During covid my experience has been that manual safety demos seem to be the norm. However, the other evening (BWI-LHR) on a 787-8 it was the first time I can recall that a seperate 2nd demo had to be given to those in WT+. CW had 4 CC doing the demo - and presumably there must have been 4 in WT (two aisles x two in foward WT and 2 in rear WT cabins).
