I didn't notice this on any thread before, even after searching. If it's been posted, sorry, I missed it.
From what I can gather (as a relative newbie), the flights fill up with pax according to flight rating. This can be found in the ORS, and that's great when trying to determine what routes might help. I can move my mouse over and see what the flight rating is. When I look at an individual flight through Fleet Management > A/C > Details > Flight Rating, there's no number that pops up to let me know what the rating of that particular flight is/was.
Instead of having to search for my flights in ORS, I'd like to suggest having that same 'pop-up' number notification be available in the Flight Rating page of the individual flight.
