How should the 50:50 rule be implemented, when pilot and co-pilot have not the same invoice rules.
E.g:
Pilot is 30 years old with normal price conditions, and co-pilot is 18 years old with young-pilot special price?
Pilot pays an aircraft per minute, co-pilot has a yearly flat-rate?
Implementation proposal:
The invoice is created for the pilot and at the end, the invoice will be doubled (for co-pilot) with 50% discount each. In this case, the above examples are still a problem in general, but not a system implementation issue.
The FlightCostBalance feature 50:50 should be implemented for flights and deliveries.
