re WH and Manchester, I'm only putting my 9 year old twins on this plane next Monday 17th unaccompanied, so perhaps I'll take some binoculars and see what BAs using! Argh.
I've done this route several times myself (and thanks BA for keeping it going and not just being a London airline, since some of us enjoy living North) and never had any problems. But perhaps with you sharp lot up front the passenegrs never realise??!
