entry of security hold area.
The CISF said while it was elated by the result of the survey, there are areas which require improvement and "would be paid special attention".
"Efforts are being made to further improve performance of CISF based on these suggestions. Instructions are being issued to zonal Deputy Inspectors General (of CISF) to carry out in-depth study of the report and suggestions pertaining to the security units under their jurisdiction.
"Further, the suggestions pertaining to other agencies would be forwarded to them for taking suitable measures," the force said.
The survey could not be conducted at five airports at Lilabari, Tezpur, Shimla, Gwalior and Bhuntar as during the test period these facilities were not operating scheduled flights.
The aim of the in-house survey, the CISF said, was to "get feedback from passengers regarding quality of services being rendered by CISF and to assess the performance of airport security group personnel at airports in order to explore the shortcomings and to further improve their performance".
The force, in the analysis of the survey, said the amount of waiting time at security checks is dependent on the facilities provided by the airport operator to the CISF.
These facilities include availability of space, adequate infrastructure and entry time regulations by airlines based on capacity of the terminals.
