The terminal became defunct after a new international airport building came up nearby in October 2016.
To utilise the old building, airport officials decided to rent it out for private functions.
So far, the building has hosted a nine-day Navratri festival, a Sindhi religious event and a Bollywood film shoot.
"We have been doing it to increase the revenue while adhering to the Airports Authority of India's guidelines and without compromising on security. Bursting crackers is not allowed. The organiser has to pay for the deployment of security personnel," Singh said.
Inside the terminal there are four sections which can be rented separately. The rental is much lower compared to what private venues charge, Singh said.
The venues are rented out either for a monthly fee or for shorter, single events.
For the 10,000-sq meter ground in front of the building, the rent is Rs 222 per sq meter for a month. For a non-AC hall inside, spread over 13,000 sq metre, the rent is Rs 780 per sq meter per month.
The airport earned Rs one crore in rent when a Navratri festival was staged on an open plot on the premises for nine days last year, Singh said. The building can also host mega-exhibitions and fairs, he added.
