Flight operations at the IGI airport in New Delhi remained normal for the second consecutive day on Friday due to absence of dense fog.
"All flights were operating as per schedule as the airport has not witnessed any fog since last night and runway visibility remained over 2,000 metres through the night and this morning," an airport official said.
Though visibility dropped a bit after 7 am due to shallow fog, it did not cause any disruption in flight movement.
The Indira Gandhi International airport has witnessed a total of 172 hours of dense fog this month, breaking the record of 168 hours of January 2003. Over 1,200 domestic and international flights have been disrupted this season.
