Findo,
I am only going on what I was told when I was up at ScATCC not long ago. I plugged in next to both Tyne and Humber listened to aircraft check in and push for direct-track to a cetain reporting point rather than routing around the MDAs. I am aware that they will routinely do this to save as much fuel as possible and they were obviously 'chancing it' becuse they weren't too worried when the controller told them to route around. However, I heard that amongst others, KLM had expressed huge displeasure about the MDAs. It is only heresay so we'll have to see what happens.
Regards
