Travel delays

Transportation delays
In 1999 in European Union, one flight in three was delayed by more than 15 minutes, while delays exceeded 25 minutes on average between the end of March and mid-July, a period of some four months. The year before such delays occurred over a 3-week period only. As much as half the delays were attributed to air traffic management. The remaining delays were due mainly to saturation at airports and the way airlines function.
