground transport connects travelers to Turin's center in roughly forty minutes, and the airport remains a secondary but steady gateway compared to Milan's larger hubs. Its runway and apron were expanded in past decades to accommodate growing charter and holiday traffic serving the wider Piedmont region.
