In a data analysis, we discovered systematic gaps between the number of planned and the number of observed entries of aircraft into flight sectors. We also found that random disturbances of an arrival process cause systematic gaps. We conclude that even if all controllable uncertainties in flow planning were eliminated, systematic gaps between the number of planned and observed traffic would remain.
