If you beat it into people enough, most of them will probably remember. Where's the life vest? Under the seat, of course. Most people could tell you that in their sleep. Yet, do they study airplanes? No, they just hear that every single time they take off. Add in a couple scenes in spy thriller movies of Cary Grant or George Clooney smacking someone in a burning plane and shouting "Leave your luggage behind!", and you could probably cement it pretty good. It's pretty fascinating how quietly some things transition from "novel" to "common knowledge" inside your head.
