At least four flights to and from Delhi airport were delayed and one was cancelled due to dense fog in the national capital on Saturday.
Due to dense fog, only CAT IIIA and CATIII B compliant aircraft and pilots can operate, Delhi International Airport Limited (DIAL), which operates the IGI Airport, said.
Passengers are requested to contact the airline concerned for updated flight information, it added.
Dense fog shrouded Delhi and other parts of north India early Saturday leading to poor visibility in the region, which is in the grip of a cold wave.
