Try operating into New Delhi, Bombay, or Calcutta. Aviation in India is saturated all right. And whilst I cannot (and would not wish to) judge Indian pro pilot standards, ATC is variable, and the ignorami who govern the airports structure are numbskulls or corrupt. Possibly both. The major airports are appalling in terms of runways, taxiways, lighting, approach aids serviceability, terminals, immigration, usw. Charter colleagues report the same for places like Goa. All operators and ATC are forced to contend with high traffic loads, bad weather, and primitive facilities. Its not Bollywood.
No room for growth. Saturated.
