Why are my flights always so late ?

My morning flights are always very late and there is a lot of rush on the airports. It got me thinking. How many planes are actually in air at a given moment? I got hold of some data of airline schedules and tried to plot it on a map(Google). This is a snapshot of the same.


Red bubbles show approx. location of a flight in air. Red lines show the path.
It depicts Indian sky at 8 in the morning. Some 414 flights in Air!
