If I have a lie-flat business class option with decent food, getting to my destination a few hours early with less comfortable seating isn't a clear win. Like most people, I'm not jetting over to London to have lunch and sign a deal and heading home to sleep in my own bed.

Thank you for enlightening me. As someone nowhere near rich enough for this to be relevant, my upper bound for pleasant W-E transatlantic flight is being able to sleep. Shortening that sleep seems like a loss. But if you have a private jet on call, you can skip connecting flights, airport security, schedules, and all the things that actually make flying slow and miserable. I guess this company is aiming at the people who don’t quite have that kind of money.

Flying can still be a hassle flying business/first mostly because of cancellations/schedule changes--which can still happen otherwise because of weather, air traffic, etc.--but is less frequent I assume. A lot of the hassles of commercial flight (security lines, lack of overhead space, airport crowds in the waiting area, cramped seating, etc.) can be mitigated to a significant degree however.
