General Manuel Carlos Piar International Airport — Guyana City, Venezuela

General Manuel Carlos Piar International Airport, coded PZO, serves Ciudad Guayana, an industrial city formed from the merger of San Felix and Puerto Ordaz where the Caroni River meets the mighty Orinoco in eastern Venezuela. The airport takes its name from Manuel Piar, an independence-era general whose execution on Simon Bolivar's orders remains a debated chapter of Venezuelan history. Heavy industry defines the surrounding economy, with state-linked steel and aluminum plants drawing workers and cargo traffic through PZO for decades, even as output has fluctuated with Venezuela's broader economic troubles. Beyond industry, the airport has also functioned as a practical staging point for visitors heading toward Canaima National Park and the towering cascade of Angel Falls, the world's highest uninterrupted waterfall. Domestic connections link Ciudad Guayana to Caracas and other Venezuelan cities, though international service has diminished considerably over recent years.
