SLF here... and I realize that I'll likely get deleted, before the lack of news worthy link does, but I sure long for the days when passenger decorum was the norm and not the exception.
I fly busines travel often. Fortunately, most of my flights have conducted themselves within the norms of domestic flight that I've come to know. It's the int'l ones that become questionable.
I'd gladly pay $100-200 more if it meant the difference between a pleasant flight and those whose behaviours are already questionable prior to boarding.
