The bigger picture
The "ATC" problems are not just ATC alone. The industry as a whole has not prepared themselves ready for such traffic levels. Inexperienced and insufficient ATC personnel (both front line controller and management), inadequate equipments, inexperienced air crews, insufficient gates at the airport, inaccurate weather forecast, etc etc. I hope people will not point their fingers to a small group of people who are actually suffering themselves. Have a look at the bigger picture and see for yourselves what the real problems are.
Also, how can you expect to operate a full schedule when the operating capacity of the airspace and/or the airport has been reduced significantly !?
