Seriously? Still with the "other countries don't think masks work"? YES THEY DO. Western Europe, you won't be going anywhere in public unless you have a mask. I am tired of this "other countries", "people tell me", "many people", line. Shut up unless you have facts.
Horse hockey! The airline said, you must wear a mask. Your pilot in command is THE LAW while you are flying. I suppose they could just kick you off the flight, parachute optional, if you don't want to follow the rules...
