Ok on the airport map the small one when you look at the planes it shows where the from and where there heading to but when i click on the map to make it larger it doesn’t show it how come??? Hopefully it will show it soon.
Ive asked the same thing a couple times now, but haven’t gotten a response back from FlightAware yet either… 
It sucks too cause that feature made everything so much easier when looking at the airport traffic map(s) to see where aircraft were coming from & going to, without having to sit there & type it in & track every single one down…hah… FYV: here(below) is the link to my post where Ive been asking the SAME thing…The beginning half of the page isn’t about that though, so scroll down to like the last bottom 4 posts at the end…Hope we get an answer soon!
