Osvaldo Vieira International Airport — Bissau, Guinea-Bissau

As the sole significant airport in Guinea-Bissau, OXB serves the capital, Bissau, connecting one of West Africa's smallest and least-visited countries to Lisbon, Dakar, and a handful of other regional points, largely through Portuguese carrier links tied to the country's colonial history. It bears the name of Osvaldo Vieira, a commander in the independence struggle against Portugal who was killed in the years following independence amid political turbulence that has repeatedly disrupted Guinea-Bissau's governance since then. Infrastructure at the airport has long suffered from underinvestment, a reflection of broader economic constraints in a country whose government has faced chronic instability, including multiple coups, since independence in 1974. Cashew exports, the backbone of Guinea-Bissau's economy, along with a modest flow of aid workers and diplomats, account for much of the airport's limited but essential traffic.
