Slight thread variation, but talking about the Metron system in general....
Problem is Bloggs is that after adhereing to a COBT, wheels-up at specified time some operators are still getting between 5-25+ mins enroute holding on CAVOK days then watching the two preferred operators get track shortening plus 300KIAS on descent and we watch them fly over the top at 15nm to run the VOR as we have been sitting on our "gifted" 210KIAS for the last 50nm. We then get to sit behind them at half the speed we want to be down their vectored long final. We miss our slots, our passengers miss their connections, we suffer busted slots for the rest of the day due consequential delays due to the first sector delays, pay our fines for missing those slots, go broke and ASA get to bleat about just how much money they are saving the industry etc on their recorded on-hold phone prattle.
See the issue clearer now? It is much easier and fairer to pre-allocate a realistic feeder fix time (say 50nm from the nominated airport) and should be available half an hour before due airborne and have the aircrew have to make that time or go away until they will fit in... Makes kids sharper you might say... especially when they get the "please explain" from the boss...
That way, the only thing that would cause any extra track miles or holding would be a WX at or around the SAM/PRM's etc.
