I just finished spending 7 hours on a commercial airliner with so many peeps with masks on I thought I woke up in a hospital. Do some research on these things and you'll find all they do is protect others from you spitting on them. The Coronaviris has no known means of transmission yet.
I had an interesting experience yesterday with my wife caughing and the girl seated next to her went ape shit. She got so upset she left her seat and took 2 others with her leaving us with a nice empty row on a long flight.
On her way out she wound up standing next to my wife for 5 minutes while wating to get off the plan. It was a very nice flight.
