Thiruvananthapuram International Airport is moving closer to a major transformation, with the Union environment ministry’s expert appraisal committee (EAC) recommending environmental clearance for a ₹136 crore city-side development project. The initiative, planned by Adani Airport Holdings Ltd (AAHL) at Chackai within the airport grounds, aims to reshape the capital city’s gateway into a modern hospitality and commercial hub.

The project will feature a 240-room luxury hotel, expansive food and beverage areas with over 600 seats, and world-class infrastructure across nearly 34,000 sq. m. Spread over two basements, a ground floor and four upper floors, the complex will rise up to 23 metres. Once clearances are finalized, the hotel is expected to come under a global five-star brand such as Marriott, Hilton or Intercontinental.

This city-side facility is part of the larger terminal expansion plan, "Project Anantha" The project faced delays after the state environment impact assessment authority (SEIAA) sought changes in the basement design, citing environmental risks. The revised proposal has now cleared hurdles, and with pending cases moved to the Ministry of Environment, Forest and Climate Change (MoEFCC), the project is finally back on track.

Construction could begin within three months. Alongside enhancing airport facilities, the project is expected to generate around 300 direct jobs and nearly 900 indirect employment opportunities. “The project will not just address rising accommodation needs but also give a strong push to Kerala’s hospitality sector,” said a source close to the airport.

The EAC has attached strict environmental safeguards. Construction will rely on recycled water and rainwater harvesting. Once operational, the complex will need 318 KLD of water, with nearly half supplied by an in-house sewage treatment plant. Solid waste, expected at 418 kg daily, will be processed sustainably—biodegradable waste will be converted on-site while non-biodegradable material will be handed over to authorized vendors.

Other eco-measures include rooftop rainwater harvesting tanks, a 20% reduction target in energy use, and transplantation of 40 trees within the airport boundary. The land, currently serving as open parking, was allocated to AAHL under a 50-year concession agreement signed in 2021 with the Airports Authority of India (AAI). The EAC has clarified that the site is free from ecologically sensitive zones, coastal regulation restrictions or protected habitats.

Thiruvananthapuram airport is already handling record traffic, with nearly 4.9 million passengers between April 2024 and March 2025, and this new city-side development is expected to further elevate the airport’s standing as a gateway to Kerala.
