The government is expected to offer 6-10 airports in the next round of privatisation, for which the Airports Authority of India (AAI) is exploring a new model wherein a profitable airport and a non-profitable airport will be clubbed together before being brought to the table. In an interaction with reporters Thursday, Civil Aviation Secretary Pradeep Singh Kharola said that a major advantage of public-private partnership will be that the resources of AAI, which are tied up with these airports, “will be liberated”.
