It might end up being better ... seats further apart, food served and cleaned up afterwards by the plane personnel. Ticket prices will be higher meaning less air travel meaning less mixing of people.
To obtain those things you mentioned, coupled with less volume of passengers actually flying, would make ticket prices soar into the stratosphere. I am not talking about a few percentage points, but a gargantuan increase in cost.
Again, I fear the industry will never be the same.
