British Airways flights from Belfast City Airport to London will land in Heathrow's Terminal 5 from October, the airline's chief executive has announced.
Its six daily flights to the London hub have been flying to Terminal 1 since BA took over the service from BMI in summer 2012.
The airline said the move would reduce connection time.
"This move reduces flight transfer time to just 60 minutes, and means that customers have a quicker journey through our dedicated terminal at Heathrow," chief executive Willie Walsh said.
Brian Ambrose, chief executive of George Best Belfast City Airport, welcomed the news.
"The transfer of all British Airways services from Belfast City to Heathrow's Terminal 5 will provide passengers from Northern Ireland with improved access to the airline's extensive global network at Heathrow's newest terminal."
BA said its Dublin service would also land at Terminal 5 from October.
