Я не уверена только в одном. You must leave behind dangerous items (Вы должны оставить опасные предметы). Я поставила этот пункт перед сдачей багажа. Не знаю, насколько это правильно. Возможно, его надо поставить после security check. На случай, например, когда в ручной клади есть вещи, которые нельзя проносить в салон. Но вообще он ка бы и туда, и туда подходит.
