I rarely shy away from the "elitism" label, because it often goes along what is really "meritocracy," "accomplishment," and the like, which I think for positives. But "different rules or standards of conduct for a passenger in Y vs F or C" seems to me to give "elitism" a bad name. Is it because I am usually back in coach and expect the same "civility, avoiding obnoxious behavior, that sort of thing"? Indeed, maybe with less pronounced senses of entitlement the farther back one goes in the plane, there might be more civility.

(We both at about the same time analogized to restaurants. I wonder how many of the very best restaurants are indifferent to what their patrons wear. I don't see it as in the least "elitist" for them to charge high prices, like those exacted for F and C seats, and to have dress codes.)
