The Presidency is reassuring air passengers who use the Nnamdi Azikiwe International Airport that the reconstruction works on the runway of the Nnamdi Azikiwe International Airport, Abuja (NAIA) had fully commenced and would be completed within the stipulated deadline of six weeks.

A spokesman for President Muhammadu Buhari, Mr Garba Shehu, gave the reassurance on his Facebook page on Sunday.

It was an update on the level of work so far at the project site with pictorial reports and Mr Shehu said the contractor handling the project had been fully mobilized.

"The contractor handling the project, Julius Berger Nigeria Plc, is confident of delivering the runaway for use within six weeks.

"The contractor is fully mobilised at Abuja airport, it will be for six weeks. Please bear with us it’s in the interest of safety," he wrote.

On March 8, the Nigerian government closed the NAIA for six weeks to repair its runway and diverted the airport's operations to the Kaduna International Airport.

Few days after the closure of the Abuja airport, President Buhari, who had extended his stay in the UK on health grounds, returned to Nigeria on Friday using a military base – not the airport currently undergoing repairs, apparently avoiding the eyes of travellers and other hitches that his presence at the airport could have caused.

The Minister of State for Aviation, Senator Hadi Sirika, had temporarily moved his office to Kaduna following the closure of the Nnamdi Azikiwe International Airport, Abuja.

Sirika said the temporary relocation of his office was to help airlines and their passengers to have hitch-free movement for the next six weeks when all Abuja-bound flights would be re-routed to the Kaduna International Airport.

"This is to ensure smooth operations and achieve intended results," he said.

The News Agency of Nigeria gathered that about 4,300 out of the 8,694 flights to and from the Nnamdi Azikiwe International Airport, Abuja in the next six weeks may have been cancelled following the diversion of flights to the Kaduna International Airport.

Only the Ethiopian Airline out of the eight international airlines plying the Abuja airport agreed to use the Kaduna International Airport for the next six weeks.
