Diego Aracena International Airport — Iquique, Chile

IQQ sits amid the Atacama Desert's parched landscape, serving Iquique, a Pacific port city in one of the driest regions on the planet where some weather stations have recorded no measurable rainfall for years at a stretch. The airport lies a short distance south of the city, connecting it primarily to Santiago and other Chilean cities, with air travel serving as the practical alternative to the long desert highway drive along Chile's narrow north-south spine. Much of the airport's traffic ties to Zofri, a large duty-free trade zone established in Iquique that draws shoppers and business travelers from across northern Chile and neighboring Bolivia and Peru. The surrounding desert also holds abandoned nitrate mining towns and some of the world's clearest night skies, drawing a smaller but steady stream of tourists interested in astronomy and industrial history alongside the region's beach resorts.
