Right now when you goto Manage Routes > Destination View > Flights, the number listed is the number of Flight numbers you have on the route. So if you fly somewhere everyday a week it shows 1 or if you have 7 day scheduling it shows 7. This doesn't really tell you anything of importance, especially if you have some flights everyday and some using 7-day scheduling (like I do). I have some destinations I fly to 7x/day and some are just 7x/week and it is indistinguishable in the current view.
I think this column should be replaced with "weekly flights" so you can better tell what you're looking at. So if you have 1 flight number going everyday or 7 flights going once a day, the weekly flights will show 7 either way.
