British Airways is to move its Vancouver flights from London Heathrow Terminal 4 to Terminal 1 on June 1.
It says the move will help ease congestion during the busy afternoon peak and will also help to smooth connections for many customers, including all UK regional customers, using Terminal 1 as a transfer point.
BA operates 13 flights a week from London to Vancouver during the height of the summer season.
The flights to and from Vancouver will stay in Terminal 1 until March 27 2008 when they will move to Terminal 5.
