The airport was built in the 1950s during the colonial era and was later upgraded and commissioned in 2001. It has one of the longest runways in Africa, measuring 4,725 kilometers.
It has a handling capacity of 2.5 million passengers per year and the government is planning to further upgrade and expand it to increase its capacity to 6 million passengers per year and turn it into a regional air transport hub.

He reaffirmed the government's commitment to the development of the country's air transport systems to facilitate economic development.
His government, he added, was taking steps to liberalize the country's air space in line with the Yamoussoukuro Decision of 1999.
The airport becomes the second to be renamed after the country's leaders following the Bulawayo Airport which was upgraded from domestic to international airport and renamed Joshua Mqabuko Nkomo International Airport after the late Vice President Joshua Nkomo in 2001.
In August, the government announced plans to build a $1bn university named after him.
