Other interested players include GMR, GVK, Essel, Siemens, Flemingo, IBDF Zurich and Cochin International Airport.
Thousands of Airports Authority of India employees meanwhile staged demonstrations at airports across the country today to protest against the government's attempt to privatise Chennai, Kolkata, Jaipur and Ahmedabad airports, in which AAI has already invested Rs 5,000 crore.
Its employees' union has also warned the government of blocking airports if it does not drop its plan.
"As many as nine players including the international companies have shown interest in the modernisation of the four airports for which the AAI had invited Request For Qualification (RFQ) early last month," said a source.
Sources said GMR Airports, GVK, Tata Realty, Essel, Adani Ports and Special Economic Zone, Siemens Postal Parcel and Airport Logistics, International Business Development Flughafen (Zurich), Flemingo Duty Free Shop Pvt Ltd and Cochin International Airport have shown interest in taking part in the modernisation of these airports.
Sources also said that the private players have sought from AAI longer concession period than the 30 years as stipulated in the RFQ besides traffic growth and tariff projections.
Earlier, the UPA government had proposed to privatise six airports - Chennai, Kolkata, Ahmedabad, Jaipur, Lucknow and Guwahati but the plan failed to take-off during its tenure.
Taking the previous government's agenda forward despite a stiff opposition from the AAI union, the new NDA government had said it would privatise only Ahmedabad and Jaipur airports and not hand over Chennai and Kolkata airports to the private corporates as it has already invested public money to the tune of Rs 5,000 crore in their modernisation and upgradation.
It, however, left out Guwahati and Lucknow airports from the agenda as these loss-making airports do not have enough volumes to attract private players.
Airports Authority Employees Union (AAEU) General Secretary Balraj Singh Ahlawat, who led the demonstration at AAI headquarters here, said: "The government, rather than asking the private corporates to develop greenfield airports, is giving away its own airports to them on a platter. We will not let it happen."
He said the private players are eyeing only those airports which are "revenue generating" for the AAI.
