Are you usually unconscious or physically impaired when flying? I have to admit after prolonged connection time and lounge access I may have been. ;-)
Wearing a mask should be required in every close proximity situation until the pandemic is under control and those who can't wear a mask should stay at home. The only peer reviewed study I was able to find about masks limiting O2, CO2, and tidal volume was a group of pregnant women fitted with a N-95 mask while under exercise. Wear a mask and don't kill your health care providers.
