It seems from the arrivals controller point of view that things have improved slightly over the past few weeks. Maybe the new system is doing it a little better, maybe not. There's been a discussion amongst us that non conformers or those being punished should be sent to an arbitrary waypoint off the published route (maybe called NORTY?) so that they aren't causing grief in a pattern while everyone else is coming through?
One bizarre trend that has become apparent is that when the big delay notams go out, there actually seems to be a lot less holding. Is that coincidence or do the notams encourage flights to be more time compliant?
