All of the search boxes (Private/Airline Trackers, Airport Info) all lead to 404’s when searching with them for me.
Looks like the forms correctly query flightaware.com (not discussions.flightaware.com), but the form feeds back a URL that’s on discussions. For me, these links come back as: discussions.flightaware.com/live/airport/KJFK
etc. These are all 404/broken links.
Apologies if this has been reported already!
