Major airports with annual passenger traffic between 1 and 1.5 million will be included in the process.
After privatising six airports, the government is set to privatise 20-25 more in the next phase, Airports Authority of India Chairman Guruprasad Mohapatra said today.
Last year, the government had decided to privatise airports in Lucknow, Ahmedabad, Jaipur, Mangaluru, Thiruvananthapuram, and Guwahati for operation, management and development through public-private partnership (PPP) model.
In February, the Adani Group bagged contract for five of the six airports.
The Adani Group were the highest bidder for Ahmedabad, Thiruvananthapuram, Lucknow, Mangaluru and Jaipur airports.
"We have privatised six airports; we are now planning to privatise 20-25 airports in next phase," said Mr Mohapatra.
"These 20-25 airports will be major airports with annual passenger traffic between 1 and 1.5 million," he added.
Mr Mohapatra will take over as Secretary, Department of Industry and Internal Trade, in the Ministry of Commerce from August 1.
