British Airways said on Wednesday it would move its remaining long-haul flights to Heathrow's new Terminal 5 building in two phases before the end of the year.
In a joint statement with Spanish-owned airports operator BAA, the British carrier said it would transfer 30 more daily departures and arrivals to T5 from September 17, followed by a final 15 by the end of October.
It said earlier this month it would start moving a new phase of long haul flights to the new terminal on June 5, having delayed original plans amid the chaos that accompanied the terminal's opening at the end of March.
