Nogales International Airport — Nogales, Mexico

NOG is Nogales International Airport, situated near Nogales, Sonora, Mexico, just across the border from its sister city of the same name in Arizona. Despite the 'international' designation, the airport primarily handles general aviation, cargo, and limited regional traffic rather than large-scale commercial passenger service, with much of the area's air travel instead routed through larger hubs like Hermosillo. NOG plays a role in supporting the cross-border trade and manufacturing activity, particularly maquiladora industries, that define the Nogales region's economy. The airport's proximity to the US border also makes it relevant for customs and binational commerce logistics.
