Quote: "I was forever hopeful that with allthe extra slots BA now has, and the chronic lack of space at T5, that the whole BA domestic operation might have been shifted back to the old BMI area at T1."
Won't happen, LHR-1 is due for demolition when the new LHR-2 opens (next year?).
The whole point of LHR-5 was to bring all of BA and one world under one roof. Pity it wasn't built big enough! That's why part of BA is at LHR-3 with one world.
Before, BA were at LHR-1 and LHR-4, now they're at back at LHR-1, LHR3 and LHR-5. Dear oh dear.
