Mr. Ninan has forgotten a manjor point. Mumbai is way ahead in tax collections then Delhi. Tax collections are a direct barometer of a city's affluence. There is nothing much to read in flights cancellation. He seems to have forgotten that in North, Delhi is the only major airport while in West, Ahmedabad and Pune have taken away a slice of Mumbai's traffic. Because of difficulty in adding one more runway in Mumbai, more and more airlines are increasing their flights from Ahmedbad and Pune which is not the case with Delhi.
