Operations at the Indira Gandhi International Airport were affected on Friday after fog disrupted the schedule of around 30 flights.
Around 16 flights were delayed while one was cancelled and three international flight were diverted to other airports this morning, either due to operational reason or due to bad weather, airport sources said.
Three international flights, one of Air India (AI-946) from Dubai, one of Jet Airways (9W-017) from Singapore and one of Uzbekistan Airways (HY 421) from Tashkent were diverted to Jaipur and Amritsar arriving here between 2.30am and 3am as the visibility was poor at the airport.
Visibility started to deteriorate when fog began to envelop the airport around midnight and it forced the airport authorities to implement low visibility procedures.
Though there was fog at the airport on Thursday, it had no affect on the flight operations. Around 50 flights were affected due to operational reasons on Thursday.
