The same disease has spread to India. There are eight commercial airports with no scheduled flights at all - Ludhiana, Puducherry, Cooch Behar, Akola, Bikaner, Jaisalmer, Pathankot, Kadapa (AP). This list changes - for instance, flights to Belgaum start and stop - but its clear that even for significant cities like Ludhiana, there's isn't enough traffic.
Similarly, the Plan Panel says that the existing 17 "world class" international airports are underperforming, and that there is no need for further such airports.
