I think this needs to be addressed. Athens so far has generally been ok - however there have been issues.
By far the main one which I have seen this morning is separation conflicts - pilots not being respectful and slowing down to the speed of the aircraft ahead of them - meaning ATC has to remind them (several times in some cases)
In just 6 hours I saw loads of go arounds due to separation conflicts and many people getting ghosted for separation reasons or not exiting the runway quickly when told to do so.
IFATC are doing a great job trying to manage the large flow of traffic - keep it up guys.
