Dense smog hampered visibility at the Delhi airport on Tuesday, affecting operations and leading to over 300 flights being delayed by up to two hours.
Poor visibility rendered one of the runways inoperable during the morning hours, leaving airport officials with just one airstrip of the total three to handle as many as 45 incoming and outgoing flights every hour.
Sources at the Indira Gandhi International (IGI) Airport said that due to low visibility on runway 9/27, they could only use runway 10/28 in the morning.
The third runway 11/29 was shut from Tuesday for three-days for maintenance.
The sources said that the second runway was opened after visibility improved.
