Severe flog disrupted flight movements at Delhi leading to diversion of 17 flights on Sunday.
Visibility at Delhi airport fell below 50 metres (minimum level required for landing in low visibility conditions) on Sunday morning resulting in chaos.
Most of the flights were diverted to Ahmedabad and Jaipur. "Fog situation was severe and there were no vacant parking bays at these two airports due to diversions," an aviation source said.
Seventy-three flights were delayed and six flights including both departures and arrivals were cancelled due to low visibility, Delhi International Airport Ltd said in a statement.
