Delhi as Primary Hub 
Air India recently made Delhi as its Primary Hub. This is very much true because Delhi has more Air India Flights than Mumbai. The reason for doing this was that Mumbai is over saturated and over-crowded compared to Delhi. Each and every new aircraft lands at Delhi during its delivery flight.
Paris and Tokyo now originate from Delhi and not from Mumbai. No new destinations are being launched from Mumbai compared to Delhi which has seen Washington,D.C. and Toronto flights. This is enough proof that Delhi is Air India's new Primary hub.
