AMRITSAR, JUL 28 (PTI): The government aims to have a total of 44 airports, including 4 hub airports, to provide seamless international air connectivity, a senior government official said on Tuesday. Air India on Tuesday launched flights under the Hub and Spoke model from Amritsar, the second airport after Varanasi from where such fights have been started. Presently, there is one hub airport — Delhi — and two spoke airports — Varanasi and Amritsar. The model, that seeks to make India a global aviation hub, will enable seamless connectivity between Tier-II and Tier-III airports with international destinations through hub airports. Passengers arriving from smaller cities will be routed through major hub airports such as Delhi for onward international connections.
