Really this is an exceptiomal Airport. The people employed in the Airport are also very very good.
There is an article about this airport in Atlas Obscura: http://atlasobscura.com/place/safdarjung-airport
I wouldn't recommend this airport for connecting passengers... Been through here twice and the airlines in question managed to lose my luggage on both occasions.. Also, the transit areas are cramped and not very comfortable, with virtually no facilities.. Hope the new terminal is better..
