The route currently operates once weekly and is codeshared with Angola Airlines. It is the only direct route between London and Luanda. The last outbound flight BA77 departs Thursday 7 June 2018. The last inbound flight BA76 departs Saturday 9 June 2018.
No reason has been given for the cancellation and the period of notice is very short. The route has been subject to occasional cancellations in recent weeks due to maintenance requirements of BA’s Boeing 787 Dreamliners.. The short notice period does suggest a degree of urgency to release a spare Boeing 787 for the summer.
It also has to be said that this development follows a number of suspended routes to Africa.
BA has previously suspended Dar es Salaam, Tanzania in 2012; Lusaka, Zambia in 2013; Freetown and Monrovia in 2014; and Entebbe, Uganda in 2015.
The main exception is South Africa where BA has recently announced Durban and an increase in flights to Johannesburg to 18 times weekly for the winter season.
If BA ever orders the Airbus A321 Long Range aircraft this may make some of these routes viable again. However, there is no sign of an imminent order.
