Covid is the 'flu rebranded. People get the 'flu. Therefore people on a plane may have the flu.
Planes fly and can be said to have flew.

Masks will never stop the 'flu, but might stop dusts etc. But not any toxins in the air or the many plastics in planes (and possibly the food, but I haven't checked).
