Ask yourself:
"What was more damaging/expensive to the local, state, national, and global economy? 9/11 or a multi-year pandemic?"
All the majors went under after 9/11 (except LUV).
I'm not optimistic for any of the majors to avoid a Ch 11 filing at the very least. One goes down, the rest will go like dominoes.
Or not. "It's different this time". Because we really, really want it to be. Yeah, that should do it.
