There’s also another issue which everyone hopes will not present itself as a problem when things start to show a degree of normality (hopefully not too long) and that’s gonna be safety/ currency on type. Obviously start at the top with the Top 100 Airlines as an example, work way down to corporate and rotary wing then GA will be the very last on the pecking order.
I have not forgotten the cabin crew nor engineers maintenance folk either
I doubt it will be the complete death of aviation ...but could take a year or two to come up to speed ?
All the best and lest get through this together.
Cheers
