Are empty leg flights safe, or is there more risk involved?

When I was trying to get from NYC to Miami, I found empty leg flights and immediately decided this was obviously how the elite live and I too should give a try...

Like, it’s still a real jet, real pylotes, real mx, so I’m assuming the safety part isn’t 'sorry sir, this was the clearance rack Gulfstream.'

But the whole thing feels a little rS because the flight only exists if some other rich guy still needs the plane moved. So if he changes plans, do I just get deleted from the itinerary and left outside a random FBO with my duffel and my bad decisions??
