The Centre was still undecided whether the modernisation of Kolkata's Netaji Subhas Chandra Bose International Airport should be done by Airports Authority of India or through joint venture, Civil Aviation Minister Praful Patel said on Monday.
Patel, who was attending a meeting of the consultative committee attached to the ministry in Kolkata said the final decision would be taken within a month after consulting the West Bengal government.
The West Bengal government had earlier approached the Centre for allowing AAI to undertake the modernisation work. It had disapproved the joint venture route which was followed in case of Delhi and Mumbai airports.
The ministry was in favour of taking a decision in a short period as the modernisation process was being delayed, Patel said. He also said unlike the West Bengal government, the Tamil Nadu government was keen on modernising the Chennai airport through joint venture.
On modernisation of 35 non-metro airports, Patel said that the list included Bhubaneswar, Guwahati, Dibrugarh, Agartala, Ranchi and Patna.
