"We have engaged US-based consultant Landrum & Brown, a few months back with a mandate to study sustainability and capacity expansion of the airport," Kolkata Airport director Atul Dikshit said today on the sidelines of a Confederation of Indian Industry (CII) organised event 'Infra-East'.
Landrum & Brown specialises in aviation planning and development.
Dikshit said on an average, 450 flights take off or land daily at the Netaji Subhas Chandra Bose International Airport here.
Dikshit said the West Bengal government had made efforts to persuade a few European airlines to start their operations from Kolkata.
"There are route conferences happening around the world. We visit to these conferences and try to sell out our airports. We have showcased Calcutta (Kolkata airport) in these route conferences. Till date, few have shown interest but no one has come out with a concrete proposal," Dikshit said.
