A better approach would be rationing.
If air travel rationing would ever be implemented, instead of travel becoming a rich person's hobby (which it already is, for a very loose definition of rich, a definition loose enough that it also counts people with in-house bathrooms with running water and waste disposal systems as rich) it would become a powerful person's hobby.
Not that different IMHO.
But, just to be clear, I'm totally with you. It's just that I'm terribly pessimistic.
What kind of gives me little moments of joy is thinking of what the 3000 version of "Fall of civilizations" podcast will have to say about what is happening now.
> It is estimated that around 95% of the world’s population has never experienced air travel firsthand.

Regarding jets vs mass transport, I think it is misleading to oppose them. Remove all the jets on the planet and we’ll have exactly the same sustainability trouble.
My old dad points the fault of rich people taking jets to go everywhere, and also the fault of "billion of Chineses starting to take more and more flight". His bi-monthly usage of plane for Holliday isn't worth considering through because he "has no choice, people have right to takes Holliday and we-the-world-middle-class are not the problem"
