Not enough ground staff to make the operation work (through a combination of p poor management and sharp practices from the employees). Unrealistic flight and turnaround schedules for flight crew build in delays from the outset. Cabin crew sitting in the CAT lounge while the clock ticks towards their industrial agreement times. Unservicable aircraft add to delays wile the engineers work out how to use the expensive new stores computer. And all this added to operating out of Europes busiest and most overcrowded airport as a main base in airspace that is creaking at the seams.
