Coronavirus is not airborn its droplet/surface transmission. This is the same way the flu is transmitted.
Airborne diseases would be things like the measles or tuberculosis. If this disease was airborne transmitted we would be royally fucked.
Droplet disease =you're on a plane and someone sneezes and anyone in the immediate area (ie where the droplets are in the area where the droplets get aerosolised) is at risk
Airborne = someone on an airplane has tuberculosis, the air on the whole plane circulates, and everyone on the entire plane is at risk for tuberculosis.
Moral of the story is airborn would be way way worse
