The runway with upgradation will be stretched to 1,830 metres and will make way for ATR-72 flights with 78-passenger capacity, he said at an event here.
More flights can be pressed into service from Belgaum after upgradation, he said.
Other related infrastructure work would be completed latest by February 2015, he said.
"We have handed over 400 acres of land to the airport authorities for upgradation. However, Airports Authority of India's demand is for more area and the government will try to acquire the required land and hand it over to them at the earliest," Jayaram said.
