A rational, data-driven case. Not against a second airport for Chennai — against building the wrong airport at the wrong site for the wrong price.
We need a second airport for Chennai. But a ₹27,400 crore greenfield on a site that is one-quarter water, 70 km from the city, displacing 13,000 people, requiring another ₹11,000 crore in metro connectivity — that is not smart infrastructure. It is a fiscal gamble dressed up as ambition.
The Parandur project was announced in 2022, passed through the Greenfield Airport Policy process, received in-principle clearance from the Ministry of Civil Aviation in June 2025, and acquired over 1,100 acres before the TVK government scrapped it in July 2026 — citing, among other reasons, that the site contained 800–900 acres of water bodies that made runway construction technically and economically questionable.
The predictable response from the pro-development corner of X was outrage: "AAI said it was feasible." "TN will lose investment." "Lakhs of jobs lost." "TVK is anti-development."
This site examines those claims — not through an environmental or farmer-sentiment lens, but through the very economic and planning logic that the airport's proponents claim to champion. Opportunity cost. Demand projections. Fiscal prudence. Site economics. Policy process.
Every argument here starts from the same premise: Chennai does need additional aviation capacity. The question is whether Parandur — at ₹43,000+ crore, on waterlogged land, 70 km from the city — is the right way to get there.
