Just a demented silly thought
Perhaps they can look into what percentage of travel on airlines could be defined as Non-essential?
After all do you really need to go to Disney World or the Caribbean?
Criteria would need to be met and justification would be required before passengers could purchase a ticket.
That would cut down on problems with airport congestion, reduce ATC requirements Nationwide and would be good for the environment. Not to mention the background ambient noise reduction in large cities.
Kind of like rationing to save fuel and tires during WW2
