Maybe overnight flights should optionally let you sleep on the ground before/after the flight. Charge extra, you don't have to pay pilots or for fuel, park away from the gate.
You would need power without the engines but you could hook up a generator or a feed from the airport.
I've been on redeye flights where, a few hours in, the pilot came on the PA, told us about something to see out the window, and also about the drink we could buy from the flight attendants - credit cards only please!
Air travel is just endless indignities and discomfort.
