Everyone I know who flies private optimized their time way beyond what you described. Is your experience different?
I think it just shows that either a. The time argument is a rationalization or b. It’s socially more acceptable to spend money largely out of sight on corporate aviation, rather than having people in your everyday life see an enormous household staff
There is a video (and I believe it's linked in this thread) about a Walmart exec visiting stores across the country. It's likely in some small to medium sized town with a regional airport. If they meet with the team from 9-12 and the next flight out isn't until 5pm, they are wasting that time waiting. Instead they fly their plane in, meet, fly out at 12:15 and are in the next town with the next manager in 45 minutes.
It's just that a $500 town car for the day is more practical than having a chauffeur fly with you to Hong Kong, Bali or Cannes...
What makes you think this? I would have thought the bar for getting a personal trainer or a housekeeper is far far lower than the bar for people getting corporate aviation? Many middle class people manage to afford a personal trainer and housekeeper.
Put another way, corporate aviation costs several thousand dollars per hour of time saved, and most people that use it have not exhausted time savings that are easier to come by
That said I think there's also something in the social acceptability of services being higher than that for servants.
It’s hard to find the time to hire people.
Also fair to mention that it's not as much of a time savings too but convenience they can afford. But they mainly by time on NetJets, and not the jet.
