Interesting! I wonder if they've been reading this forum? Or, more likely, it's part of the general trend to abolish* Route Direct.
* I noticed this trend a while ago, but someone has spoken to ATOC and they say it is confirmed that it is being (slowly!) abolished.
I still don't see why they don't hurry up (there's still loads of Route Directs out there!) or define it - at least as an interim measure.
