Port Gentil International Airport — Port Gentil, Gabon

Gabon's oil economy runs largely through Port Gentil International Airport, coded POG, which sits on an island-like peninsula along the Atlantic coast serving the country's economic capital. Unlike Libreville, the political capital farther north, Port Gentil has no direct road connection to the rest of Gabon, which makes air and river travel essential and gives POG outsized importance relative to the city's modest population size. Oil company personnel, equipment charters, and helicopter transfers to offshore platforms account for much of the activity around the airport, alongside scheduled domestic flights to Libreville and a handful of regional West and Central African destinations. Dense equatorial rainforest and mangrove coastline surround the area, and Gabon's broader push to diversify its oil-dependent economy toward ecotourism, including nearby national parks, has slowly added a small but steady stream of leisure travelers to the airport's traffic mix.
