This would be simple, but I fear it could be laggy. I notice that you have the runways of other non-destination airports on the map, as the little grey lines, what if when you clicked on one of the said grey lines, a text box with the airport name showed up? I often get curious while tracking a flight, or if one goes directly over an airport, I can affiliate that airport with a particular route/VOR. Again, small but maybe time consuming/laggy.
