British Airways will begin flying three times weekly direct from London Heathrow’s Terminal 5 to Durban, starting on 29 October.
The service will be the only non-stop link between Europe and Durban and will be operated by the airline’s newest aircraft, the Boeing 787-8 Dreamliner.
The aircraft will arrive at King Shaka International in the morning and land back at Heathrow in the evening.
BA also flies twice-daily from Heathrow to Johannesburg and daily to Cape Town year-round.
It doubles the Cape Town schedule during the South African summer season and also adds three weekly flights from Gatwick.
The route expansion comes as British Airways rolls out a $6.1 billion, five-year customer investment plan, with a focus on excellence in the premium cabins.
On its South African routes it has already introduced new bedding and amenity kits in the Club World cabin by luxury lifestyle brand, the White Company.
The investment will also see a new Club World seat in future.
At Heathrow it has opened a First Wing check-in area with direct security and lounge access. Lounges around the world are being revamped, including in Johannesburg and Nairobi.
