There are 54 airports in Nigeria; the principal airports are Murtala Muhammed International Airport in Lagos and Nnamdi Azikiwe International Airport in Abuja. Three other international airports are Mallam Aminu Kano International Airport in Kano, Akanu Ibiam International Airport in Enugu and Port Harcourt International Airport in Port Harcourt. As with other transportation facilities, the airports suffer from a poor reputation for safety and operational efficiency.
