I know that some people are more private than others, and Delta respects that by only listing the first 3 letters of the persons last name on the upgrade list. My point is, addressing someone as Mr. or Ms. X is a nice touch, but doing it so loudly that the entire cabin hears it is not as optimal IMO.
