She’s the most famous performer in the world.

If she needs to fly private (which she does, her itineraries would never be possible on commercial, aside from the harassment she’d receive from the general public), it’s because her fans actually demand it.

Thats the problem. It’s not the jets, it’s that she’s expected, by millions of people, to stick to an itinerary that’s unattainable without them.

If you have enough fans to be the most famous performer in the world, and they demand you do things that are unattainable without a private jet, then you either need a private jet, or saner fans.

Stop looking at the immediate problem. Look upstream. Don’t build a dam at a delta.
