Aviation unions on Wednesday shut down the Murtala Muhammed International Airport II (MMA2) in protest.
The unions are protesting over the alleged sack of some of their workers.
The protesting unions are the National Union of Air Transport Employees (NUATE), Air Transport Services Senior Staff Association of Nigeria (ATSSSAN) and the National Association of Aircraft Pilots and Engineers (NAAPE).
The protest has left passengers stranded as those about to catch early morning flights, and also airline officials with businesses in the terminal were denied access into the premises.
The protest also caused heavy vehicular traffic around the airport environment.
According to the management of the airport, the unions have defied court order restraining them from shutting down the airport.
The union executives, however, deny knowledge of any restraining order.
