Maybe off-topic, but I'm going to jump in. Doesn't anyone feel creeped out by comments from FT posters, who make comments after obviously glancing at other passengers' boarding passes? I respect other people's privacy and expect they return the favor. Unless some volunteers their status, it should be just between them and the airline.

When someone earns their elite status, so be it. But you shouldn't be any less civil if it's different that yours.
