The specific structure of the post virus air transport system is pretty much open, no carrier can survive in hibernation for months. So they all will need help to restart, which gives the governments lots of leeway. The carriers will reemerge, in some form and relatively quickly.

The global fleet has been getting substantially younger, courtesy of a decade of vigorous fleet renewal spurred by low interest rates. The system now has no replacement needs for several years.
Full Wings' perceptive comment just highlights another element which adds to the pressure on the manufacturers. Nobody will need more aircraft for some years. The industry may have considerably more adjustment in store.
