For most of my trips, a huge % of the travel time is outside the actual flight time. Trip to the airport, security, boarding, waiting to take off, and reverse on the other side (with addition of potentially getting a rental car). This can be solved without supersonic solutions (e.g. flying private), but adoption is low for business travel – is it too expensive?
Separately, I wonder if a lot of the demand is also obviated by in-air wifi.
You might also look at “semi-private” solutions like JSX, if they go where you want to go. Should significantly cut down on the time outside of the flight itself.
> adoption is low for business travel – is it too expensive
Yes. Most companies won't even spring for business/first class, which is 10-20% the cost of a charter. Unless your time is both limited and worth 4 digits per hour, it's not worth it.
