Now
there's a question.
I once worked for a large company who resorted to this on positioning flights using the argument that if you were landing without passengers it wasn't a commercial flight
as such, even if you were there to collect punters. Funny how the rest of the world disagreed but hey ho.
Personally I never had to get into the argument as none of those flights came my way but I spoke to few colleagues who had flown them and they described the experience as 'interesting'.
