In a new brief issued to the paramilitary personnel posted at the airport, they have been told to cut down on smiling.
It is learnt that the Central Industrial Security Force (CISF) has been asked to be more vigilant than friendly.
“We cannot be over-friendly with the passengers because one of the reasons cited as to why 9/11 happened… was excessive reliance on passenger friendly features,” CISF director general Rajesh Ranjan was quoted as saying.
Ranjan said CISF personnel will also be trained in behavioural analysis by international consultants.
India has witnessed a six-fold increase in passenger numbers over the past decade as citizens take advantage of better connectivity and cheaper fares in the highly competitive sector.
But airports are struggling to cope with the surge and analysts have warned that the government needs to spend billions of dollars to boost capacity and safety.
Earlier this month, the government said some domestic flyers would be soon able to leave their boarding passes at home, thanks to proposed facial recognition technology at airports.>
