The Union Home Ministry will deploy an additional 1,200 personnel from the Central Industrial Security Force (CISF) at the Delhi airport - adding to the 5,000-odd already deployed - to ensure faster security checks and ease the holiday season rush, NDTV has learnt. Sources said the decision will be made at a meeting called by the Home Secretary after days of complaints that it's taking more than four hours, as opposed to the usual two hours, to complete the check-in process before people can board flights.
