Stew­ardess la­dy: If there is a sud­den change in cab­in pres­sure, a mask com­part­ment above your seat will open au­to­mat­i­cal­ly. If this hap­pens, quick­ly reach for the near­est mask and pull it down firm­ly. Con­tin­ue to breathe nor­mal­ly. If you are trav­el­ling with a small child, or some­one who acts like a small child, please se­cure your mask and then as­sist them.
