Mental model:

Electricity->Batteries, renewables, geothermal, hydro, transmission, cross country interconnectors

HVAC->Heat pumps, low carbon district heating, insulation, sand heat batteries

Mobility->Electric vehicles, bikes, scooters, light rail, heavy duty electric vehicles

Marine traffic->Low carbon produced methanol or ammonia

For air travel that must remain and cannot be replaced with an electrified or low carbon alternative (until low carbon solutions exist), the component that must remain be made as efficient as possible. Regardless of wealth, you fly commercial, just like everyone takes the subway, regardless of wealth or status, in cities with high quality mass transit. Your need is met, just within our collective societal tolerance for the harm incurred for the travel desired (Point A->B).

We may disagree, and that’s fine. I believe the climate data is clear as an input to this decisioning. Whether you’re wealthy should not be a factor in outsized carbon emissions (private jet travel, specifically) simply because the socioeconomic system is defective on this. I assume the appetite for this goes up as climate change consequences become more dire, compelling more appetite for extreme actions to course correct.
