Almost every major passenger airline is retiring their 747s. The only ones still in the air are the 747-8, which are relatively new, and cargo planes.

Yeah, but it's not due to COVID-19. At most, COVID-19 accelerated it a bit, but four-holers were being phased out well before COVID-19.

It is in large because of the virus: the reduction in demand for flights made the 747 the prime target for retirement. Without a pandemic they would have been replaced gradually by newer planes, now they are just sitting unused so they are sold and scrapped.
