ATC are too busy trying to make all the RPT jets simulataneously speed up while slowing down, maintaining separation while keeping us all bumper to bumper and maintaining 180kts to zot miles while hoping we don't have to go around.
The whole system is stretched beyond capacity and its only going to get worse while governments allow airports and ATC to be run 20 years behind the capacity curve. Bad things are going to start happening in CTA some day, probably better off staying out of there.
