El Dorado International Airport — Bogota, Colombia

El Dorado International Airport, coded BOG, serves Bogota, the capital of Colombia, from an elevation of 8,361 feet, making it one of the highest major international airports anywhere in the world. The thin air at this altitude affects aircraft performance and requires longer takeoff distances, which the field accommodates with two runways capable of handling wide-body jets fully loaded with fuel and cargo. BOG is the busiest airport in Colombia and a primary hub for Avianca, linking Bogota to destinations throughout the Americas and Europe. The terminal has undergone major expansion over the past two decades to keep pace with rising passenger numbers, reflecting Bogota's growth as a regional business and financial center for the Andean region. Beyond passengers, El Dorado also handles a significant share of Colombia's air cargo, including flower exports, one of the country's signature agricultural products, which leave this high-altitude hub for markets around the world every single day of the year.
