b.r.g.t. these problems are systemic - the airlines are the ones suffering the consequences and are the major "customer" and are the ones with all the evidence to back up their claims. Controllers certainly don't have access to any of those details, so who else is going to be able to push to get things fixed?
"Too many aircraft arriving at the same time" is exactly the problem. If it's costing too much money then push to do something about it. Don't just keep firing aircraft in at some theoretical rate you'd like to be able to
knowing they'll be delayed by the actual conditions as they exist.
Shocking thought isn't it
