My experience with BA PE:
old worn out seats and IFE
no welcome drinks
no dedicated attendants
economy food thrown at you and presented with the same lack of interest shown to economy customers.
attendants go into hiding as soon as service is rushed through and only reappear for descent
You would think that considering the significant premium over a standard economy ticket, they could at least throw in some extra/ better quality food and service. I feel PE should be similar to business with a smaller seat, not economy with a bigger seat, maybe I expect too much.
