It isn't a big secret what kind of passenger or cargo loads airlines carry to their employees who have access to operational data, which crew members do. Pilots and FAs and ground staff obviously know what is revenue pax and cargo and how much of each goes on each flight, even if they have to swap info with each other to get the picture. The nice DOT summarizes it all for the public as well.
WT, I don't know about others, but I have never had a clue (nor particularly cared) about how much cargo was in the hold. AFAIK, the only cargo info given to the captain is total weight and (if applicable) the nature of any hazardous cargo because he has to sign off on and approve transport of hazardous materials. (Say, for instance, a case of high-energy lithium batteries.)
I've never heard an agent, a pilot, or a f/a mention the value or revenue from cargo. But, then I'm a flight attendant. I'm paid to be cute, not smart. CORRECTION: I just remembered years ago before I was furloughed in 2003, I was working a flight from DFW to somewhere (that I don't remember), and we had something like 30 passengers on board. I said to the captain that I had never seen more than 50 people on any plane going to our destination and wondered why we bothered flying the route. He said that if it weren't for U.S. Mail contracts, we wouldn't fly that route, but that we made enough money from the Post Office to make the flight at least break even.
