Piedras Negras International Airport — Piedras Negras, Mexico

Piedras Negras International Airport (PDS) serves the border city of Piedras Negras in Coahuila, Mexico, directly across the Rio Grande from Eagle Pass, Texas. The airport primarily handles domestic flights connecting Piedras Negras to major Mexican cities, supporting the region's manufacturing and maquiladora industry as well as cross-border trade traffic. Despite its international designation, PDS sees modest passenger volumes, with many travelers in the area opting to cross the border and use airports on the Texas side instead. The city's economy is closely tied to its twin-city relationship with Eagle Pass, and PDS reflects that binational dynamic by serving business travelers connected to industrial and trade activity along this stretch of the US-Mexico border.
