Apparently the new BA LGW checkin is pretty much entirely self service. It's mentioned in this month's High Life rag. Its moving from Zones E and F (i.e. right in the centre of the check in hall) to Zone A.
Apparently the kiosks now print out your bag tags for you and the number of actual check in desks is vastly reduced. If I recall correctly there are 6 'baggage podiums', a few Customer Services Desks and a new Premium checkin area.
So now everyone (excepting EC Gold/Silv, First and Club) checks themselves in, tags their own bag and by the sounds of it pops it on the conveyor (or something similar) themselves. Much like the Qantas domestic terminal in SYD I imagine.
I'm not 100% certain of these details and its only what I can remember from glancing at the short article in High Life.
If its true, shouldn't the new slogan be: To fly. To self-serve?
