The increased service between the two cities will make things easier for Britons considering Dubai property investment.
This additional flight will mean consumers are able to fly between London and Dubai five days a week with a total of 26 services.
Paul Starr, commercial manager for Middle East operations at BA, said that Dubai continues to be an important market for the airline.
"We are adding a fourth daily Dubai-London flight, five days a week, from January due to the popularity of our existing three daily services," he commented.
"In a year in which commercial aviation has probably faced the harshest trading environment in history, we have nearly doubled our Dubai-London services in the last two months alone - I think that speaks volumes about how important the Dubai and wider Middle East market is to British Airways," Mr Starr added.
As part of its commitment to Dubai, British Airways announced earlier this year that its revamped business class, Club World, would be available on all winter flights between the emirate and London.
