Bhubaneswar(BBI) is an airport in the eastern India. I have used this airport from 2006 till 2012.
This airport is a very basic one, where a pax can’t expect too many facilities. A very basic terminal with minimum necessary infrastructure.
There are talks going on of making it a international airport. Whereas Orissa has lots of international business, still it looks like that making BBI will not serve any purpose, except boosting the ego of locals. Kolkata is under 1 hour of flying time. Since Kolkata is already established as a major international airport of India, there is no point in making BBI another one.
