I'd like to see a link of fuel burn based on either the number of pax transported or the seating configuration.
Fuel burn varies by weight of the aircraft so the more people & cargo (doesnt apply yet in AWS) fly, the heavier the plane and the more fuel an aircraft needs to burn.
Im not sure if your fuel number already takes this into consideration but when you change the configuration of an aircraft, the fuel burn/hr stays the same.
By linking fuel burn to configuration, having premium seats may become a more attractive proposition on shorter routes as currently they have no advantage.
I'm not sure how complicated it would be to implement this, but it would add a lot more realism to the sim.
glad to hear other people's thoughts.
