Efforts are on to develop Thuthukkudi (Tuticorin) Airport as the fifth international airport in Tamil Nadu.

Airport Director N Balsubramaniam told media in Thuthukudi today that the airport is likely to be declared as an international airport within four years.

He said that as the first step, night landing facilities will commence from Thuthukudi by next May.

International flights are already being operated from four airports of the state including Chennai, Coimbatore, Madurai and Trichy.
