Alan,
Thanks for that. Incidentally, just had an Alitalia on with a flight ID of AZ063 with his correct routing of LEMD-LIRF showing. Not sure if it is of help but could it be the case that if a 2 letter flight ID is given followed by a leading '0' that the route details are being given but if a 3 letter flight ID is given followed by a leading '0' the route details do not show. Maybe of some use to the 'techie' department.
