One other factor is that for many of today’s 20 year olds, flying 12 times a year is normal. (They will lecture you on green issues, while ignoring the two litres of Jet A a second, per engine each flight uses… but there you go.)
Many fly from airports where they never see the outside of an aeroplane, and for them the flight has all the magic of a crowded sub-way ride – window blinds down to make looking at the screen easier.
Difficult to get any enthusiasm from the experience.
