Sadiq Abubakar III International Airport — Sokoto, Nigeria

Named for the Sultan of Sokoto, Sadiq Abubakar III, this airport carries the code SKO and serves a city that has functioned for two centuries as the spiritual center of Nigeria's Muslim north. Sokoto was the seat of the Sokoto Caliphate, founded in the early 19th century by the religious reformer Usman dan Fodio, and the sultan's palace remains a focus of religious authority across West Africa today. The airport connects this historic city, situated near the confluence of the Sokoto and Rima rivers close to the Niger border, with Abuja, Lagos, and other domestic hubs, since international scheduled service has stayed limited. Extreme heat defines much of the year here, at the edge of the Sahel, and dusty harmattan winds blowing from the Sahara periodically reduce visibility for arriving flights. For pilgrims, traders, and officials visiting the Sultanate, SKO remains the fastest and often the only practical route into the region.
