The airline currently operates double-daily services to Cape Town between October and March, the busy Cape summer season, reverting to a daily service during the southern hemisphere winter, when demand typically declines.
Now it will expand the winter schedule, introducing three Boeing 777-200ERs a week each able to accommodate 219 customers in four cabins.
Announcing the new services, Gavin Halliday, British Airways' GM for Africa and Europe, said that since 2002 when it began campaigning for more summer frequencies to meet inbound tourism demand, the airline recognised the need to provide a year-round service to the Mother City.
"Operating year-round builds confidence in the route, not only amongst inbound tourists and business travellers, but also local customers wanting to visit London or travel onwards to the rest of our network.
"The fact that we are now able to bolster our winter schedule is testimony to this and the tremendous job which has been done to market Cape Town as a year-round destination as well as a business hub."
Halliday said that the new services are a significant investment for the airline and should contribute to regional economic growth.
"A 30% frequency increase is substantial and we will need to make a concerted effort to sell the additional seats. This means marketing Cape Town around our international network. As well offering more flights we're also investing in our products and services to encourage Capetonians to choose us for their business trips and holidays to London and beyond."
The airline is building a new lounge in Cape Town, modelled on its Galleries lounges at Terminal 5, which will be open by the end of the year. It has completed the roll-out of a new GBP100 million First cabin. In-flight catering has been improved in every cabin and a new in-flight entertainment system is being fitted to its new World Traveller and World Traveller Plus cabins. This gives customers 50% more choice of movies and doubles the range of television and radio options.
The Western Cape Minister of Finance and Economic Development, Alan Winde said: "The Western Cape remains a popular destination for visitors from the United Kingdom; last year we welcomed 181, 886 travellers from the UK. In addition, 17 000 readers of the Telegraph, which is one of the UK's most popular newspapers, voted Cape Town as their favourite worldwide city and South Africa as their third-favourite country.
"While we have a reputation as South Africa's leading leisure destination, we are also seeing a rise in business tourism. Ahead of the World Design Capital next year, the spotlight is on the Western Cape's creative sector and we expect scores of visitors to view the design showcase. The British Airways' capacity increase on this route speaks to strong consumer confidence in our destination and we look forward to welcoming a spike in travellers from the UK."
Wesgro CEO Nils Flaatten welcomed the increased flights, saying that research by the Western Cape's official tourism, trade and investment promotion agency had indicated that the London-Cape Town route held strong economic value for the Western Cape and neighbouring Eastern Cape.
"Business and leisure travellers from the United States are using London as a connecting flight into Cape Town and it is to British Airways' credit that it has answered the need for a year-round service to the destination. Wesgro and British Airways will continue to explore marketing options that will ensure that the demand for this new airlift capacity remains."
The Cape Town frequency announcement follows confirmation that British Airways will start operating its largest and most modern aircraft, the A380, to Joburg from mid-February next year.
