The Airports Authority of India (AAI) will choose bidders to operate six of its aerodromes on the basis of "per-passenger fee" and finalise the bids on February 28. This comes after government cleared a proposal to privatise six AAI-run airports. Airports in Ahmedabad, Jaipur, Lucknow, Guwahati, Thiruvananthapuram and Mangaluru are set to be privatised under this proposal.
