 It held the name "WAAC Nigeria" until 1971, when it was rebranded to the name it had until it ceased operations in 2003.
 The government of Nigeria owned a majority of the airline (51%) until 1961, when it boosted its participation in the company to 100% and made it the country's flag carrier.
 At the time of dissolution, the airline's headquarters were at Airways House in Abuja.
 Operations were concentrated at Murtala Muhammed International Airport and served both domestic and international destinations mainly concentrated in West Africa; the network also had points in Europe, North America and Saudi Arabia.

 The museum is funded by entrance fees to the museum and by renting out the aircraft interiors for corporate functions.
 The flying aircraft of the museum are known as the South African Historic Flight collection, the aircraft are owned by the South African Airways Museum Society and are leased to the company Skyclass Aviation, who operate them for charter usage.
South African Airways Flight 406, also known as the Rietbok Crash, was a scheduled passenger flight on 13 March 1967 that crashed into the sea on approach to East London, South Africa.
 All 25 passengers and crew on board were killed.
 The air accident report speculated, without supporting evidence, that the pilot of the plane suffered a heart attack while on approach and the co-pilot was unable to regain control of the aircraft.
 Like the crash of South African Airways Flight 295 two decades later, there was, and still is great contention about the ultimate cause of the aircraft accident.
