I get a lot of Westjet Flights in and out of CYYZ, and never once has it populated the route since it uses non standard Flight ID's..
However tonight, I just had one populate...
Mode S was C04C36, Flight ID was 739, Registration C-GCWJ and the route was CYYZ-CYDF
The route is incorrect however..
Can anyone explain how this one slipped through with a route?
