The government will soon announce a policy on construction of greenfield airports across the country to meet growing air traffic demand. "A consolidated and updated policy on greenfield airports is under consideration of the government,' civil aviation minister Praful Patel said in Lok Sabha in the question hour session. Asked whether airport projects allow developers to use 10%-15% of the allocated land for building malls and hotels, Patel said,"Land use at airports owned by Airports Authority of India (AAI) is governed by the provisions of AAI Act, 1994 and local laws whereas at other airports is governed as per the local laws,' the minister said on Thursday.
