Planes have certain range which is available for max payload.
However if I configure a premium heavy cabin, does it mean that I get to fly further without payload restrictions ?
I would assume that 100 premium seats + PAX weigh less than 160 Standard seats + PAX ? Is there a way to figure this out during the cabin configuration process so that I do not have to actually assign the cabin to an aircraft to try it out (and loose money in the process...).
A simple formula to compute max payload weight for each config would do the trick ;-)
