Does an aircraft know (or care) whether it is tankered fuel or payload ?
It's just weight, to be carried for some hours, surely.
Just occasionally as crew with an otherwise empty positioning flight, we might find a payload.( A load of soapflakes was one that the airline carried !)
Later I chartered a Britannia to three passengers who were going my way. The money went into my Flight Account. ANY additional revenue was welcomed by some companies.
One of my employers condemned this practice. as it implied that their salesmen were not finding that work. ( That Captain went on to found his own successful airline.)
