Pretty much agree with PilotLZ's assessment. The devil - as always - is in the detail though.
"Something close" = perhaps 70% to 80% of passenger traffic at a 20% to 30% increase (in real terms) in average costs/airfares???
This figures are not meant to be an analysis or anything - they are just plucked out of thin air (again, pun intended
). I'm just putting them up there to represent the concept: aviation is not just going though an event, it is also going through a longer term structural change, of yet to be seen size and shape.
As it always was going to do anyway, before any of us had heard of Covid19.
