BA, which dominated the North terminal when it first opened, will soon
be squeezed out of that terminal, into the older South terminal.

Which they must have inherited from the British Caledonian routes (the
takeover was almost the same month the terminal opened). BA subsequently
decided that its long-haul should be predominantly from Heathrow.
