I do admit that when I have moved aircraft myself I never thought about zeroing the passengers and cargo. I always just let the system do its thing and the transfer flights paid for themselves. Maybe a 'ferry flight' option in the charter flight page that sets passengers and cargo to zero and lifts the range restrictions (assuming ferry tanks were installed) would encourage more pilots to use it.
I am curious about when you said:
We have always been a very open boarders platform, you can fly and carry passengers any where you want, including between countries that are rivals/enemies where in the real world it would be impossible. I wonder if we should incorporate that here, probably not, I like our non political world we have here.as we would not have Euro credentials to haul for profit, this would be US FAA part 91 ferry flight
