The decision represents a U-turn for BA, which had earlier ruled out a dedicated check-in section for business-class passengers at the troubled terminal.
It is the latest setback for the flag-carrier following T5's disastrous opening in March, when thousands of items of baggage went missing after ground staff failed to operate the new systems correctly.
It has since put on hold a campaign, due to break earlier this year, showcasing the facilities at the beleaguered terminal.
Separately, BA's former commercial director, Martin George, is facing criminal prosecution relating to fuel-price fixing at the airline. George, and three other directors, could face up to five years in prison if found guilty of the allegations.
