Charter Flghts - Revenue

Is there any way to have a charter flight (free flight) automatically produce pilot pay and revenue for the airline?  I am thinking $25.00/passenger for pilot pay and 50% of the revenue  that the airline would receive for the same scheduled flight would be fair.

At the present time, the charter flight is being manipulated by admin during the PIREP acceptance stage.

I fail to see why any pilot would make a flight and receive nothing in return or why any airline would allow one of its planes to be leased free of charge.

 

Thanks in advance for any help
