The lateness of the gate numbers' appearences on the boards has cought me out occasionally - sitting in GC N, watching the screen and seeing A21 flash up almost symultaniously with 'last call'... Or worse, my children were ambling around 'A' terminal (because the BRU flight always goes from there (ha ha) and then having to 'leg-it' to the B terminal at short notice...

A little more notice would be nice, but I realise that things change, beyond BA / BAA's control.
