'In the context of these measures, an increase in cases of unruly or disruptive passengers should be expected, either prior to departure or in-flight. This may be due to passengers not wishing to sit next to each other or accusing each other of not following the rules. There is a strong potential for conflict if it is not managed properly. In the worst-case,panic could become quite a serious threat to flight safety –for example if there are significant displacements within the cabin. To address this, operators are invited to consider the raised likelihood of these factors within their procedures and training.'
