What I am worried about is that we see the imposition of aviation specific health care theater just like the current joke of airport security which is really just security theater; that is measures designed to make people feel better but don't actually do much to make travel safer.
Society seems to be getting worse and worse at making rational risk-reward decisions. Half filling airliners means air travel will only be available if you are rich, and IMO is policy madness disadvantaging whole segments of the population for virtually no real gain.
The bottom line is that air travel, especially international air travel is the primary means contagious diseases like the Corona virus spreads, so what are the procedures to put in place to make sure people who are sick don't get on airplanes ?
