The third party app “Ultimate Traffic” was able to show both the departure and the destination airport of ai planes within FSX. It would be nice if this option would be added to MSFS and possibly even extend to player aircraft.
Looking at the Live Traffic IDs something came to me that might be a must have for them people would probably love. The ability to see where they are going as well as where they came from, or even an auto switch, or manual, or even just visualize both.
Flying over KBOS and many planes getting ready to depart and most say KBOS as in departing.
I think it would be more interesting to see where departing flights are going rather than where they are.
You could enjoy ghosting along without having to go to Flightaware and scout it out… far easier to get more of a casual, hey, they’re going my way, I wonder how we’ll match up?
You could do any number of deployments, show both, toggle or even have them switch locations halfway when they stop being departing and become arriving.

It would be great if you could include both the departure and arrival codes when viewing other aircraft in the game. You only display one ICAO code instead of both.
Yes it would be nice,however you can use Littlenavmap. I have it running on a separate screen and can view both codes.
