South African Airways has cancelled flights to Nigeria’s capital, Abuja, during six weeks of scheduled repairs to the international airport’s runway, AP news agency reports.
It joins British Airways, KLM and Air France in rejecting a government proposal to divert flights to northern Kaduna city and take passengers by bus on a journey of about 250km (155 miles) to Abuja, AP adds.
The news agency says this is a three-and-a-half-hour ride on a road notorious for accidents and kidnappings.
Officials say repairs, starting on 8 March, cannot be carried out at night because the runway at Nnamdi Azikiwe International Airport is in a shocking state of disrepair.
A South African Airways plane was damaged on landing there in August.
Other airlines have called it dangerous.
Lack of maintenance affects infrastructure across Nigeria.
