On one flight checked Flightstats showed 0 in bizz and 9 in coach. Actual were 0/12. But the killer was on checking another flight, Flightstats did not even show a direct flight with lots of seats available. It only listed several multi-connection route options. I checked also against the airline website seat maps which were closer than Flightstats. I'm a bit bummed because a tool like this would be fantastic. The big question is where is Flightstats getting their info.
