What does it take to keep wearing a mask on a flight, just to be safe?

With regard to Hayley Skirka’s article US CDC says travellers should keep wearing face masks on flights (May 4): honestly, it isn’t that hard to keep a mask on when surrounded by so many people, and with such high chances of catching something, as at airports and on planes. One would imagine that people would want to take precautions after what we’ve seen in the past two years, and counting.
