This is a plot of relative Air Traffic Volumes (passengers) in India for June 2018. Roughly, darker and thicker lines represent proportionally higher passenger volumes on routes.
Notice, how apart from Delhi, there is almost no major hub in the northern part of India. 
India is gradually cleaving into two distinct halves with one having (in relative terms) significantly higher presence of corporates, industries and organized employment. 
Using Nagpur as the marker for central India and analyzing North and South relative to it. 

For the entire country, for ever domestic journey: 

At least one among source/destination above Nagpur (N) 70.89%
At least one among source/destination below Nagpur (S) 72.54%
Both source/destination above Nagpur (N-N) 27.45%
Both source/destination below Nagpur (S-S) 29.10%

Now if we remove Delhi, notice how the first and third number dramatically drop.

At least one among source/destination above Nagpur (N) 53.06%
At least one among source/destination below Nagpur (S) 86.35%
Both source/destination above Nagpur (N-N) 13.64%
Both source/destination below Nagpur (S-S) 46.93%

This kind of a drop is not seen if we remove (individually) Mumbai or Bangalore or Hyderabad. 

Removing Mumbai: 
At least one among source/destination above Nagpur (N) 75.55%
At least one among source/destination below Nagpur (S) 63.23%
Both source/destination above Nagpur (N-N) 36.76%
Both source/destination below Nagpur (S-S) 24.44%
